More evidence that the current inflation is ephemeral

When I am asked whether I still consider the recent bout of inflation to be transitory, I say that transitory means as long as the pandemic disrupts the balance between supply and demand. Note: demand. I have been getting lots of E-mails telling me that Modern Monetary Theory (MMT) is a fraud because of the inflation spike and our denial of the demand (spending) involvement. Apparently, the data shows that large fiscal deficits and central bank bond-buying programs are always inflationary. Good try. I last provided data and analysis of this issue in this blog post – Central banks are resisting the inflation panic hype from the financial markets – and we are better off as a result (December 13, 2021) – where I made it clear that the spikes are a unique coincidence between abnormal, pandemic-related demand and supply patterns. That couldn’t be clearer. And when that sort of imbalance occurs, with the addition of cartel-type price gouging (which has nothing to do with fiscal or monetary policy settings) then MMT predicts a nation will encounter inflationary pressures. The idea that the economy is defined by periods below full capacity when there will be no inflation and beyond full capacity when there will be inflation is not part of the MMT body of knowledge. It is more complicated than that dichotomy which we address in our textbook – Macroeconomics. Supporting this view, is a recent ECB research paper, which uses fairly advanced econometric techniques to decompose one measure of inflationary expectations in a component that reflects short-term risk and another that reflects longer term inflationary expectations. They find the former is driving the current inflation trajectory while the latter is largely stable. That means, in English, that the current inflation is likely to be of an ephemeral nature driven by how long the pandemic interrupts supply chains.
