We consider the role of credit ratings when contracts between investors and portfolio managers are incomplete. In our model, a credit rating and a price on a risky bond both provide verifiable signals about a non-contractible state. We allow the investor to both impose ex ante restrictions on...

I study a relational contracting model, in which the agent's discount factor is fixed and known, whereas the discount factor of the principal is her private information. I find that, in the separating contract, information revelation is always immediate, whereas costly signaling continues for an...

Reward systems based on balanced scorecards typically connect pay to an index, i.e. a weighted sum of multiple performance measures. However, there is no formal incentive model that actually describe this kind of index contracts as an optimal solution. In this paper, we show that an index...

This paper considers a long-term relationship between two agents who undertake costly actions or investments which produce a joint benefit. Agents have an opportunity to expropriate some of the joint benefit for their own use. The question asked is how to structure the investments and division...

Can formal contracts help resolving the holdup problem? We address this important question by studying the holdup problem in repeated transactions between a seller and a buyer in which the seller can make relation-specific investments in each period. In contrast to previous findings, we...

This paper analyzes a multitask Principal-Agent model in which the performance measures of some tasks are subjective and relational contract is needed for incentive provision. We find that rewarding the Agent based on a subjective measure that aggregates performance on multiple tasks can help...

We discuss a principal-agent model in which the principal has the opportunity to include a non-compete agreement in the employment contract. We show that not imposing such an agreement can be beneficial for the principal as the possibility to leave the firm generates implicit incentives for the...

We propose a theory of ex post inefficient renegotiation that is based on loss aversion. When two parties write a long-term contract that has to be renegotiated after the realization of the state of the world, they take the initial contract as a reference point to which they compare gains and...

This paper analyzes bilateral contracting in an environment with contractual incompleteness and asymmetric information. One party (the seller) makes an unverifiable quality choice and the other party (the buyer) has private information about its valuation. A simple exit option contract, which...

The corporate finance literature documents that managers tend to overinvest into physical assets. A number of theoretical contributions have aimed to explain this stylized fact, most of them focussing on a fundamental agency problem between shareholders and managers. The present paper shows that...
