1. Introduction
Almost ten years have passed since the 2008 crisis, this provides a time frame long enough
to observe the effects that the Great Recession had in macroeconomics and business cycle
theory. According to observed reactions, the largest impact produced by the crisis has been
to the status of dynamic stochastic general equilibrium (DSGE) models. In words of
(Stiglitz, 2011, p. 592), if prediction is the standard test of a scientific theory, then
macroeconomic models such as DSGE have failed “miserably.” DSGE models proved
inadequate to predict, explain, and remedy one of the largest crises in the twentieth
century.
This situation has produced a different set of reactions with respect to what changes
should macroeconomics go through to fill the gap between what macroeconomics can
explain and what it should explain. These reactions can be divided in three groups. The first
one consists in continue applying macroeconomic theory such as DSGE models as if nothing
had happened. The 2008 crisis was a big albeit rare even that does not justify making
significant changes to macroeconomic theory. The second type of reaction consists in fixing
and expanding the DSGE model to take into account the missing pieces that would allow for
this theory to better fit into how business cycles can evolve. The third type of reaction
advocates for a full rejection of DSGE modeling and replace it with one that is better suited
to deal with real world events.
Following (Caballero, 2010), we locate DSGE models in the core of macroeconomic theory
being other models and non-DSGE research the periphery of the field. Interestingly, some of
the reactions in the macroeconomic literature have stepped outside conventional

macroeconomic theory (into the periphery of the periphery) to bring new theoretical
insights into business cycle theory. This is because there are two important characteristics
present in the 2008 crisis that do not have room in DSGE modeling; (1) the development of
a cluster of errors and (2) a cascade effect. The incipient Austrian turn in macroeconomics
observed after the 2008 crisis is pointed to deal with these issues. A number of scholars
have turned to the Austrian literature, in particular to the Austrian Business Cycle Theory
(ABCT) as a way to explain what went wrong in the 2008 crisis.
We argue that in conventional macroeconomics there is still room for a sharper Austrian
turn. In other words, there are still gains from trade on engaging issues that have been
traditionally present in the Austrian literature. Following the macroeconomic literature
discussed below, we rely on the ABCT to account for the cluster of errors and on Fisher’s
debt-deflation (FDD) theory to describe the cascade effect that can be observed during a
crisis.
The paper is divided into two main sections. The first one reviews the situation of
macroeconomics after the crisis, with an emphasis on its core, DSGE models. The second
one discusses the contributions that can take place with a deeper Austrian turn in
macroeconomics. We divide these contributions in five: (1) Hayek’s knowledge problem
applied to monetary policy, (2) the rule of law versus the rule of experts in monetary
policy, (3) the loss of confidence and the cascade effect, (4) the Wicksell Effect, and (5) the
average period of production during a business cycle. The last section concludes.

2. Macroeconomics after the Crisis
The 2008 crisis challenged well-grounded conventional macroeconomic knowledge. The
core, rather than a mere component of the periphery, received a significant empirical
disconfirmation. The crisis showed that a stable low inflation is no guarantee that serious
imbalances are not growing in the economy and that the credit allocation through the
financial market can be a key component of business cycles. This characteristic of the crisis
contrasts with how common is for DSGE models to be modelled without money. The Great
Moderation period that preceded the crisis seems to have feed false confidence in the DSGE
and core of macroeconomic theory (Blanchard, 2014; Blanchard, Dell’Ariccia, & Mauro,
2010).
After the crisis, a series of criticisms to DSGE modeling have been raised by a number of
scholars. (Blanchard, 2016; Keen, 2018) question the lack of reality of the assumptions
used in this type of modeling. The issue with the assumptions used in the core of
macroeconomics is not that they simplify the economic reality, which is what assumptions
are used for. The problem is that they are unreal and therefore the model does not depict
the economic process as it occurs in the real world. A map, for instance, is a simplification
of the real world if its assumptions do not alter the geographical accidents to the point
where the map becomes a reflection of a difference world. Similarly, the issue with DSGE
modeling is that it does not offer a fair representation of the problems faced by the policy
maker. This means that even if the model is calibrated to fit real world data, its foundations
have no anchor to reality and the stance of the economy might become misjudged. If the
reality of the model is an important issue, then there is no clear way to discern which one
of all different potential models is the correct one. The prioritization of mathematical

