Yesterday, I discussed the results of recent research that demonstrated the ‘trickle down’ hypothesis, which has been used to justify the sequence of tax cuts for high income recipients, was without any empirical foundation. While mainstream economists have been enchanted with that hypothesis, heterodox (including Modern Monetary Theory (MMT) economists have never considered it had any validity – neither theoretical nor empirical. But it is good that mainstream researchers are now ratifying that long-held view. Today, I am discussing another case of the mainstream catching up. When I say catching up, the implications of these new empirical studies are devastating for key propositions that the mainstream macroeconomists maintain. The ECB Working Paper series published an interesting paper (No. 2509) yesterday (December 21, 2020) by an Italian economist from the Bank of Italy – Losers amongst the losers: the welfare effects of the Great Recession across cohorts. In brief, the research found that younger people bear disproportionate burdens during recession in the short-run, but also, face diminished prospects over the longer-term. The paper bears on some of the major fictions that have been propagated to disabuse governments of using fiscal deficits to smooth out the economic cycle – namely, the alleged burden that is created by the current generation’s excesses (the deficit) for their children and grandchildren (who according to the narrative have to pay back the debt incurred by the excesses). This is another case of evidence being produced that ratify the analysis that MMT economists have been advancing for the last 25 years.
