Studies on the determinants of the demand for higher education typically emphasizethe relevance of socio-economic factors, but leave the spatial dimensions of the prospectivestudents’ university choices largely unexplored. In this study, we investigate the determinantsof university entrance...

We develop a model of an economy with several regions, which differ in scale. Within each region, workers have to search for a job-type that matches their skill. They face a trade-off between match quality and the cost of extended search. This trade-off differs between regions, because search is...

Based on micro-data on individual workers for the period 2000-2005, we show that wage differentials in the Netherlands are small but present. A large part of these differentials can be attributed to individual characteristics of workers. Remaining effects are partially explained by variations in...

We hypothesize, and test for, a negative effect of the length of the commute on worker’s productivity, by examining whether the commute has a positive effect on worker’s absenteeism. Our estimates for Germany indicate that commuting distance induces absenteeism with an elasticity of about...

We consider a model for a serial supply chain in which production, inventory, and transportation decisions are integrated, in the presence of production capacities and for different transportation cost functions. The model we study is a generalization of the traditional single-item economic...

In this paper we describe a Sequential Importance Sampling (SIS) procedure for counting the number of vertex covers in general graphs. The performance of SIS depends heavily on how close the SIS proposal distribution is to a uniform one over a suitably restricted set. The proposed algorithm...

This paper proposes that risk aversion encourages individuals to invest in balancedskill profiles, making them more likely to become entrepreneurs. By not havingtaken this possible linkage into account, previous research has underestimated the impactsboth of risk aversion and balanced skills on...
