Working Paper
Tax Heterogeneity and Misallocation
Companies face different effective marginal tax rates on their income. This can be detrimental to allocative efficiency unless taxes offset other distortions in the economy. This paper estimates the effect of tax rate heterogeneity on aggregate productivity in distorted economies with multiple frictions. Using firm-level balance-sheet data and estimates of marginal tax rates, we find that tax heterogeneity reduces total factor productivity by about 3 percent. Our findings highlight the positive correlation between marginal tax rates and other distortions to capital and especially labor. This ...

Do Higher Markups Lower Labor’s Share of Income?
Higher price markups are typically associated with larger profits at the expense of labor's share of income. In this Economic Commentary, we challenge this view. The key to our argument is the reallocation of market shares toward labor-intensive firms, a reallocation caused by an increase in the prices of capital goods as a result of higher markups.

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 ...

Racial Differences in Returns on Business Ownership
In this Commentary, we document entrepreneurial income and investments for households of different racial backgrounds and provide estimates of investment yields. We find that an average Black household engaged in entrepreneurial activity has a higher rate of return on its business followed by Hispanic households and white households, a circumstance which makes low entrepreneurship rates among Black and Hispanic communities appear all the more puzzling.

Accounting for Wealth Concentration in the United States
We assess the empirical relevance of different macroeconomic modeling approaches to wealth concentration, using the joint distribution of earnings, capital income and net worth in combination with an OLG model of household heterogeneity. We find large earnings disparities to be the primary source of US wealth concentration. This reflects the fact that labor income, from salaries but also from entrepreneurship, is a major income source for top income and wealth groups in the data. Bequests and differences in rates of return on capital together explain about half the holdings of the wealthiest ...

Labor Substitutability among Schooling Groups
Knowing the degree of substitutability between schooling groups is essential to understanding the role of human capital in income differences and to assessing the economic impact of such policies as schooling subsidies, immigration systems, or redistributive taxes. We derive a lower bound for the substitutability required for worldwide growth in real GDP from 1960 to 2010 to be consistent with a stable wage premium for schooling despite the rapid growth in schooling, assuming no exogenous worldwide regress in the technology frontier for workers with only primary schooling. That lower bound ...
