We present a model of endogenous firm growth with R&D investment and innovation as the engine of growth. The objective of our analysis is to present a framework that can be used for microeconometric analysis of firm performance in high-tech industries. The model for firm growth is a partial...

This paper is a re-examination of the relationship between research and development (R&D) activity and total factor productivity (TFP) at the industry level during the period extending from the early 1960's to the mid-1970's. The data base consists of NSF data on applied R&D expenditures by...

This paper presents the results of a study of productivity growth and R&D in the 1970s using data on narrowly defined 'business units within a firm. Estimates are developed under different assumptions about technology ,industry effects, and changes in the return to R&D over time. The R&D data...

A number of market failures have been associated with R&D investments and significant amounts of public money have been spent on programs to stimulate innovative activities. In this paper, we review some recent microeconomic studies evaluating effects of government sponsored commercial R&D. We...

Our test of price-taking behavior looks at the choice of capacity rather than the choice of output.

When output is explained by total man-hours and...

This paper reviews the literature on the relationship of economic growth to the education levels of the labor force. The emphasis is on Ben-Porath's contribution to some of the issues in this field: the endogeneity of schooling, the role of the public sector as an `absorber' of educated labor,...

This paper compares and analyzes the growth of productivity in the manufacturing industries and firms in France and the U.S. based on newly assembled comparable data sets in both countries. Three explanations of the recent productivity slowdown are reviewed: shortfall in physical investment,...

This note reviews the history of the 'residual,' from its earliest articulation in Copeland (1937) to its codification in Solow (1957), describing the various earlier contributions by Tinbergen, Stigler, Schmookler, Fabricant, Kendrick, Abramovitz and others.
