. 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 …

This paper studies the core of combined games, obtained by summing two coalitional games. It is shown that the set of … core of the combined game coincides with the sum of the cores of its components. On the other hand, for non-balanced games …, the binary relation associating two component games whose combination has an empty core is not transitive. However, we …

The seminal contribution of Debreu-Scarf (1963) connects the two concepts of core and competitive equilibrium in … exchange economies. In effect, their core-equilibrium equivalence result states that, when the set of economic agents is … replicated, the set of core allocations of the replica economy shrinks to the set of competitive allocations. Florenzano (1989 …

We introduce a new matching model to mimic two-sided exchange programs such as tuition and worker exchange, in which …
