We examine the effect of enforcing minimum quality standards (MQSs) on consumer health. In the late 1800s, the urban milk supply was regularly skimmed and diluted with water, but consumers could not easily determine its quality because dyes, caramel, and salt were added. To protect consumers,...

Recent studies based on 20th century US data conclude that abortion access raises children's average socioeconomic outcomes. We generalize a model of fertility, highlighting assumptions under which these abortion predictions can be reversed. Using 19th century abortion restrictions, we...

We re-characterize American slavery as inefficient, whereby emancipation generated substantial aggregate economic gains. Coercive labor markets were severely distorted, with the social marginal cost of labor substantially above its marginal benefit. Production during enslavement came at immense...

We analyze the effect of imposed benefit sanctions on the unemployment-to-employment transition of unemployed people entitled to unemployment compensation on the basis of register data from the German Federal Employment Agency. We combine propensity score matching with a discrete-time hazard...

We analyze the consequences of counseling provided to job seekers in a standard job search and matching model. It turns out that neglecting equilibrium effects induced by counseling can lead to wrong conclusions. In particular, counseling can increase steady state unemployment although counseled...

This paper uses a social experiment in labour market policy - providing early and intensive monitoring and programme participation in unemployment spells - to assess the nature of labour market policy effectiveness. The experiment was conducted in two counties in Denmark during the winter of...

This paper investigates the effects of five different vocational rehabilitation (VR) programs on the hazard rates into employment, disability and temporarily withdrawals from the labor market for persons who face severe problems in re-entering the labor market, mostly due to medical problems....

This paper implements a method to identify and estimate treatment effects in a dynamic setting where treatments may occur at any point in time. By relating the standard matching approach to the timing-of-events approach, it demonstrates that effects of the treatment on the treated at a given...

We analyse the effect of active labour-market programmes on the hazard rate into regular employment for newly arrived immigrants using the timing-of-events duration model. We take account of language course participation and progression in destination country language skills. We use rich...
