Abstract
I examine whether mandating the disclosure of investments influences firmsβ strategic interactions. I exploit an SEC regulation requiring firms to report off-balance sheet purchase obligations, such as commitments to inventory purchases, CAPEX, R&D, and advertising. Motivated by theory on strategic investments, I predict and find that firms respond to the regulation by increasing investments if they have substitutive product market strategies with competitors, and decreasing investments if they have complementary strategies. This two-way finding is consistent with firms using investments to influence competitorsβ behavior in ways that increase their own profits. I show that changes in investments are concentrated among firms with large market share, which have a greater ability to influence competitorsβ actions, and that they have real effects on firmsβ sales and profit margins. Collectively, my results illustrate a novel channel through which financial reporting shapes firmsβ investments and competition.

1. Introduction
I examine how mandating the disclosure of investments shapes firmsβ strategic interactions.
Specifically, I study the effects of a regulation requiring disclosures of off-balance sheet
investments on firmsβ strategic investments. My study is motivated by the idea that investments
are more likely to affect competitorsβ behavior when they are observable, and thus that mandated
reporting increases the extent to which firms strategically change their investments to affect
competitorsβ behavior. My findings provide support for this idea and, in doing so, suggest that
increased disclosures about investments have real effects on competitive dynamics.
Following the literature on strategic investments, I define investments to be activities that are
(partially) irreversible and time-bound. The first implies that they cannot be cancelled without
incurring some losses or costs, and the latter implies that they need to be executed in a timely
manner before production or sales. Activities with such characteristics signal credible
commitments to future strategies (e.g., von Stackelberg 1934). Therefore, consistent with prior
literature, I consider a wide range of activities including inventory purchases, CAPEX, R&D,
advertising, marketing, etc. (Ellison and Ellison 2011; Bloomfield and Tuijin 2019).
My study exploits a regulation (hereafter βthe regulationβ) implemented by the U.S. Securities
and Exchange Commission (SEC) in 2003 that requires firms to disclose in their 10-Ks off-balance
sheet purchase obligations. These are minimum or non-cancellable future expenditures, such as
payment obligations for inventory purchases, CAPEX, R&D, and advertising. This regulation is
well suited for my study, because purchase obligations are irreversible and timely, which makes
them effective at signaling commitments to future product market strategies.
Intuitively, the specific investment strategy that firms choose likely depends on how they
interact with other firms. Accordingly, my predictions for how firms respond to the 2003
regulation depend on their mode of competition. To guide my predictions, I rely on classical theory
2
on strategic investments developed in the industrial organization literature, which classifies
competition into two types: competition with strategic substitutes and competition with strategic
complements (Fudenberg and Tirole 1984; Bulow et al. 1985).1
Firms are considered to be in competition with strategic substitutes when more aggressive
strategies, such as increasing quantity, induce competitors to adopt less aggressive strategies by
reducing competitorsβ marginal profits. For example, suppose Coca-Cola signals that it intends to
flood the market with soft drinks by making large investments in distribution centers. Coca-Cola
would be classified as having strategic substitutes if these investments induced smaller competitors,
such as Shasta, to reduce the quantity of production in anticipation of a reduction in the prices
consumers are willing to pay for their products. Thus, in competition with strategic substitutes,
firmsβ choices have negative correlations.
Firms are considered to be in competition with strategic complements when more aggressive
strategies, such as lowering price or increasing quality, induce competitors to similarly adopt more
aggressive strategies by increasing competitorsβ marginal profits. For example, suppose Boeing
signals that it intends to increase the energy efficiency of its aircraft. Boeing would be classified
as having strategic complements if these investments induced smaller competitors, such as General
Dynamics, to also improve the quality of their aircraft to avoid losing market share. Hence, in
competition with strategic complements, firmsβ choices have positive correlations.2
I develop a two-way prediction that, after the SEC regulation, firms in competition with
strategic substitutes increase investments, and those in competition with strategic complements
reduce investments. In the examples above, Coca-Cola increases investments in distribution
1 See Appendix C for detailed discussions on competition with strategic substitutes and strategic complements. 2 Competition with strategic substitutes is commonly referred to as Cournot competition, and competition with strategic complements is commonly referred to as Bertrand competition. This categorization holds true under general conditions, such as when demand is linear and marginal cost is constant (e.g., Bulow et al. 1985).
3
centers, and Boeing reduces investments in energy efficiency. The intuition is that firms desire to
induce less aggressive strategies from competitors, as this helps increase their own profits, and
greater observability of investments increases firmsβ ability to use investments as a signal to induce
desired responses from competitors. To induce less aggressive strategies from competitors, firms
with strategic substitutes signal commitments to more aggressive strategies, whereas firms with
strategic complements signal commitments to less aggressive strategies.
The predictions from classical models of strategic investments center on firms with a first-
mover advantage (Fudenberg and Tirole 1984; Bulow et al. 1985). Accordingly, my predictions
center on dominant firms (i.e., those with large market share), which have the capacity to exert a
significant influence on the quantity and price of products in the industry, and hence on the
subsequent actions of other firms (e.g., Gisser 1984, 1986; Lieberman and Montgomery 1988).
To test my predictions, I employ difference-in-differences tests around the regulation on
dominant firms. I examine whether dominant firms with a greater increase in investment
observability (i.e., a greater degree of βtreatmentβ) change investments by a greater amount. To
estimate the degree of βtreatmentβ, I count redacted investment contracts as manifested in 10-K/Q
and 8-K exhibits before the regulation.3 Because the regulation increases disclosure of contractual
investments, firms that redact more investment contracts in the pre-period likely experience a
greater increase in observability of their investments.4 To partition firms into different competition
types, I use a measure developed by Kedia (2006).
3 To count redacted contracts related to investments, I conduct a textual analysis similar to those of Verrecchia and Weber (2006), Boone et al. (2016), Glaeser (2018), and Bourveau et al. (2019). See Section 4.1 for details. 4 I use the unscaled number of redacted contracts, not the ratio of redacted contracts over all investment contracts. This is because the extent of firmsβ use of contractual investments has large across-firm variation. Using the ratio imposes an assumption that firms equally rely on contractual investments. I also validate using the unscaled number in Table 7, where I show firms with more unscaled investment contracts are more likely to have a greater amount of purchase obligations.
4
My tests examine changes in firmsβ investments recognized in financial statements from the
pre- to post-regulation period, because firmsβ off-balance sheet purchase obligations are not
observable prior to the regulation. Thus, an assumption of my empirical design is that off-balance
sheet purchase obligationsβsuch as inventory purchases, CAPEX, R&D, and advertising
expensesβare soon reflected in financial statements under corresponding items. This assumption
seems reasonable given that purchase obligations reflect non-cancellable amounts of payments.
Consistent with my predictions, I find that dominant firms with strategic substitutes are more
likely to increase their investments if the 2003 regulation makes their investments more observable.
In terms of economic magnitudes, a one-standard-deviation increase in the exposure to the
regulation leads to an approximately 5% increase in investments for an average firm. In contrast,
dominant firms with strategic complements display a change in investments of similar economic
magnitude, but of opposite sign. Specifically, they are more likely to decrease their investments if
the 2003 regulation makes their investments more observable.
I also document that dominant firms with strategic substitutes primarily increase investments
in capacity (e.g., inventory purchases and CAPEX), whereas those with strategic complements
primarily reduce investments in product differentiation (e.g., R&D and advertising). These
findings are consistent with firms using differing levers depending on their mode of competition
(e.g., Kreps and Scheinkman 1983; Singh and Vives 1984). Specifically, my finding that firms
with strategic substitutes increase investments in capacity is consistent with these firms being more
likely to compete in quantity, and aligns with the example above of Coca-Cola. My finding that
firms with strategic complements reduce investments in product differentiation is consistent with
these firms being more likely to compete in quality, and aligns with the example above of Boeing.
To sharpen my main inferences, I show that the divergence in investments in each type of
competition only emerges after the 2003 regulation, consistent with firms displaying parallel trends
5
prior to the regulation. I also run falsification tests showing that firms do not appear to change
expenditures on acquisitions or operating leases, which are informative about future strategies but
whose disclosures are not affected by the regulation.
To understand the consequences of the strategic actions taken by dominant firms, I also study
the behavior of non-dominant firms. I find that they decrease investments after the 2003 regulation
across both types of competition. Continuing with the above examples, the decrease in investments
by non-dominant firms with strategic substitutes is consistent with Shasta rationally reducing its
investments in production when Coca-Colaβs increased investments signal an intention to flood
the market. In contrast, the decrease in investments by non-dominant firms with strategic
complements is consistent with General Dynamics optimally engaging in less aggressive
investments in technology when Boeingβs reduced investments signal reduced commitments to
improving energy efficiency.
I corroborate my findings by analyzing the costs of goods sold (COGS)βwhich increase with
the quantities soldβin each type of competition. I confirm that firmsβ investments foretell their
aggressiveness, proxied by COGS (i.e., investments are not βcheap talkβ). Furthermore, to help
substantiate the effect of dominant firmsβ strategic investments on competition, I show that, after
the 2003 regulation, dominant firms with strategic substitutes increase sales by capturing larger
market share, and dominant firms with strategic complements increase profit margins through less
intense competition. These findings suggest that dominant firmsβ strategic investments have real
effects on product market outcomes.
In the final section of this paper, I perform a series of tests to validate my methodology and
confirm the robustness of my main findings. First, I show firms with more investment contractsβ
redacted or non-redactedβbefore the regulation are more likely to report greater amounts of
purchase obligations after the regulation. This positive relation supports the assumption for my ex
6
ante βtreatmentβ measure that firms with more redacted investment contracts experience a greater
increase in their disclosure of contractual investments. Second, I verify that amounts of off-balance
sheet purchase obligations positively predict amounts of investments subsequently reported. This
suggests that purchase obligations are soon reflected in investments, and thus validates my tests
examining changes in investments from the pre- to post-regulation period. Lastly, I confirm that
my results are robust to using alternative proxies for competition type used by Bloomfield (2019),
using a dichotomous βtreatmentβ variable, and using a shorter period excluding the dot-com bubble.
Readers may ask why dominant firms did not engage in strategic investments prior to the
regulation by voluntarily disclosing their future strategies. Disclosing future strategies may be
considered as anti-competitive practices and it increases the risk of antitrust investigations
(Antitrust Guidelines for Collaborations Among Competitors April 2000; Steuer et al. 2011;
Bourveau et al. 2019). The SEC regulation likely provided firms with legitimate channels to
increase their disclosure about future strategies. Therefore, my findings add to growing evidence
on potential conflicts between antitrust and securities regulations (e.g., Bourveau et al. 2019).
