Market Demand, Technological Opportunity and Research Spillovers on R&D Intensity and Productivity Growth
Jaffe, Adam B. - 1984
This paper uses sales and patent distribution data to establish the market and technological "positions" of firms. A notion of technological proximity of firms is developed in order to quantify potential R&D spillovers. The importance of the position variables and the potential spilover pool in...

Product Demand, Cost of Production, Spillovers, and the Social Rate of Return to R&D
Bernstein, Jeffrey I. - 1991
The purpose of this paper is to develop and estimate a model of production with endogenous technological change. Technological change arises from R&D capital accumulation decisions. These decisions respond to market and government incentives and generate R&D capital spillovers. A spillover...

A Model of Research, Patenting, and Technological Change
Kortum, Samuel - 1994
I use the aggregate behavior of three indicators of technology (employment of research scientists and engineers, patented inventions, and total factor productivity) to identify a plausible model of endogenous technological change. In the US (as well as in other developed countries) research...
