The probability of income loss depends on talent and effort. Effort has positive externalities and therefore individuals are awarded status in proportion to their perceived diligence. The social norm requires more effort from individuals perceived as more talented. But talent is private...

Based on a randomised experiment we estimate effects from notification to medical doctors of tighter monitoring of their medical certificates. Both time prescribed by the doctor certificates for sick leave (prescribed sick leave) and the impact on the length of the actual sickness absence...

This paper estimates the effects of early interventions in the Swedish sickness insurance system. The aim of the interventions is to screen and, further to, rehabilitate sick listed individuals. We find that the early interventions – in contrast to what is expected – increase the inflow into...

This paper considers treatment evaluation in a discrete time setting in which treatment could start at any point in time. A typical application is an active labor market policy program which could start after any elapsed unemployment duration. It is shown that various average effects on survival...

This paper discusses the evaluation problem using observational data when the timing of treatment is an outcome of a stochastic process. We show that, without additional assumptions, it is not possible to estimate the average treatment effect and treatment on the treated. It is, however,...

This paper provides new estimates of the medium and long-term impacts of Head Start on the health and behavioral problems of its participants. We identify these impacts using discontinuities in the probability of participation induced by program eligibility rules. Our strategy allows us to...

The Non-financial (Notional) Defined Contribution (NDC) PAYGO pension scheme is a recent innovation and its generic dimensions have not previously been explored in a coherent context. This paper does this. It derives and analyzes the demographic, economic and distributional properties of NDC....

In this paper, we study the short-run effect of salary receipt on mortality among Swedish public sector employees. By using data on variation in pay-days across work-places, we completely control for mortality patterns related to, for example, public holidays and other special days or events...