tractability over reality of the assumptions lead macroeconomics to develop complex
models that rely on assumptions that are not easy to adjust in isolation from the rest of the
model.
Concerns about DSGE modeling do not rest only on academic discussions about the reality
of the assumptions used. (Canova & Sala, 2009; Romer, n.d.; Stiglitz, 2011), for instance,
point to the problem of model identification already noted by (Liu, 1960; Sims, 1980). This
issue is not a minor one. A Walrasian DSGE model with n equations and n unknowns needs
𝑛2 parameters to be identified with values exogenously given information. The
identification requirement increases even further with the inclusion of rational
expectations into the model. This means that the more accurate and subtle the models are,
the more exogenous information is needed. Different calibrations can yield results that look
correct even if their internal dynamics do not reflect the market process accurately. But, it
remains unknown whether or not the calibrated values are correct. Calibrated values may
rest on a strong intuition, but as strong as this intuition is it may be can still be mistaken.
Looking for answers, macroeconomists have turned into the ABCT as a theory useful to
explain why the 2008 crisis happened. Just at first sight, data matches the general pattern
of this theory. A low interest rate policy contributed to build the housing bubble that burst
after the Federal Reserve started to increase the Federal funds rate. Another reason for this
endorsement is that the DSGE modeling is not well suited to deal with the cluster of errors
observed in the housing bubble, but the ABCT does offer an explanation for such clustering.
Some of this literature offers an explicit endorsement to the ABCT (Borio & Disyatat, 2011;
Diamond & Rajan, 2009a; Hume & Sentance, 2009; Leijonhufvud, 2009a; W. R. White,
2012). Probably the most friendly exposition to the ABCT explanation of the 2008 crisis is
Nicolás Cachanosky and Roger Koppl

Page 6 of 25
(Calvo, 2013). But in other cases, even though an explicit endorsement to the ABCT is
absent, still a very Austrian-friendly explanation is offered (Diamond & Rajan, 2009b;
Gjerstad & Smith, 2009; McKinnon, 2010; Meltzer, 2009; Schwartz, 2009; Taylor, 2009).
This suggests that insights from this theory are already more present in macroeconomics
than is usually acknowledge.1 Note, also, that while the DSGE modeling usually does not use
financial markets as a channel of a crisis, credit is at the core of the ABCT. This has probably
been the most appealing angle found in the ABCT to make sense of the 2008 crisis.
(Cachanosky & Salter, 2017) offer a more detailed analysis of the literature discussed in
this paragraph.
3. Austrian Insights into Macroeconomics
3.1. The Knowledge Problem
(Hayek, 1948) knowledge problem is well known in the context of the socialist economic
calculation debate. However, some of his arguments also apply to the making of monetary
policy. To understand why Hayek’s problem also has implications to monetary policy we
need first to focus on two of his main points
The first one, and the probably the more familiar one, is about the dispersion of
information across the economy. Information is not given to economic agents in the same
way it is “given” to the economist who is building a model. Information is an unintended
1 In some sense this is not much of a surprise. For isntance, (Lewin, 1999, pp. 73–75) argues that Böhm-
Bawerk’s average period of production is compatible with the neoclassical tradition leading to growth theory.
According to (L. H. White, 2016), Lucas’ influential islands model is inspired in Hayek, even though posterior
development turned business cycle theory towards real business cycle (RBC) and DSGE models.

spontaneous outcome of the market process. Hayek’s point, however, is not just that
information is disperse as small bits of information, but that such information cannot exist
outside the market process. Without private property, there can be no transaction, and
without transactions there is no information to recollect in the first place.
The second point in Hayek’s argument, is the distinction between information and
knowledge (Zanotti, 2011). The former is objective and quantitative, such as prices and
quantities. As such, it can be complete (perfect) or incomplete (imperfect.) The latter is
subjective and qualitative, it can be neither complete nor incomplete. Information does not
speak by itself, it requires interpretation which depends on knowledge (i.e. a theory that
makes sense of the data.) This distinction between information and knowledge is
important because it shows that to assume perfect information is not enough to guarantee
that the economy will reach equilibrium. How to read the information correctly and, in
particular, how to discover market disequilibria that remain invisible to other economic
agents is the role of the entrepreneur (Kirzner, 1973).
There are a few ways this relates to central banking and the doing of monetary policy. A
main difference is that there is no market process through which to filter inefficient policy
makers in a similar way market competition drives out inefficient entrepreneurs. In
addition, the presence itself of a central bank eliminates the market process through which
the money and credit market converges towards equilibrium (more on this in the next
section.) This means that entrepreneur and the central bank face knowledge problems of
different difficulty. The former uses market information such as prices and quantities as an
input to discover market disequilibria. This alertness, in turn, is subject to market
competition. The central bank, however, cannot rely on credit market information because
Nicolás Cachanosky and Roger Koppl

