We exploit the introduction of sulfa drugs in 1937 to identify the causal impact of exposure to pneumonia in infancy on later life well-being and productivity in the United States. Using census data from 1980-2000, we find that cohorts born after the introduction of sulfa experienced increases...

This paper provides a new way of analyzing tenure profiles in wages, by modelling simultaneously the evolution of wages and the distribution of tenures. We develop a theoretical model based on efficient bargaining, where both log outside wage and log wage in the current job follow a random walk,...

This paper presents results on the effect of formal life-long learning on the decision to retire early. Specifically, I estimate an Option Value model based on individual employer-employee longitudinal data including comprehensive government co-sponsored training records dating back more than 30...

We refine modelling of the radical innovation decision in this paper by extending real option theory to include non-marginal stochastic jump processes. From the model analytics we determine that the average magnitude and frequency of non-marginal stochastic jump processes are the most important...

In "new" new international trade theory, whether firms export or not are determined by their productivity. These models assume that firms enter a market to find their productivity levels revealed to them as in a lottery. In this paper we propose an alternative way to model whether firms export...

Many Belgian retire well before the statutory retirement age. Numerous exit routes from the labor force can be identified: old-age pensions, conventional early retirement, disability insurance, and unemployment insurance are the most prominent ones. We analyze the retirement decision of Belgian...

Macroeconomic shocks and labour-market institutions jointly determine employment growth and economic performance. The effect of shocks depends on the nature of these intitutions and the effect of institutional change depends on the macroeconomic environment. It follows that a given set of...