Also, while I interpret my results in light of the theory on strategic investments, readers may
be concerned that they are driven by alternative channels through which financial reporting affects
investments, such as an increase in proprietary costs (e.g., Verrecchia 1983; Ali et al. 2014). The
theory I rely on yields a two-way prediction for dominant firmsβ investments that specifically
hinges on their competition type. Although alternative explanations can account for some aspects
of my findings, I am not aware of any theory that would explain opposite changes in investments
for firms with substitutive versus complementary strategies, and the concentration of such changes
among dominant firms. Therefore, a plausible alternative story would need to be quite complex.
Nonetheless, my findings are subject to an important caveat that they may reflect changes in
investments net of the effects of the regulation through these alternative channels.
7
The central contribution of my study is to show that financial reporting allows firms to make
strategic gains through investments. A growing literature in accounting investigates the
relationship between firmsβ strategic disclosures and the dynamics of competition.5 This paper
expands this literature and examines how mandatory disclosures affect firmsβ strategic real
decisions. One of the few papers that study this relationship is by Bloomfield (2019), who finds
that large firms with complementary strategies adopt revenue-based CEO pay packages to commit
to aggressive behavior after a mandatory increase in executive pay disclosures. I provide related
evidence on a different commitment mechanism under which financial reporting affects
competition: strategic investments.
This study also contributes to the investment literature by examining a type of investment
disclosure overlooked in the literature: off-balance sheet purchase obligations. Purchase
obligations reflect wide-ranging future strategies, as they include future expenditures not only for
CAPEX and R&D but also for inventory purchases and advertising. This paper highlights the
economic significance of purchase obligations and their strategic uses.
Finally, my findings have important implications for regulators. The primary objective of the
regulation was to provide investors with information about firmsβ obligations from off-balance
sheet arrangements. Although they do not speak to the net effect of the regulation, my finding that
firms use the strategic effect of disclosures about their investments to their advantage sheds light
on a potential unintended effect of the regulation and an unexplored role of financial reporting.
The remainder of the paper proceeds as follows: Section 2 discusses the regulatory
background of purchase obligation disclosures. Section 3 develops hypotheses, and Section 4
describes my sample and data. Section 5 reports my empirical results, and Section 6 concludes.

2. Setting: Disclosure of Purchase Obligations
In response to the Sarbanes-Oxley Act of 2002, the SEC adopted in April 2003 amendments
to the Securities Exchange Act of 1934 to require audited disclosure of off-balance sheet
arrangements. The regulation was implemented to primarily provide investors with contextual
information to assess firmsβ short- and long-term liquidity and capital resource needs and demands,
after the failures of giant firms such as Enron and Winstar following their accounting scandals.6
This regulation has the following two components, which are enforced sequentially over a six-
month period.
The first is that it requires SEC-registered firms, except for small business owners, to provide
an explanation of their contractual off-balance sheet arrangements in the Management's Discussion
and Analysis (MD&A) section of their 10-Ks for their fiscal years ending on or after June 15,
2003.7, 8 Firms need to disclose the material facts and circumstances that provide investors with a
clear understanding of firmsβ off-balance sheet arrangements and their material effects on changes
in financial condition, revenues and expenses, results of operations, liquidity, capital expenditures,
and capital resources.
A second key feature of the regulation is requiring a detailed tabular disclosure of contractual
obligations in the MD&A section of 10-Ks for the fiscal years ending on or after December 15,
2003. Firms need to provide, in a single location in the MD&A section, tabular information about
future payments by specified category of contractual obligations (i.e., long-term debt obligations,
6 The complete text of this regulation βSEC Final Rule: Disclosure in Managementβs Discussion and Analysis about Off-Balance Sheet Arrangements and Aggregate Contractual Obligationsβ (Release No. 33-8182) is available at https://www.sec.gov/rules/final/33-8182.htm 7 βSmall business issuerβ is defined as any entity that (1) has revenues of less than $25,000,000; (2) is a U.S. or Canadian issuer; (3) is not an investment company; and (4) if a majority-owned subsidiary, has a parent corporation that also is a small business issuer. An entity is not a small business issuer, however, if it has a public float (the aggregate market value of the outstanding equity securities held by non-affiliates) of $25,000,000 or more. 8 The regulation also requires these explanations in 10-Qs if there exist material changes outside their ordinary course of business. Therefore, most firms are expected to not report updates on their off-balance sheet arrangements or simply include a reference to their latest 10-Ks. My own examination of numerous 10-Qs is consistent with this.

capital lease arrangements, operating lease arrangements, purchase obligations, and other long-
term liabilities reflected on the balance sheet) and by due date (e.g., less than one year, one to three
years, three to five years, and more than five years). The SEC provides a format that a firmβs table
should substantially conform to, which is shown in Appendix B. Appendix B also contains actual
tabular disclosures made by a few sample firms after the regulation.9
Before this regulation, firms were already required to aggregate and disclose their contractual
payment obligations for debt and for capital or operating leases (see FASB SFAS No. 13,
Accounting for Leases (Nov. 1976); SFAS No. 47, Disclosure of Long-Term Obligations (March
1981)). This regulation additionally requires disclosures of purchase obligations as of the latest
fiscal year-end date. Purchase obligations are defined as agreements to purchase goods or services
that are enforceable and legally binding on the firm. These unconditionally binding definitive
agreements, subject only to customary closing conditions, specify all significant terms, including:
fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions; and
the approximate timing of the transaction.10 They include a broad range of arrangements, including
inventory purchases, CAPEX, R&D, royalty/licensing, advertising/marketing, and strategic
alliances.
This forward-looking information related to firmsβ inputs for production and sales is not
available in firms' financial statements, because executory contractsβwhere both parties to the
contract have not yet performed their dutiesβare not recorded on firmsβ balance sheets. Moreover,
9 The regulation allows a firm βto disaggregate the specified categories by using other categories suitable to its business, but the table must include all of the obligations that fall within specified categories. In addition, the table should be accompanied by footnotes necessary to describe material contractual provisions or other material information to the extent necessary for an understanding of the timing and amount of the contractual obligations in the table.β 10 If the purchase obligations are subject to variable price provisions, then the firm must provide estimates of the payments due and include footnotes about payments that are subject to market risk. In addition, the footnotes should discuss any material termination or renewal provisions to the extent necessary for an understanding of the timing and amount of the firmβs payments under its purchase obligations.
10
prior to the regulation, if firms requested confidential treatment of their material contracts and
redacted their contracts, this forward-looking information was not available to outsiders.
Although they are off-balance sheet expenses, the amounts of purchase obligations reported
are economically significant. Using disclosures of purchase obligations made in fiscal year 2007
and applying an annual discount rate of 5%, Lee (2010) reports that the average value is 9.3% of
total assets for non-financial firms including those not reporting purchase obligations. Furthermore,
he shows that disclosures of purchase obligations after the regulation provide useful information
to investors, because growth in purchase obligations is associated with higher future sales and
earnings. In my online appendix, I document a greater reduction in analystsβ dispersion for firms
with a greater exposure to the regulation (i.e., firms that redacted more contracts before the
regulation), which suggests that the regulation increased the information set of outsiders about
firmsβ future operations.
Firms typically need to enter into purchase obligations well in advance, in time for future
production and/or sales, and these purchase obligations reflect minimum or legally binding (e.g.,
non-cancellable) amounts that are audited. Therefore, disclosures of purchase obligations are likely
to credibly and effectively signal a commitment to future product market strategies. I use this
regulation to study strategic changes in firmsβ investments, because it increases the information
about firmsβ future strategies that is observable to competitors.
11
3. Hypotheses
Due to their irreversible and time-bound nature, investments signal credible commitments to
future strategies that subsequently alter competitorsβ decisions (von Stackelberg 1934; Schelling
1960; Spence 1977; Dixit 1980). For example, increased purchases of inventory or R&D signal
more aggressive future strategies (e.g., greater quantity, lower price, or higher quality), and the
opposite signal less aggressive strategies. These signals affect competitorsβ decisions on future
strategies, because competitors deem those as credible commitments. Therefore, in a dynamic
setting, investments not only have an internal profit-increasing value, but also have an important
strategic value.
My first set of hypotheses examines whether reporting of purchase obligations increases the
extent to which firms strategically change their investments to affect competitorsβ behavior. When
more information about firmsβ investments becomes observable to their competitors, firms will
adjust their investments to exploit their increased strategic value. Therefore, reporting of purchase
obligations should increase the extent to which firmsβ investment decisions are influenced by
strategic motives. I develop specific predictions on firmsβ investment choices based on classical
theory of strategic investments (Fudenberg and Tirole 1984; Bulow et al. 1985).11
Theory on strategic investments classifies firmsβ competition into two typesβcompetition
with strategic substitutes and competition with strategic complements. This classification applies
to firms that produce imperfectly or perfectly substitutive products and hence horizontally compete
for profits. If a firmβs more aggressive strategy (e.g., greater quantity, lower price, higher quality)
11 I rely on theory on strategic investments for entry accommodation (equivalent to incumbent competition). There exists related, but distinct, theory on strategic investments for entry deterrence (e.g., Spence 1977, 1979; Dixit 1979; Smiley 1988; Ellison and Ellison 2011; Cookson 2017, 2018). Based on this theory, recent papers by Bloomfield and Tuijin (2019) and Glaeser and Landsman (2019) empirically show that firms facing a threat of entry increase voluntary disclosure of greater investments to deter the entry of competitors. To help the reader understand the underlying theory for entry deterrence versus entry accommodation as well as the notions of overinvestment versus underinvestment, I discuss theory on strategic investments introduced by Tirole (1988) in my online appendix.
12
decreases competitorsβ marginal profits, then it has competition with strategic substitutes (e.g.,
Cournot competition). If it increases competitorsβ marginal profits, then it has competition with
strategic complements (e.g., Bertrand competition).12
According to theory, firms desire to commit to actions that induce their competitors to take
less aggressive product market strategies, because this increases their expected future profits (e.g.,
Bulow et al. 1985; Sundaram et al. 1996). However, the action they need to take to induce such
strategies is contingent on how they expect their moves will affect their competitorsβ marginal
profits or, equivalently, on whether they have strategic substitutes or complements with their
competitors. If they face competition with strategic substitutes, then firms will increase their
investments to signal that they will use aggressive product market strategies in the future (e.g.,
greater quantity, lower price, higher quality). This is because doing so reduces competitorsβ
marginal profits and induces them to adopt less aggressive strategies in response. On the other
hand, if firms face competition with strategic complements, then they will reduce their investments.
