Abstract
Using data for 102 U.S. universities, we show that royalty-sharing arrangements (cash flow
rights) vary substantially across universities and that they are largely unrelated to most
observed university characteristics including faculty size, quality, research funding, technol-
ogy mix of the faculty, and size of the technology licensing office. However, higher
inventors’ royalty shares are associated with higher licensing income at the university,
controlling for other factors. The results suggest that monetary incentives from inventions
have real effects in the university sector. (JEL: O31, O34, L3, L01)
1. Introduction
By the end of the 1990s, universities accounted for about 50% of all basic
research in the United States (National Science Board 2000). This academic
research has had real effects on the economy by increasing the productivity of
private sector R&D and the growth in total factor productivity (Jaffe 1989;
Adams 1990; Henderson, Jaffe, and Trajtenberg 1998). These benefits work
through direct knowledge spillovers and the licensing of university-owned
inventions to private firms. Technology licensing activity has grown dramati-
cally in the past two decades.

Over the period 1982–2000, the number of U.S.
patent grants to university inventors rose from 500 to almost 3,800. The number

1. Part of this rapid growth in university innovation and licensing activity is due to the passage
of the Bayh-Dole Act of 1980 (Patent and Trademarks Amendments Act, PL 965-17), which gave
universities the right to patent and a mandate to license discoveries made with federally sponsored
research to the private sector. By the year 2000, nearly all American research universities had
established, or expanded, technology licensing offices and introduced explicit intellectual property
policies and royalty-sharing arrangements for academic scientists.
