We use micro data from the U.S. Internal Revenue Service to document how households' tax liabilities vary with income, marital status and the number of dependents. We report facts on the distributions of average and marginal taxes, properties of the joint distributions of taxes paid and income,...

We examine the extent to which taxes on corporate income are directly shifted onto the workforce. We use data on 55,082 companies located in nine European countries over the period 1996-2003. We identify this direct shifting through cross-company variation in tax liabilities, conditional on...

By inverting Saez (2002)'s model of optimal income taxation, we characterize the redistributive preferences of the Irish government between 1987 and 2005. The (marginal) social welfare function revealed by this approach is consistently comparable over time and show great stability despite...

The public finance literature demonstrates the equivalence between consumption and labor-income (wage) taxes. We introduce an experimental paradigm in which individuals make real labor-leisure choices and spend their earned income on real goods. We use this paradigm to test whether a...

We estimate the responses of gross labor earnings with respect to marginal and average net-of-tax rates in France over the period 2003-2006. We exploit a series of reforms to the income-tax and the payroll-tax schedules that affect individuals who earn less than twice the minimum wage. Our...

We study optimal tax and educational policies in a dynamic private information economy, in which ex-ante heterogeneous individuals make an educational investment early in their life and face a stochastic wage distribution. We characterize labor and education wedges in this setting analytically...

Given its significance in practice, piecewise linear taxation has received relatively little attention in the literature. This paper offers a simple and transparent analysis of its main characteristics. We fully characterize optimal tax parameters for the cases in which budget sets are convex...

Based on well-known evidence on labor supply elasticities, several authors have concluded that women should be taxed at lower rates than men. We evaluate the quantitative implications of taxing women at a lower rate than men. Relative to the current system of taxation, setting a proportional tax...

This paper presents estimates of individuals' responses in hourly wages to changes in marginal tax rates. Estimates based on register panel data of Swedish households covering the period 1992 to 2007 produce significant but relatively small net-of-tax rate elasticities. The results vary with...

Income mobility is often thought to equalize permanent incomes and thereby to improve social welfare. The welfare analysis of mobility often fails, however, to account for the cost of the variability of periodic incomes around permanent incomes. This paper assesses the net welfare benefit of...
