Supply Shocks, Wage Stickiness, and Accommodation
NBER Working Paper No. 1119
The main issue discussed in the supply shock literature that followed the oil and food price shocks of the seventies was whether to accommodate. The supply shock reduces the equilibrium level of output, and monetary policy can not affect that. But in the seventies supply shocks were also followed by recessions. The question is whether monetary policy can and should be used to prevent such recessions. The paper analyzes the conditions underwhich a suppiy shock will result in recession, and the potential for monetary policy to offset the fall in output. The basic result is that a pure supply shock need not resultin a recession if the money stock is held constant.Aggregate demand effects associated with the supply shock--including the effectsof monetary policy attempts to fight the inflation caused by the supply shock--may cause a recession, as also may real wage resistance by workers. The choice of policy response to the supply shock then turns on the same basic issues as counter-cyclical policy in general, particularly the relative costs of inflation and unemployment.
