This paper studies the production strategies of firms in a duopoly market of homogenous products characterized by quantity competition. Demand is partially unknown and firms are free to produce once, whenever they want before the existence of demand. We show that the nature of the equilibrium in...

Our paper studies two attempts at integrating unemployment in macroeconomics. The first, due to Diamond, consists in a search model exhibiting multiple equilibria. The second is due to Andolfatto and Merz who, more or less simultaneously, were able to integrate the matching function in RBC...

We study information revelation in markets with pairwise meetings. We focus on the one sided case and perform a dynamic analysis of a constant entry flow model. The same question has been studied in an identical framework in Serrano and Yosha (1993) but they limit their analysis to the...

We study how asymmetric information impinge on oligopolistic firms’ decision between direct investment and exports in a game-theoretic model with Bayesian learning. Host firms have superior information about market demand and foreign firms can improve their knowledge if foreign direct...

We study the efficiency of the equilibrium price in a centralized, order-driven market where many asymmetrically informed traders are active for many periods. We show that asymmetries of information can lead to sub-optimal information revelation with respect to the symmetric case. In particular,...

Fudenberg et Kreps (1993), Young (1993), et Sela et Herreiner (1999) ont souligné l'insuffisance du critère de convergence en croyances du processus de Fictitious Play dans un cadre d'apprentissage des équilibres de Nash. En conséquence, nous choisissons d'étudier la convergence en...

Dans cet article, nous formalisons deux critères de décisions qui tentent de rendre compte de deux logiques différentes d'interprétation du Principe de précaution. Le premier critère correspond à la maximisation du minimum de l'espérance d'utilité alors que le second critère correspond...

The aim of this paper is to evaluate to what extent more transparency can reduce the occurrence of speculative attacks. It proposes a survey of the literature about the pros and cons of transparency on the exchange rate market, which is one of the main pillars of the new international financial...

The aim of this paper is to examine common trends and common cycles in Belgian Sectoral output series. A multivariate technique proposed by Engle and Issler [1995] allows to deal with series which simultaneously contain common trends and common cycles. An application of their methodology for...

In December 2005, the Belgian government adopted the law on the Intergenerational Solidarity Pact (ISP) with the objective to increase the employment rate of the elderly. In order to meet that objective, several active ageing policies and reforms were taken. The aim of this paper is to...
