This paper analyzes the relationship between output, employment, and physical and R&D capital, for a sample of 133 large U.S. firms covering the years 1966 through 197'.In the cross sectional dimension, there is a strong relationship between firm productivity and the level of its R&D...

We compute rates of growth in labor productivity during the 1973-80 period for samples of individual manufacturing firms, in both Japan and the U.S., and relate them to differences in the rates of growth in their capital-labor ratios and in their intensities of R&D effort. Japanese firms spent...

Some aspects of the econometric estimation of production functions are discussed, focussing primarily on the issue of simultaneity and reviewing the stream of criticisms of Douglas' work and the response to it. We look in particular at the work that uses panel data on micro data for plants or...

We estimate separate productions functions for approximately 450 manufacturing firms each in France and the United States and for 850 manufacturing firms in Japan, covering the 13 year period 1967-1979, and focus on the wide dispersion in the estimated slope coefficients in all three countries....

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 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...

In this paper we focus on alternative procedures for calculating and interpreting quality-adjusted price indexes for microcomputers, based on a variety of estimated hedonic price equations. Our data set comprises an unbalanced panel for 1265 model observations from 1982 to 1988, and includes...

This survey reviews the growing use of patent data in economic analysis. After describing some of the main characteristics of patents and patent data, it focuses on the use of patents as an indicator of technological change. Cross-sectional and time-series studies of the relationship of patents...

We present a model of endogenous firm growth with R&D investment and stochastic innovation as the engines of growth. The model for firm growth is a partial equilibrium model drawing on the quality ladder models in the macro growth literature, but also on the literature on patent races and the...
