In this paper, we examine the sources of the productivity growth in the U.S. computer industry from 1978 to 1999. We estimate a joint production model of output quantity and quality that distinguishes two types of technological changes: process and product innovations. Based on the estimation...

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 demand such as labor and investment...

We estimate and compare the production structures of the US, Japanese, and Korean total manufacturing sectors for the 1974-1990 period. We employ a translog variable cost function that includes such inputs as labor, materials, physical and R&D capital with the physical and R&D capital treated as...
