This paper investigates necessary conditions for an equilibrium to exist on a reinsurance market with short sale constraints. It establishes that, equilibrium, there exists an equivalent probability measure under which the reinsurance premium is the compensator of the jump process describing the...

The purpose of this paper is to study how the equilibrium, in a linear exchange equilibrium varies, with respect to the initial endowments and the utility vectors.

In this paper the existence of unemployment is partly explaines as being the result of coordination failures. This is achieved by considering a standard general equilibrium modes and splitting the set of commodities in two groups. The first group contains commodities like gold. The prices of...

Individuals exchange contracts for the delivery of commodities in competitive markets and, simultaneously, act strategically; actions affect utilities across individuals directly or through the payoffs of contracts. This encompasses economies with asymmetric information, Nash-Walras equilibria...

This paper analyses the consequences of trust for the general equilibrium in an exchange economy. Trust is viewed as a gift of information which modifies the caracteristics of goods a la Stigler-Becker. The increase in utility due to the increase in information is modified by its consequences on...

This Paper analyses the exchange rate in a ‘no-arbitrage’ or ‘real business cycle’ equilibrium model and provides empirical evidence for this model vis-a-vis PPP. Our contribution is to show, based on a generalization of the equilibrium model of exchange rates, that (i) the test equation...

We present evidence that the predictive ability of the yield spread for short-run inflation is related to its predictive ability for economic activity. In particular, an increase in the slope of the term structure predicts an increase in output growth and a decrease in inflation of equal...

We study the effect of introducing a new security, such as a non-redundant derivative, on the volatility of stock-market returns. Our analysis uses a standard, continuous time, dynamic, general-equilibrium, full-information, frictionless, Lucas endowment economy where there are two classes of...
