February 2016
Motivation
Regional fiscal autonomy varies considerably across countries, e.g.,
I France, Japan, United Kingdom: regional entities do not set tax policyI Canada, Spain, Italy: regions have large tax autonomyI U.S. state tax autonomy is similar to the later group
What are the aggregate consequences of regional di↵erences in taxes?
I Misallocation logic suggests potentially negative e↵ects
F Restuccia and Rogerson (2008); Hsieh and Klenow (2009)
I This paper: quantify the aggregate e↵ects of dispersion in tax rates
across U.S. states
Background on the U.S. State Tax System
3 Major Sources of Tax Revenue used by the States (4% of U.S. GDP)
I Sales tax (47% of total state tax revenue in 2012) more
I Personal income tax (35%) more
I Corporate income tax (5%) more
State tax rates are heterogeneous
I 90-10 percentiles of state tax-rate distributions: rates revenue
F 7%-1.4% (sales)F 9.2%-0% (personal income)F 4.6%-0% (corporate)
Changes in state tax revenue are strongly correlated with changes in directexpenditures
I E.g., education, public welfare, hospitals, highways, police, natural resources,parks and recreation.
This Paper
1 Quantitative Geography Model with U.S. State Tax System
I States with heterogeneous fundamentals
F productivity, amenities, trade costs, factor shares, fixed factors,ownership rates
I Workers and firms sort across states according to idiosyncratic draws
I Firms are monopolistically competitive
I 3 major state taxes and federal transfers
F finance state spending which may be valued by workers and firms
2 Estimation
I Elasticities of worker and firm location with respect to taxes
F data on economic activity and 350 state tax changes over 1980-2010
I Fundamentals
F match distribution of employment, wages, and trade in 2007
3 Main Counterfactual
I Movement to harmonized state tax system keeping government spendingconstant through inter-state transfers

Implementing counterfactuals with respect to taxes requires:
I mapping from changes in fundamentals to changes in outcomes (standard)I mapping from changes in taxes to changes in adjusted fundamentals (specific
to our model)
Impact of Tax Dispersion on Worker Welfare
What is the e↵ect of eliminating dispersion in taxes {Tn} on worker welfare v keeping
{Gn} constant?
I Assume
F no trade frictions (⌧in = 1), perfect substitutes (� = 1), homogeneous firms("F= 1),
F no cross-state dispersion in income shares (�n = �) or in preferences forspending (↵W ,n = ↵W )

Eliminating dispersion in{Tn} while keeping spending constant increases (decreases)
worker welfare if corr⇣Z⇣n , (1� Tn)
⇣⌘
is low (high) enough
Intuition
I Workers gain from dispersion in state-specific appeals, {vn}I State-specific appeal depends on both taxes and fundamentals (through prices)I High correlation between keep rates and fundamentals implies high dispersion
Consider corr⇣Z⇣n , (1� Tn)
⇣⌘= 0. Eliminating dispersion increases welfare if
(1� ↵W ) (1� �) > 1/"W + ↵W
I Holds for ↵W , �, �W large, "W small
Impact of Tax Dispersion on Real Income
Eliminating dispersion in {Tn} while keeping spending constant:
I may increase or decrease aggregate real income depending on the joint distributionof Tn, un, and Gn
I increases it under perfect mobility ("W ! 1), no public goods (↵W = 0), and nodispersion in amenities (un = 0)
F In this case, the model is the same as Hsieh and Klenow (2009)
Intuition
I Real income maximized under no dispersion of MPL.I But labor mobility is a↵ected by compensating di↵erentials,
v = unG↵Wn ((1� Tn)(MPLn))1�↵W
Key Forces
Agglomeration
I Home market e↵ects due to trade costs (final consumption andintermediates): {"W , "F ,�, {�n}}
I Returns to public spending: {↵F ,n,↵W ,n,�F ,�W }
Congestion
I Fixed factor used in production (land and structures): {�n}I Dispersed ownership of fixed factors: {bn}
Heterogeneity in productivity, endowments, amenities, trade costs: {zn,Hn, un, ⌧in}
Data
Economic Activity
I Number of workers and establishments by state (County Business Patterns)I Total sales (Economic Census)I Factor payments, value added (BEA)I Trade flows (Commodity Flow Survey)

Welfare gains decrease as we increase the cross-state correlation between initialkeep-tax rates and the total number of workers
Whether a harmonized tax system that keeps government spending constant issuperior to an observed spatial tax distribution depends on the specific country inquestion.

Conclusion
We study the e↵ects of the state tax distribution on welfare and the distribution ofeconomic activity in the U.S.

F Gains increase to 0.45% under progressive income taxes
I Doubling tax dispersion leads to welfare loss of 0.4%
