This article applies the emerging theory of endogenous market structures to macroeconomic issues through a few simple models. First, we study a model of Schumpeterian growth where strategic interactions and endogenous entry determine the equilibrium behaviour of the firms investing in R&D....

This paper deals with a real-life problem that comes up in the daily management of Service Centres. It is a complex resource allocation and task scheduling problem that has to be solved online in a dynamic and uncertain environment. The uncertainty resides both in the task durations and the task...

In this paper it is shown that quality of care in a hospital setting is not solely determined by the medical treatment of patients. Organizational structure clearly contributes to the qualitative performance measures too. In particular, clinical pathways could be specified in which both...

We depart from the conventional ‘resource constrained project scheduling problem’, better known under the acronym RCPSP, by adding the element of randomness to the activities. In particular, we assume that each activity in the project has a work content that is exponentially distributed. The...

Shortly before the national elections in the Netherlands, the Netherlands Bureau for Economic Policy Analysis (CPB) evaluates the economic effects of the policy proposals in election programs. This paper investigates the sensitivity of this analysis to the uncertainty of parameter estimates in...

We develop a positive non-parametric model of public sector production that allows us to test whether an implicit procedure of cost minimization at shadow prices can rationalize the outcomes of public sector activities. The basic model focuses on multiple C-outputs and does not imply any...

Assessing the price evolution of houses on the basis of average sales prices, as is current practice in Belgium, might be misleading due to changing characteristics of the houses sold in the periods observed. A hedonic index which takes into account changes in characteristics is more...

This paper reviews the empirical literature on the degree of financial integration in EMU and analyzes whether the process of integration accelerated with the introduction of the Euro. If the launch of EMU expedited financial integration, this affected pricing of assets and optimal portfolio...

In this study, we investigate (1) differences in the psychological contract of temporaries and permanents, and (2) the extent to which possible differences are explained by the preferences and prospects of temporaries. Three psychological contract types are distinguished. The relational...
