I am close to finishing it, and I have been impressed. I will do a longer article (more impressions than a formal review) in the coming days.
Later on, I will be using it as the backup reference for a section on fiscal policy in my MMT primer.
Also on the MMT book front, Pavlina Tcherneva has a book on the case for the Job Guarantee out (affiliate link). It has already been released in some European countries, but not available yet here in North America. I will certainly be looking at it when it is available.
