This article analyzes the incentive to merge in a context of price competition with horizontal product differentiation. In contrast to the results obtained by Kamien and Zang (1990), we show that merged equilibria can appear in this game. Moreover monopolization of the industry occurs with a...

Using a model of bivariate decision under risk of disease, with separates the financial losses from the health losses, we analyse the curative demand for healthcare and the determinants of overconsumption care problem. We also study the demand for self-protection and the demand for...

We consider corruption behavior in a three-players game : Principal, Agent, Corrupter. When the Principal chooses a fair wage, the Agent faces con°icting interests to reciprocate. This delegation effect is expected to lower the level of corruption as compared to what arises in two-players...

We analyze the effect of the degree of judicial enforcement on the probability of credit constraints, the amount of loan and the probability of default. Contrary to the traditional view on judicial efficiency of credit market, our estimation results show that better judicial enforcement...

In this work, we use the VAR and space-state methodology to analyze how the recent developments in 20 European countries have modified the dynamics of structural shocks. Our results confirm a visible progress in (predominated output fluctuations) supply shocks convergence between the CEECs and...

This paper shows that internationalized production, modelled as trade in inter- mediate goods, challenges the standard result according to which exchange rate volatility insulates small open economies from external shocks. Movements of relative prices aect the economy through an additional...

A well known and established model in communication policy in sociology and mar- keting is that of opinion leadership. It is based on the idea of a two-step flow of communication. Opinion leaders are actors in a society who are able to affect the behavior of other members of the society called...

This paper investigates the combined impact of a first-mover advantage and of firmsí limited mobility on the equilibrium outcomes of a continuous-time model adapted from by Boyer, Lasserre, and Moreaux (2007). Two firms face market development uncertainty and may enter by investing in lumpy...

In his 1971's Dynamic Models of Segregation paper, the economist Thomas C. Schelling showed that a small preference for one's neighbors to be of the same color could lead to total segregation, even if total segregation does not correspond to individual preferences and to a residential...

In this paper we study the problem of long-term capacity adequacy in electricity markets. We implement a dynamic model in which operators compete for investment and electricity production under imperfect Cournot competition. The main aim of this work is to compare three investment incentive...