This is because doing so reduces competitorsβ marginal profits and induces them to match firmsβ
less aggressive strategies.13
I expect to find a change in investments only among dominant firms with large market share
which have the βfirst-moverβ advantage. They can exert a significant influence on the quantity and
price of products in the industry, and hence the actions of other firms, while small firms cannot
(e.g., Gisser 1984, 1986; Lieberman and Montgomery 1988; Gourio and Rudanko 2014; Aobdia
and Cheng 2018; Bloomfield 2019). For example, dominant firms likely have advantages in capital
(e.g., liquidity, fixed assets, technology) and costs (e.g., economies of scale, bargaining power,
12 By construction, an increase in a firmβs aggressiveness reduces its competitorsβ profits. The difference between strategic substitutes and complements is its effect on competitorsβ marginal profits with respect to their aggressiveness. See Appendix C for further discussion of competition with strategic substitutes versus complements. 13 This prediction is based on the assumption that an increase in a firmβs investments, on average, raises its competitorsβ expected aggressiveness of the firm and a decrease in a firmβs investments lowers it.
13
customer loyalty) that give them enough flexibility to substantially increase or decrease
investments. Therefore, I predict that dominant firms whose investment choices are more revealed
by the regulation increase their investments if they have substitutive strategies with competitors,
and reduce them if they have complementary ones. This leads to my first set of hypotheses, H1a
and H1b:
H1a: In competition with substitutive strategies, dominant firms with an increase in
disclosures about investments raise their investments after the regulation.
H1b: In competition with complementary strategies, dominant firms with an increase in
disclosures about investments reduce their investments after the regulation.
My next hypothesis examines the responses of non-dominant firms to their dominant
competitorsβ strategic investments. Theory predicts that firmsβ commitments signaled by
investments affect competitorsβ decisions about their future actions (e.g., von Stackelberg 1934;
Fudenberg and Tirole 1984).14 Therefore, non-dominant firms are expected to choose their optimal
product market strategies conditional on their dominant competitorsβ strategies signaled through
their investments.
Specifically, after dominant firms change their investments to signal their future product
market strategies, non-dominant firms will re-optimize their product market decisions based on
their new marginal profitability. The direction of this readjustment depends on whether their new
marginal profitability is decreased or increased. Because dominant firmsβ strategies signaled by
their strategic investments reduce their marginal profits in both types of competition, I expect non-
dominant firms to optimally reduce their aggressiveness. Furthermore, because investments
foreshadow product market strategies due to their irreversible and time-bound nature, reductions
14 For example, in industries with quantity competition, competitors may interpret the firmβs purchase of inventory as bad news about their profitability and may reduce their quantity. This is because purchase of large inventory, which is costly to remove if it goes unsold, credibly signals a plan to produce and sell a large quantity.
14
in the aggressiveness of non-dominant firmsβ strategies will be first manifested as lower
investments. This leads to the following hypothesis, H2:
H2: In both types of competition, non-dominant firms reduce investments after the regulation.
Results consistent with these hypotheses would suggest that reporting of future investments
makes dominant firms engage more in strategic investments and subsequently makes non-
dominant firms adopt less aggressive product market strategies.
4. Sample & Data
To construct my sample, I start with the universe of firms at the intersection of Compustat and
CRSP. I then discard utility (SIC codes 4900β4949) and financial (SIC codes 6000β6999) firms,
which are highly regulated, and drop small business companies, which are exempt from the
regulation. Excluding firm-years that end between the first and second effective dates of the
regulation (i.e., June 15, 2003 and December 15, 2003, respectively), I use 5 years before and after
the regulationβa 10-year window surrounding the regulationβto examine its impact on strategic
investments.15 Furthermore, to mitigate the possibility that changes in sample composition affect
the results, I only keep firms with at least one year of data in each of the pre- and post-regulation
periods.
Due to data availability of text-based SEC filings from the EDGAR website and Hoberg and
Phillipsβ similarity score, as well as an additional sample restriction of having at least one
investment contract prior to the regulation (discussed below in section 4.1), my main sample
consists of 14,712 firm-years representing 1,890 firms spanning from 1998 through 2008. Below,
I discuss in detail how I obtain the data used in my analyses.
15 I use 5 years after the regulation to allow for changes in off-balance sheet purchase obligations to manifest in investments recognized in financial statements. I find that the average and median durations of purchase obligations reported are 3.2 and 3.3 years, respectively.
15
4.1. Data on Pre-regulation Redaction of Contracts Related to Investments
I collect data on investment contracts by conducting a textual analysis on all material contracts
that are filed as exhibits to 10-K/Q and 8-K required by Item 601 of Regulation S-K. Using Python,
I first extract all material contracts filed during the 5 years prior to the regulation using the string
β<TYPE>EX-10β which the EDGAR system adds to the top of every contract for identification
purposes (Li 2013). I then identify investment contracts by counting the number of words related
to investments. By building a search string based on prior papers, such as Merkley (2014) and
Costello (2013), I ensure that I build a sufficiently comprehensive set of search terms to find
contracts related to investment activity.
The words or portions of words I use to capture firmsβ investments are the following: advertis,
aircraft, build, built, buy, bought, capacity, capacities, CAPEX, clinical, collaborat, construct,
consumer, customer, deliver, develop, distribut, drug, engineer, equipment, estate, exclusive,
expand, expansion, expenditure, facility, facilities, factory, factories, fuel, hardware, infrastructure,
innovate, invent, invest, joint venture, land, license, licensing, manufactur, marketing, material,
merchandis, operat, outsource, patent, plant, procure, product, project, property, properties,
purchas, research, R&D, right, royalt, science, scientist, sell, software, sold, sponsor, store, storage,
supply, supplie, technology, transportation, truck, vehicle, and warehouse. 16
I categorize a contract to be related to investments if it contains at least 5 unique words in the
set of search terms for investments. Furthermore, to ensure that I capture the extent of a firmβs
investment outsourcing, instead of investment insourcing, I drop any contract that includes at least
one term from βacquireβ, βacquisitionβ, βmergeβ, and βM&Aβ even if it includes at least 5 unique
words related to investments. I also drop contracts that include at least one term related to
16 I do not include words related to operating or capital leases, despite them relating to investments, because disclosures about future lease obligations were required in a footnote before the regulation (FASB SFAS No. 13 and SFAS NO. 47).
16
employee compensation and debt or shareholder contracts even if it includes at least 5 unique
words related to investments.17 These additional steps further increase the accuracy of my ex ante
βtreatmentβ as a proxy for a firmβs exposure to the regulation. Additionally, to address the concern
that firms with contractual investments could be fundamentally different from those without, I
exclude firms from all my analyses that have no investment contracts during the 5-year pre-
regulation period.
Next, among the contracts categorized as investment contracts, I identify those that are
redacted. By Rule 406 and Rule 24b-2, portions of material contracts can be redacted if they are
deemed by the SEC to cause competitive harm to the filing firm. A redacted copy of the material
contract should still be filed as an exhibit to 10-K/Q and 8-K, and I identify redacted contracts by
taking an approach similar to those of Verrecchia and Weber (2006), Boone et al. (2016), Glaeser
(2018), and Bourveau et al. (2019). Specifically, I use Python to search contracts for the following
phrases: βconfidential treatmentβ, βconfidential requestβ, βredactβ, βCT Orderβ, βFreedom of
Information Actβ, βFOIAβ, βRule 406β, βRule 24b-2β, βconfidentialβ¦redact/omit/deleteβ¦β,
βredact/omit/deleteβ¦confidentialβ¦β, βintentionβ¦ redact/omit/deleteβ¦β, and
βredact/omit/deleteβ¦intention...β18 I classify an investment contract as a redacted one, if it contains
any of these phrases.
4.2. Tabular Data on Off-Balance Sheet Purchase Obligations
I use a Python code to collect the purchase obligation data for 5 years after the regulation. In
addition to using the terms like purchase obligation(s), firms use various labels to report their
17 The keywords used are as follows: bonus plan/agreement, compensation plan/agreement, employment plan/agreement, incentive plan/agreement, stock award/incentive/option, severance, pension plan/agreement, retirement benefit/plan/agreement, savings plan, loan (modification) plan/agreement, debenture, promissory note, credit agreement/facility, stock/share (re)purchase, shareholder agreement, shareholdersβ agreement, and shareholder agreement. 18 According to Heinle et al. (2018), one could use confidential treatment (CT) order forms to identify redacted contracts. However, this information is only available on EDGAR from 2009.
17
future contractual investments, including βsupply contractβ, βexclusive license agreementβ,
βproduction-related obligationβ, βcommercial commitmentsβ, etc. Therefore, I first read
approximately two hundred 10-Ks to create the following list of words or portions of words that
firms use to indicate purchase obligations: advertis, agreement, aircraft, alliance, build, buy,
capacit, capex, capital, clinical, collaborat, commitment, commercial, connectivity, construct,
consult, consumer, customer, deliver, develop, distribut, drug, employment, energy, engineer,
equipment, estate, exclusiv, expand, expansion, expenditure, facility, facilities, factory, factories,
fuel, gas, hardware, infrastructur, innovat, intellectual, invent, invest, joint venture, land, license,
licensing, manufactur, marketing, material, merchandis, methane, obligation, oil, operat, outsourc,
patent, plant, procure, product, program, project, promot, property, properties, purchas, research,
R&D, right, royalt, science, scientist, sell, software, sponsor, storage, store, supplie, supply, take-
or-pay, technology, transmission, transportation, truck, utilities, utility, vehicle, ventures, and
vessel.
Then, I scrape the relevant data related to firmsβ purchase obligations from 10-Ks downloaded
from the EDGAR website, including the unit used (e.g., thousands, millions) and the amounts due
each period (e.g., less than one year, one to three years, three to five years, more than five years).
To ensure that I only scrape data on purchase obligations, not other types of long-term liabilities
(e.g., long-term debt, operating/capital leases, employee benefits), I drop the data whenever its
label includes one of the following words: borrowing, benefit, credit, debt, debenture, deposit,
equity, financing, interest, lease, loan, minority, note, pension, and tax.
