Abstract

How should monetary policy respond to supply shocks in terms of inflation and employment stabilization? We introduce labor force entry and exit in an otherwise standard model with staggered price- and wage-setting to include employment in the model. A welfare-maximizing policy features wage growth stabilization with variation in the employment gap and inflation. Under staggered price- and wage-setting, the real wage adjustments to shocks entail a welfare cost, and variation in the employment gap contributes to reducing the welfare cost. Therefore, leaning against the employment gap induces substantial welfare losses for supply shocks compared to the welfare-maximizing policy.
