Here is Part 2 of my analysis of the claim that Japan is not a good demonstration of what happens when macroeconomic policies are pushed beyond their usual limits. I have long argued that trying to apply a mainstream macroeconomics (New Keynesian) framework to the Japanese situation yields nonsensical predictions about rising interest rates, accelerating inflation, rising bond yields and government insolvency. Nothing like that scenario has emerged since Japan has introduced economic policies that ran counter to the mainstream consensus since the 1990s. Japan demonstrates key Modern Monetary Theory (MMT) principles and those that seek to deny that are really forced to invent a parallel-universe version of MMT to make their case. That version is meaningless. In Part 2, we extend that analysis to consider trade transactions, the fear of inflation, and the argument that the current generation are selfishly leaving their children higher tax burdens while we party on.

Well, it’s 2022 already and we enter the 18th year of this blog. Regular readers will know that I have studied the Japanese economy in considerable detail over the course of my career and when it experienced one of the largest commercial asset price bubble busts in history in early 1992, the questions I was asking and the data I was looking out were important in framing the way I have done macroeconomics since. I consider Japan to be one of the nations that was early to embrace the madness of neoliberalism – credit binge, wild property speculation then crash – and the first nation to abandon it in favour of more responsible fiscal policy – which given the circumstances required on-going fiscal deficits exceeding 10 per cent of GDP at times. Its policy approach – including the relatively high deficits, the zero interest rate policy of the Bank of Japan, and then the massive bond-buying program by the same, became the target for various New Keynesian macroeconomists (including Krugman) to prophesise doom. Their textbook models predicted the worst – rising interest rates, accelerating inflation, rising bond yields and then government insolvency as bond markets bailed out and the currency plummetted. Nothing like that scenario emerged. Japan was playing out policies that ran counter to the mainstream consensus in the 1990s and beyond and I learned so much from understanding why things happened there as a consequence. This is Part 1 of a two-part discussion about why Japan demonstrates key MMT principles and how those who wish to deny that reality have to invent a parallel-universe version of MMT to make their case.
