In this paper, we analyze the asymmetric pure strategy equilibria in a dynamic game of pure information externality. Each player receives a private signal and chooses whether and when to invest. In some of the periods, only a subgroup of the players make decisions, which we call bunching, while...

Societies provide institutions that are costly to set up, but able to enforce long-run relationships. We study the optimal decision problem of using self-governance for risk sharing or governance through enforcement provided by these institutions. Third-party enforcement is modelled as a costly...

We investigate the role of settlement in a dynamic model of a payment system where the ability of participants to perform certain welfare-improving transactions is subject to random and unobservable shocks. In the absence of settlement, the full information first-best allocation cannot be...

Exchanges and other trading platforms are often vertically integrated to carry out trading and settlement as one operation. We show that these vertical silos can prevent the full realization of efficincy gains from horizontal consolidation of trading and settlement platforms. Independent of the...

Standard models of promotion tournaments assume that firms can commit to arbitrary tournament prizes. In this paper, a firm's ability to adjust tournament prizes is constrained by the outside labor market, through the wages other firms are willing to offer to the promoted and unpromoted workers....

This paper characterizes long-run outcomes for broad classes of symmetric games, when players select actions on the basis of average historical performance. Received wisdom is that when agent's interests are partially opposed, behavior is excessively competitive: ``keeping up with the Jones' ''...

When people share risk in financial markets, intermediaries provide costly enforcement for most trades and, hence, are an integral part of financial markets' organization. We assess the degree of risk sharing that can be achieved through financial markets when enforcement is based on the threat...

What predictions about behavior in extensive form games can we rigorously justify as implied by rationality or mutual or common knowledge of that rationality? This paper models rational belief revision in extensive form games and uses numerical methods to examine the implications for equilibrium...

It is shown that steady state Markov perfect equilibria of discrete time, infinite horizon, quadratic, adjustment cost games differ from equilibria of their infinitely repeated counterpart games with zero adjustment costs even though no adjustment costs are paid in the steady state. In contrast...

This paper develops a dynamic evolutionary model in which agents make choices on the basis of relative performance criteria. We distinguish two classes of learned behavior: imitative dynamics and a new class of dynamics, "introspective dynamics." Under imitative dynamics, agents compare payoffs...
