This paper investigates the impact of health risk on insurance contract with hazard moral. We use a bi-dimensional utility function (wealth and health status). We prove that the type of health risk influences the equilibrium of insurance market. A full coverage is possible with moral hazard....

Two agents sequentially contracts with different principals under moral hazard. If agents care for one another, the second principal gains by insuring them over first wages. Even with independent tasks, the first principal must offer riskier payments to induce effort.

This article uses recent survey data from the Kayes area (Western Mali) to estimate the effect of migration and remittances on the technical efficiency of agricultural households. A theoretical model is developed, which shows that the more insurance is provided by the migrants, the less...

We study an economywhere intermediaries compete over contracts in a nonexclusive insurance market affected by moral hazard. In this context, we show that, contrarily to what is commonly believed, market equilibria may fail to be efficient even if the planner is not allowed to enforce...

In this note, we generalize the results obtained by Barday and Lesur (2005) by considering a bivariated non separable utility function. We characterize optimal health insurance contracts. Moreover, we show that under moral hazard a sufficiently high risk aversion implies that the optimal...

Conflicts of interest are the inherent price to pay to benefit from information synergies offered by multiple financial service providers. We focus on conflicts faced by a investment bank's "guru" sell-side analyst, which is torn between the pro-investor research department favoring fair...

We study incentive-compatible labour contracts in the case where individual productivity, preference for leisure and time preference rate are unobservable by the principal in a two-period model. We first reduce this three-dimensional problem to a standard one-dimensional screening problem....

This article deals with optimal insurance contracts in the framework of imprecise probabilities and adverse selection. Agents differ not only in the objective risk they face but also in the perception of risk. In monopoly, a range of configurations that VNM preferences preclude appears: a...

We study incentive-compatible labor contracts in the case where both individual productivity and subjective discount rate are unobservable by the rm. We rst show that unidimensional manifolds of agents group on the same contract. High , low agents may choose the same contract as low , high...

The present paper thoroughly explores second-best efficient allocations in an insurance economy with adverse selection. We start with a natural extension of the classical model, assuming less than perfect risk perception. We characterize the constraints on efficient redistribution, and we...
