主题:Inflation and Unemployment in the Long Run Revisited


讲座简介We construct a continuous-time, monetary model with frictional goods and labor markets to revisit the long-run relationship between inflation and unemployment. By endogenizing the value of consumers' outside options and market power in accordance with standard consumer search theory, we generate novel predictions for the slope of the long-run Phillips curve, optimal monetary policy, and outcomes at the frictionless limit. The relationship between ináation and unemployment is non-monotone and, at low inflation rates, an increase in ináation reduces unemployment. The Friedman rule is suboptimal when firms'average bargaining power across markets is low. Markups and markdowns vanish as frictions disappear.
