This paper applies to adverse selection theory the advances made in the field of ambiguity theory. It shows that i) a relevant second-best contract induces no production distortion considering the efficient agent as in the standard case. But the principal has to pay a higher information rent...

In this paper, I show that Polleit and Mariano (2011) are right in concluding that Credit Default Swaps (CDS) are per se unobjectionable from Rothbard's libertarian perspective on property rights and contract theory, but that they fail to derive this conclusion properly. I therefore outline the...

Based on recent data concerning the French distribution networks in retail and services, this paper highlights several stylized facts relating to the sector-based differences in the organizational choices. Until now this issue has not been studied in the economical literature. This paper...

This article develops a vertical differentiation model to study the competition and environmental effects of multiplicity of eco-labels within a given market. The focus is on the informational content of multiple eco-labels and whether or not they reflect the environmental qualities the labels...

We study how asymmetric information affects the set of rationalizable solutions in a linear setup where the outcome is determined by forecasts about this same outcome. The unique rational expectations equilibrium is also the unique rationalizable solution when the sensitivity of the outcome to...

Our earlier papers had extend to asymmetric information the classical existence theorems of general equilibrium theory, under the standard assumption that agents had perfect foresights, that is, they knew, ex ante, which price would prevail on each spot market. Common observation suggests,...

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 a financial economy with asymmetric information and incomplete markets, we study how agents, having no model of how equilibrium prices are determined, may still refine their information by eliminating sequentially "arbitrage state(s)", namely, the state (s) which would grant the agent an...

The paper analyzes how uncertainty on traders' participation affects a competitive security market in which there are some informed traders. We show that discontinuities, or "crashes", can arise at equilibrium, even when no investor posts a priori an increasing demand. Because of uncertain...

Official Development Aid allows are volatile, non-predictable and not delivered in a transparent way. All these features reinforce asymmetric information between the citizens and the recipient government about the amount of aid flows received by developing countries. This article uses a...
