Ed Glaeser Signs Off From Economix Blog…

… with a very good column, including these useful words:

Positive economics attempts to understand the world as it is; normative economics describes how the world should be. Most economists spend most of their time doing positive economics, but most economics columns advocate particular policies, which is implicitly normative economics.

It’s a good bookend to Greg Mankiw‘s column from a couple days ago.
Glaeser (who’s showed up on this blog before, and surely will again) isn’t leaving Economix just to sit in the sun; he’s one of several noteworthy contributors to the forthcoming Bloomberg View.
