Abstract

We introduce the notion of expectational equilibrium in a very general specification of the many-to-one matching with contracts model. The endogenous variables in an expectational equilibrium are expectations about tradable contracts. Expectational equilibrium outcomes are equivalent to stable outcomes. Substitutability of preferences is a sufficient condition for existence. Expectational equilibrium unifies all the other approaches used in the literature so far, in particular Walrasian equilibrium, Drèze equilibrium, and market clearing cutoffs. It also applies to cases where contracts do not involve money as well as cases where there is a smallest monetary unit of account.
