This is Part 2 of an irregular series I am writing on some of the complexities of Modern Monetary Theory (MMT) that are often overlooked by those who rely on reading airport-style books or Op Eds on the topic. In – Exploring the essence of MMT – Part 1 (March 29, 2022) – I dealt with some conceptual issues about values and theory. Today, I am considering the way to think about the – Job Guarantee – within the MMT framework. The Job Guarantee is at the centre of MMT because it contains an insight that is missing from the mainstream economics – the concept of spending on a price rule. This insight leads to the conclusion that the price level is determined by what the monopoly issuer of the fiat currency – the government is prepared to pay for goods and services. This, in turn, means that the Job Guarantee goes well beyond being a job creation program and constitutes within MMT a comprehensive macroeconomic stability framework – where the so-called trade-off between inflation and unemployment (Phillips Curve) is eliminated. However, while in the real world, complexity enters the scene and we need to be aware of the nuances so that we do not fall into the trap of thinking of the Job Guarantee as an inflation killer.
