In this paper the existence of unemployment is partly explained as being the result of coordination failures. It is shown that as a result of self-fulfilling pessimistic expectations, even at Walrasian prices, a continuum of equilibria results, among which an equilibrium with approximately no...

When aggregating individual preferences through the majority rule in an n-dimensional spatial voting model, the "worst-case" scenario is a social choice configuration where no political equilibrium exists unless a super majority rate as high as 1-1/n is adopted. In this paper the authors assume...

In absence of markets for externalities, the authors look for governances and conditions under which majority voting among shareholders is likely to give rise to efficient internalization. The central and natural role played by a governance of stakeholders is underlined and benchmarked.

In this note we study a take-it-or-leave-it bargaining procedure between two risk neutral individuals engaged in the joint stochastic production of a commodity. Each individual has to exert effort, that is, to provide a one-dimensional input which is unobserved to the other individual. The...

In a matching model of firm formation with moral hazard, we characterize the equilibrium for economies with scarcity of capital and study the effects of redistributive taxation. We give necessary and sufficient conditions determining the equilibrium matching patterns, payoffs and interest rate....

When the asset market is incomplete, there typically exist taxes on trades in assets and a redistribution of revenue in the asset market that are Pareto improving. <p> The policy is anonymous, it economizes on complexity, and it results in ex post Pareto optimal allocations, it is publicly...</p>

We consider a model of endogenous occupational choice in economies with a continuum of individuals who differ in their endowments. Individuals have a choice of remaining self-employed or engaging in productive matches with another individual, i.e., forming firms. Matches are subject to a moral...

In exchange economies where moral hazard affects the distribution of individual risks, we study the viability of linear nonexclusive contracts. It is shown that the linearity in prices and payoffs is compatible with the presence of moral hazard when coupled with a simple participation fee. More...

We study an economy with competitive commodity markets and exclusive pairwise contractual relations with moral hazard, where both the principal and the agent can be risk averse. We show existence of equilibria and their generic constrained suboptimality, by means of a change in the compensation...

We prove existence of equilibria with proportional transaction costs on asset trading, using homotopy methods.
