We analyze long-run scenarios for the European natural gas markets in a model, NATGAS, that explicitly includes both resource constraints and producers’ market power. Europa wordt geconfronteerd met afnemende eigen aardgasvoorraden, met name in de van oudsher grote producenten het Verenigd...

Inspectors from the Dutch Inspectorate of Education inspect primary schools, write inspection reports on each inspected school, and make recommendations as to how each school can improve. We test whether these inspections result in better school performance. Using a fixed-effects model, we...

We construct a model for differentiated Cournot competition between service-based and infrastructure-based firms, out of which one infrastructure-based firm (the incumbent) supplies to the service-based firms. We seek for and compare the socially optimal and the incumbent’s profit maximizing...

Using a simple production game, we investigate whether public firms perform better when they increase the power of their workers’ incentive schemes. In a laboratory experiment, subjects choose between a ‘public firm’ and a ‘private firm’ with team and individual incentives,...

Education has always been regarded as a national matter. According to the subsidiarity principle power may only be shifted to a higher level of coordination when solid arguments exist that this will improve welfare. This paper aims at answering the question if these arguments exist. We find no...

We use the dynamic stochastic general equilibrium (DSGE) model of Altig et al. (2005) to analyse the resilience of an economy in the face of external shocks. The term resilience refers to the ability of an economy to prosper in the face of shocks. The Altig et al. model was chosen because it...

We analyse the interplay between investigation policies, deterrence and desistance in a model where a competition authority monitors multiple sectors and faces a budget constraint that prevents it from deterring cartels in all sectors simultaneously. Most studies of competition law enforcement...

Housing markets may significantly affect the relationship between regional population and employment, if housing supply is not fully accommodative to demand. We analyse the relationships between housing supply, regional population and employment empirically in a three-equation dynamic model....

Countries invest in international infrastructure in an effort to attract firms. Acquiring the position of a hub would make this effort successful. We use a model of international trade with monopolistic competition, increasing returns to scale and transport costs to analyse policy competition...

This paper analyses the relative performance and selection behaviour of not-for-profit (NFP) job training service providers, using contract data from the Dutch social benefit administration. Our analysis takes full account of selection effects, both ex ante (before the contracting process) as...
