Last week, I wrote this blog post – OECD is apparently now anti austerity – warning, the leopard hasn’t changed its spots (January 12, 2021) – which warned against accepting the idea the growing number of mainstream economists, who were now advocating fiscal dominance, was evidence of a fundamental shift in New Keynesian thinking about macroeconomics. The reality is that they haven’t really shifted much at all and Max Planck’s postulate that paradigms shift one funeral at a time remains true. There are very few cases where the senior members of a dominant paradigm, voluntarily abandon their views when the evidence becomes overwhelmingly against them. They iterate, they declare ad hoc anomalies, they try to voice ideas that a new rival paradigm is articulating which resonate better with the data. This sort of strategy is common across academic disciplines which are under assault from a combination of poor predictive performance (data incongruity) and the arrival of a more convincing alternative paradigm. It is in full swing in macroeconomics now. But don’t believe these characters are suddenly accepting Modern Monetary Theory (MMT) and realising their previous belief system was never a sound way of characterising our fiat monetary systems. If you dig you discover these characters remain charlatans and will do almost anything to maintain their status as the dominant economists.

In the last week, we have heard from the Chief Economist at the OECD (Laurence Boone), who has been touted on social media as offering a fundamental shift in economic thinking at the institution towards fiscal dominance. This is an example of a series of public statements by various New Keynesian (that is, mainstream macroeconomists) who are apparently defining the new macroeconomics of fiscal dominance. The point is this. Within the mainstream macroeconomics there was always scope for discretionary fiscal intervention under certain conditions. The conditionality is what separates their version of the possibilities from those identified and explained by Modern Monetary Theory (MMT). Just because these characters are coming out of their austerity bunkers to scramble to what they think is the right side of history doesn’t mean their underlying economics has changed. If you dig, you will find the same framework in place, just nuanced a little to suit the times. But the leopard hasn’t changed its spots. The underlying train wreck is still there and will be rehearsed again at some future date unless we push forward in abandoning the whole New Keynesian approach.
