Aggregate Demand Management in Search Equilibrium
http://www.jstor.org/pss/1837124
Abstract
Equilibrium is analyzed for a simple barter model with identical risk-neutral agents where trade is coordinated by a stochastic matching process. It is shown that there are multiple steady-state rational expectations equilibria, with all non-corner solution equilibria inefficient. This implies that an economy with this type of trade friction does not have a unique natural rate of unemployment.