4.3. Data on Types of Competition
To find out whether a firm faces competition with strategic substitutes or complements, I first
need to identify its competitors that have the same targeted customers. Therefore, I define as
competitors the 5 nearest firms identified by Hoberg and Phillips (2010, 2016)β firm-by-firm
18
pairwise similarity score in the year prior to the regulation.19 I obtain this data from the Hoberg-
Phillips Data Library. Hoberg and Phillipsβ score is based on the similarity of two firmsβ final
products, not production processes (which some of the more traditional industry classifications do),
and is purged of vertical relationships. These features make their measure better at identifying a
small set of direct competitors than traditional industry classifications, such as SIC, NAICS, and
Fama-French industry classifications, which tend to be more crude.20
Having identified a firmβs direct competitors, following Bloomfield (2019), I use a measure
developed by Kedia (2006) to classify the firmβs competition type using the 5-year quarterly data
on sales and net income prior to the regulation. The distinction of strategic substitutes versus
complements is determined by whether more aggressive strategies (e.g., greater quantity, lower
price, higher quality) by competitors decrease or increase a firmβs marginal profitability (Bulow
et al. 1985). Kediaβs measure is designed to directly estimate this change in marginal profitability
by empirically measuring the slope of a firmβs reaction function (i.e., cross partial derivative of a
firmβs net income with respect to the firmβs own sales and its competitorsβ sales). If the value of
the measure is negative, then the firm faces competition with strategic substitutes. If the value of
the measure is positive, then the firm faces competition with strategic complements.
By using firmsβ quarterly data on sales and net income during the 5 years before the regulation,
I assume that firmsβ competition types do not vary from the pre- to post-regulation period as is
commonly done in the literature (e.g., Sundaram et al. 1996; Bloomfield 2019). This assumption
is reasonable because firmsβ competition types are determined by their demand functions (e.g.,
elasticity) and cost functions (e.g., decreasing marginal cost), which are unlikely to change much
19 My results are robust to using 10 nearest firms, although they become slightly weaker. 20 Hoberg and Phillips (2010, 2016) show that their measure outperforms SIC and NAICS in explaining firm-specific characteristics, such as profitability, Tobinβs Q, and dividends. Their measure is based on web-crawling and text-parsing algorithms that process the text in the business descriptions of 10-K annual filings on the EDGAR website.
19
during a short time window around the 2003 regulation. See Appendix C for underlying theory for
strategic substitutes and complements as well as discussion of Kediaβs empirical proxy.
Although it is considered a state-of-art measure for competition type, Kedia (2006)βs measure
is subject to errors as it uses ex post data on sales and profits to capture firmsβ ex ante incentives.
Therefore, in a robustness test, I use the three measures alternative to Kedia (2006) used by
Bloomfield (2019). The results from using the two measures based on production flexibility and
R&D spending, respectively, are in Table 8. The results from using mining firms are tabulated in
the online appendix.
5. Findings
5.1. Descriptive Statistics
Panel A of Table 1 presents descriptive statistics for the key variables used in my main tests.
In the 5-year pre-regulation period, firms on average have 0.7 investment contract per year and
redact 0.12 investment contract per year. I find that 16.6% (=313/1890) of firms have at least one
redacted investment contract during pre-regulation years. These statistics are similar to what prior
literature documents. For example, Heinle et al. (2018) find the average annual redacted
disclosures of 0.13. Also, Verrecchia and Weber (2006) and Glaeser (2018) report that about 16-
17% of firms redact their material contracts. The average amount of total investments reflected on
firmsβ financial statementsβwhich include inventory purchases, CAPEX minus sale of PP&E,
R&D, and advertising expensesβis approximately 100% of lagged total assets. As expected, the
majority of these investments are inventory purchases, which constitute about 84% of lagged total
assets on average.
Panel B of Table 1 reports descriptive statistics of purchase obligations required by the
regulation, which are primarily used in my validation tests. In the post-regulation period,
20
approximately 69% of my sample firm-years report purchase obligations in their 10-Ks, and the
average amount of purchase obligations is 25% of total assets.21 If I restrict my sample to those
reporting purchase obligations, the amount of total purchase obligations is large, with an average
of $703 million (or 51% of total assets) and a median of $29 million (or 9% of total assets). These
suggest that firmsβ use of purchase obligations is economically meaningful, although right-skewed.
Moreover, off-balance sheet purchase obligations are economically large, even compared to
total investments reflected in firmsβ financial statements. The average and median amounts due
within one year are 29-30% and 5-7% of annual total investments, respectively. The average and
median durations are 3.2 and 3.3 years, respectively. Moreover, the average and median durations
weighted by the amount due each period are 2 and 1.7 years, respectively. Figure 1 plots the
distribution of purchase obligations by each due date. The figure indicates that the majority of the
total payment is due within the first two years. For example, on average, 59% of total purchase
obligations are due within one year after the reporting date.22
In the rest of Panel B of Table 1, I show descriptive statistics of purchase obligations by type.
Taking advantage of the labels firms use to report purchase obligations in their 10-Ks, I categorize
purchase obligations into four types: inventory purchases, CAPEX, R&D, and advertising
expenses.23 While all these four types are informative about firmsβ future strategies, they represent
investments into different assets (e.g., inventory, PP&E, intangibles). I find that inventory
purchases are the most economically significant, with the average amount of 56% of total assets
21 By summing payment obligations across years, I effectively assume a zero discount rate. 22 To compute the duration of purchase obligations, I assume a duration of 1 year for payments due within 1 year, 2 years for payments due in 1-3 years, 4 years for payments due in 3-5 years, and 5 years for payments due after 5 years. 23 The words used to identify inventory purchases include deliver, inventory, manufacture, merchandise, supplies, etc. Those used to identify CAPEX include capex, capacity, capital expenditure, equipment, facility, plant, etc. Those used to identify R&D include alliance, clinical, collaboration, develop, innovation, license, patent, R&D, research, joint venture, royalty, etc. Those used to identify advertising expenses include advertising, marketing, promotion, sponsor, etc. I categorize a purchase obligation as multiple categories, if its label contains more than one keyword for different categories.
21
(or $730 million) for firms reporting inventory purchases as purchase obligations and 5.7% of total
assets for all reporting and non-reporting firms. This suggests that purchase obligations differ
significantly from traditional investments considered in prior literature, which tends to focus just
on CAPEX or R&D.
Panel A of Figure 2 provides similar information graphically, indicating that inventory
purchases are the most frequent and largest type of purchase obligations, followed by R&D,
CAPEX, and advertising expenses. This order of magnitudes is the same as the order of magnitudes
among the four corresponding financial statement items (see Panel A of Table 1). This is consistent
with purchase obligations foreshadowing future investments to be recognized in financial
statements. Panel B of Figure 2 illustrates economic magnitudes of the four types of purchase
obligations, conditioned on reporting each corresponding type. It shows that all four types have
large magnitudes on average when I restrict my sample to reporting firms. For example, although
only 9% of purchase obligations correspond to advertising expenses (Panel A of Figure 2), the
average and median amounts reported are 65% and 3% of total assets, respectively, for those
reporting advertising expenses as purchase obligations (Panel B of Figure 2).
Altogether, the descriptive statistics provided in Table 1, Figure 1, and Figure 2 suggest that
purchase obligations disclosed in a given year are likely to be an informative signal about firmsβ
investments (i.e., expenditures for operations, fixed assets, and innovations) and hence about their
product market strategies in the near future. This is consistent with the findings of Lee (2010), who
shows that growth in purchase obligations is associated with higher future sales and earnings.
5.2. Tests on Investments (H1a, H1b, and H2)
My main tests examine whether dominant firms affected by the 2003 regulation strategically
change their investments (H1a and H1b). Because not all firms are affected by the regulation to
the same degree, I investigate whether dominant firms whose investment choices are more
22
revealed by the regulation increase their investments by a greater amount if they have substitutive
strategies with competitors, and reduce by a greater amount if complementary. I run the following
difference-in-differences regression model separately for dominant firms with strategic substitutes
and those with strategic complements:
ππππππππππ πΌπΌπΌπΌπΌπΌπΌπΌπΌπΌπππΌπΌπΌπΌπΌπΌπππΌπΌππ,π‘π‘
= πΌπΌ1πππππΌπΌπππ‘π‘ Γ πππππΌπΌπππΌπΌπππππΌπΌπππππππππππππΌπΌππ + οΏ½π½π½πΆπΆπππΌπΌπππππππππΌπΌππ,π‘π‘
+ οΏ½π½π½πππππΌπΌπππ‘π‘ Γ πΆπΆπππΌπΌπππππππππΌπΌππ,π‘π‘ + πΏπΏπππππΌπΌπππ‘π‘(ππππ πππ‘π‘ ππππ ππππππππ Γ πππ‘π‘) + πΎπΎππ + ππππ,π‘π‘, (1)
where the dependent variable captures the amount of investments recognized in financial
statements (i.e., balance sheet, income statement, and cash flow statement). The key independent
variable PreRegRedaction is the annual average number of redacted investment contracts in pre-
regulation years, which serves as an ex ante βtreatmentβ measure. Post is an indicator variable that
takes the value of one for post-regulation years. πππ‘π‘, ππππππππ Γ πππ‘π‘, and πΎπΎππ are year, industry by year,
and firm fixed effects, respectively. For control variables, I follow prior research on investments
(e.g., Durnev and Mangen 2009; Badertscher et al. 2013; Beatty et al. 2013; Kausar et al. 2016). I
include return on assets, book to market (BTM), market value of equity, leverage, losses indicator,
illiquidity, volatility, size-adjusted return, institutional ownership, Tobinβs Q, sales growth, cash
flows from operations (CFO), cash and cash equivalents, and asset tangibility.24
I measure the dependent variable as the sum of inventory purchases, R&D expenditure,
CAPEX, and advertising expenditure less cash receipts from sale of PP&E multiplied by 100 and
scaled by lagged total assets, following Biddle et al. (2009). I do not scale investments by sales,
because strategic investments can lead to changes in sales (see Table 6). Also, I do not include
acquisition costs because their disclosure is not affected by the regulation.
