Abstract

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.

Abstract

This paper characterizes optimal unemployment insurance (UI) over the business cycle using a model of equilibrium unemployment in which jobs are rationed in recession. It offers a simple optimal UI formula that can be applied to a broad class of equilibrium unemployment models. In addition to the usual statistics (risk aversion and micro-elasticity of unemployment with respect to UI), a macro-elasticity appears in the formula to capture the macroeconomic impact of UI on unemployment. In a model with job rationing, the formula implies that optimal UI is countercyclical. This result arises because in recession, jobs are lacking irrespective of job search. Therefore (1) a higher aggregate search effort cannot reduce aggregate unemployment much; and (2) individual search effort creates a negative externality by reducing other jobseekers' probability of finding a job as in a rat race. Hence the social benefits of job search are low. In a calibrated model, optimal UI increases significantly in recession. This quantitative result holds whether the government adjusts the level or duration of benefits; whether it balances its budget each period or uses deficit spending.

Abstract

This paper analyzes the effects of top earnings tax rates on the international migration of football players in Europe. We construct a panel dataset of top earnings tax rates, football player careers, and club performances in the first leagues of 14 Western European countries since 1985. 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 develop a multinomial regression framework to exploit all sources of tax variation simultaneously. Our results show that (i) the overall location responses to the net-of-tax rate is positive and large, with an elasticity of the number of foreign players to the net-of-tax rate around one (and an elasticity of the number of domestic players around .15), (ii) location elasticities are even larger 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. Those results can be rationalized in a simple model of migration and taxation with rigid labor demand.

Abstract

We develop a theory of optimal unemployment insurance (UI) that accounts for workers' job-search behavior and firms' hiring behavior. The optimal replacement rate of UI is the conventional Baily [1978]-Chetty [2006a] rate, which solves the trade-off between insurance and job-search incentives, plus a correction term, which is positive when UI brings the labor market tightness closer to efficiency. For instance, when tightness is inefficiently low, optimal UI is more generous than the Baily-Chetty rate if UI raises tightness and less generous if UI lowers tightness. We propose empirical criteria to determine whether tightness is inefficiently high or low and whether UI raises or lowers tightness. The theory has implications for the cyclicality of optimal UI.
