The study of organizational choice is crucial to the understanding of firms' efficiency. We consider this issue applied to contracts on health services. In particular, we analyze the circumstances under which it is better for an insurer to contract with both the hospital and the physician...

We correct an omission in the definition of the domain of weakly responsive preferences introduced in Klaus and Klijn (2005) or KK05 for short. The proof of the existence of stable matchings (KK05, Theorem 3.3) and a maximal domain result (KK05, Theorem 3.5) are adjusted accordingly.

In the standard two-sided matching models, agents on one side of the market (the institutions) can each be matched to a set of agents ( the individuals) on the other side of the market, and the individuals only have preferences defined over institutions ti which they can be matched. We...

We correct an omission in the definition of our domain of weakly responsive preferences introduced in Klaus and Klijn (2005) or KK05 for short. The proof of the existence of stable matchings (KK05, Theorem 3.3) and a maximal domain result (KK05, Theorem 3.5) are adjusted accordingly.

This paper has three objectives: first to analyze the interaction between the basic internal contracts that shape the firm (labour and financial contracts). In particular we show how their temporal dimension are related. The linkage between firm's internal contracts and the project choice...

We study experimentally how the ability to communicate affects the frequency and effectiveness of flexible and inflexible contracts in a bilateral trade context where sellers can adjust trade quality after observing a post-contractual cost shock and a discretionary buyer transfer. In the absence...

Calculating explicit closed form solutions of Cournot models where firms have private information about their costs is, in general, very cumbersome. Most authors consider therefore linear demands and constant marginal costs. However, within this framework, the nonnegativity constraint on prices...

Plaintiffs have either stong or weak cases. Both cases should be taken to court, yet weak cases need more work by the attorney than strong cases. Only the attorney knows whether a case needds additional work or not; the plaintiff is forced to rely on the attorney's recommendation. We show that...
