There is often a gap between the prescriptions of an "optimal" tax system and actual tax systems, some of which can be neither efficient economically nor efficient at redistributing income. With a focus on personal income taxes, this paper reviews the political economics literature on tax...

We study how the market for innovation affects enforcement of patent rights. Conventional wisdom associates the gains from trade with comparative advantage in manufacturing or marketing. We show that these gains imply that patent transactions should increase litigation risk. We identify a new...

The present study provides estimates of the Effective Marginal Tax Rates (EMTRs) for a sample of 17 OECD countries and 11 manufacturing sectors in a single framework encompassing capital, labour and energy taxes. Our cross-country/cross-sector approach allows us comparing the incentives provided...

Intertemporal shifting of wage income takes place when income earned in one tax year is paid out in another tax year in order to save taxes. Shifting has implications for the evaluation of the distortionary and distributional effects of taxes and may cause serious bias in empirical estimates of...

This paper documents the magnitude, pattern, and evolution of lifetime earnings inequality in Germany. Based on a large sample of earnings biographies from social security records, we show that the intra-generational distribution of lifetime earnings of male workers has a Gini coefficient around...

In this paper we argue that very high marginal labor income tax rates are an effective tool for social insurance even when households have preferences with high labor supply elasticity, make dynamic savings decisions, and policies have general equilibrium effects. To make this point we construct...

A worker can contribute pre-tax dollars to a private pension plan. Under a progressive tax, this feature reduces income taxes. Ippolito (1986} argues that an individual in 1979 can reduce lifetime taxes by 20%. We re-examine his analysis using the complete time-series of US income tax history...

In October 2007 France introduced an exemption on the income tax and social security contributions that applied to wages received for hours worked overtime. The goal of the policy was to increase the number of hours worked. This article shows that this reform has had no significant impact on...

This paper introduces a static structural model of hours of market labor supply, time spent on child care and other domestic work, and bought in child care for married or cohabiting mothers with pre-school age children. The father's behavior is taken as given. The main goal is to analyze the...

This paper presents for the .rst time the properties of optimal piece-wise linear tax systems for two-earner households, based on joint and individual incomes respectively. A key contribution is the analysis of the interaction of second earner wage di¤erences, variation in prices of bought-in...
