Zvi Griliches, a world-renowned pioneer in the field of productivity growth, has compiled in a single volume his pathbreaking research on R&D and productivity. Griliches addresses the relationship between research and development (R&D) and productivity, one of the most complex yet vital issues...

A new data set (the NSF-Census match) containing information on the R&D expenditures, sales, employment, and other detail for approximately 1,000 largest manufacturing firms in the U.S. during 1957-1977 is analyzed using a standard production function framework augmented by the addition of an...

This paper investigates the relationship between earnings, schooling, and ability for young men and women who entered the labor force during the late 60s and 70s. The emphasis is on controlling for both observed and unobserved family characteristics, extending a framework developed earlier by...

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 focuses on developing and adapting statistical models of counts (non-negative integers) in the context of panel data and using them to analyze the relationship between patents and R&D expenditures. The model used is an application and generalization of the Poisson distribution to...
