It can be argued that the contraction in output was larger than it otherwise might have been since monetary policy during the second oil shock had to be tightened sufficiently not only to deal with the second oil shock, but also to counter the inflationary pressures that remained from the first shock.
Additionally, the fact that the monetary authorities did not aim to contain inflation during the first oil price shock implied that it was more difficult during the second shock to alter expectations. Central banks thus faced a high cost, in terms of recessions, in their attempt to restore price stability in the 1980s.
