Our earlier papers had extended to asymmetric information some classical existence theorems of general equilibrium theory, under the standard assumption that agents had perfect foresights, that is, they knew at the outset which price would prevail tomorrow on each spot market. Yet, observation...

In three related papers, we consider a pure exchange financial economy, where agents may observe private information signals, form private anticipations and face an "exogenous uncertainty", on the future state, and an "endogenous uncertainty", on the future prices. At a sequential equilibrium,...

We consider a pure exchange financial economy, where agents observe private information signals, form private anticipations and face an "exogenous uncertainty" on the future state, and an "endogenous uncertainty", on the future prices. At a sequential equilibrium, all agents expect the "true"...

This paper analyses the impact of migrant remittances on the supply of labour of beneficiaries in a developing country. The model is cast as a two period game between a resident and an altruistic migrant, under imperfect information of the latter about the true economic situation of the former....

In this paper we analyze the decision of "working" versus "not working" within a discrete choice framework, where number of available jobs is confined and related to individual characteristics. In this way the market constraint from the demand side is taken into account. We also accommodate the...

We consider an intertemporal economy with liquidity constrained and unconstrained individuals. A liquidity constraint prevents marketability of future income and thus endogenously generates market incompleteness. In contrast with the existing literature on portfolio constraints, our liquidity...

This paper investigates the importance of market incompleteness by comparing the rates of risk aversion estimated from complete and incomplete markets environments. For the incomplete-markets case, we use consumption data for 50 U.S. states. While the use of state-level data is conceptually...

Le dynamisme des petites entreprises n’est pas une fin en soi, mais un élément du secteur des PME qui concourt à la progression globale de la productivité. Il favorise les gains de productivité en redistribuant les ressources vers les entreprises les plus efficientes et en renforçant la...

French Abstract: Les chocs de revenus subis par les ménages les plus démunis peuvent inciter les parents à retirer leurs enfants de l'école pour les introduire sur le marché du travail, lorsque les autres instruments de maîtrise des risques sont insuffisants. Ces réponses aux chocs à...

In this paper, we consider American option contracts when the underlying asset has stochastic dividends and stochastic volatility. We provide a full discussion of the theoretical foundations of American option valuation and exercise boundaries. We show how they depend on the various sources of...
