This paper assesses the implications for optimal discretionary monetary policy if the slope of the Phillips curve changes. The paper first derives a ‘switching’ Phillips curve from the optimal pricing decision of a monopolistic firm that faces a changing cost of price adjustment. Two states...

This paper develops a general equilibrium monetary model with performance incentives to study the inflation-unemployment relationship. A long-run downward-sloping Phillips curve can exist with perfectly anticipated inflation because workers’ incentive to exert effort depend on financial market...
