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"...

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...

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....

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...

L'Union européenne (UE) se trouve confrontée à un besoin critique de terres rares, en particulier de produits raffinés essentiels à la production de voitures électriques, de turbines et d'autres applications technologiques. Cependant, le processus de raffinage est non seulement...

Le continent africain devient de plus en plus un champ de bataille dans la course entre les superpuissances pour l'accès aux minéraux essentiels à la « révolution verte », tels que les minéraux des terres rares (REE). Les entreprises chinoises, américaines et russes jouent un rôle...

The African continent is increasingly becoming a battleground in the race between superpowers for access to critical minerals needed for the 'Green Revolution', such as rare earth minerals (REE). Companies from China, the USA and Russia play a major role. In most cases, critical minerals are...
