This paper studies the efficiency of competitive equilibria in environments with a moral hazard problem and unobserved states, both with retrading in ex post spot markets. The interaction between private information problems and the possibility of retrade creates an externality, unless...

Credit derivatives allow for buying protection on corporate debt, but also on sovereign debt. In this paper we examine the implications for sovereign debt crises. We show that the availability of credit protection lowers ex-ante debtor moral hazard by allowing a bondholder to improve his...

The financial stability can not be achieved without the existence of a lender of last resort. The Bagehot rule is not always appropriate because the complexity of the financial systems increased and because the financial turbulences have nowadays a global impact. In this study we present the...

The paper discusses moral hazard problems as a potential reason for the observed strong increase of indebtedness of German states (Länder). Indeed, financial markets do not react much to the strong differences in fiscal fundamentals of German Länder. Using a case study, the paper also shows...

We develop and test experimentally a theoretical model of the role of self-esteem, generated by private feedback regarding relative performance, on the behavior of agents working on an effort provision task for a flat wage. Agents work harder and expect to rank better when they are told they may...

This paper studies repeated games where the time of repetitions of the stage game is not known or controlled by the players. Many economic situations of interest where players repeatedly interact share this feature, players do not know exactly when is the next time they will be called to play...

This paper reports 5 laboratory sessions that analyze the effects of group sizes in the voluntary contribution mechanism, when contribution level is either complementary or substitute. The theorical argument is that each production function provides different incentives for the agent along scale...
