A comparison of hazard rates of duration outcomes before and after policy changes is hampered by non-identification if there is unobserved heteogeneity in the effects and no model structure is imposed. We develop a discontinuity approach that overcomes this by exploiting variation in the moment...

Causal effects of a policy change on hazard rates of a duration outcome variable are not identified from a comparison of spells before and after the policy change if there is unobserved heterogeneity in the effects and no model structure is imposed. We develop a discontinuity approach that...

Positive assortative matching refers to the tendency of individuals with similar characteristics to form partnerships. Measuring the extent to which assortative matching differs between two economies is challenging when the marginal distributions of the characteristic along which sorting takes...

In this paper we look at lifetime inequality to address two main questions: How well does a modern tax system, based on annual information, target lifetime inequality? What aspects of the tranfser system are most progressive from a lifetime perspective? To answer to these questions it is crucial...

We consider the impact of tax credits and income support programs on female education choice, employment, hours and human capital accumulation over the life-cycle. We analyse both the short run incentive effects and the longer run implications of such programs. By allowing for risk aversion and...

Personal taxes and benefits affect the incentive to work over the lifecycle by altering income-age profiles, insuring against adverse shocks, and changing the returns to human capital. Previous work investigating the impact of taxes and benefits on work incentives has tended to ignore these...
