International Knowledge Diffusion and Home‐bias Effect: Do USPTO and EPO Patent Citations Tell the Same Story?*

This paper estimates the international diffusion of technical knowledge using patent citations. We control for self‐citations and for procedural differences between patent offices using equivalent patents. We find that (1) there are clear biases in patent examination processes that generate citations in the two offices; (2) at the EPO there is a strong localization effect at the country level, and the size is comparable to that found at the USPTO; (3) technological fields have different properties of diffusion in the two patent offices that do not depend on a patent office bias; (4) using EPO data, the US is not the leading country in terms of citations made and received, as occurs at the USPTO.     

Are returns to research quality lower in agricultural economics than in economics?

We compare effects of research quality and quantity on the salary of academics in agricultural economics and economics departments of the same universities. Agricultural economists get a significantly lower payoff to research quality, whether measured by quality‐weighted journal articles (based on nine different weighting schemes) or by citations. Instead, salary depends on the quantity of journal articles, while article counts have no independent effect on economist salaries. These differences in the reward structure for research are not due to either the extension focus of agricultural economists or to disciplinary differences in publishing with students and instead may reflect institutional factors that govern incentives within universities. One‐third of academics in the agricultural economics departments studied here have doctoral training in economics; the very different disciplinary reward structures may cause frustration for these faculty due to the muted returns to research quality that agricultural economics departments seem to offer.     

Using a distance measure to operationalise patent originality

We introduce a distance measure to operationalise Trajtenberg, Henderson, and Jaffe’s [1997. “University Versus Corporate Patents: A Window on the Basicness of Invention.” Economics of Innovation and New Technology 5: 19–50] originality construct (an ex-ante indicator of firms’ technological capabilities). Our measure captures (1) technological diversity, (2) technology distance from patent antecedents, and (3) degree of novelty per each patented innovation. The V-score measure uses the Derwent World Patent Index system to classify technologies hierarchically – making similarities and differences pronounced. Power is gained by using all of the technology-classification codes describing a focal patent’s claims when calculating whether its technology space was incrementally different or radical from those of its antecedent patents (and identifying whether its technology-class code combinations were commonplace at the time when the patent application was made). Our V-score’s prediction of firms’ performance is contrasted with Hall, Jaffe, and Trajtenberg’s [2001. Hall, B. H., A. B. Jaffe, and M. Trajtenberg. 2001. The NBER Patent Citations Data File: Lessons, Insights and Methodological Tools. NBER Working Paper No. 8498] Herfindahl measure of the same originality construct. Results indicate that the distance measure of technological content produces differently signed results when evaluating patents’ performance effects or predicting a firm’s trajectory.     

Scientific method and retailing research: A retrospective

In this paper, we review the 164 articles published in the Journal of Retailing over the 2002-2007 time-span, the period reviewed by Grewal and Levy in their recent article entitled “Retailing Research: Past, Present and Future” [Grewal, Dhruv and Michael Levy (2007), “Passing the Baton, Journal of Retailing 2001 to 2007,” Journal of Retailing, 83 (4) (in this issue)] for their content. Two study characteristics are reviewed for each publication: (1) approach adopted for methodology (classified into eight categories of Student Surveys, Consumer Surveys, Secondary Data, Laboratory Studies, Industry Surveys, Qualitative Methods, modeling, and other) and (2) inferential tools employed by the scholars. The latter are sub-grouped into six categories of regression, ANOVA/MANOVA, structural equation modeling (SEM), analytical modeling, qualitative analysis, and other. Patterns of the usage of these approaches and techniques are tracked over the years and across content areas. We find that researchers in a particular Substantive Content Area tend to focus on particular methodological approaches and inferential tools. We argue that much is to be gained by shaking up these historical patterns.     

PLACING INNOVATION: AN APPROACH TO IDENTIFYING EMERGENT TECHNOLOGICAL ACTIVITY

Identifying the elements of physical and organizational infrastructure most important for technological innovation is challenging for at least two reasons: measuring technological innovation is difficult; and establishing causality is difficult. In this paper, we partially address these paired challenges by (1) describing a new approach for measuring innovation, and (2) employing that approach to compare established technology regions with emerging ones, and to describe how technologies migrate as they develop.     

Lovely but dangerous: The impact of patent citations on patent renewal

What is the impact of patent citations on patent renewal behaviour? Patent citations are commonly used as an indicator of technology spillovers. For cited patents, therefore, patent citations have a potentially ambiguous impact. On the one hand, patent citations may indicate a scientific breakthrough, a high value of the cited patent and therefore a long survival period. On the other hand, patent citations may indicate competing innovations that render the cited patent obsolete. By discriminating patents by technology field, it is demonstrated that patents that receive citations across technology fields survive longer than other patents. Patents that receive citations within the same technology field lapse earlier.     

Cultural Enthusiasm,Resistance and the Societal Embedding of New Technologies: Psychotropic Drugs in the 20th Century

The societal embedding of new (medical) technologies involves not only market success, but also regulation and public acceptance. Cultural enthusiasm about their benefits and social concerns about their risks and dangers are in this respect important. Conceptualizing interactions between product championing, cultural enthusiasm and resistance, the article analyses three patterns of societal embedding: (1) hype-cycle, (2) contested embedding, and (3) controversy and stalemate. A fourth pattern of waves of enthusiasm and concern is proposed for technologies with unexpected side effects. This pattern is explored and elaborated with a longitudinal case study of the introduction of a particular form of medical technology: psychotropic drugs such as Veronal and Valium in the period 1900–2000.     

International Business Research: Coauthorship Patterns and Quality

The authors investigate published international business research in four international business journals over a 10‐year period, 1995–2004: (a) patterns of coauthorship across regions, and (b) the relation between coauthorship patterns and the quality of international business (IB) articles. A cross‐region coauthorship enhances the quality of an article, suggesting that international collaboration creates synergy in IB research. The authors do not see any positive correlation between alphabetical ordering of coauthor names in multiauthored articles and article quality—a result that is contrary to some evidence in other disciplines. Finally, international management articles appear to be more frequently cited than articles in other IB research areas.     

The Impact of Accounting Education Research

Abstract

This paper presents an exploratory study into the nature and patterns of usage of accounting education research. The study adopts the most accessible metric, Google Advanced Scholar citations, to analyse the impact of research published in the six principal English-language accounting education journals. The analysis reveals a global readership for these journals but evidence of relatively low citation levels. However, papers tended to be cited more than expected in cross-disciplinary education journals, discipline-specific education journals, and non-education journals. Guidance is offered to authors seeking to maximise the impact of their research, and issues of concern are identified for editors and publishers. This is the first paper to look beyond content at the usefulness of research in accounting education as indicated by citations. In doing so, it contributes to the current debate on the quality of this research, and of research in accounting and finance in general.
