What caused the Great Moderation?

Well not the great policies of credible inflation concious central banks, according to Nate Cline and Nate Perry. The Nates say in a new paper (here) that it was wage compression, associated to lower rates of unionization and higher average unemployment (or lower growth) and lower pass-through effects, which are associated with globalization. The abstract below.

"Several explanations of the “great inflation moderation” (1982–2006) have been put forth, the most popular being that inflation was tamed due to good monetary policy, good luck (exogenous shocks such as oil prices), or structural changes such as inventory management techniques. Drawing from Post-Keynesian and structuralist theories of inflation, this paper uses a vector autoregression with a Post-Keynesian identification strategy to show that the decline in the inflation rate and inflation volatility was due primarily to (1) wage declines and (2) falling import prices caused by international competition and exchange rate effects. The paper uses a graphical analysis, impulse response functions, and variance decompositions to support the argument that the decline in inflation has in fact been a “wage and import price moderation,” brought about by declining union membership and international competition. Exchange rate effects have lowered inflation through cheaper import and oil prices, and have indirectly affected wages through strong dollar policy, which has lowered manufacturing wages due to increased competition. A “Taylor rule” differential variable was also used to test the “good policy” hypothesis. The results show that the Taylor rule differential has a smaller effect on inflation, controlling for other factors."

PS: An alternative title for the post would be "Nates and the Great Moderation." My son actually loved the Nate the Great books.
