If we accept the rapidly growing body of evidence and authority suggesting that many of the core concepts of conventional macroeconomics are bollox, and that economists don’t really know what they’re doing, then the important question becomes ‘What next?’ As conventional macroeconomic theory crumbles in the face of facts, what will replace it?
One of the primary contenders is Modern Monetary Theory, which focuses on money itself (something which, believe it or not, conventional macroeconomic theory doesn’t do). Another possibility is that macroeconomics will learn from complexity and systems theory, and that its models (and, hopefully, their predictive ability) will become more like those used in meteorology and climate science. Anti-economist Steve Keen is working in this direction, influenced by the Financial Instability Hypothesis (FIH) of Hyman Minsky, whatever that is.
But wherever macroeconomics is going, it’s clear that the old order is collapsing. The theoretical orthodoxy that has guided the highest level of economic management for many decades is crumbling. Either economics is an objective science or it’s not. And if economics is not an objective science, then we quickly need an economics that is. Countless livelihoods and lives will be deeply affected by the revolution we are witnessing in theoretical macroeconomics. It may be dry, it may be boring, it may be theoretical, and it may seem incomprehensible.
But it’s hard to think of any discussion that’s more important.
