In a two-stage game with three firms and two countries, we study the profitability of a domestic merger in the context of an international oligopoly game with differentiated products and in a strategic trade policy environment. In contrast to a completely unregulated economy, we show that the...

Nous caractérisons les sentiers d’exploitation optimale de deux énergies primaires parfaitement substituables : une ressource non renouvelable carbonée et une ressource renouvelable non polluante. Ces ressources approvisionnent les besoins en énergie de deux secteurs qui se différencient par leur...

This article addresses the existence of a wide range of estimated government spending multipliers in a dynamic stochastic general equilibrium model of the euro area. Our estimation results and counterfactual exercises provide evidence that omitting the interactions of key ingredients at the...

Je caractérise les défis et écueils auxquels nous devons faire face pour sortir pour de bon des crises financières et récessions économiques récentes et à venir. Je propose une brève histoire de la dernière crise et insiste sur la perte de confiance au sein du secteur bancaire et financier, qui s’...

This paper deals with the study of "\textit{sharp localized}" solutions of a nonlinear type Schr\"odinger equation in the whole space $\R^N,$ $N\ge1,$ with a zero order term, in modulus, like a power $m$ less than one of the modulus of the solution, and with a non zero external forcing term $\f.$...

We prove some existence (and sometimes also uniqueness) of weak solutions to some stationary equations associated to the complex Schrödinger operator under the presence of a singular nonlinear term. Among other new facts, with respect some previous results in the literature for such type of...

We prove the compactness of the support of the solution of some stationary Schr\"odinger equations with a singular nonlinear order term. We present here a sharper version of some energy methods previously used in the literature and, in particular, by the authors.

We consider a model with an infinite numbers of states of nature, von Neumann - Morgenstern utilities and where agents have different prob- ability beliefs. We show that no-arbitrage conditions, defined for finite dimensional asset markets models, are not sufficient to ensure existence of...

Assessing the welfare impact of consumer health advisories is a thorny task. Recently, Shimshack and Ward (2010) studied how U.S. households responded to FDA’s 2001 mercury-in-fish advisory. They found that the average at-risk household reduced fish consumption by about 24%, resulting in a 21%-...
