This working paper presents Chapter 7 of a book to be published for the National Bureau of Economic Research by the University of Chicago Press. The point of the book is to compare taxes on income from capital in four countries,accounting for corporate, personal, and property taxes, and...

We find that sin good purchases are highly concentrated with 10% of households paying more than 80% of taxes on alcohol and cigarettes. Total sin tax burdens are poorly explained by demographics (including income), but are well explained by eight household clusters defined by purchasing...

This paper presents a test for the existence of debt clienteles in which the latter are represented by progressive personal tax brackets. The test generates some evidence consistent with the implication of debt clientele theory that, over time, firms' debt ratios should vary with the relative...

We study optimal corporate taxation when firms are financially constrained. We describe a corporate taxation principle: taxes should be levied on unconstrained firms, which value resources inside the firm less than constrained firms. Under complete information, this principle completely...

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...

This paper investigates the 2013 three-fold increase in the French dividend tax rate. Using administrative data covering the universe of firms from 2008-2017 and a quasi-experimental setting, we find that firms swiftly cut dividend payments and used this tax-induced increase in liquidity to...

Tax harmonization entails a uniform rate that may not suit all governments. Harmonization can advance collective governmental objectives only if the standard deviation of tax rates is less than the average downward effect of tax competition on rates. Since an efficient harmonized tax rate undoes...

This paper derives optimal income tax formulas using compensated and uncompensated elasticities of earnings with respect to tax rates. A simple formula for the high income optimal tax rate is obtained as a function of these elasticities and the thickness of the top tail of the income...

A central tax policy parameter that has recently received much attention, but about which there is substantial uncertainty, is the overall elasticity of taxable income. We provide new estimates of this elasticity which address identification problems with previous work, by exploiting a long...

We characterize optimal policies in a multidimensional nonlinear taxation model with bunching. We develop an empirically relevant model with cognitive and manual skills, firm heterogeneity, and labor market sorting. The analysis of optimal policy is based on two main results. We first derive an...
