Research and Productivity

Conference paper


We propose an informational theory of how research raises productivity. We model research as a signal on an unknown parameter of a technology. Such a signal teaches the firm how to operate the technology it uses now, or one that it intends to use in the future. The paper deals with two topics. The first is the construction of the firm’s knowledge stock, and the second is the interpretation of existing estimates of the rate of return to basic and applied research.


Productivity Growth Effective Signal Steady State Equilibrium Private Rate Potential Entrant
