Group incentive compatibility for matching with contracts
نویسندگان
چکیده
Hatfield and Milgrom (2005) present a unified model of matching with contracts, which includes the standard two-sided matching and some package auction models as special cases. They show that the doctor-optimal stable mechanism is strategy-proof for doctors if hospitals’ preferences satisfy substitutes and the law of aggregate demand. We show that the doctor-optimal stable mechanism is group strategy-proof for doctors under these same conditions. That is, no group of doctors can make each of its members strictly better off by jointly misreporting their preferences. We derive as a corollary of this result that no individually rational matching is preferred by all the doctors to the doctor-optimal stable match.

The blocking lemma and group incentive compatibility for matching with contracts
This paper considers a general class of two-sided many-to-one matching markets, so-called matching markets with contracts. We study the blocking lemma and group incentive compatibility for this class of matching markets. We first show that the blocking lemma for matching with contracts holds if hospitals’ choice functions satisfy substitutes and the law of aggregate demand. The blocking lemma f...
متن کاملSubstitutes and stability for matching with contracts
We consider the matching problem with contracts of Hatfield and Milgrom (2005), and we introduce new concepts of bilateral and unilateral substitutes. We show that bilateral substitutes is a sufficient condition for the existence of a stable allocation in this framework. However, the set of stable allocations does not form a lattice under this condition, and there does not necessarily exist a d...
متن کاملModelling and Experimental Testing of Asymmetric Information Problems in Lease and Hire Contracts (Based on Contract Theory)
This article aims to study lease and hiring contract in the Iranian-Islamic setting and analyze the asymmetric information problem in these contracts. For doing this, we study the characteristics of lease and hiring contracts in Iran (real world experimental characteristics that recognized in other studies), using library method, then we mathematically model different aspects of asymmetric info...
متن کاملIncomplete Information, Incentive Compatibility, and the Core
We consider an exchange economy in which agents possess private information at the time of engaging in state contingent contracts. While communication of private information is permitted, the true information state is not verifiable. The enforcement of contracts is, therefore, limited by incentive compatibility constraints. We formalize a notion of the core for such an economy. Our analysis can...
متن کاملIncentive Compatibility of Large Centralized Matching Markets
We study the manipulability of stable matching mechanisms. To quantify incentives to manipulate stable mechanisms, we consider markets with random cardinal utilities, which induce ordinal preferences over match partners. We show that most agents in large matching markets are close to being indifferent overall stable matchings. In oneto-one matching, the utility gain by manipulating a stable mec...
