An essential assumption to reach this...</p>

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 investigate the interaction of regional population and employment in a simu1taneousmodel, allowing for interregional commuting. The proposed dynamic specificationdistinguishes between short-run and equilibrium adjustment effects and it encompassesthe lagged-adjustment specification that is...

We hypothesize that workers in high-unemployment...</p></a>

This paper examines the recruitment process of firms. We test whether firms search sequentially or non-sequentially using data compiled from filled vacancies. According to theory, in case of sequential hiring, the number of applicants is proportional to the number of employees hired, whereas in...

We study the employees' demand for hospital parking. We estimate the effect of the employees' parking price on demand using a difference-in-differences methodology. The deadweight loss generated by non-optimal pricing of parking is at least 9% of the hospitals' parking resource costs.

In the present study we carry out an analysis of speed fluctuations as a determinant of the quality of public transport. We do this by focusing on a special cause of unreliability: variations in weather conditions. We use hourly measured weather conditions. The panel data results imply that snow...

In Europe, company cars are offered by employers as fringe benefits to their employees at a lower price than employees pay in the car market, mainly due to favourable taxation of company cars. We analyse the welfare effects of favourable taxation of company cars for the Netherlands. The...
