Discretionary policymakers cannot manage private-sector expectations and cannot coordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. To utilize the explanatory power of models with multiple...

We develop a model with labor-market matching frictions that is subject to a range of shocks, including shocks to matching efficiency and bargaining power, and use the model to examine how monetary policy should respond to such shocks. We show that optimal monetary policy is highly efficient at...