Page 8 of 25
their policy decisions do not go through market competition. Different to a market with
freedom of entry and exit, what is considered a good monetary policy depends on the
knowledge of the time, not on an objective market outcome such as profits and losses.
From this discussion, it follows that a policy makers does not only need to be a good
technician knowledgably of monetary theory. He also needs to have a type of alertness that
is superior to entrepreneurial alertness in the sense that the central bank needs to be able
to read the market disequilibria correctly, but without being motivated by competition and
without the market information that the entrepreneur has access to.
The central bank knowledge problem is further increased by its condition of being a Big
Player (Koppl, 2002, Chapter 7). An economic agent is a Big Player if its behavior can
produce a Lucas-critique type of effect in the economy. An entrepreneur in a competitive
market takes the market dynamics and incentives as given. A Big Player action, however,
can change either market dynamics or incentives (i.e. a change in policy or regulation). The
central bank is in a more difficulty position than forming a pattern prediction of the
economy situation in the foreseeable future with the market dynamics taken as given. The
Big Player needs to forecast the intended and unintended consequences of his action and
from there the reaction of the economic agents.
3.2. Rule of Law versus the Rule of the Experts
The more is asked for a central bank, and the more costly deviations from monetary
equilibrium are, the more important it becomes for the monetary authority to follow a
well-designed rule rather than rely on discretion. If we lack the sort of knowledge assumed
to be in standard models, then a rules-based approach to macroeconomics has a stronger

Page 9 of 25
case. Note that the models assume that the economic agents know the model they are living
in. This is the distinction mentioned above between information (economic data) and
knowledge (what the data means.) Even if we assume incomplete information, the model
still assumes economic agents have the right knowledge.
The rule of law has a distinctive presence in the Austrian institutional literature. Hayek is
probably the most important rule of law theorist since Dicey. (Hayek, 1976)
Denationalisation of Money can be seen as a radical reform that moves issuer banks
towards being under the law rather than allowing them to set their objectives and rules.
Some of these Austrian ideas has been extended to monetary policy as well, in particular by
(L. H. White, 2010).
To be under the rule of law is a more strict deviation from discretion than it is to choose
and follow a rule. Under the rule of law the policy maker has no discretion to update or
deviate from the law even if there are short-run benefits by doing so. The reason is that the
cost of devaluing the law by each discretionary deviation has a long-run costs that can
more than offset the short-run benefit. An example would be applying Bagehot’s rule,
where only solvent but illiquid banks should be eligible for a bailout loan. Under the rule of
law there would be no deviation from this principle even if the failure of a bank could
impose costs in the short-run. The long-run costs through moral hazard behavior on part of
the banks can easily become a larger problem than the short-run bank failure.2 The cost-
benefit analysis of rule deviation should also include the cost of eroding the rule.
2 It should be noted that Bagehot did not endorse the need of having a central bank to perform as a lender of
last resort. Rather, Bagehot position was that taken a central bank as given, its behavior shouold be to let

