This paper extends the classic two-armed bandit problem to a many-agent setting in which N players each face the same experimentation problem. The difference with the single-agent problem is that agents can now learn from the experiments of others. Thus, experiementation produces a public good...

This paper suggests a reason, other than asymmetric formation, why agency contracts are not explicitly contingent on the contracting parties' performances or actions. This reason is the formal nature of contracts: the form, usually written, that contracts are required to take to be enforceable...

Large public bureaucracies are usually less efficient than modern private corporations. This paper explains how the degree of discretionary power might account for this difference in efficiency. In fact, increasing the discretionary power of the intermediate layers of an organization can enhance...

It has been argued that collusion among the members of an organization or a vertical structure creates efficiency losses, and hence should be prevented. This paper shows that whenever collusion takes the form of co-insurance agreements, here called ?friendships?, among the members of a vertical...

We study wage determination in a job-matching model, under the assumption that wages may be continuously renegotiated, so as to reflect the employee's endogenous outside option. We characterize the unique equilibirum of the model and we analyse the distribution of producer surplus. The model is...

We identify and investigate the basic ?hold-up? problem which arises whenever each party to a contingent contract has to pay some ex-ante cost for the contract to become feasible. We then proceed to show that, under plausible circumstances, a ?contractual solution? to this hold-up problem is not...

In an environment in which heterogenous buyers and sellers undertake ex-ante investments, the presence of market competition for matches provides incentives for investment but may leave inefficiencies that take the form of hold-up and coordination problems. This paper shows, using an explicitly...

In a Case Law regime Courts have more flexibility than in a Statute Law regime. Since Statutes are inevitably incomplete, this confers an advantage to the Statute Law regime over the Case Law one. However, all Courts rule ex-post, after most economic decisions are already taken. Therefore, the...

This paper explores the link between boundedly rational behaviour and incomplete contracts. The bounded rationality of the agents in our world is embodied in a constraint that the contracts they write must be algorithmic in nature. We start with a definition of contract incompleteness that seems...
