Using administrative data on wealth, firm ownership structure, and migration in Sweden and Denmark, we document international migration patterns among the very wealthy, their impact on the economy, and how they respond to wealth taxation. We show that more than 20% of taxpayers liable to pay...

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...

This paper explores the optimal income tax treatment of couples. Each couple is modelled as a single agent supplying labor along two dimensions: primary-earner and secondary-earner labor supply. We consider fully general nonlinear income tax schedules which creates a multi-dimensional screening...

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...

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...

This paper investigates if the impact of children on the labor market trajectories of women relative to men child penalties can be explained by the biological links between mother and child. We estimate child penalties in biological and adoptive families using event studies around the arrival of...

This paper evaluates the tax treatment of married couples in OECD countries. While the existing literature has emphasized the relation between marginal taxes and hours of work, the novelty of our analysis is the incorporation of labor force participation responses. Indeed, the modern empirical...

The literature suggests that the concern for economic efficiency calls for individual-based taxation of married couples with a higher rate on the primary earner. This paper reconsiders the choice of tax unit in the Becker model of household production. Our aim is to study the robustness of...

We reconsider the result that efficient taxation involves a lower marginal tax on secondary earners than on primary earners. Introducing labor force participation responses into the analysis, we show that a second-earner tax allowance is better than selective marginal tax rates.

This paper presents evidence on taxable income responses using administrative data that link tax return information to detailed socioeconomic information for the entire Danish population over 25 years. The identifying variation is provided by a series of tax reforms that create large tax...
