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. The authors 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.
