Emi Nakamura on Central Bank Credibility and the Taylor Rule

Odd Lots

The post-Covid inflation will prove to be a treasure trove for academic economists, as they study what drives inflation, and the power that central banks have to contain it once it gets going. At this year's Jackson Hole Economic Symposium, UC Berkeley professor Emi Nakamura presented a new paper — co-authored with her Berkeley colleagues Jón Steinsson and Venance Riblier — titled Beyond the Taylor Rule. The paper sought to look at the wide range of choices that global central banks made in dealing with inflation to see what if anything could be learned about the Taylor Rule, a load-bearing idea in modern economics that describes what optimal monetary policy looks like when successfully balancing the Federal Reserve's objectives. Their paper discovers that in any bout of inflation, a central bank that has a greater history of fighting inflation also has the ability to deviate further from strict Taylor Rule guidelines, without achieving worse inflation outcomes. In an interview recorded in Jackson Hole, we speak with Professor Nakamura about her work and its implications for central bankers going forward.