24 See Appendix A for variable definitions.
23
To classify firms into competition with strategic substitutes versus complements, I use a proxy
constructed by Kedia (2006) using pre-regulation quarterly sales and net income data for firms and
their 5 closest competitors identified by Hoberg and Phillips (2010, 2016) (see Section 4.3 for
details). I categorize a firm as a dominant firm if its market share is above the median of its
competition group, consisting of the firm itself and its 5 nearest competitors, and a non-dominant
firm if its market share is equal to or below the median.
Table 2 reports results consistent with my hypotheses (H1a and H1b). In particular, I find that
dominant firms with a greater increase in investment observability (i.e., a greater degree of
βtreatmentβ) increase their investments by a greater amount if they have substitutive strategies
with competitors, and reduce them by a greater amount if they have complementary strategies. The
coefficient of 25.609 in Column (3) of Table 2 suggests that a one-standard-deviation increase in
pre-regulation redacted investment contracts leads to a 5.1% (=25.609β¨―0.2/100) increase in
investments for a dominant firm with the average value of investments in competition with
strategic substitutes.25 Similarly, the coefficient of β24.734 in Column (6) suggests that a one-
standard-deviation increase in pre-regulation redacted investment contracts leads to a 4.9% (=β
24.734β¨―0.2/100) reduction in investments for an average dominant firm with strategic
complements. According to theory on strategic investments, this two-way finding is consistent
with firms strategically changing investments in directions that reduce the marginal profitability
of competitors and thus induce less aggressive strategies from them.
25 I find results of similar economic magnitudes when I use log-transformed variables. For example, when I use the log of investments and the log of one plus pre-regulation average redacted investment contracts as the dependent variable and the key independent variable, respectively, I find that an increase of approximately 0.2 in pre-regulation average redacted investment contracts (or an 18% increase in one plus pre-regulation average) results in approximately a 6.2% increase in investments for an average firm with strategic substitutes and a 5.1% reduction for an average firm with strategic complements. To facilitate interpretations of results, I report results using variables without log transformations.
24
These results are especially intuitive if we view firms with strategic substitutes as competing
in quantity, and firms with strategic complements as competing in price or quality, which is a
common approach in the literature (e.g., Gal-or 1986; Darrough 1993).26 My findings then suggest
that dominant firms competing in quantity increase their investments to signal a larger quantity, as
it will reduce the market-clearing prices of competitorsβ products and induce them to reduce their
quantities. In contrast, dominant firms competing in price or quality reduce their investments to
signal less aggressive pricing or quality strategies, as it will induce competitors to similarly engage
in less aggressive behavior.
In Figure 3, I show that the trend lines for investments between dominant firms affected (i.e.,
βtreatedβ firms) and unaffected (i.e., βcontrolβ firms) by the regulation decouple after the
regulation for both types of competition, while showing parallel trends prior to the regulation. The
figure plots the coefficients on Year⨯ PreRegRedaction for years surrounding the regulation date
and their 90% confidence intervals. The notation Year+1 denotes the first firm-year after the
regulation date, Year+2 denotes the second firm-year, and so on. I exclude 4 and 5 years before
the regulation (i.e., Year-5 and Year-4) to find the average difference in investments between
firms affected and unaffected by the regulation in the absence of the regulation.27 Therefore, the
coefficients on the interaction terms measure the change in investments relative to the baseline
years Year-5 and Year-4. The coefficients become significant in the year following the regulation,
suggesting that βtreatedβ firms and βcontrolβ firms display strong similarities in investments
leading up to the regulation. After the regulation date, βtreatedβ firms engage in significantly
higher investments in competition with strategic substitutes and lower in competition with strategic
complements.
26 This categorization is always true when demand is linear and marginal cost is constant. 27 In all tests, I exclude firm-years that end between the two effective dates of the regulation (i.e., June 15, 2003 and December 15, 2003, respectively).
25
I supplement my main tests with tests on different components of investments. Specifically, I
estimate the regression model (1), after replacing the dependent variable with investments for
capacity and for product differentiation. These tests are motivated by the idea that competition
with strategic substitutes has greater physical capacity (e.g., Kreps and Scheinkman 1983; Maggi
1996), and competition with strategic complements has a greater degree of product differentiation
or customer loyalty (e.g., Chamberlin 1933; Lancaster 1966; Schmalensee 1982; Singh and Vives
1984). These characteristics suggest that investments in capacity likely have a greater strategic
value in competition with strategic substitutes, and investments in product differentiation have a
greater strategic value in competition with strategic complements.
I use the sum of inventory purchases and CAPEX less cash receipts from sale of PP&E as
investments in capacity, and the sum of R&D and advertising expenses as investments in product
differentiation. The results of tests on these two types of investments are shown in Table 3. Table
3 shows that, after an increase in the observability of investments, dominant firms with strategic
substitutes primarily increase investments in capacity, and those with strategic complements
primarily reduce investments in product differentiation. These results provide additional assurance
that changes in investments are driven by strategic motives. 28 Moreover, these results are
consistent with firms with strategic substitutes primarily competing in quantity and those with
strategic complements primarily competing in quality. If R&D expenses are considered to be
reducing production costs rather than increasing product differentiation, the result for firms with
strategic complements is consistent with them primarily competing in price.
28 Further tests show that results in competition with strategic substitutes concentrate in inventory purchases and results in competition with strategic complements concentrate in R&D (untabulated). This is consistent with the 2003 regulation primarily increasing disclosures of firmsβ future investments in inventory purchases and R&D (see Panel B of Table 1).
26
I report in Table 4 the results of falsification tests where I use acquisition costs or off-balance
sheet future operating lease expenses as the dependent variable in model (1). Although these two
investment items are informative about future strategies, their disclosures were required even
before 2003. By SFAS No. 13, disclosures about future operating leases were required in a 10-K
footnote before the regulation. Also, disclosures about acquisitions were required, prior to the
regulation, on Form 8-K, Schedule 14A, S-4, etc. I find that no dominant firms change their
acquisition costs or operating lease expenses after the 2003 regulation. 29 This non-result for
investment items whose disclosures are not affected by the regulation adds further confidence to
my findings.30
Next, I investigate whether and how non-dominant firms respond to dominant firmsβ strategic
investments. To test this, I change model (1) such that Post is interacted with the pre-regulation
average number of redacted investment contracts for a firm iβs dominant competitors among the 5
nearest competitors identified by Hoberg and Phillips (2010, 2016) (i.e., average βtreatmentβ of
dominant competitors). This is because non-dominant firmsβ response will be correlated with how
much their dominant competitors are affected by the regulation and therefore are engaging in
strategic investments. The model for testing non-dominant firmsβ response is as follows:
ππππππππππ πΌπΌπΌπΌπΌπΌπΌπΌπΌπΌπππΌπΌπΌπΌπΌπΌπππΌπΌππ,π‘π‘
= πΌπΌ1πππππΌπΌπππ‘π‘ Γ πππππΌπΌπππΌπΌπππππΌπΌπππππππππππππΌπΌβππ + οΏ½π½π½πΆπΆπππΌπΌπππππππππΌπΌππ,π‘π‘
+ οΏ½π½π½πππππΌπΌπππ‘π‘ Γ πΆπΆπππΌπΌπππππππππΌπΌππ,π‘π‘ + ππππππππ Γ πππ‘π‘ + πΎπΎππ + ππππ,π‘π‘. (2)
I predict πΌπΌ1<0 for non-dominant firms across both types of competition (H2) for the following
reasons. In competition with strategic substitutes, it is optimal for non-dominant firms to reduce
29 I measure off-balance sheet operating lease expenses as the sum of all future operating expenses. The results are robust to including the current operating lease expense recognized in income statements. 30 The results on operating lease expenses are robust to scaling by lagged PP&E, not lagged total assets.
27
the aggressiveness of strategies when dominant competitors signal more aggressive strategies
through increased investments, because competitorsβ aggressive strategies reduce their marginal
profitability. Similarly, in competition with strategic complements, it is optimal to reduce
aggressiveness when dominant competitors signal less aggressive strategies through reduced
investments, because competitorsβ less aggressive strategies reduce their marginal profitability.
Non-dominant firmsβ less aggressive strategies will manifest as lower investments, because
investments are indicative of firmsβ future product market strategies.
The results in Panel A of Table 5 are consistent with my prediction for H2. The coefficients
of β48.397 and β58.036 in Columns (1) and (2), respectively, suggest that a one-standard-deviation
increase in a dominant competitorβs pre-regulation redacted investment contracts reduces an
average non-dominant firmβs investments by 3.2% (=β48.397β¨―(0.2/3)/100) in competition with
strategic substitutes and by 3.9% (=β58.036β¨―(0.2/3)/100) in competition with strategic
complements. These suggest that non-dominant firms respond optimally to dominant firmsβ
signaling of future strategies that reduce their marginal profits.
Again, if we view firms with strategic substitutes as competing in quantity, and firms with
strategic complements as competing in price or quality, these results for non-dominant firms are
very intuitive. In quantity competition, when dominant firms increase their investments to signal
a larger quantity, it is optimal for non-dominant firms to reduce their investments in quantity and
avoid a further reduction in the market-clearing prices of their products. In price or quality
competition, when dominant firms reduce their investments to signal less aggressive pricing or
quality strategies, it is optimal for non-dominant firms to also reduce their investments in lowering
price or improving quality and benefit from greater profit margins.
Furthermore, as falsification tests, I show in Panel B of Table 5 that non-dominant firmsβ
changes in investments are not correlated with increases in the observability of their own
28
investments. This is consistent with non-dominant firms not engaging in strategic investments as
their investments do not have strategic effects (i.e., they do not have a βfirst-moverβ advantage).
In sum, my findings are consistent with H1a, H1b, and H2. I find that dominant firms
strategically change investments after the regulation, which increased the observability of future
investments to competitors and therefore the signaling value of investments. I also find that these
changes in investments induce less aggressive behavior from their non-dominant competitors.
