A simple search model of money with heterogeneous agents and partial acceptability
Simple search models have equilibria where some agents accept money and others do not. We argue such equilibria should not be taken seriously - which is unfortunate if one wants a model with partial acceptability. We introduce heterogeneous agents and show partial acceptability arises naturally. There can be multiple equilibria with different degrees of acceptability. Given the type of heterogeneity we allow, the model is still simple: equilibria reduce to fixed points in [0,1]. We show that with other forms of heterogeneity, equilibria are generally fixed points in set space, and there ...

The search-theoretic approach to monetary economics: a primer
The authors present simple versions of models used in the search-theoretic approach to monetary economics. They discuss results on the existence of monetary equilibria, the potential for multiple equilibria, and welfare. Using bilateral bargaining theory, they consider models where prices are fixed as well as those where prices are determined endogenously. After describing the frictions necessary to construct a model where money has an essential role, they conclude by reviewing many extensions and applications in the related literature
