This paper computes the optimal progressivity of the income tax code in a dynamic general equilibrium model with household heterogeneity in which uninsurable labour productivity risk gives rise to a nontrivial income and wealth distribution. A progressive tax system serves as a partial...

In this paper we quantitatively characterize the optimal capital and labor income tax in an overlapping generations model with idiosyncratic, uninsurable income shocks, where households also differ permanently with respect to their ability to generate income. The welfare criterion we employ is...

The Paper investigates the relationship of work and family life in Britain. Using hazard regression techniques we estimate a five-equation model, which includes birth events, union formation, union dissolution, employment and non-employment events. The model allows for unobserved heterogeneity...

What would be the aggregate effects of adopting a more generous and universal childcare subsidy program in the U.S.? We answer this question in a life-cycle equilibrium model with heterogeneous married and single households with three key features: (i) joint labor-supply of married households...

Changing social norms, as reflected in the interactions between spouses, are hypothesized to affect the employment rates of married women. A model is built in order to estimate this effect, in which the employment of married men and women is the outcome of an internal household game. The type of...

This paper analyzes the problem of optimal taxation of top labour incomes. We develop a model where top incomes respond to marginal tax rates through three channels: (1) the standard supply-side channel through reduced economic activity, (2) the tax avoidance channel, (3) the compensation...

What structure of income taxation maximizes the social benefits of redistribution while minimizing the social harm associated with distorting the allocation of labor input? Many authors have advocated scrapping the current tax system, which redistributes primarily via marginal tax rates that...

Social insurance for the elderly is judged responsible for the widely observed trend towards early retirement. In a world of laissez-faire or in a first-best setting, there would be no such trend. However, when first-best instruments are not available, because health and productivity are not...