5.3. Implications for Competition
In this section, I test whether dominant firmsβ strategic investments change their own and non-
dominant competitorsβ product market outcomes. I do so by estimating the following two
regression models for dominant firms and non-dominant firms, respectively:
πππππππππππππππππππππππΌπΌπππππππππππππΌπΌπΌπΌππ,π‘π‘
= πΌπΌ1πππππΌπΌπππ‘π‘ Γ πππππΌπΌπππΌπΌπππππΌπΌπππππππππππππΌπΌππ + οΏ½π½π½πΆπΆπππΌπΌπππππππππΌπΌππ,π‘π‘ + οΏ½π½π½πππππΌπΌπππ‘π‘ Γ πΆπΆπππΌπΌπππππππππΌπΌππ,π‘π‘
+ ππππππππ Γ πππ‘π‘ + πΎπΎππ + ππππ,π‘π‘ , (3) πππΌπΌππ
πππππππππππππππππππππππΌπΌπππππππππππππΌπΌπΌπΌππ,π‘π‘
= πΌπΌ1πππππΌπΌπππ‘π‘ Γ πππππΌπΌπππΌπΌπππππΌπΌπππππππππππππΌπΌβππ + οΏ½π½π½πΆπΆπππΌπΌπππππππππΌπΌππ,π‘π‘ + οΏ½π½π½πππππΌπΌπππ‘π‘ Γ πΆπΆπππΌπΌπππππππππΌπΌππ,π‘π‘
+ ππππππππ Γ πππ‘π‘ + πΎπΎππ + ππππ,π‘π‘ . (4)
In these two models, the dependent variable represents various product market outcomes, such
as COGS, sales, and profit margins. Post is an indicator variable that takes the value of one for
post-regulation years. ππππππππ Γ πππ‘π‘ and πΎπΎππ are industry by year and firm fixed effects, respectively.
πππππΌπΌπππΌπΌπππππΌπΌπππππππππππππΌπΌππ in model (3) is the pre-regulation average number of firmsβ own redacted
investment contracts in the 5-year pre-regulation period (i.e., βtreatmentβ), and
πππππΌπΌπππΌπΌπππππΌπΌπππππππππππππΌπΌβππ in model (4) is the pre-regulation average number of redacted investment
29
contracts of dominant competitors identified by Hoberg and Phillips (2010, 2016) (i.e., average
βtreatmentβ of dominant competitors).
I first investigate whether both dominant and non-dominant firmsβ COGS change in the same
direction as their investments. This is to validate that investments are credible commitments. I use
COGS as the dependent variable to capture the aggressiveness of strategies, because a higher value
of COGS is consistent with a larger quantity sold via aggressive product market strategies, and a
lower value of COGS is consistent with a smaller quantity sold. I predict πΌπΌ1 > 0 for dominant
firms with strategic substitutes, πΌπΌ1 < 0 for dominant firms with strategic complements, and πΌπΌ1 <
0 for non-dominant firms across both types of competition.
The results for dominant firms are shown in Columns (1) and (4) of Table 6 Panel A. The
coefficient of 27.533 in Column (1) suggests that a one-standard-deviation increase in pre-
regulation redacted investment contracts results in a 6.6% (=27.533β¨―0.2/83) increase in COGS
over lagged total assets for an average dominant firm with substitutive strategies. Similarly, the
coefficient of β17.653 in Column (4) indicates that a one-standard-deviation increase in pre-
regulation redacted investment contracts results in a 4.3% (=β17.653β¨―0.2/83) reduction in COGS
over lagged total assets for an average dominant firm with complementary strategies. This suggests
that dominant firmsβ signaling of commitments through investments foretells the aggressiveness
of their future strategies (i.e., it is not βcheap talkβ), which is expected, as investments are
irreversible and time-bound.
The results for non-dominant firms are shown in Columns (1) and (4) of Table 6 Panel B. The
results suggest that non-dominant firms adopt less aggressive strategies, consistent with their
reduced investments. The coefficients in Columns (1) and (4) suggest that a one-standard-deviation
increase in one of the dominant competitorsβ pre-regulation redacted investment contracts leads to
a 3.5% (=β42.956β¨―(0.2/3)/83) reduction in COGS over lagged total assets for an average non-
30
dominant firm in competition with strategic substitutes, and a 4.2% (=β52.257β¨―(0.2/3)/83)
reduction for an average non-dominant firm in competition with strategic complements. The
results in COGS for both dominant and non-dominant firms confirm that increases and decreases
in investments indicate increases and decreases in the aggressiveness of product market strategies,
respectively.
As a natural next step, I investigate changes in sales and profit margins as a consequence of
changes in the aggressiveness of product market strategies. I estimate model (3) for dominant firms,
using sales or profit margins as the dependent variable. I similarly estimate model (4) for non-
dominant firms.
When the dependent variable is sales, I predict πΌπΌ1 > 0 for dominant firms and πΌπΌ1 < 0 for
non-dominant firms in competition with strategic substitutes. This is because dominant firms that
adopt more aggressive strategies will take away sales from non-dominant firms that adopt less
aggressive strategies. I do not make predictions about sales for firms with strategic complements,
where both dominant and non-dominant firms adopt less aggressive strategies. This is because an
increase in prices and a reduction in the quantities sold have offsetting effects on sales, making the
net effect ambiguous.
When the dependent variable is profit margins, I predict πΌπΌ1 > 0 for both dominant and non-
dominant firms with strategic complements. This is because they charge higher prices or raise
market-clearing prices by reducing the total quantities sold. I do not make predictions for firms
with strategic substitutes, because an increase in the quantities sold by dominant firms and a
decrease in the quantities sold by non-dominant firms will have offsetting effects on the market-
clearing prices of dominant firmsβ products.
The rest of Table 6 shows results for sales and profit margins. In Column (2) of Panel A, I
find that a one-standard-deviation increase in pre-regulation redacted investments leads to a 5.2%
31
(=31.468Γ0.2/120) increase in sales over lagged total assets for an average dominant firm with
strategic substitutes. In Column (2) of Panel B, I find that a one-standard-deviation increase in one
of the dominant competitorsβ pre-regulation redacted contracts leads to a 1.7% (=β
30.173Γ(0.2/3)/120) reduction in sales over lagged total assets for an average non-dominant firm
with strategic substitutes. These results are consistent with my predictions. In Column (5) of Panel
A and Panel B, I find no significant change in sales for firms with strategic complements. I interpret
this as increases in prices being offset by reductions in quantities, or vice versa.
I also find results consistent with my predictions for profit margins. In Column (6) of Panel
A, I find that a one-standard-deviation increase in pre-regulation redacted investment contracts
raises profit margins of a median dominant firm by 3.7% (=6.506Γ0.2/35) in competition with
strategic complements. Also, in Column (6) of Panel B, I find that a one-standard-deviation
increase in one of the dominant competitorsβ redacted contracts raises profit margins of a median
non-dominant firm by 2.6% (=13.547Γ(0.2/3)/35). I find no significant changes in profit margins
for both dominant and non-dominant firms with strategic substitutes, which suggests that changes
in their sales are primarily driven by changes in their quantities sold, not changes in their selling
prices.
Overall, the results in Table 6 suggest that strategic investments have real effects on firmsβ
product market strategies and competitive dynamics. After the 2003 regulation, dominant firms
with strategic substitutes take away sales from non-dominant firms by increasing investments and
adopting more aggressive strategies. Also, dominant firms with strategic complements induce an
anti-competitive environment by decreasing investments and adopting less aggressive strategies.
These results are consistent with the 2003 regulation giving advantages to dominant firms by
increasing the strategic role of their investments.

5.4. Validation and Robustness Tests
In this section, I run several tests to corroborate my main findings. My first set of tests seeks
to validate my methodology. To estimate the degree of βtreatmentβ by the 2003 regulation, I use
the number of redacted investment contracts before the regulation. My choice of the βtreatmentβ
measure assumes firms that redacted more investment contractsβhence withheld more
information about their contractual investmentsβin the pre-period experience a greater increase
in observability of their investments after the regulation. Additionally, to estimate changes in
investments from the pre- to post-regulation period, I examine changes in firmsβ investments
recognized in financial statements, because firmsβ off-balance sheet purchase obligations are not
reported prior to the regulation. This assumes that changes in off-balance sheet purchase
obligationsβsuch as commitments to inventory purchases, CAPEX, R&D, and advertising
expensesβare soon reflected on firmsβ balance sheets, income statements, or statements of cash
flows.
These two assumptions are reasonable, as purchase obligations reflect non-cancellable
payments for firmsβ future contractual obligations. However, I further run two validation tests to
provide evidence supporting these two assumptions, respectively. First, I run regressions for the
post-regulation period as follows:
ππππππππβπππΌπΌπΌπΌπππππππππππππππππππΌπΌπΌπΌππ,π‘π‘
= πΌπΌ1πππππΌπΌπππΌπΌπππππΌπΌπππΆπΆπππΌπΌπππππππππππΌπΌππ + οΏ½π½π½πΆπΆπππΌπΌπππππππππΌπΌππ,π‘π‘ + ππππππππ Γ πππ‘π‘ + πΎπΎππ + ππππ,π‘π‘, (5)
where the dependent variable is either the log of 1 plus the total amount of purchase obligations
scaled by total assets or an indicator that takes the value of 1 if purchase obligations are reported
in a given firm-year, and 0 otherwise. The key independent variable is the annual average number
33
of investment contracts in pre-regulation years, including both redacted and non-redacted ones.
ππππππππ Γ πππ‘π‘ are industry by year fixed effects, and πΎπΎππ are firm fixed effects.
The results of the regressions are tabulated in Panel A of Table 7. The coefficients πΌπΌ1 on Pre-
regulation Average Investment Contracts are positive and significant. This suggests that firms with
more investment contractsβredacted or non-redactedβare more likely to report a greater amount
of purchase obligations after the regulation. The coefficient of 0.266 in Column (1) suggests that,
for an average firm, one additional investment contract in the pre-regulation period (i.e., 0.2
contract per pre-regulation year) increases the reported amount of purchase obligations scaled by
total assets by 7% to from 25% to 32%.31 The coefficient on 0.513 in Column (2) suggests one
additional investment contract in the pre-regulation period increases the probability of reporting
purchase obligations by 10.3% (=0.2Γ0.513).
This finding confirms that firms with more investment contracts pre-regulation are more likely
to report a greater amount of purchase obligations in their 10-Ks post-regulation, which makes my
assumption more plausible that firms with more redacted investment contracts experience a greater
increase in their disclosure of investments (i.e., provide new disclosures about a larger amount of
investments). These findings are also consistent with those of Moon and Phillips (2019), who use
purchase obligation data to measure the extent of firmsβ production outsourcing.
Second, I run the following regressions on a subset of firm-years that report purchase
obligations in the post-regulation period:
31 πΌπΌln(1+0.25)+0.2Γ0.266 β 1=31.8%, where 0.25 is the average value of purchase obligations scaled by total assets (Panel B of Table 1). I find significant results for both dominant and non-dominant firms.
