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...

This study develops models in which workers form expectations of average wages in choosing levels of effort and on-the-job search. It is assumed that information on lagged average wages is available at a low fixed cost, whilst acquiring other information requires an additional variable cost....
