Oil and macroeconomic (in)stability
MetadataShow full item record
We analyze the role of oil price volatility in reducing U.S. macroeconomic instability. Using a regime-switching structural model we revisit the timing of the Great Moderation and the sources of changes in the volatility of macroeconomic variables. We find that smaller or fewer oil price shocks did not play a major role in explaining the Great Moderation. Instead oil price shocks are recurrent sources of macroeconomic fluctuations. The most important factor reducing macroeconomic variability is a decline in the volatility of other structural shocks (demand and supply). A change to a more responsive monetary policy regime also played a role.
