"An NBER digest for this paper is available.This paper analyzes the effects of top earnings tax rates on the international migration of top football players in Europe. We construct a panel data set of top earnings tax rates, football player careers, and club performances in the first leagues of 14 European countries since 1980. We identify the effects of top earnings tax rates on migration using a number of tax and institutional changes: (a) the 1995 Bosman ruling which liberalized the European football market, (b) top tax rate reforms within countries, and (c) special tax schemes offering preferential tax rates to immigrant football players. We start by presenting reduced-form graphical evidence showing large and compelling migration responses to country-specific tax reforms and labor market regulation. We then set out a theoretical model of taxation and migration, which is structurally estimated using all sources of tax variation simultaneously. Our results show that (i) the overall location elasticity with respect to the net-of-tax rate is positive and large, (ii) location elasticities are extremely large at the top of the ability distribution but negative at the bottom due to ability sorting effects, and (iii) cross-tax effects of foreign players on domestic players (and vice versa) are negative and quite strong due to displacement effects. Finally, we estimate tax revenue maximizing rates and draw policy conclusions"--National Bureau of Economic Research web site

We analyze the effects of top tax rates on international migration of football players in 14 European countries since 1985. Both country case studies and multinomial regressions show evidence of strong mobility responses to tax rates, with an elasticity of the number of foreign (domestic) players to the net-of-tax rate around one (around 0.15). We also find evidence of sorting effects (low taxes attract highability players who displace low-ability players) and displacement effects (low taxes on foreigners displace domestic players). Those results can be rationalized in a simple model of migration and taxation with rigid labor demand. (JEL F22, H24, H31, J44, J61, L83)

We develop an agency model explaining why third‐party information reporting by firms makes tax enforcement successful. While third‐party reporting would be ineffective with frictionless collusion between firms and employees, collusive evasion is impossible to sustain in firms with many employees and accurate business records as any single employee may reveal evasion. We embed our agency model into a macro model where the number of employees grows with development, showing that the tax take evolves as an S‐shape driven by changes in third‐party information. We show that our model is consistent with a set of stylized facts on taxation and development.

This paper estimates the welfare and distributional impact of two types of welfare reform in 14 member countries of the European Union. The reforms are revenue neutral and ?nanced by an overall and uniform increase in marginal tax rates on earnings. The ?rst reform distributes the additional tax revenue uniformly to everybody (traditional welfare) while the second reform distributes tax proceeds uniformly to workers only (in-work bene?t). We build a simple model of labor supply encompassing responses to taxes and transfers along both the intensive and extensive margin. We then use EUROMOD to describe current welfare and tax systems in all European Union countries (except Sweden) and use calibrated labor supply elasticities along the intensive and extensive margins to analyze the e?ects of the two welfare reforms. We quantify the equity-e?ciency trade-o? for a range of elasticity parameters. In most countries, because of the large existing welfare programs with high phase-out rates, the uniform redistribution policy is, in general, undesirable unless the redistributive tastes of the government are extreme. The in-work bene?t reform, on the other hand, is desirable in a very wide set of cases. We discuss the practical policy implications for European welfare policy.

This paper estimates the welfare and distributional impact of two types of welfare reform in the 15 (pre-enlargement) member countries of the European Union. The reforms are revenue neutral and financed by an overall and uniform increase in marginal tax rates on earnings. The first reform distributes the additional tax revenue uniformly to everybody (traditional welfare) while the second reform distributes tax proceeds uniformly to workers only (in-work benefit). We build a simple model of labor supply encompassing responses to taxes and transfers along both the intensive and extensive margin. We then use EUROMOD to describe current welfare and tax systems in European Union countries and use calibrated labor supply elasticities along the intensive and extensive margins to analyze the effects of the two welfare reforms. We quantify the equity-efficiency trade-off for a range of elasticity parameters. In most countries, because of large existing welfare programs with high phaseout rates, the uniform redistribution policy is undesirable unless the redistributive tastes of the government are extreme. The in-work benefit reform, on the other hand, is desirable in a very wide set of cases. We discuss the practical policy implications for European welfare policy.
