Despite considerable gender convergence over time, substantial gender inequality persists in all countries. Using Danish administrative data from 1980-2013 and an event study approach, we show that most of the remaining gender inequality in earnings is due to children. The arrival of children creates a gender gap in earnings of around 20% in the long run, driven in roughly equal proportions by labor force participation, hours of work, and wage rates. Underlying these "child penalties", we find clear dynamic impacts on occupation, promotion to manager, sector, and the family friendliness of the firm for women relative to men. Based on a dynamic decomposition framework, we show that the fraction of gender inequality caused by child penalties has increased dramatically over time, from about 40% in 1980 to about 80%in 2013. As a possible explanation for the persistence of child penalties, we show that they are transmitted through generations, from parents to daughters (but not sons), consistent with an influence of childhood environment in the formation of women's preferences over family and career.

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 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 set out a theoretical model of taxation and migration, which is tested 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.

Using Danish administrative data, we study the impacts of children on gender inequality in the labor market. The arrival of children creates a long-run gender gap in earnings of around 20 percent driven by hours worked, participation, and wage rates. We identify mechanisms driving these “child penalties” in terms of occupation, sector, and firm choices. We find that the fraction of gender inequality caused by child penalties has featured a dramatic increase over the last three to four decades. Finally, we show that child penalties are transmitted through generations, from parents to daughters, suggesting an influence of childhood environment on gender identity.

This paper provides a simple, yet robust framework to evaluate the time profile of benefits paid during an unemployment spell. We derive sufficient-statistics formulae capturing the marginal insurance value and incentive costs of unemployment benefits paid at different times during a spell. Our approach allows us to revisit separate arguments for inclining or declining profiles put forward in the theoretical literature and to identify welfare-improving changes in the benefit profile that account for all relevant arguments jointly. For the empirical implementation, we use administrative data on unemployment, linked to data on consumption, income and wealth in Sweden. First, we exploit duration-dependent kinks in the replacement rate and find that, if anything, the moral hazard cost of benefits is larger when paid earlier in the spell. Second, we find that the drop in consumption affecting the insurance value of benefits is large from the start of the spell, but further increases throughout the spell. In trading off insurance and incentives, our analysis suggests that the flat benefit profile in Sweden has been too generous overall. However, both from the insurance and the incentives side, we find no evidence to support the introduction of a declining tilt in the profile.Keywords: Unemployment, Dynamic Policy, Sufficient Statistics, Consumption Smoothing JEL codes: H20, J64 * We thank Tony Atkinson, Richard Blundell, Raj Chetty, Liran Einav, Hugo Hopenhayn, Philipp Kircher, Henrik Kleven, Alan Manning, Arash Nekoei, Nicola Pavoni, Torsten Persson, Jean-Marc Robin, Emmanuel Saez, Florian Scheuer, Robert Shimer, Frans Spinnewyn, Ivan Werning, Gabriel Zucman and seminar participants at the NBER PF Spring Meeting, SED Warsaw, EEA Mannheim, DIW Berlin, Kiel, Zurich, Helsinki, Stanford, Leuven, Uppsala, IIES, Yale, IFS, Wharton, Sciences Po, UCLA, Sussex, Berkeley, MIT, Columbia, LMU and LSE for helpful discussions and suggestions.

The impact of these adverse events is dynamic and so are the insurance value and incentive cost of social protection against these events. As a consequence, the design of social insurance policies tends to be dynamic as well, specifying a schedule of benefits and taxes that are time-dependent. In the context of unemployment insurance (UI), the UI policy specifies a full benefit profile designed to balance incentives and insurance throughout the unemployment spell. Solving this dynamic problem can prove daunting, especially when adding important features of unemployment dynamics involving selection and non-stationarities. Indeed, there seems to be little conse...
