Innovation
Innovation is the creation and commercial implementation of a new product or process, often (but not necessarily) based on new technology. Innovation is a major source of private business success and competitive advantage, and is the major long‐term source in growth in per capita income in an economy. The innovation process is characterized by a high level of uncertainty, long lead times, and “spillovers” of economic benefits whereby innovators c…
Technology Diffusion
Technology diffusion is the process by which new technologies are adopted for use across individual firms or households in a given market, and across different markets. The most salient facts about this process are that it always plays out over time, and the time before adoption is widespread varies greatly across technologies. The dominant explanations for gradual adoption are the time needed for information about the technology to diffuse, and …
Innovation and Its Discontents
In the last two decades, the role of patents in the U.S. innovation system has become increasingly troublesome, driven by two apparently mundane changes in patent law and policy.Economic analysis does not support abolishing patents, and even weakening the fundamental presumption of validity for appropriately issued patents would carry serious policy risks.The alternative is to make sure that, before they can be used to restrict the commercial act…
A tale of two market failures
Patents, Citations, and Innovations
Innovation and technological change, long recognized as the main drivers of long-term economic growth, are elusive notions that are difficult to conceptualize and even harder to measure in a consistent, systematic way. This book demonstrates the usefulness of patents and citations data as a window on the process of technological change and as a powerful tool for research on the economics of innovation. Patent records contain a wealth of informati…
Environmental Policy and Technological Change
The NBER Patent Citation Data File
This paper describes the database on U.S. patents that we have developed over the past decade, with the goal of making it widely accessible for research. We present main trends in U. S. patenting over the last 30 years, including a variety of original measures constructed with citation data, such as backward and forward citation lags, indices of "originality" and "generality", self-citations, etc. Many of these measures exhibit interesting differ…
Knowledge Spillovers and Patent Citations
Knowledge Spillovers and Patent Citations: Evidence from a Survey of Inventors by Adam B. Jaffe, Manuel Trajtenberg and Michael S. Fogarty. Published in volume 90, issue 2, pages 215-218 of American Economic Review, May 2000
The Induced Innovation Hypothesis and Energy-Saving Technological Change
We develop a methodology for testing Hicks's induced innovation hypothesis by estimating a product-characteristics model of energy-using consumer durables, augmenting the hypothesis to allow for the influence of government regulations. For the products we explored, the evidence suggests that (i) the rate of overall innovation was independent of energy prices and regulations; (ii) the direction of innovation was responsive to energy price changes …
Universities as a Source of Commercial Technology
This paper explores the recent explosion in university patenting as a source of insight into the changing relationship between the university and the private sector. Before the mid-1980s, university patents were more highly cited, and were cited by more diverse patents, than a random sample of all patents. More recently several significant shifts in university patenting behavior have led to the disappearance of this difference. Thus our results s…
University Versus Corporate Patents
This paper is an attempt to quantify key aspects of innovations, ‘basicness’ and appropriability, and explore the linkages between them. We rely on detailed patent data. particularly on patent citations, thus awarding the proposed measures a very wide coverage. Relying on the prior that universities perform more basic research than corporations, we find that forward-looking measures of ‘importance’ and ‘generality’ capture aspects of the basicnes…
Environmental Regulation and Innovation
In a 1991 essay in Scientific American, Michael Porter suggested that environmental regulation may have a positive effect on the performance of domestic firms relative to their foreign competitors by stimulating domestic innovation. We examine the stylized facts regarding environmental expenditures and innovation in a panel of manufacturing industries. We find that lagged environmental compliance expenditures have a significant positive effect on…
The energy-efficiency gap What does it mean?
Geographic Localization of Knowledge Spillovers as Evidenced by Patent Citations
We compare the geographic location of patent citations with that of the cited patents, as evidence of the extent to which knowledge spillovers are geographically localized. We find that citations to domestic patents are more likely to be domestic, and more likely to come from the same state and SMSA as the cited patents, compared with a “control frequency” reflecting the pre-existing concentration of related research activity. These effects are p…
Demand and Supply Influences in R & D Intensity and Productivity Growth
The effects of technological opportunity, market demand and RD with respect to productivity growth, it is not possible to distinguish demand and technological opportunity effects, but spillovers are important
