That's enough to offset the costs of Universal Pre-Kindergarten through higher tax revenues.

You've heard of the many analysts projects, right?

Scholars give the same dataset/question to a bunch of researchers & they still get different answers.

Ed Leamer has passed away.

Ed was one of my favorite colleagues at UCLA: smart, witty, helpful.

My former colleague Pete Schott who was his student, perfectly captured Ed's quirks on his webpage.
