Governments should do everything possible to avoid recessions – yet they don’t
In May 2020, the IMF published a new Working Paper (No 20/73) – Hysteresis and Business Cycles – which provides some insights into what happens during an economic cycle. The IMF are somewhat late to the party as they usually are. We have known about the concept and relevance of hysteresis since the 1980s. In terms of the academic work, I was one of the earliest contributors to the hysteresis literature in the world. I published several articles on the topic in the 1980s that came out of my PhD research as I was searching for solutions to the dominant view in the profession that the Phillips curve constraint prevented full employment from being sustained (the inflation impacts!). The lesson from this literature in part – especially in current times – is that governments should do everything possible to avoid recessions. The hysteresis notion tells us clearly that the future is path dependent. The longer and deeper the recession, the more damaging the consequences and the longer it takes to recover while enduring these elevated levels of misery. Organisations like the IMF have never embraced that sort of reasoning, until now it seems. They certainly didn’t act in this way during the Greek disaster. But, better late than never.
