On August 6, 2018, British tax expert Richard Murphy who is becoming increasingly sympathetic to the principles of Modern Monetary Theory (MMT) published a blog post, which recorded an exchange with one James Meadway, who is the economics advisor to the Shadow Chancellor John McDonnell in Britain. The exchange took place on the social media page of a Labour Party insider who has long advocated a Land Tax, which McDonnell is on the public record as saying will “raise the funds we need” to help local government. He called it a “radical solution” (Source). An aside, but not an irrelevant one. It reflects the mindset of the inner economics camp in the British Labour Party, a mindset that is essentially in lockstep with the neoliberal narrative about fiscal policy. Anyway, his chief advisor evidently openly attacked MMT as “just plain old bad economics” and called it a “regression in left economic thinking” which would ultimately render the currency “entirely worthless” if applied. He also mused that any application of MMT would be “catastrophic” for Britain. Apparently, only the US can apply MMT principles. Well, the exchange was illustrative. First, the advisor, and which I guess means the person being advised, do not really understand what MMT is. Second, the Labour Party are claiming to be a “radical and transformative” force in British politics, yet hang on basic neoliberal myths about the monetary system, which is at the core of government policy implementation. Astounding really. This is Part 1 of a two-part series on this topic, most of it will be summarising past analysis. The focus here is on conceptual issues. Part 2 will focus more specifically on Balance of Payments issues.
