This study demonstrates that a model with efficiency wages and imperfect information produces a Phillips curve relationship. Equations are derived for labor demand and the efficiency wage-setting condition, and shifts in these curves in response to aggregate demand shocks result in a relationship with the characteristics of a Phillips curve. The Phillips curve differs from the efficiency wage-setting condition in that the Phillips curve is a more parsimonious expression and has a coefficient on expected inflation equal to 1. Also derived from this model is the counterpart curve to the Phillips curve in unemployment – inflation space.
