Proprietary vs. Public Domain Licensing of Software and Research Products

Hall, Bronwyn H; Gambardella, Alfonso - National Bureau of Economic Research (NBER) - 2005

We study the production of knowledge when many researchers or inventors are involved, in a setting where tensions can arise between individual public and private contributions. We first show that without some kind of coordination, production of the public knowledge good (science or research...
