Corporate tax cuts and the decline of the manufacturing labor share
We document a strong empirical connection between corporate taxation and the manufacturing labor share, both in the US and across OECD countries. Our estimates associate 30 percent to 60 percent of the observed decline in labor shares with the fall in corporate taxation. Using an equilibrium model of an industry where firms differ in their capital intensities, we show that lower corporate tax rates reduce the labor share by raising the market share of capital-intensive firms. The tax elasticity of the labor share depends on the joint distribution of labor intensities and value added at the ...

Tax Policy Endogeneity: Evidence from R&D Tax Credits
Because policymakers may consider the state of the economy when setting taxes, endogeneity bias can arise in regression models that estimate relationships between economic variables and taxes. This paper quantifies the policy endogeneity bias and estimates the impact of R&D tax incentives on R&D expenditures at the U.S. state level. Identifying tax variation comes from changes in federal corporate tax laws that heterogeneously impact state-level R&D tax incentives due to the simultaneity of state and federal corporate taxes. With this exogenous variation, my preferred estimates indicate a 1 ...

International Transfer Pricing and Tax Avoidance : Evidence from Linked Trade-Tax Statistics in the UK
This paper employs unique data on export transactions and corporate tax returns of UK multinational firms and finds that firms manipulate their transfer prices to shift profits to lower-taxed destinations. It uncovers three new findings on tax-motivated transfer mispricing in real goods. First, transfer mispricing increases substantially when taxation of foreign profits changes from a worldwide to a territorial approach in the UK, with multinationals shifting more profits into low-tax jurisdictions. Second, transfer mispricing increases with a firm's R&D intensity. Third, tax-motivated ...

The Effect of Bank Monitoring on Loan Repayment
Monitoring is one of the main activities explaining the existence of banks, yet empirical evidence about its effect on loan outcomes is scant. Using granular loan-level information from the Italian Credit Register, we build a novel measure of bank monitoring based on banks’ requests for information on their existing borrowers and we investigate the effect of bank monitoring on loan repayment. We perform a causal analysis exploiting changes in the regional corporate tax rate as a source of exogenous variation in bank monitoring. Our identification strategy is supported by a theoretical model ...

The Welfare Costs of Misaligned Incentives: Energy Inefficiency and the Principal-Agent Problem
In many settings, misaligned incentives and inadequate monitoring lead employees to take self-interested actions contrary to their employer's wishes, giving rise to the classic principal-agent problem. In this paper, I identify and quantify the costs of misaligned incentives in the context of an energy efficiency appliance replacement program. I show that contractors (agents) hired by the electric utility (the principal) increase their compensation by intentionally misreporting program data to deliberately authorize replacement of non-qualified refrigerators. I provide empirical estimates of ...

Consumption, Wealth, and Income Inequality: A Tale of Tails
We provide evidence that the distributions of consumption, labor income, wealth, and capital income exhibit asymptotic power-law behavior with a strict ranking of upper tail inequality, in that order, from the least to the most unequal. We show analytically and quantitatively that the canonical heterogeneous-agent model cannot replicate the proper ranking and magnitudes of these four tails simultaneously. Mechanisms addressing the wealth concentration puzzle in these models through return heterogeneity lead to a mirror consumption concentration puzzle. We match the cross-sectional data on ...

The Dynamic Effects of Personal and Corporate Income Tax Changes in the United States: Reply to Jentsch and Lunsford
In this reply to a comment by Jentsch and Lunsford, we show that, when focusing on the relevant impulse responses, the evidence for economic and statistically significant macroeconomic effects of tax changes in Mertens and Ravn (2013) remains present for a range of asymptotically valid inference methods.

Global tax policy and the synchronization of business cycles
Using a 30-year panel of quarterly GDP ?uctuations from of a broad set of countries, we demonstrate that the signing of a bilateral tax treaty increases the comovement of treaty partners' business cycles by 1/2 a standard deviation. This e?ect of ?scal policy is as large as the e?ect of trade linkages on comovement, and stronger than the e?ects of several other common ?nancial and investment linkages. We also show that bilateral tax treaties increase comovement in shocks to nations? GDP trends, demonstrating the permanent e?ects of coordination on ?scal policy rules. We estimate trend and ...

The Role of Transfer Prices in Profit-Shifting by U.S. Multinational Firms : Evidence from the 2004 Homeland Investment Act
Using unique transaction-level microdata, this paper documents profit-shifting behavior by U.S. multinational firms via the strategic transfer pricing of intra-firm trade. A simple model reveals how differences in tax rates, both the corporate tax rates across countries and the dividend repatriation tax rate over time, affect the worldwide profit-maximizing transfer-prices set by firms for intra-firm exports and imports. I test the predictions of the model in the context of the 2004 Homeland Investment Act (HIA), a one-time tax repatriation holiday which generated a discreet change in the ...

Corporate income tax, legal form of organization, and employment
We adopt a dynamic stochastic occupational choice model with heterogeneous agents and evaluate the impact of a potential reduction in the corporate income tax on employment. We show that a reduction in corporate income tax leads to moderate job creation. In the extreme case, the elimination of the corporate income tax would reduce the non-employed population by 5.4 percent. In the model, a reduction in the corporate income tax creates jobs through two channels, one from new entry firms and one from existing firms changing their form of legal organization. In particular, the latter accounts ...
