Abstract :
A segmented markets model of monetary policy is constructed, in which a novel feature
is goods market segmentation, and its relationship to conventional asset market
segmentation. The implications of the model for the response of prices, interest rates,
consumption, labor supply, and output to monetary policy are determined. As well,
optimal monetary policy is studied, as are the costs of inflation. The model features
persistent nonneutralities of money, relative price effects of increases in the money
supply, persistent liquidity effects, and a negative Fisher effect from a money supply
increase. A Friedman rule is in general suboptimal
