Do Energy-Price Shocks Affect Core-Price Measures?

This paper investigates the relationship between energy-price shocks and three core measures of inflation in a vector autoregression model that incorporates measures of monetary policy and inflation expectations. The sample set includes data at monthly frequencies from 1980 through 2000. We find that that positive energy-price shocks have significant, though small, effects on all core price measures after a lag of 12 to 18 months, but that negative shocks have no discernable impact. The results suggest that relative energy-price changes do not distort the inflation signals that standard core-price measures provide.
