We propose four different GMM estimators that allow almost consistent estimation of the structural parameters of panel probit models with fixed effects for the case of small T and large N. The moments used are derived for each period from a first order approximation of the mean of the dependent variable conditional on explanatory variables and on the fixed effect. The estimators…

In Switzerland the new law on health insurance, effective since 1996, introduced pro competitive changes in the market of sickness funds. The legislator expected high mobility between sickness funds of both healthy and sick insured as open enrolment was introduced with the new law. That is why the risk adjustment scheme, that was already introduced 1993, was limited until 2005.…

We develop a new approach to endogenizing technological spillovers. We analyze a game in which firms can first invest in cost-reducing R&D, then compete on the human-capital market for their knowledge-bearing employees, and finally enter the product market. If R&D employees change firms, spillovers arise. We show that technological spillovers are most likely when they…

We analyze the determinants of environmental policy when two firms engage in two types of lobbying against a restriction on allowed pollution: General lobbying increases the total amount of allowed pollution, which is beneficial for both firms. Private lobbying increases the individual pollution standard of the lobbying firm, but has a negative or zero effect on the allowed emissions…

We analyse post-war Dutch migration to New Zealand. We document that history, reflect on analytical and econometric modelling and then combine a sample of Dutch migrants in New Zealand with a representative sample of Dutch in The Netherlands to estimate wage equations and the determinants of the migration decision. We use the results for ex post evaluation of the migration decision…
