Is Japan's Innovative Capacity in Decline?

Branstetter, Lee - 2003

This paper investigates changes in the output and productivity of research and development activities in Japanese manufacturing firms over the 1980s and 1990s. Evidence from aggregate patent and R&D statistics and a micro-level analysis of R&D productivity at the firm-level suggest that there...

Of Time and Space : Technological Spillovers among Patents and Unpatented Innovations during Early U.S. Industrialization

Khan, B. Zorina - 2014

The paper explores the role of institutional mechanisms in generating technological knowledge spillovers. The estimation is over panel datasets of patent grants, and unpatented innovations that were submitted for prizes at the annual industrial fairs of the American Institute of New York, during...

Evaluation and Learning in R&D Investment

Frankel, Alex; Krieger, Joshua L.; Li, Danielle; … - National Bureau of Economic Research - 2023

We examine the role of spillover learning in shaping the value of exploratory versus incremental R&D. Using data from drug development, we show that novel drug candidates generate more knowledge spillovers than incremental ones. Despite being less likely to reach regulatory approval, they are...

Estimating the Effects of R&D on Bell System Productivity : A Model of Embodied Technical Change

Gordon, Roger H. - 1985

This paper develops an econometric model of the effects of R&D effort on the magnitude and characteristics of technical change in the Bell system. We estimate simultaneously a vintage capital production function, embodying several distinct types of capital, and various factor demand functions...

R & D Activities and the Technology Game : A Dynamic Model of U.S.-JapanCompetition

Sato, Ryuzo - 1984

This paper presents an international comparison of R&D activities in basic and applied research. The commonly-held view that Japan is not spending much on basic technology development cannot be empirically substantiated from the study of the historical trends. However, the fact that in the...

Market Demand, Technological Opportunity and Research Spillovers on R&D Intensity and Productivity Growth

Jaffe, Adam B. - 1984

This paper uses sales and patent distribution data to establish the market and technological "positions" of firms. A notion of technological proximity of firms is developed in order to quantify potential R&D spillovers. The importance of the position variables and the potential spilover pool in...