If there is no rule of law, then the alternative is the rule of the experts. Macroeconomic
theory has evolved around the latter concept rather than the former. Either discretion or
rules in the traditional debate requires an expert to either be discretionary or chose and
implement the right rule. A rule of law evolution of macroeconomics would be more
focused on studying the market process than in controlling it through policy in a similar
way a biologist studies an ecosystem but does neither create it nor rule it. The fact that
macroeconomics has evolved with the rule of expert as part of its core makes it particular
challenging to adopt the alternative rule of law; hence the opportunity to turn to the
Austrian literature on this issue.
One way to move monetary policy closer to rule of law outcome would be for central banks
to target the same outcome that a free market of money and banking under the rule of law
produces. This is where the literature on free banking becomes informative, for which the
self-regulation mechanism of a free market of money and banking is the main topic.3 One of
the outcomes of this research is that the financial market spontaneously stabilizes nominal
income without the need to target it in the first place. In terms of contemporary debates,
this is the idea behind Market Monetarism’s NGDP Targeting (Sumner, 2012, 2013).4
However, since the Keynesian revolution monetary policy is more focused on price level
insolvent banks fail. See the comment in (Selgin, 1996, p. 228). According to (Bagehot, 1873, pp. 65–69) own
words, free banking would be the first best scenario, Bagehot’s rule becomes the second best choice in a world
of central banks as given institutions. Bagehot might be wrong in seeing free banking as superior to central
banking, but it does not follow from his writing that central banking was his recommendation.
3 For a more detailed analysis of free banking see (Cachanosky, 2010; Dowd, 1992; Hasan, 1994; Laidler,
2005; Sechrest, 1993; Selgin, 1988, 1996, Chapters 1, 2; Smith, 1936; L. H. White, 1984).
4 Even though the idea of NGDP Targeting has seen a renewed interest in recent years, the idea had some
presence as well prior to the 2008 crisis (Bean, 1983; Bradley & Jansen, 1989; Feldstein & Stock, 1994; Hall &
Mankiw, 1994; Kahn, 1988; Taylor, 1985).

stability and unemployment than on nominal income stability. Price level stability,
however, is consistent with monetary equilibrium only if certain conditions hold. In
particular, in the presence of productivity gains an increase in money supply that offsets a
fall in prices produces an excess of money supply with respect to money demand (Selgin,
1996, Chapter 7, 1997).5 This one of the reasons why (Hayek, 1931, p. 124, 1937, pp. 83–
84) refers as a neutral monetary policy keeping nominal income (money supply times
velocity of circulation) constant in per capita terms. The difference between Market
Monetarism’s NGDP Targeting and Hayek’s rule rests on the target growth rate of NGDP.6
As (Selgin, 1996, Chapter 8) argues, before the Keynesian revolution, Hayek’s
recommendation to stabilize nominal income was shared among a number of monetary
scholars rather than being just an Austrian position. As (L. H. White, 2008) shows, to
sustain that either the ABCT or Hayek are in favor of a “do nothing” policy when a crisis
triggers is a misinterpretation of this theory. What Hayek opposes is to increase M beyond
the fall in V as a monetary stimulus policy. (Selgin, Beckworth, & Bahadir, 2015) argue that
a higher rate of productivity gains in the years prior to the 2008 crisis misled the Federal
Reserve into assuming that the monetary policy was in the right track, while the case was
that the inflationary effect of a loose monetary policy was being offset by the gains in
5 Note that this bening deflation does not produce a depression; prices fall because there is an increase in
productivity, not because money demand is increasing (a fall in money velocity). For an empirical study see
(Atkenson & Kehoe, 2004).
6 While for NGDP Targeting nominal income should grow at a 5-percent per year, for Hayek NGDP per capita
should be constant. Later in his carrer, however, Hayek changed his mind towards price level stability (L. H.
White, 1999).

