. The core predicts a unique and extreme outcome: the entire surplus is split evenly among the buyers when m > n and among … the sellers when m < n; the long side gets nothing. We test this core conjecture in the lab with n + m = 3 or 5 randomly … agreements while trading. Despite frequent attempts to collude and occasional large deviations from the core prediction, we find …

One-sided assignment problems combine important features of two well-known matching models. First, as in roommate … problems, any two agents can be matched and second, as in two-sided assignment problems, the payoffs of a matching can be … with a non-empty core), if a subsolution of the core satisfies [indifference with respect to dummy agents, continuity, and …

The core predicts a unique and extreme outcome: the entire surplus is … split evenly among the buyers when m gt; n and among the sellers when m lt; n; the long side gets nothing. We test this core … deviations from the core prediction, we find that successful collusion is infrequent in both new institutions. A disproportionate …

The ex ante incentive compatible core of an exchange economy with private information is the (standard) core of a … incentive compatible core can be empty, even if utility functions are quasi-linear. If, in addition to quasi-linearity, further … assumptions are made (like independent private values), the non-emptiness of the core follows nevertheless from d?Aspremont and …

A large literature uses matching models to analyze markets with two-sided heterogeneity, studying problems such as the … matching of students to schools, residents to hospitals, husbands to wives, and workers to firms. The analysis typically … assumes that the agents have complete information, and examines core outcomes. We formulate a notion of stable outcomes in …

We introduce a matching model in which agents engage in joint ventures via multilateral contracts. This approach allows … us to consider production complementarities previously outside the scope of matching theory. We show analogues of the … equilibria exist, correspond to stable outcomes, and yield core outcomes. Competitive equilibria exist in our setting even when …

We formulate a notion of stable outcomes in matching problems with one-sided asymmetric information. The key conceptual …
