''Supply-side effects of monetary policy and the central bank's objective function''
( 2009, Vol. 29 No.2 )
 
 
This paper considers a new Keynesian model with the cost channel and evaluates the supply-side effects of monetary policy on macroeconomic volatility and welfare, taking into account the endogenous nature of the objective function of monetary authorities. When the cost channel matters, supply-side effects of monetary policy depend on the degree of interest rate pass-through and the degree of price rigidity. Numerical results show that the welfare consequences of an increase in the degree of interest rate pass-through are independent of how the central bank specifies its loss function. By contrast, the welfare consequences of an increase in price rigidity depend critically on the nature of the loss function considered. Macroeconomic volatility as a function of the pass-through is almost independent of the central bank's loss function. In contrast, this volatility as a function of the degree of price rigidity depends more on the nature of the loss function.