productivity.7 This is the concern behind monetary rules such as NGDP Targeting and
Hayek’s rule. This situation has also been considered by the ABCT literature.
3.3. Confidence and Cascade Effect
A loss of confidence (i.e. a Minsky moment) can trigger a cascade effect with significant
economic consequences. This is a situation for which DSGE models usually are not well
equipped to deal with. Writing in the context of the Great Depression, (Fisher, 1933) argues
that the combination of over-indebtness and deflation is what makes a crisis so acute. The
combination of these two issues trigger a sequential chain of events where debt and
deflation feed on each other. For Fisher (1933, p. 345) the Great Depression is an example
of the “most serious sort” of crisis. Fisher’s debt-deflation (FDD) theory can be described in
the following way. Starting from a point of over-indebtness, a loss of confidence puts into
motion a chain of events that can be logically ordered in the following nine steps:
1. Liquidation of debt (triggered by the debtor or creditor) leads to a fire sale of stock
in order to increase cash holdings.
2. Increase in money demand makes money velocity fall, and debt liquidation reduces
the money multiplier.
3. Because of (2), price deflation occurs (assuming the central bank does not interfere
with an expansionary policy.)
4. Deflation produces a great fall in the net worth of firms precipitating bankruptcies
due to insolvency.
7 Through a different argument, (Leijonhufvud, 2009a, 2009b) also argues that the focus on price level
stability misled the Federal Reserve.
Nicolás Cachanosky and Roger Koppl
IS MACROECONOMICS TAKING AN AUSTRIAN TURN?
Page 13 of 25
5. Because of deflation revenue also falls, this leads again to fire sales (number 1) and
profitable firms become unprofitable.
6. Output falls and unemployment rises. The rise in unemployment produces a fall in
the demand of final goods.
7. Fall in output and rise in unemployment produces pessimism and loss of confidence.
8. Situation number 7 leads to a further fall of money velocity (and therefore to an
increase in deflationary pressure.)
9. The 8-point logical sequence described above leads to “complicated” disturbances in
the interest rate, where nominal interest rates fall and real interest rises.
While Fisher presents this sequence of nine steps as a logical chain of events, he
acknowledges that empirically or chronologically the order might be somewhat altered and
that some steps might repeat (for instance point number five triggering the effect in point
number one again.) Fisher’s nine steps should be interpreted as a pattern effect rather than
as a precise prediction.8 A savvy monetary policy would cut this sequence of events if, for
instance, the monetary authority offsets the fall in the price level with an expansionary
monetary policy such that the deflation component of the theory is cancelled. This, of
course, is Hayek’s rule and NGDP Targeting prescription for monetary policy. The negative
effects of the reduction in the net worth are particularly clear in the case of financial
markets, which played a central role in both the Great Depression and the Great Recession.
ABCT and FDD can easily complement each other. A first point of connection between these
two theories is the required initial over-indebtness situation in the market. According to
8 The problem of point versus pattern prediction in economcis was a also a concern for (Hayek, 1967,
Chapters 1, 2).
Nicolás Cachanosky and Roger Koppl

Page 14 of 25
the ABCT, the excess of debt comes from an exogenous expansionary monetary policy
performed by the monetary authority. Fisher, however, gives more weight to origin of the
over-indebtness into investors’ enthusiasm of profits into new opportunities with high
profit expectations (this still resonates with (Hayek, 1933, Chapter IV) endogenous version
of the ABCT where banks issue more credit when misled by productivity gains). New
technological discoveries or an increase in total factor productivity (TFP) can lead firms to
issue too much debt under the expectation of receiving high rates of return.
Still, (Fisher, 1933) exposition does not imply that the only reason for over-indebtness is
through investor’s enthusiasm. In fact, in the first paragraph of the section that discusses
debt starters, (Fisher, 1933, p. 348) also sustains that “[e]asy money is the great cause of
over borrowing” and that “this was a prime cause leading to the over-indebtness of 1929.
Inventions and technological improvements created wonderful investment opportunities,
and so caused big debts” (p. 348, emphasis added.)
The second point of contact between the ABCT and FDD is that while the former is a theory
of unsustainable booms that little says about how a bust will play out, the former is focused
on the bust and less on the boom. In (Garrison, 2001, p. 120) words, the ABCT “is a theory
of the unsustainable boom. It is not a theory of the depression per se. In particular, it does
not account for the severity and possible recalcitrance of the depression that may follow in
the heels of the bust.” In short, FDD starts where the ABCT story stops.
3.4. The Wicksell Effect
(Borio, 2011, 2012, 2016), and in particular (Borio & Disyatat, 2011), refer to (Wicksell,
1898) natural rate of interest and the Wicksell Effect that occurs when there is a market

