In this paper, I construct a general equilibrium model in which the labour market exhibits search frictions, whereas Cournot competition is assumed in the goods market. The properties of the long run free-entry equiibrium show that a more competitive product market raises employment, but it has...

This search-matching model is well suited for an equilibrium evaluation of labor market policies. When those policies are targeted on some groups, the usual juxtaposition of labor markets is however a shortcoming. There is a need for a setting where workers’ productivity depends on employment...

This paper describes an equilibrium matching model with two types of workers producing two different intermediate goods. Labour markets are perfectly segmented, but productive complementarities between sectors and productive substitutability within sectors arise. This deeply changes the effects...

This paper studies an R&D outsourcing contract between a firm and a contractor, considereing the possibility that in the interim stage, the contractor might sell the innovation to the rival firm. Our result points out that due to the competition in the interim stage, the reward needed to prevent...

The purpose of this paper is to test econometrically the existence of fiscal interactions between Belgian municipalities. At the time of writing, the motivation was to provide scientific support to the lively debate on fiscal competition that took place among Belgian politicians in the late...

This paper studies the impact of low-skilled immigration on the host country’s education system, which is characterized by sources of school funding, expenditres per pupil, and types of parents who are more likely to send children to publicly (privately) funded schools. When the size of...

Relying on an original data set on international migration by educational attainment for 1990 and 2000, we analyze the determinants of the brain drain from developing countries. We start from a simple decomposition of the brain drain in two multiplicative components, the degree of openess of...

We design and implement optimal foreign exchange portfolio allocations. An optimal allocation maximizes the expected return subject to a Value-at-Risk (VaR) constraint. Based on intradaily data, the optimization procedure is carried out at regular time intervals. For the estimation of the...

This paper analyses the Belgian monetary and exchange rate policies at the time of Bretton Woods. It sheds light on the groping adjustment process by which internal economic policies are hit by or adapt to the external constraints. In 1944, an ambitious monetary reform laid down the economic...

We estimate by Bayesian inference the mixed conditional heteroskedasticity model of (Haas, Mittnik and Paolelella 2004a). We construct a Gibbs sampler algorithm to compute posterior and predictive densities. The number of mixture components is selected by the marginal likelihood criterion. We...
