We determine workforce composition and wages in firms in the presence of productivity spill-overs between co-workers. In equilibrium, workers’ wages depend on the production structure of firms, own group size, and aggregate workforce composition in the firm. We estimate the wage effects of...

Sick workers in many countries receive sick pay during their illness-related absences from the workplace. In several countries, the social security system insures firms against their workers’ sickness absences. However, this insurance may create moral hazard problems for firms, leading to the...

Does the supply of a welfare state create its own demand? Many economic scholars studying welfare arrangements refer to Say’s law and insinuate a self-destructive welfare state. However, little is known about the empirical validity of these assumptions and hypotheses. We study the dynamic...

This paper develops a new equilibrium model of two-sided search where agents have multiple attributes and general payoff functions. The model can be applied to several substantive issues. Here we use it to provide a novel understanding of the separate effects of equal opportunities for women in...

We use unique administrative data from a leading Italian University to estimate whether the use of admission tests and conditional progression schemes are effective strategies to select high-performing students. Previous work has mainly focused on the effect of selectivity policies on widening...

Using data from the Health and Retirement Study (HRS), we make two contributions to the literature on end-of-life transfers. First, we show that unequal bequests are much more common than generally recognized, with one-third of parents with wills planning to divide their estates unequally among...

We estimate the effect of binge drinking on accident and emergency attendances, road accidents, arrests, and the number of police officers on duty using a variety of unique data from Britain and a two-sample minimum distance estimation procedure. Our estimates, which reveal sizeable effects of...
