In this paper I calibrate the contribution of R&D investments to productivity growth. The basis for the analysis is the free entry condition. This yields a relationship between the resources devoted to R&D and the growth rate of technology. Since innovators are small, this relationship is not...

In this paper we (1) estimate the effects of international R&D spillovers on total factor productivity growth of the seven largest industrialized countries (G-7); (2) analyze the effect of spillovers on the structure of production , i.e. the effects on factor dema d such as labor and investment...

Whereas difficulties in measuring the output of service sectors have been well documented, input measures are reasonably accurate. Using U.S. input-output data for the period 1958-87 and a number of indices of skill and occupational change derived from the Dictionary of Occupational Titles and...

We model research as a signal on an unknown parameter of a technology.