34
πππΌπΌππ ππππππππππ πΌπΌπΌπΌπΌπΌπΌπΌπΌπΌπππΌπΌπΌπΌπΌπΌπππΌπΌππ,π‘π‘+ππ

+ ππππ,π‘π‘, (6)
where the dependent variable is the average amount of total investments recognized in financial
statements (i.e., balance sheet, income statement, and cash flow statement) in the subsequent 2, 3,
or 5 years scaled by total assets multiplied by 100, and the key independent variable is the log of
1 plus the total amount of purchase obligations reported in a given year scaled by total assets.
ππππππππ Γ πππ‘π‘ are industry by year fixed effects, and πΎπΎππ are firm fixed effects.
Panel B of Table 7 reports estimates from the regressions. The coefficients πΌπΌ1 across columns
(1)β(3) indicate that, for a firm with the average value of total investments, a 10% increase in 1
plus the amount of purchase obligations scaled by total assets increases the future investments
recognized in financial statements by 2.1%, 1.6%, and 1.0%, respectively, for the subsequent 2, 3,
and 5 years.32 These results are consistent with the fact that purchase obligations reflect non-
cancellable, legally binding amounts of payments. Moreover, this positive relationship supports
my assumption that off-balance sheet purchase obligations are soon reflected in firmsβ financial
statements, and therefore validates interpreting changes in investments as stemming from changes
in purchase obligations.33
My second set of tests in this section is aimed at validating the robustness of my main findings
to other research design choices. I show that my results are robust to (i) using alternative measures
not based on Kedia (2006) to classify competition as strategic substitutes and complements, (ii)
using a dichotomous variable to capture firmsβ exposure to the 2003 regulation (i.e., ex ante
32 2.1% = 10% Γ 20.997/100; 1.6% = 10% Γ 15.698/100; 1.0% = 10% Γ 10.273/100. 33 I also find significant results when running regressions separately for dominant and non-dominant firms.
35
βtreatmentβ) instead of a count variable, and (iii) using a 4-year window around the 2003 regulation
(i.e., 2 years before and after) instead of a 10-year window.
First, I re-estimate model (1) for dominant firms and model (2) for non-dominant firms
separately for those identified as having strategic substitutes and strategic complements using
alternative measures, and I find that my results do not change much in terms of magnitude and
statistical significance. I use the three alternative measures used by Bloomfield (2019): production
flexibility, R&D spending, and the mining sector. In Table 8, I tabulate results of using the
production flexibility measure and the R&D spending measure as proxies for competition type.
For brevity here, the results of using the last measure that conservatively uses only firms in the
mining sector as firms with strategic substitutes are tabulated in my online appendix, because the
measure only uses 57 dominant firm-years and 42 non-dominant firm-years.
The use of the production flexibility measure is based on the idea that firms with strategic
substitutes have a greater amount of fixed capital (e.g., Kreps and Scheinkman 1983; Maggi 1996).
I classify a firm as facing competition with strategic substitutes if the average gross PP&E over
total assets of its competition group is above the median of all competition groups, where the
competition group consists of the firm itself and its 5 nearest competitors identified by Hoberg and
Phillips (2010, 2016). I classify a firm as facing competition with strategic complements if the
average of its competition group is below the median.
The use of the R&D spending measure is based on the idea that firms with strategic
complements on average have a greater degree of product differentiation (e.g., Chamberlin 1933;
Lancaster 1966; Schmalensee 1982; Singh and Vives 1984). I classify a firm as facing competition
with strategic complements if the average R&D expense over total assets of its competition group
is above the median of all competition groups, and as facing competition with strategic substitutes
if the average is below the median.
36
Panels A and B of Table 8 show results for dominant firms and non-dominant firms,
respectively. I continue to find results consistent with my hypotheses H1a, H1b, and H2. In Panel
A, I find that dominant firms with a greater increase in investment observability increase their
investments by a greater amount if they have substitutive strategies, and reduce them by a greater
amount if they have complementary strategies. Similarly, in Panel B, I find that both non-dominant
firms with substitutive strategies and those with complementary strategies reduce investments in
response.
Second, I show that my results are robust to using a dichotomous ex ante βtreatmentβ measure
and a shorter time window around the 2003 regulation date. I again re-estimate model (1) for
dominant firms and model (2) for non-dominant firms separately for those with strategic
substitutes and strategic complements using these alternative research design choices.
In Panel A of Table 9, I use a dichotomous version of PreRegRedaction in models (1) and (2)
to capture the extent of firmsβ exposure to the 2003 regulation, which relaxes the assumption that
a higher frequency of redacted contracts pre-regulation implies a greater exposure to the 2003
regulation. For a dominant firm, the variable takes the value of 1 if the firm has at least one redacted
investment contract prior to the regulation, and 0 otherwise. For a non-dominant firm, the variable
takes the value of 1 if the firmβs dominant competitors have at least one redacted investment
contract, and 0 otherwise. In Panel B of Table 9, I use a 4-year window surrounding the regulation
dateβ2 years before and afterβto address concerns that my results are driven by the dot-com
bubble that burst in 2000. It is unlikely that my redaction-based measure of firmsβ exposure to the
2003 regulation is correlated with firmsβ exposure to the bubble in opposite ways for firms with
strategic substitutes and for those with strategic complements. However, I further conduct tests
using two firm-years before and after the 2003 regulation date. In both Panels of Table 9, I continue
to find results consistent with my hypotheses H1a, H1b, and H2.
37
I perform additional validation or robustness tests, which are tabulated in my online
appendix.34 There, I show that the disclosures required by the 2003 regulation reduced information
asymmetry measured by analyst dispersion, which suggests the disclosures are likely informative
about firmsβ future operations to outsiders (including competing firms). I also show that my results
for H1a, H1b, and H2 are not sensitive to how I identify investment contracts, whether I include
firms with no investment contracts in the control group or not, and whether I use firms in the
mining sector as firms with strategic substitutes.

6. Conclusion
I provide novel evidence that financial reporting increases the strategic role of investments by
making investments more visible to competitors. The evidence suggests that, after an increase in
disclosures about future investments, large firms strategically increase or decrease investments to
affect competitorsβ behavior. This is because investments serve as an effective commitment
mechanism, and better observability of investments further increases their strategic value. My
findings also suggest that this strategic behavior has significant impacts on product market
outcomes, such as firmsβ COGS, sales, and profit margins. These findings expand our limited
understanding of the role of mandatory corporate disclosures in firmsβ strategic investments and
their implications (Roychowdhury et al. 2019).
This paper also makes an important contribution to the investment literature by underscoring
the economic significance of off-balance sheet purchase obligations and their strategic uses. My
findings suggest that papers studying investments may benefit from examining purchase
obligations. They include future expenditures for operations (e.g., inventory purchases,
advertising/marketing) as well as for fixed assets and innovations (e.g., CAPEX, R&D), and
therefore reflect wide-ranging future strategies in a timely manner.
Finally, my paper should be of interest to regulators such as the SEC and FASB. The 2003
regulation was intended to provide investors with information about firmsβ off-balance sheet
obligations. My finding that firms, especially large firms, exploit it to make a gain sheds light on
an unintended effect of the regulation and an unexplored role of financial reporting in competition.
Furthermore, to the extent that disclosures in financial statements are more credible and
informative about future investments, my finding speaks to the recent debate of whether rights and
obligations from executory contracts, such as operating leases and purchase obligations, should be
recognized in balance sheets.

Appendix C: Strategic Substitutes and Complements and Their Empirical Proxies
Bulow et al. (1985) theoretically derives notions of strategic substitutes and strategic
complements, which fundamentally affect the way firms interact with their competitors. They first
construct firm iβs strategic interaction variable Ξ ππππππ = β2Ξ ππ
βxiπ₯π₯ππ, which is the cross-partial of firm iβs
profit Ξ ππ with respect to both the aggressiveness of firm iβ own strategy π₯π₯ππ and the aggressiveness
of competitor jβs strategy π₯π₯ππ. The greater π₯π₯ππ ππππ ππ is, the more aggressive firm i or j is. They show
that, if Ξ ππππππ is less than zero, then firms i and j have strategic substitutes, and if Ξ ππππππ is greater than
zero, then firms i and j have strategic complements.
The intuition is that Ξ ππππππ is equal to ββxj
(ππΞ i
πππ₯π₯ππ), which can be interpreted as firm i's marginal
profitability with respect to π₯π₯ππ when competitor jβs strategy π₯π₯ππ becomes more aggressive.
Equivalently, Ξ ππππππ captures firm iβs optimal response to changes in competitor jβs strategy π₯π₯ππ, or the
βslopeβ of firm iβs best response function with respect to competitor jβs strategy π₯π₯ππ. The sign of
Ξ ππππππ is determined by firms i and jβs demand functions (e.g., elasticity) and cost functions (e.g.,
decreasing marginal cost). A commonly accepted example of competition with strategic substitutes
is Cournot competition, and of competition with strategic complements is Bertrand competition
(Bulow et al. 1985). This categorization is true under general conditions, such as when demand is
linear and marginal cost is constant.
In Cournot competition, firms compete in quantity. The greater competitor jβs quantity π₯π₯ππ is,
the more aggressive competitor j is. If competitor j increases its aggressiveness by increasing its
quantity, then the marginal profitability of firm i is affected. Firm i re-optimizes such that its
marginal profitability is zero, or its marginal revenue is equal to marginal cost.
46
Appendix C (contβd): Strategic Substitutes and Complements and Their Empirical Proxies
When marginal cost is assumed to be constant, firm iβs reaction solely depends on whether an
increase in competitor jβs quantity increases or decreases firm iβs marginal revenue (with respect
to quantity), which can be expressed as follows:
ππππππ = πππποΏ½ππππ , πππποΏ½ οΏ½1 +1ΞπποΏ½ , where Ξππ =
ππππππ/ππππππππππ(ππππ, ππππ)/ππππ(ππππ, ππππ)
.
If competitor j increases its aggressiveness by increasing its quantity, then the market-clearing
price of firm iβs product πππποΏ½ππππ, πππποΏ½ goes down by the law of demand, as the two firmsβ products
are (imperfect) substitutes. As long as the elasticity Ξππ does not change much around the
equilibrium point, the reduction in πππποΏ½ππππ, πππποΏ½ decreases marginal revenue and, hence, marginal
profitability of firm i. Therefore, the optimal reaction of firm i is to reduce its quantity π₯π₯ππ (i.e.,
reduce its aggressiveness) and bring up its marginal revenue to its marginal cost. This negative
relationship between competitor jβs aggressiveness and firm iβs marginal profitabilityβΞ ππππππ =
ββxjοΏ½ππΞ
i
πππ₯π₯πποΏ½ < 0βmakes them to be in competition with strategic substitutes.
