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.     

Synergies or Trade-Offs in University Life Sciences Research

Major legislative, legal, and technological changes paved the way for a period of remarkable growth in the patenting of life science research by U.S. universities in the 1980s and 1990s. Using a multiple-output cost framework and two decades of panel data on ninety-six universities, this article examines whether economies of scope and/or scale are present in university production of three major life science research outputs: journal articles, patents, and doctorates. The results show strong evidence of economies of scale in life science research production with mixed evidence of economies of scope between articles and patents.     

Agricultural Economics in the JAE: Some Editorial Reflections

On retirement from the post of Editor in Chief of the JAE, it is appropriate that I offer some reflections on my editorship. First, I review the general performance of the journal over the period 2005-2023, and conclude that the JAE has held its own amongst our peers though this is is largely due to our authors and reviewers, rather than the Editor. Second, I consider the subject matter and citation scores of our published papers over this period, as a reflection of the evolution of the state of the art of the Agricultural Economics profession. Here, I illustrate the increasing number and subject/method range of published papers, but raise some questions about what, exactly, citations really indicate. I conclude with some reflections on the challenges and opportunities for the profession.

INFORMATION AND COMMUNICATION: THE SERVICES OF THE COMMONWEALTH BUREAU OF AGRICULTURAL ECONOMICS

The need for an information service in agricultural economics and rural sociology is apparent from the quantity of publications. The Bureau has evolved in response to progressive recognition of this need and from earlier attempts to meet it. An information service must provide for awareness of contents of current publications, and for retrieval of information from accumulated stores. The Bureau's journal, World Agricultural Economics and Rural Sociology Abstracts (WAERSA), is designed to provide these services mainly by citation of classified literature together with abstracts and author, subject and geographical indexes. Classification and subject indexing raise conceptual problems which are being handled by empirical methods. A work flow line is designed to deal smoothy with current world publications. Review articles provide complementary information. Editors and authors can facilitate the work of the Bureau by attention to form and substance of primary publications. The present situation is hardly appropriate for use of computer-based services except possibly for inter-disciplinary linkages. It is hoped that the Bureau will eventually operate in conjunction with a comprehensive international library, around which research, teaching, editorial and information services will interact.     

Criteria for a system level evaluation of farm advisory services

Agricultural advisory services are meant to provide farmers with relevant knowledge and networks for innovation, as well as adjustments to policy and markets in agriculture. Despite substantial investment into these services, there has been little evaluation of their performance and impact, in particular at a system level. A system level analysis is especially challenging in countries with a diverse and fragmented advisory community such as the United Kingdom. This paper proposes criteria for assessing advisory services based on a conceptual framework for analysing characteristics of advisory services as a component of the wider Agricultural Knowledge and Innovation System (AKIS). Using the example of the UK, we investigated characteristics pertaining to governance structures, capacity, management and advisory methods. Data were collected in an online survey of 80 agricultural advisory organisations. Findings showed that most criteria for functional advisory services were met: agricultural advisory organisations utilised diverse knowledge sources and cooperated to fill knowledge gaps; there was a stable workforce of advisors who received regular training; advisory organisations were flexible and adaptive; and all relevant advisory topics were covered. However, a number of client groups were not targeted by advisory organisations and some organisations used only a narrow range of advisory methods. The proposed criteria reflect a balance between a thorough assessment of a country’s advisory services and the typically limited time and budget available for regular evaluations. The criteria and associated proxy indicators should be fine-tuned to reflect the individual country’s situation, and quantitative survey data complemented by qualitative data.     

The impact of mining and smelting activities on property values: a study of Mount Isa city,Queensland, Australia

Much publicity has been given to the problem of high levels of environmental contaminants, most notably high blood lead concentration levels among children in the city of Mount Isa because of mining and smelting activities. The health impacts from mining‐related pollutants are now well documented. This includes published research being discussed in an editorial of the Medical Journal of Australia (see Munksgaard et al. 2010 ). On the other hand, negative impacts on property prices, although mentioned, have not been examined to date. This study rectifies this research gap. This study uses a hedonic property price approach to examine the impact of mining‐ and smelting‐related pollution on nearby property prices. The hypothesis is that those properties closer to the lead and copper smelters have lower property (house) prices than those farther away. The results of the study show that the marginal willingness to pay to be farther from the pollution source is AUS $13 947 per kilometre within the 4 km radius selected. The study has several policy implications, which are discussed briefly. We used ordinary least squares, geographically weighted regression, spatial error and spatial autoregressive or spatial lag models for this analysis.     

