We test the empirical content of the assumption of preference dependent beliefs using a behavioral model of strategic decision making in which the rankings of individuals over final outcomes in simple games influence their beliefs over the opponent's behavior. This approach- by analogy with...

Rational parties enter into a contract if the agreement is mutually beneficial. However, after the contract is formed, changes to the costs and/or benefits of performance may render the original contract undesirable. In this paper, we carry out an incentivized experiment to study the effect of...

We study contracting when both principal and agent have to exert noncontractible effort for production to take place. An analyst is uncertain about what actions are available and evaluates a contract by the expected payoffs it guarantees to each party in spite of the surrounding uncertainty....

We use the theory of abstract convexity to study adverse-selection principal-agent problems and two-sided matching problems, departing from much of the literature by not requiring quasilinear utility. We formulate and characterize a basic underlying implementation duality. We show how this...

African populations need better support through social protection mechanisms. Among those who need social security are millions of older people who, having worked all their lives in the formal sector, are in precarious situations with lower benefits. This study aims to appreciate theoretically,...

We consider an in nitely repeated reappointment game in a principal- agent relationship. Typical examples are voter-politician or government- public servant relationships. The agent chooses costly effort and enjoys being in office until he is deselected. The principal observes a noisy signal of...

This paper studies an infinite horizon repeated moral hazard problem where a single principal employs several agents. We assume that the principal cannot observe the agents' effort choices; however, agents can observe each other and can be contractually required to make observation reports to...

I study a dynamic principal agent model in which the effort cost of the agent is unknown to the principal. The principal is ambiguity averse, and designs a contract which is robust to the worst case effort cost process. Ambiguity divides the contract into two regions. After sufficiently high...

This paper introduces and studies the role of managerial attention allocation constraints in incentive contracts. We extend the traditional moral-hazard benchmark model with multi-tasking and linear incentive contracts by letting the principal choose the amount of monitoring allocated across...

Social interaction with colleagues is an important job attribute for many workers. To attract and retain workers, managers therefore need to think about how to create and preserve high-quality co-worker relationships. This paper develops a principal-multi-agent model where agents do not only...
