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.
