I have been reading about the Great Depression lately and comparing the sort of pressures that governments were placed under during that time to cut deficits which were rising on the back of a collapse in economic activity to what is going on today. There are many interesting parallels and déjà vu experiences. That research took me into some literature on the way the governments bow to industry demands as aggregate demand collapses. In turn, that led me to the way the military-industrial complex operates. Which took me into another literature on the role of the military-industrial complex in creating wars to provide markets for their goods – the merchants of death. And so it goes. That is the nature of research – it just takes one on a journey and usually to destinations previously not imagined. But this journey also clarifies some issues that readers regularly write to me about. The relationship between Modern Monetary Theory (MMT) as a macroeconomic framework and issues that issues that lie below the aggregate level – such as distributional issues. There are links clearly (for example, income distribution affects aggregate demand) but in other ways what is “good” at the macro level may well be downright disastrous at the micro level. But in dealing with the disaster at the micro level, we always have to be mindful of the way dealing with that disaster impacts on the aggregates. This is particularly important in considering issues relating to trade. The military-industrial complex is an excellent case study of these challenges. Here are some early thoughts.