IS MACROECONOMICS TAKING AN AUSTRIAN TURN?
Page 15 of 25
deviation from it.9 Wicksell’s natural rate of interest is the rate level that equilibrates price
of goods across time. In other words, since the interest rate is the price of time, the natural
rate of interest is the level that equilibrates the allocation of time in production and
consumption. This is why for the ABCT a monetary policy that reduces interest rates might
produce an “over consumption” of time, which occurs as investment in projects that are too
long or too capital intense (for a more detailed exposition see next section.)
This is also why Hayek favors a stable nominal income as a neutral monetary policy that
would avoid interest rate deviations from its natural level. The fact that the natural rate is
ultimately unobservable is also a reason why a monetary rule that would let market forces
converge to the natural rate is likely to be more efficient than a discretionary approach.
While Hayek’s knowledge problem points to the convenience of a rule of law in the sphere
of monetary policy, (Borio & Shim, 2007, p. 12) are more inclined towards a discretionary
approach. The reason rests the “difficulties in designing built-in stabilisers.” The monetary
rule itself, however, does not need to be complex in the sense of being very specific on its
effects on different industries. Changes in money supply ultimately affect the whole
economy, not a single industry. What a monetary policy needs to do is actually target
monetary equilibrium, which is what Hayek’s rule and NGDP Targeting do. Other concerns
such as loan provisions, minimum capital requirements, loan-to-value rations, and
currency mismatching among others can be part of the discussion of financial regulation
without the need to be embedded in a rule that makes money supply match money
demand. It is even possible to have central banks focus only on monetary equilibrium and
another agency worry about financial stability.
9 On the natural rate of interest see (Anderson, 2005; Barro & Gordon, 1983; Garrison, 2012; Williams, 2003).

3.5. The Average Period of Production
The most questionable aspect of the ABCT is the lack of tractability of its most distinctive
component, the average period of production (APP) or roundaboutness.10 The lack of
tractability of APP makes it a challenge to be included in a formal model, DSGE or
otherwise. This problem was early recognized, and in a lost contribution, (Hicks, 1939, p.
138) offers a measurement of APP that is the equivalent of what is today known as the
modified duration of a cash-flow.
There are two key intuitions in the APP. The first one is that a fall of interest rates
incentivize in increase in the period of production. The second one is that a fall of interest
rates also incentivize more capital intense production. (Cachanosky & Lewin, 2014, 2016b;
Lewin & Cachanosky, 2017) show that these two intuitions can in fact be captured in a
financial framework and that the ABCT can be framed in financial terms. Finance provides a
well-known measure of the average period of a cash-flow, which is the Macaulay duration.
Cachanosky and Lewin show that under ceteris paribus, the cash-flow with a longer life has
a larger Macaulay duration. The second intuition requires transforming the usual free-cash-
flow (FCF) into its equivalent Economic Value Added (EVA®) representation.11 By doing
this, the cash-flow now has an explicit measurement of financial capital. Cachanosky and
Lewin show that, ceteris paribus, the cash-flow with a larger financial capital also has a
larger Macaulay duration.
10 This issue has been present in three capital debates since Böhm-Bawerk’s work to the Cambridge
controversy. See (Cohen, 2008, 2010; Cohen & Harcourt, 2003; Lewin & Cachanosky, n.d.).
11 On EVA® applications ot corporate finance see (Ehrbar, 1998; Stern, Shiely, & Ross, 2003; Young &
O’Byrne, 2000). For an application to economics and market process see (Cachanosky, 2017).

But this analysis has a dual result that coincides with Hick’s contribution. In both cases,
either longer or larger financial capital, these cash-flows also have a larger modified
duration, which is a measure of the present value sensitivity to changes in the interest
rate.12 This means that even though a fall in interest rates makes all present values
increase, those of cash-flow that are either longer or require a larger investment increase
more than shorter cash-flows and small projects. Then, modified duration is the financial
equivalent to Böhm-Bawerk’s APP.
This means that Wicksell Effect can actually be captured through the effects of monetary
policy on the present value of the cash-flows of different and competing investment
opportunities in the portfolio of investors. A reduction in interest rates makes the relative
price of longer and larger investment to increase with respect to shorter and smaller
projects. A reversion of the monetary policy produces the opposite movement in the
relative prices of these two projects which signals to investors that resources need to be
reallocated, which can be costly if investment is irreversible (Dixit & Pyndick, 1994).
Furthermore, (Cachanosky & Lewin, 2016a) show that in the years of low interest rates
prior to the 2008 crisis, economic profits as perceived by firms, is higher on larger firms
than on smaller firms. These empirical results match the Wicksell Effect in the ABCT.
4. Conclusions
12 In continuous time, Macualay duration and modified duration are equal.
