The business cycle implications of optimal wage indexation are investigated in a dynamic general equilibrium model with wage contracts. As in Gray's seminal contribution on wage indexation, it is shown that the optimal degree of indexation depends on the relative volatilities of monetary and...

We build a dynamic general equilibrium model of a semi-small open economy in which staggered wage contracts are the only source of nominal rigidity. The model is capable of generating highly variable real and nominal exchange rates while predicting relative variabilities of prices and...

We use a dynamic general equilibrium model to obtain quantitative estimates of the welfare costs of nominal wage contracts. We find that the welfare costs of such contracts can vary quite a bit depending on the degree of indexation, the size and persistence of money supply uncertainty and the...

Grâce aux récents développements des méthodes d'approximation numérique, des progrès marquants ont été réalisés pour comprendre et vérifier le comportement d'épargne de précaution. Cet article passe en revue les déterminants de l'épargne de précaution, l'effet des politiques...

This paper explores the quantitative link between export-promoting commercial policies and economic growth. We build and calibrate a dynamic general equilibrium model of a small developing economy. The economy's equilibrium is suboptimal due to monopolistic competition in the manufacturing...

This paper deals with volume of trade and distribution of surplus in markets subject to adverse selection. The benchmark case -- a variation of Akerlof's lemons model -- is that of a market where two qualities of a good are offered, in proportions such that, if a single price is required to...

Quel effet a la variation des taux d'intérêt dans une économie ? Comment peut se déterminer la structure des taux d'intérêt ? Le but de ce travail : nous cherchons à établir les différentes formes de relations optimales de la structure des taux d'intérêt. Nous utilisons une...

We extend the Hansen and Prescott (1991) method for the numerical computation of equilibria of dynamic business cycle models in which there are two sets of agents who play a dynamic Stackelberg game. Such models have application to analysis of issues of optimal government policy in which the...

Ce texte fait le point sur l'état des connaissances théoriques et empiriques quant aux différentiels de taux d/intérêt (et autres déviations par rapport aux conditions internationales de non-arbitrage). Il met particulièrement l'accent sur ce que ces différentiels peuvent nous apprendre...

We build a simple dynamic model of the business cycle with monopolistically competitive firms. With simple assumptions concerning firm entry and exit, the model can explain some important stylised facts of the business cycle which standard real business cycle models with perfect competition...
