This paper analyses the welfare effects of two policies directed at the security of energy supply: investments in strategic petroleum reserves and a cap on the production of gas from the largest Dutch gas field. Market failures can justify such policies, in particular failure of individual...

Countries in a monetary union can adjust to shocks either through internal or external mechanisms. We quantitatively assess for the European Union a number of relevant mechanisms suggested by Mundell's optimal currency area theory, and compare them to the United States. For this purpose, we...

Banks play a central role in the functioning of the economy. Not only do they allocate financial resources, they also collectively create money in the process of granting loans. In this way, they have a considerable impact on the type of activities that are financed in society. During the...

This paper develops a model of search on the labour market with training. The model reveals how the tax system can restore the social optimum if the Hosio s condition is not satisfied in the private equilibrium. Furthermore, the effects are explored of a second-best reform from average to...

This paper analyzes the design of optimal unemployment insurance in a search equilibrium framework where search effort among the unemployed is not perfectly observable. We examine to what extent the optimal policy involves monitoring of search effort and benefit sanctions if observed search is...

This paper presents the results of an experimental study on unemployment benefit sanctions. The experimental set-up allows us to distinguish between the effect of benefit sanctions once they are imposed (the ex post effect) and the effect that unemployed want to avoid getting a benefit sanction...

We present a theoretical and empirical analysis of different types of active labor market policies (ALMP). In our empirical analysis we use data on 20 OECD countries covering the time period 1985-1999. We find that labor market training is the most effective program to bring down unemployment....

We model how unemployment benefit sanctions - benefit reductions that are imposed if unemployed do not comply with job search guidelines - affect unemployment. In our analysis we find that not only micro effects concerning the behavior of individual unemployed workers are relevant, but also...

This paper presents a theory and an empirical investigation on cyclical fluctuations in workplace accidents. The theory is based on the idea that reporting an accident dents the reputation of a worker and raises the probability that he is fired. Therefore a country with a high or an increasing...
