Regular readers will know that for the last few years I have been documenting the way that the dominant paradigm in macroeconomics (New Keynesianism) is slowly disintegrating as the dissonance between its empirical predictions and reality becomes too great to ignore and justify. The once-in-a-century pandemic hasn’t given us much to celebrate in 2020. One cause for optimism, perhaps, is that we might finally jettison the mainstream economics fictions about government deficits and debt, which have hampered prosperity over several decades. Last week (August 27, 2020), the US Federal Reserve Bank Chairman, Jerome Powell made a path breaking speech – New Economic Challenges and the Fed’s Monetary Policy Review – at the annual economic policy symposium sponsored by the Federal Reserve Bank of Kansas City at Jackson Hole. On the same day, the Federal Reserve Bank released a statement – Federal Open Market Committee announces approval of updates to its Statement on Longer-Run Goals and Monetary Policy Strategy. We have now entered a new phase of the paradigm shift in macroeconomics.
