This paper addresses the question of delegation in an organization where there is an initial asymmetry of information between the principal and the agent. We assume that the principal cannot use revelation techniques à la Baron Myerson to elicit agent's superior information and in contrast, we...

The objective of this paper is to model explicitly the possibility to form temporary matching in a model of two-sided search. The agents (workers and employers) differ by their human quality endowment. In a search equilibrium agents form subintervals and are only matched to agents within their...

En Wallonie, la collecte des déchets est fréquemment déléguée par les communes à une intercommunale ou à un collecteur privé. Par ailleurs, de plus en plus de communes utilisent des conteneurs à puce. Cet article compare les performances en termes de coûts de ces différentes alternatives

This article studies the problem of regulating a monopolist with unknown marginal cost. The problem described differs from Baron and Myerson [1982] because we suppose that the regulator faces a cash-in-advance constraint. The introduction of such a constraint may lead to the collapse of the...

This paper investigates the role of output quality control in a multi agent setting with moral hazard. The principal is in charge of a team of agents who produce the output. The marketing of this output can be either a success or entail huge losses. At the time of marketing the product, the...

In this paper we explain the apparent "diversification discount” of conglomerates without assuming inefficient-cross subsidisation through internal capital markets. Instead we assume that internal capital market efficiently redistributes scare resources across a conglomerate’s divisions...

La Commission européenne vient de décider d’ouvrir d’ici 2010 l’ensemble du marché ferroviaire à la concurrence. À l’avenir, la SNCB ne sera plus la seule compagnie à transporter des passagers dans notre pays. Dans ce numéro de Regards économiques, nous analysons au travers de...

In several OECD countries age-targeted wage subsidies have been introduced to increase the employment of older workers, but evidence on their effectiveness is scarce. This paper examines the effects of a permanent wage cost subsidy in Belgium on the employment rate, working time and hourly wage....

We study the impact of graduating in a recession in Flanders (Belgium), i.e. in a rigid labor market. In the presence of a high minimum wage, a typical recession hardly influences the hourly wage of low educated men, but reduces working time and earnings by about 4.5% up to twelve years after...
