The NBER Working Paper Series at 20,000

1. The Origin and Evolution of the
NBER Working Paper Series
James Poterba, MIT and NBER
July 2014

2. The Beginning
Bob Michael seeks an outlet for research from the NBER
Center for Economic Analysis of Human Behavior and
Social Institutions (December 1972)
The Vision: “What I have in mind is simply a new heavy
paper cover for manuscripts much like that used by many
departments of economics and university research
institutes …”
Key Design Feature: “… [working papers have] not
undergone the full critical review accorded the National
Bureau’s studies…”
