The Great Moderation:Good Luck,Good Policy,or Less Oil Dependence?\n\nAndrea Pescatori  \nThree explanations have been suggested for the moderation in real GDP and inflation that has occurred in industrializedcountries since the 1980s:good luck,better monetary policy,and structural changes in the econony.Recent researchfinds that better monetary policy explains most of the moderation in inflation,and good luck and the lessintensive useof oil(a stuctural change)have played a major role in the moderation of GDP.  \nSometime in the early 1980s,real GDP and inflation inindustrialized countrics began to fuctuate less widcly thanin the past.Economists have been debating the causes ofthis dramatic change.commonly referred to as the “GreatModeration,\"ever since (see figures l and 2).Broadly spcak-ing,thrce explanations have bccn suggestcd:good luck,bctter monctary policy,and structural changcs in theeconomy.Economists of all stripes are interested in which isresponsible,but monetary policymakers,in particular,needto understand the relative importance of cach,as they maybe in a position to kcep up the good work.  \nGood luck refers to the possibility that the remarkablybenign series of economic shocks that have hit the economyin rcccnt years has been thc result of nothing other thanchance.Some cconomists conjccture that stable oil priceshave helped to produce these calm waters,bccause so muchof industrialized countries'output requires oil as an inputto production,and most of these countries import their oil.While today's rising oil prices may sccm to spell he end ofthcse good times,the percentage change in rcent oil priccshas been much less abrupt than in the 1970s(see fgure 3).  \nIf good luck explains the moderation in GDP and infation,though.there's no reason to expcct the moderation to last.But many economists argue that better macrocconomic poli-cics arc responsiblc,particularly monetary policy.If bcttermonetary policy has helped to moderate swings in GDPand inflation,it is important to make sure that this goodpolicy continues.  \nInflation targeting is sccn by some as the bcst way to dothis.A credible target on low inflation helps central banksto stabilize not only inflation but also infation expectations,which by theselves can be a source of acroeconomicinstability,as they can affect interest rates and the realcconomy.Over the past few decades,most of the world'smajor central banks have sought to keep infation low,somegoing so far as to adopt explicit inflation targeting regimes,and proponents of inflation targcting sce the Great Modera-tion as evidcnce of these policies'cffectiveness.  \nOther cconomists arguc that the overall cconomy has under-gone some sort of structural change and is now intrinsicallymore resilient to economic shocks.Alook at the effect of oilprices on the economy provides an example of this resil-ience.Since 1983,incrcases in oil prices have had a muchsmaller cffect on GDP-in the United States as well as mostindustrialized countries.Oil conservation efforts after theoil-price shocks of the 1970s are likely responsible for thisreduced impact,for we now use oilmore efficiently.Theratio of oil to GDP,which shows how much oil is needed toproduce a given dollar of GDP,has fallen about 40 pcrcentsince the 1965-1983 period.  \nMy recent research with Antón Nakov suggests that none ofthese explanations by itsclf accounts for all of the modera-tion in GDP and inflation variability,but cach contributessomething.We have quantificd the impact of these causeson the moderation,and we find that while better monetarypolicy explains most of the moderation in infation,goodluck and the less-intensive use of oil(a structural change)have played a major role in the moderation of GDP.  \nThe Oil Channel  \nIn the past six years,oil prices have increased almost S80 abarrel(from an average of $20 in the first quarter of 2002to $98 in the first quarter of 2008).Unlike the 1970s,thisdramatic price rise has not bcen associated with an incrcase","cbCairz6JaR9NvGY","https://ap.wps.com/l/cbCairz6JaR9NvGY","pdf",1482932,"English","# The Great Moderation\n##
