A Search Model of Unemployment and Inflation


In this paper, I introduce money in the standard labor-matching model(Mortensen and Pissarides 1999, Pissarides 2000). A double coincidence problemmakes Fiat Money necessary as a medium of exchange. In the long-run, a rise inthe rate of money growth leads to higher inflation and higher unemployment, sothe long-run Phillips curve is not vertical. The optimal monetary growth ratedecreases with the workers' bargaining power, the level of unemploymentbenefits and the payroll tax rate.
