September 2019Use It or Lose It: Efficiency Gains from Wealth Taxation
with Fatih Guvenen, Burhanettin Kuruscu, Sergio Ocampo-Diaz, Daphne Chen: w26284
How does wealth taxation differ from capital income taxation? When the return on investment is equal across individuals, a well-known result is that the two tax systems are equivalent. Motivated by recent empirical evidence documenting persistent heterogeneity in rates of return across individuals, we revisit this question. With such heterogeneity, the two tax systems have opposite implications for both efficiency and inequality. Under capital income taxation, entrepreneurs who are more productive, and therefore generate more income, pay higher taxes. Under wealth taxation, entrepreneurs who have similar wealth levels pay similar taxes regardless of their productivity, which expands the tax base, shifts the tax burden toward unproductive entrepreneurs, and raises the savings rate of produc...
July 2017Hours, Occupations, and Gender Differences in Labor Market Outcomes
with Andrés Erosa, Luisa Fuster, Richard Rogerson: w23636
We document a robust negative relationship between the log of mean annual hours in an occupation and the standard deviation of log annual hours within that occupation. We develop a unified model of occupational choice and labor supply that features heterogeneity across occupations in the return to working additional hours and show that it can match the key features of the data both qualitatively and quantitatively. We use the model to shed light on gender differences in labor market outcomes that arise because of gender asymmetries in home production responsibilities. Our model generates large gender gaps in hours of work, occupational choices, and wages. In particular, an exogenous difference in time devoted to home production of ten hours per week increases the observed gender wage gap b...
