This paper proposes a new approach for modeling investor fear after rare disasters. The key element is to take into account that investors' information about fundamentals driving rare downward jumps in the dividend process is not perfect. Bayesian learning implies that beliefs about the...

An agent can choose to forego benefits from side opportunities and to instead provide benefits to the principal. In return, the principal offers rewards. If this exchange is not contractible, typically repeated interaction will be required to sustain it. This model allows the agent's...

Flexibility - the ability to react swiftly to others' choices - facilitates collusion by reducing gains from defection before opponents react. Under imperfect monitoring, however, flexibility may also hinder collusion by inducing punishment after too few noisy signals. The combination of these...

Understanding the impact of legal protection on investment is of major importance. This paper provides a framework for addressing this issue, and shows that investment may actually be higher in the absence of legal protection. Focusing on the application to innovation, in an environment where an...

Recent evidence highlights the importance of social norms in many economic relations. Many of these relationships are long-term and provide repeated game incentives for performance. We experimentally investigate interaction effects of reciprocity and repeated game incentives in two treatments...

We model cooperation between an employer and a workers' union as an equilibrium in an infinitely repeated game with discounting and imperfect monitoring. The employer has private information about firm profitability. The model explains the incidence and duration of strikes, as well as the...

Leniency programmes (or policies) reduce sanctions against cartel members that self-report to the Antitrust Authority. We focus on their ability to directly deter cartels and analogous criminal organizations by undermining internal trust, increasing individual incentives to ‘cheat’ on...

This paper develops a theory of regular Markov perfect equilibria in dynamic stochastic games. We show that almost all dynamic stochastic games have a finite number of locally isolated Markov perfect equilibria that are all regular. These equilibria are essential and strongly stable. Moreover,...

I treat international merger policy as a repeated veto game. I derive optimal equilibria and consider a series of comparative statistics and extensions.

Collusive agreements and relational contracts are commonly modeled as equilibria of dynamic games with the strategic features of the repeated Prisoner's Dilemma. The pay-offs agents obtain when being ‘cheated upon’ by other agents play no role in these models. We propose a way to take these...
