What matchings can be stable? The testable implications of matching theory


This paper studies the falsifiability of two-sided matching theory when agents' preferences are unknown. A collection of matchings is rationalizable if there are preferences for the agents involved so that the matchings are stable. We show that there are nonrationalizable collections of matchings; hence, the theory is falsifiable. We also characterize the rationalizable collections of matchings, which leads to a test of matching theory in the spirit of revealed-preference tests of individual optimizing behavior.
