A 'folk theorem' originating, among others, in the work of Stiglitz maintains that competitive equilibria are always or 'generically' inefficient (unless contracts directly specify consumption levels as in Prescott and Townsend, thus bypassing trading in anonymous markets). This paper critically...

This paper studies equilibria for economies characterized by moral hazard (hidden action), in which the set of contracts marketed in equilibrium is determined by the interaction of financial intermediaries. The crucial aspect of the environment that we study is that intermediaries are restricted...

Optimal voting rules have to be adjusted to the underlying distribution of preferences. However, in practice there usually is no social planner who can perform this task. This paper shows that the introduction of a stage at which agents may themselves choose voting rules according to which they...

Principal-agent models in which the agent has access to private information before a contract is signed are a cornerstone of contract theory. We have conducted an experiment with 720 participants to explore whether the theoretical insights are reflected by the behavior of subjects in the...

We analyze how transparency affects information acquisition in a bargaining context, where proposers may chose to purchase information about the unknown outside option of their bargaining partner. Although information acquisition is excessive in all our scenarios we find that the bargaining...

A central insight of agency theory is that when a principal offers a contract to a privately informed agent, the principal trades off ex post efficiency in the bad state of nature against a larger profit in the good state of nature. We report about an experiment with 508 participants designed to...

We investigate in this paper the theory and econometrics of optimal matchings with competing criteria. The surplus from a marriage match, for instance, may depend both on the incomes and on the educations of the partners, as well as on characteristics that the analyst does not observe. The...

The condition for when a price control increases consumer welfare in perfect competition is tighter than often realised. When demand is linear, a small restriction on price only increases consumer surplus if the elasticity of demand exceeds the elasticity of supply; with log-linear or...

Bank liquidity is a crucial determinant of the severity of banking crises. In this paper, we consider the effect of fire sales and foreign entry on banks' ex ante choice of liquid asset holdings, and the ex post resolution of crises. In a setting with limited pledgeability of risky cash flows...

An indivisible good is to be consumed by one of several agents. The consumption involves identity-dependent externalities to the non-consumers. Resale markets for such goods are analysed in various institutional settings with complete information, assuming the agents cannot commit to future...
