We provide necessary and sufficient conditions for observed outcomes in extensive game forms, in which preferences are unobserved, to be rationalized first, partially, as a Nash equilibrium and then, fully, as the unique subgame-perfect equilibrium. Thus, one could use these conditions to find...

Two main results have been obtained on the literature on contractual solutions to the hold-up problem. First, a contract specifying a price and quantity of the final good to be traded will, fairly generally, induce efficient investments if these are `selfish' in nature, i.e., each party's...

When a seller gives a buyer a right of first refusal, although it reduces the competing buyers' profits and creates an inefficiency, it always increases the joint profit of the seller and the right holder. Right of first refusal with a consideration (e.g., a payment from the right holder to the...

The present article provides an economic analysis to examine how contract damages affects both breach and investment decisions over time. Unlike the standard static model, this article studies a model in which, upon signing a contract, a seller invests over two periods, and a buyer may breach at...

We explain why organizations that limit the voice of their agents can benefit from granting them an exit option. We study a hierarchy with a principal, a productive supervisor and an agent. Communication is imperfect in that only the supervisor can communicate with the principal, while the agent...

We study legal restrictions on private contracting in the form of limitations on the severity of non-monetary punishments. We locate the rationale for such restrictions in externalities that parties impose on future relationships: punishments that lower an agent's future productivity may lower...

We give necessary and sufficient conditions for the existence of symmetric equilibrium without ties in common values auctions, with multidimensional independent types and no monotonic assumptions. When the conditions are not satisfied, we are still able to prove the existence of pure strategy...

In this paper we characterize the optimal allocation mechanism for $N$ objects, (permits), to $I$ potential buyers, (firms). Firms' payoffs depend on their costs, the costs of competitors and on the final allocation of the permits, allowing for externalities, substitutabilities and...

The optimal organizational form and optimal incentive contract are characterized for a team of money managers, assuming that the investor (principal) is risk averse and that each manager's (agent's) actions affect both that manager's expected return and the correlation of returns between...

This paper models individual choices of social groups and the formation of group identity, and examines the conditions with which the group identity reinforces the productivity of individuals. A social group is defined as a network that provides with a market for interactions to its members....
