Budget deficits do not cause higher interest rates
I have always been antagonistic to the mainstream economic theory. I came into economics from mathematics and the mainstream neoclassical lectures were so mindless (using very simple mathematical models poorly) that I had plenty of time to read other literature which took me far and wide into all sorts of interesting areas (anthropology, sociology, philosophy, history, politics, radical political economy etc). I also realised that the development of very high level skills in empirical research (econometrics and statistics) was essential for a young radical economist. Most radicals fail in this regard and hide their inability to engage in technical debates with the mainstream by claiming that formalism is flawed. It might be but to successfully take on the mainstream you have to be able to cut through all their technical nonsense that they use as authority to support their ridiculous policy conclusions. That is why I studied econometrics and use it in my own work. It was strange being a graduate student. The left called be a technocrat (a put-down in their circles) while the right called me a pop-sociologist (a put down in their circles). I just knew I was on the right track when I had all the defenders of unsupportable positions off-side. But an appreciation of the empirical side of debates is very important if a credible challenge to the dominant paradigm is to be made. That has motivated me in my career.
