One apparent reason for deferring a decision – abstaining from choosing, leaving the decision open to be taken by someone else, one’s later self, or nature – is for lack of sufficient confidence in the relevant beliefs. This paper develops an axiomatic theory of decision in situations...

This paper proposes a framework to analyze the functioning of the inter-bank liquidity market and the occurrence of liquidity crises. The model relies on three key assumptions: (i) liquidity provisioning is not verifiable -it cannot be contracted upon-, (ii) banks face moral hazard when...

This paper is a theoretical introduction to modern governance of universities in developing countries. Indeed, adopting the approach of the paradigm of the theory of incentives Laffont and Tirole (1993), this paper discusses the effects of the presence of information asymmetry between the State...

In this paper, we consider a two-period model of migration and remittances as implicit contract in a context of asymmetric information. Our model offers new theoretical findings with respect to the previous literature on the main determinants of remittances. According to self-interest thesis,...

A theory of incomplete preferences under uncertainty is proposed, according to which a decision maker's preferences are indeterminate if and only if her confidence in the relevant beliefs does not match up to the stakes involved in the decision. We use the model of confidence in beliefs...

We provide sufficient conditions for existence and uniqueness of a Cournot equilibrium. The contraction mapping approach is used. Equilibrium is characterized in terms of marginal costs. The result is useful for applications to two-stage games, where, in the first stage, firms incur costs to...

We study how managers respond to hurricane events when their firms are located in the neighborhood of the disaster area. We find that the sudden shock to the perceived liquidity risk leads managers to increase corporate cash holdings and to express more concerns about hurricane risk in...