In Bertrand competition, firms compete in quality or the inverse of price. The higher
competitor jβs quality π₯π₯ππ is, the more aggressive competitor j is, or the higher competitor jβs inverse
of price π₯π₯ππ is, the more aggressive competitor j is. For the sake of a simpler illustration, suppose
the unit of aggressiveness π₯π₯ is price. If competitor j increases its aggressiveness by reducing its
price, the marginal profitability of firm i is affected. Firm i adjusts its aggressiveness such that its
marginal profitability is zero, or its marginal revenue is equal to marginal cost.
47
Appendix C (contβd): Strategic Substitutes and Complements and Their Empirical Proxies
When marginal cost is assumed to be constant, firm iβs reaction solely depends on whether a
reduction in competitor jβs price increases or decreases firm iβs marginal revenue (with respect to
price), which can be expressed as follows:
MRi = ππππ οΏ½1 +1ΞπποΏ½ , where Ξππ =
ππππππ(ππππ,ππππ)/qi(ππππ,ππππ)ππππππ/ππππ
.
If competitor j increases its aggressiveness by reducing its price, then the demand for firm iβs
product goes up, and, when the demand is linear, the demand for firm iβs product becomes more
elastic (i.e., more sensitive to prices). This increases the value of οΏ½1 + 1ΞπποΏ½. This in turn increases
marginal revenue and, hence, marginal profitability of firm i. Therefore, the optimal reaction of
firm i is to reduce its price π₯π₯ππ (i.e., increase its aggressiveness) and bring down its marginal revenue
to its marginal cost. This positive relationship between competitor jβs aggressiveness and firm iβs
marginal profitabilityβthat is, Ξ ππππππ = ββxjοΏ½ππΞ
i
πππ₯π₯πποΏ½ > 0 βmakes them to be in competition with
strategic complements. It is straightforward that the same result is obtained if we define the unit
of aggressiveness π₯π₯ to be quality ππ, and define price ππ(ππ) as a decreasing function of quality (i.e.,
increasing quality is analogous to reducing price).
However, Cournot competition may have strategic complements, and Bertrand competition
may have strategic substitutes, if we allow for some variations in the local curvature of firmsβ
demand or cost functions. Moreover, not all firms can be categorized as having quantity, price, or
quality competition, as most have discretion over all of these factors. Therefore, as suggested by
Bulow et al. (1985), I rely on an empirical proxy to identify competition with strategic substitutes
48
Appendix C (contβd): Strategic Substitutes and Complements and Their Empirical Proxies
and complements, instead of relying on theory to identify whether competition is in quantity, price,
or quality.
In order to empirically estimate the relationship between βΞ i
πππ₯π₯ππ and πππ₯π₯ππ (i.e., which determines
the sign of Ξ ππππππ = β2Ξ i
βxiπ₯π₯ππ= β
βxj(ππΞ
i
πππ₯π₯ππ) ), Sundaram et al. (1996) compute correlation coefficients
between ΞΞ i
Ξπ₯π₯ππ and Ξxj. They use quarterly changes in profits and sales of firm i as proxies for ΞΞ i
and Ξxi, respectively, and a quarterly change in the average sales of all other firms in the same
four-digit SIC industry group as a proxy for Ξxj . To address the concern that correlation
coefficients can be confounded by common supply or demand shocks (e.g., reduction in the cost
of raw materials), Kedia (2006) introduces a regression-based measure that captures the
relationship between ΞΞ i
Ξπ₯π₯ππ and Ξxj while controlling for changes in firm iβs strategy Ξxi. Below, I
provide details on how Kedia (2006) constructs her measure for firm iβ strategic interaction Ξ ππππππ .
Kedia defines firm i's profit as:
Ξ ππ = π·π·πποΏ½π₯π₯ππ, π₯π₯πποΏ½π₯π₯ππ β πΆπΆπποΏ½π₯π₯ππ, π₯π₯πποΏ½,
where π·π·πποΏ½π₯π₯ππ, π₯π₯πποΏ½ is the demand function, and πΆπΆπποΏ½π₯π₯ππ, π₯π₯πποΏ½ is the total cost function for firm i. The
demand function reflects that firms i and j are direct competitors facing the same targeted
customers. To derive an empirical estimation of the cross-partial Ξ ππππππ = β2Ξ i
βxiπ₯π₯ππ= β
βxj(ππΞ
i
πππ₯π₯ππ), Kedia
first takes the total differential of firm iβs marginal profit ππΞ i
πππ₯π₯ππ with respect to π₯π₯ππ and π₯π₯ππ:
49
Appendix C (contβd): Strategic Substitutes and Complements and Their Empirical Proxies
ππππΞ ππ
πππ₯π₯ππ= Ξ ππππππ πππ₯π₯ππ + Ξ ππππππ πππ₯π₯ππ .
Because the second derivatives are Ξ ππππππ = π·π·ππππππ οΏ½π₯π₯ππ , π₯π₯πποΏ½π₯π₯ππ + 2π·π·πππποΏ½π₯π₯ππ , π₯π₯πποΏ½ β πΆπΆππππππ (π₯π₯ππ , π₯π₯ππ) and Ξ ππππππ =
π·π·ππππππ οΏ½π₯π₯ππ , π₯π₯πποΏ½π₯π₯ππ + π·π·πππποΏ½π₯π₯ππ , π₯π₯πποΏ½ β πΆπΆππππππ (π₯π₯ππ, π₯π₯ππ), we have:
ππππΞ ππ
πππ₯π₯ππ= [π·π·ππππππ οΏ½π₯π₯ππ , π₯π₯πποΏ½π₯π₯ππ + 2π·π·πππποΏ½π₯π₯ππ, π₯π₯πποΏ½ β πΆπΆππππππ (π₯π₯ππ, π₯π₯ππ)] πππ₯π₯ππ + [π·π·ππππππ οΏ½π₯π₯ππ , π₯π₯πποΏ½π₯π₯ππ + π·π·πππποΏ½π₯π₯ππ, π₯π₯πποΏ½
β πΆπΆππππππ (π₯π₯ππ, π₯π₯ππ)]πππ₯π₯ππ .
This can be re-written as:
ππππΞ ππ
πππ₯π₯ππ= [π½π½1π₯π₯ππ + π½π½2] πππ₯π₯ππ + [π½π½3π₯π₯ππ + π½π½4]πππ₯π₯ππ
= π½π½1π₯π₯πππππ₯π₯ππ + π½π½2πππ₯π₯ππ + π½π½3π₯π₯πππππ₯π₯ππ + π½π½4πππ₯π₯ππ ,
where π½π½1 = π·π·ππππππ οΏ½π₯π₯ππ , π₯π₯πποΏ½, π½π½2 = 2π·π·πππποΏ½π₯π₯ππ , π₯π₯πποΏ½ β πΆπΆππππππ οΏ½π₯π₯ππ, π₯π₯πποΏ½, π½π½3 = π·π·ππππππ οΏ½π₯π₯ππ, π₯π₯πποΏ½, and π½π½4 = π·π·πππποΏ½π₯π₯ππ, π₯π₯πποΏ½ β
πΆπΆππππππ οΏ½π₯π₯ππ , π₯π₯πποΏ½. So, the strategic interaction Ξ ππππππ is given by π½π½3π₯π₯ππ + π½π½4 . Similar to Sundaram et al.
(1996), Kedia (2006) uses quarterly sales and profits of firm i to proxy for π₯π₯ππ and Ξ ππ, respectively,
and defines as competitor j all of the rest of the firms in the same four-digit SIC industry group.35
The following OLS regression model can be used to estimate π½π½3οΏ½ and π½π½4οΏ½:
ΞΞππππππππππππππ,π‘π‘ΞπΌπΌπππππΌπΌπΌπΌππ,π‘π‘
= π½π½1πΌπΌπππππΌπΌπΌπΌππ,π‘π‘ΞπΌπΌπππππΌπΌπΌπΌππ,π‘π‘ + π½π½2ΞπΌπΌπππππΌπΌπΌπΌππ,π‘π‘ + π½π½3πΌπΌπππππΌπΌπΌπΌππ,π‘π‘ΞπΌπΌπππππΌπΌπΌπΌππ,π‘π‘ + π½π½4ΞπΌπΌπππππΌπΌπΌπΌππ,π‘π‘,
35 According to Kedia (2006), with linear demand functions and constant marginal cost, using sales as a proxy for a firmβs aggressiveness (i.e., firm-level price and output) yields the same sign as the true strategic interaction though it differs in magnitude. Therefore, I exploit the sign of the interaction to determine the nature of competition and do not consider its magnitude.
50
Appendix C (contβd): Strategic Substitutes and Complements and Their Empirical Proxies
where πΌπΌπππππΌπΌπΌπΌππ is the average contemporaneous quarterly sales of all other firms in the same four-
digit SIC group. The sign of the estimator π½π½3οΏ½ πΌπΌπππππΌπΌπΌπΌοΏ½οΏ½οΏ½οΏ½οΏ½οΏ½οΏ½ππ + π½π½4οΏ½, where πΌπΌπππππΌπΌπΌπΌοΏ½οΏ½οΏ½οΏ½οΏ½οΏ½οΏ½ππ is the average quarterly
sales of firm i, reflects the nature of the competition that firm i faces. If π½π½3οΏ½ πΌπΌπππππΌπΌπΌπΌοΏ½οΏ½οΏ½οΏ½οΏ½οΏ½οΏ½ππ + π½π½4οΏ½ < 0, it has
strategic substitutes with its competitors. If π½π½3οΏ½ πΌπΌπππππΌπΌπΌπΌοΏ½οΏ½οΏ½οΏ½οΏ½οΏ½οΏ½ππ + π½π½4οΏ½ > 0, firm i has strategic complements.
If π½π½3οΏ½ πΌπΌπππππΌπΌπΌπΌοΏ½οΏ½οΏ½οΏ½οΏ½οΏ½οΏ½ππ + π½π½4οΏ½ is not significantly different from zero, firm i does not face any strategic
interactions.
