We explore how inherent preferences for reciprocity and repeated interaction interact in an optimal incentive system. Developing a theoretical model of a long-term employment relationship, we first show that reciprocal preferences are more important when an employee is close to retirement. At...

We study a two-period dynamic principal agent model in which two agents with different unobservable abilities compete in a contest for a single prize. A risk-neutral principal can affect the outcome of the contest by dividing a given budget between agents in each period and her net payoff...

We consider the problem of a principal who wishes to contract with a privately informed agent and is not able to commit to not renegotiating any mechanism. That is, we allow the principal, after observing the outcome of a mechanism to renegotiate the resulting contract without cost by proposing...

I use game-theoretical models to compare a sender's expected payoff under two methods of wielding influence under incomplete information: offering rewards or threatening punishments. Attempts to influence another's behaviour can have the perverse effect of actually encouraging the behaviour that...

Increasing concerns about climate change have given rise to the formation of International Environmental Agreements (IEAs) as a possible solution to limit global pollution effects. In this paper, we study the stability of IEAs in a repeated game framework where we restrict to strategies which...

We study the economic consequences of opportunities for dishonesty in an environment where efficiency relevant behaviour is not contractible, but rather incentivized by informal agreements in an ongoing relationship. We document the repeated interaction between a principal and an agent who,...

This paper analyzes a dynamic relational contract for employees with reciprocal preferences. I develop a tractable model to investigate how “direct” performance-pay (promising a bonus in exchange for effort) and generous upfront wages (which activate the norm of reciprocity) interact over...

Governments must usually take policy decisions with an imperfect knowledge of the economic actors' type or the actors' effort level. These issues are addressed within the framework of classic adverse selection or moral hazard models. I discuss in this paper how would the government’s and the...
