We consider partnerships among risk-averse professionals endowed with (i) a risky and personally-costly production technology and (ii) a personally-costly monitoring technology providing contractible noisy signals about partners’ productive efforts. Partners shirk both production and monitoring tasks because efforts are unobservable. We characterize optimal partnership size, profit shares and i...

This paper analyses optimal contracts in a principal-agent model where the agent is intrinsically motivated at the outset and there is an endogenous relationship between the structure of incentive payments and intrinsic motivation (crowding effects). The analysis shows that crowding effects have implications for the optimal contract and that under some conditions the principal can do better wit...

We analyze a tractable class of multitask principal–agent problems, such as the one faced by a firm with a manager overseeing several projects. We allow for tasks to be complements or substitutes. We avoid the problems associated with the first-order approach by directly characterizing the shape of the agent’s indirect utility function, which exhibits a convex then concave shape in effort. We i...

This article develops a real options model to study the interaction of industry structure and takeovers. In an asymmetric industry equilibrium, firms have an endogenous incentive to merge when restructuring decisions are motivated by operating and strategic benefits. The model predicts that (i) merger activities are more likely in more concentrated industries or in industries that are more expo...

Economists have by large ignored the phenomena of office politics, such as collusion and favoritism, which prevail in organizations where, due to the subjectivity of performance assessments, the incentive mechanism often takes a form of tournament. This paper studies these phenomena in a stylized tournament model. It finds that favoritism cannot benefit organizations when employees are unable t...

This paper investigates the optimality of sharp incentives in contracts where output prices are set at the time of contracting but are random in nature. It shows that when prices are specified with error, schemes involving sharp incentives might result in substantial deviations from first-best output levels. The randomness of prices creates arbitrage opportunities that are exploited by agents p...

I study asset prices in a two-agent production economy in which the worker has private information about her labor productivity. The shareholder offers an incentive compatible long-term labor contract, which partially insures the worker against labor income risk. I compare the model’s performance to settings with a competitive labor market, and with static labor contracts. My model successfully...

We study learning in communication games. Our main finding is that a simple forward-looking learning rule leads to communication in a large class of games. This class is characterized by a partial-common-interest condition. In contrast, we show that a variety of purely backward looking dynamics may fail to guarantee communication. Memory is a partial substitute for looking forward: With long me...

We characterize the incentive compatible allocation that maximizes the expected social surplus in a single-unit sale when the efficient allocation is not implementable. We then show that allowing for the possibility that the good remains unsold may increase the expected social surplus even when allocating the good to no bidder generates less social surplus than allocating to any of the bidders....

This paper analyses the incentive properties of prospective payment systems for hospital contracts, a key feature in many health systems’ reforms. Building on current literature, the model explicitly allows for the existence of waiting time, modelled as adversely affecting patients’ utility and therefore reducing social welfare. The model shows that rewarding hospitals for their demand leads to...
