A ranking of journals for the aspiring health economist

This article identifies and ranks 104 journals that might logically serve as the core for the interdisciplinary field of Health Economics. These journals are identified by analysing approximately 15 000 articles contained in the current CVs of 100 top health economists. Of the nearly 1200 journals spanned by these CVs, 104 journals were outlets for more than five of these top health economists. The 104 journals are ranked using eigenfactor and article influence scores as well as the percentile rank for each journal within its Institute for Scientific Information category. The primary intention is to create a broad-based journal list that exposes possible research outlets for aspiring health economists and to report the relative rankings of such outlets using established metrics.     

建设项目经济评价中影子价格的分析

经济评价是建设项目投资决策的重要依据，而合理的影子价格是决定经济评价结论的关键。阐述了影子价格的涵义，分析了影响影子价格的因素。影子价格属于重要的国家参数，原则上由国家有关权威机构测算颁布，但由于影子价格种类繁多，本身也在不断变化，相当一部分投入物、产出物的影子价格仍需要由项目评价人自己计算，对其而言，简便、准确的计算方法至关重要。提出了几种计算影子价格的方法，并指出了取用影子价格时应注意的问题。     

Small and Medium-Sized Enterprises in Concern

At present, small and medium-sized enterprises are faced with many serious challenges. Since most of the large-sized enterprises in China are state-owned ones, small and medium-sized enterprises in this article are referred mainly to those in the private sector.     

GATT1994文化贸易产品待遇条款评析

GATT1994第4条是WTO规则体系中唯一一条直接涉及文化产品贸易待遇的条款,其对于文化产品特殊性的认定,国内配额措施背离于多边贸易规则之禁止数量限制原则并在特定条件下例外于WTO体制基石之国民待遇的允许,经历了长久的争论与谈判,体现了文化贸易在多边贸易体系中的独特地位。然而GATT1994第4条的内容却遇到了科学技术的巨大挑战,在文化多样性作为全球公认价值的今天,其适用范围的大小也成为文化价值诉求能否顺利实现过程中的重要问题。     

Do deeper regional trade agreements enhance international technology spillovers?

We examine whether regional trade agreements (RTAs) enhance international technology spillovers using a panel of patent citation data for 114 countries/regions for the period 1991–2007. We use patent citations as a proxy for technology spillovers. The focus of this study is on whether the depth of regional integration matters for technology spillovers among member countries/regions of RTAs. The depth of integration is measured by the extent to which an RTA includes legal obligations outside the current mandate of the World Trade Organization. We find that the depth of integration actually influences technology spillovers and that a deeper integration in a broad sense has a greater impact on technology spillovers than do technology‐related provisions.     

Twenty Years of the Journal of African Business: A Bibliometric Analysis

ABSTRACT

This article presents a bibliometric analysis of the Journal of African Business on its twentieth anniversary. The article focuses on the journal’s intellectual development by objectively examining the evolution of its 20 years of publication, including citations, co-citations, and major researched themes with visualization maps. The findings show that JAB is a young journal in the field of African business. It appears as a collection of articles, keywords, and themes that gathers knowledge. Some of these have well-defined relatedness, while others are loosely clustered together and connected by the simple fact of being published in this journal. This looseness should not be interpreted as a sign of softness but rather as an opportunity for creativity and constructive discourse and as a challenge for the next 20 years of JAB. This study is useful for contributors, readers, and editorial board members who form the journal’s community of knowledge creation.     

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.     

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.     

Patent citations as determinants of grant and opposition: case of European wind power industry

The grant of a patent and filing of an opposition are important events in the lifecycle of a patent. This paper tests the influence of backward citations on the likelihood of a patent grant and, if any, an opposition. Since all citations are not alike, detailed analysis is done by assessing type, nature and origin of citations in European search reports and, where needed, international search reports. The nature of citations, blocking or non-blocking, is found to have a significant impact on the likelihood of a patent being granted. The effect of citations originating during different stages of patent pendency is also explored in this study. For practitioners, the study provides a landscape of the European wind industry that is characterised by popularity of the PCT route, dearth of non-patent citations and dominance of bigger actors. For academics, the study offers novel opportunities to utilise citation based indicators.
