Tax Competition and Employment

May 26, 2023
Working Paper

We examine how exposure to international tax competition affects domestic firms’ employment. Consistent with prior work, we find evidence that reductions in foreign tax rates affect the domestic competitive environment via increases in import competition and investment in foreign-owned subsidiaries.

Does the Tax System Favor Superstar Firms?

January 26, 2023
Working Paper

Influential recent research finds that economic activity is increasingly concentrated in large, highly profitable "superstar firms." The causes and consequences of the rise of superstar firms are the subjects of intense debate among academics, policymakers, and others. Acting on concerns that superstar firms have tax advantages relative to other firms, policymakers are increasingly designing and enacting additional taxes that target superstar firms. We examine the validity of the underlying assumption that the tax system favors superstar firms, using both forward-looking and backward-looking measures of firms’ tax burdens. Across multiple specifications, we find little empirical support for the idea that superstar firms are tax advantaged. Overall, the evidence suggests that tax advantages generally are not an important factor in explaining which firms rise to superstar status, nor do they appear to be an important factor in sustaining their dominance.

Federal Corporate Tax Enforcement and Local Business Activity

January 11, 2023
Working Paper

We examine the consequences of federal corporate tax enforcement for local business activity, and in particular whether (i) these consequences vary across regions and firms and (ii) tax enforcement has spillover effects. Exploiting geographic variation in exposure to firms of different sizes and variation in tax return audit rates across firm size groups, we first document that corporate tax enforcement is negatively associated with regional business activity. More interestingly, we document substantial heterogeneity in this association. We find that tax enforcement has spillover effects, as indicated by a stronger negative effect in urban areas and in regions with more vertically-related business activity. The negative association is also greater in regions in which firms likely face higher compliance costs and have less access to external capital. Our findings collectively suggest that the effects of tax enforcement on business activity are highly heterogeneous, which should be of interest to academics and policymakers. More

Investor Perceptions of the Book Minimum Tax

September 28, 2022
Working Paper

The Inflation Reduction Act establishes a new 15 percent corporate minimum tax on large U.S. corporations’ adjusted financial accounting income. While the minimum tax is estimated to raise $222 billion over 10 years, critics fear firms will manipulate their accounting earnings to reduce their tax liabilities, resulting in less revenue raised. Further, given the current political environment future legislatures could gut the tax, further eroding estimated tax revenues. Using an event study, we examine the extent to which investors believe this tax will reduce firm value. We examine stock market reactions around key legislative developments leading to the enactment of the book minimum tax. Our findings show targeted firms experience significantly lower stock returns than non-targeted firms during the enactment process (about 1.4 to 1.8 percent). In aggregate, our findings are consistent with the Joint Committee on Taxation’s revenue estimates. In cross-sectional tests, we do not observe that the firms most likely to avoid the tax via earnings management experience more positive returns, suggesting the market does not anticipate firms avoiding the tax via earnings management. Overall, our results suggest investors do not expect firms to largely avoid this tax. Instead, they expect a significant portion of the corporate minimum tax will be remitted by firms and borne by shareholders.   More

Tax Planning Knowledge Diffusion via the Labor Market

May 12, 2021
Working Paper

This paper examines the extent to which the labor market facilitates the diffusion of tax planning knowledge across firms. Using a novel dataset of tax department employee movements between S&P 1500 firms, the researchers find that firms experience an increase in their tax planning after hiring a tax employee from a tax aggressive firm. This finding is robust to various research designs and specifications. More
