The GEM Project, by intuitively generalizing rational exchange, has considerably strengthened our capacity to model macro instability. This post begins a series of essays on the policy implications of that breakthrough, with special attention to how best to deal with …

The most embarrassing puzzle in modern macroeconomics is no secret. Total hours worked vary a lot over the business cycle while wages move hardly at all. Everybody knows that reconciling those two facts overburdens the consensus market-centric DSGE model class. …