Does research performance explain the “leaky pipeline” in Indian academia? A study of agricultural and applied economics

This article documents the existence of a leaky pipeline based on complete enumeration of faculty in two large public academic networks: state agricultural universities and institutions of the Indian Council of Social Science Research. We then examine if there are gender differences in the quantity and quality of research publications of women relative to men that can explain this. As proxies for quality and visibility, we use several metrics, including the number of citations, h-index, i10 index, and Scimago rank of the journal in which the research is featured. A novel aspect of the analysis is the comparison of time paths of cumulative publications over career paths of men and women professors. Our analysis of research performance is based on scraping publicly-available data sources, including faculty and institutional websites, and google scholar pages, and represents one-third (and likely positively selected) of all faculty in these institutions. Our results suggest that women are disadvantaged in terms of number of publications during early career years, however, the disadvantage is mitigated with seniority and women perform equally well or even surpass men later in their careers. Women are more likely to write single-authored articles and have fewer collaborators than men, indicating that they do not access collaborative spaces as much, and are less networked than men. In spite of this, there is suggestive evidence that women are more quality conscious than men. This nuanced look at research productivity suggests the source of the leaky pipeline does not arise from differences in performance.     

Interdisciplinary Agricultural Research in Canada

The activities and accomplishments of agricultural economists conducting interdisciplinary research in association with other agricultural scientists in Canada are reviewed and evaluated. Agriculture and Agri-Food Canada instituted an interdisciplinary research program with the placement of agricultural economists at Research Centres in the early 1970s. University- and government-employed agricultural economists have produced a large number of important studies for the benefit of the agricultural industry in Canada. However, less than 3% of the articles published in this journal since its inception in 1952 report on interdisciplinary research. Interdisciplinary research in agriculture has been hampered by organizational weaknesses and inherent difficulties associated with conducting this type of research.     

Going Beyond Impact Factors: A Survey‐based Journal Ranking by Agricultural Economists

A consistent and comprehensive ranking of journals relevant for agricultural economists cannot rely on impact factors for at least two major reasons: (i) the scientific database by Thomson Reuters, on which the standard impact factor is based, includes only a very limited number of relevant journals; (ii) the standard impact factor cannot be compared across research fields of different sizes. Survey‐based journal rankings may overcome these problems. We report on such a survey‐based ranking initiated by the Agricultural Economics Associations of Germany and Austria. Results of the ranking and a classification of journals, i.e. a rating, are provided for 160 selected journals. Scientific quality is assessed by an index based on the researchers’ perception of the quality standards of each journal and of the quality of its published articles. The survey‐based ranking allows a much more comprehensive and consistent ranking than the impact factor, as specific agricultural economics journals can be directly compared with neighbouring economic and interdisciplinary journals to which agricultural economists submit their work. The low impact factors of core agricultural economics journals are put into perspective. The scientific quality of the top agricultural economics journals is assessed as being rather high and above most of the relevant interdisciplinary journals from agricultural and food sciences that are typically characterised by higher impact factors. Agricultural economists’ perceptions on the scientific quality of the journals vary more across journals than perceptions of their relevance.     

Report of the Managing Editor

2004 has been a good year for the Journal and the last under the Nottingham editorial team. The target of a four‐month average turnaround for submissions has been achieved for the second year in succession and record use has been made of the on‐line version of the JAE ‐which currently attracts around 165 full‐text paper downloads per month. The release of the 2003 citations data from the Institute of Scientific Information shows that JAE articles are cited more than ever before, although the change in the JAE's publication dates implemented in 2002 have inadvertently reduced its ‘impact factor’ score, which has slipped from 1^st to 7^th since 2001. Reversion to the original publication cycle will correct this apparent decline. On the other two measures JAE is ranked 2^nd and 3^rd in the Agricultural Economics and Policy category. Preparations are on‐going to ensure a smooth hand‐over of Editorship in April 2005, when Professor David Harvey and colleagues from the University of Newcastle upon Tyne take over the JAE. The handover will coincide with the adoption of an electronic submission and review system and a partnership with Blackwell Publishing.     

Who are Advisory Services Leaving Out? A Critical Reflection on ‘Hard to Reach’ Farmers

Although the Common Agricultural Policy of the European Union has broadened its objectives to integrate social issues, several hard-to-reach groups of farmers and workers continue to be ignored by advisory services and associated policies. Connecting with these groups has a strong potential to increase the economic and social cohesion of European agricultures. We interviewed over 1,000 farmers across Europe and identified features of these groups that are often overlooked by advisory services. We critically reflected on the social cohorts omitted from advisory services and how they could be better reached; they include farm labourers, new entrants or ‘career changers’, and later adopters. We clarify the different types of advisors in the advisory landscape, distinguishing between those who are linked to or independent from sales of inputs or technologies. We make concrete recommendations about how to engage advisors with hard-to-reach groups, with approaches suited to different national contexts of Agricultural Knowledge and Innovation Systems (AKIS); thus contributing to the ‘AKIS dimension of National Strategic Plans of the next Common Agricultural Policy, 2023–2027. We argue for the more effective use of advances in the social sciences through a better understanding of advice as social interaction which can bolster the inclusiveness of public policies.

Socio-Technical Scenarios as a Tool to Improve Farm Advisory Services

This article examines the use of the socio-technical scenarios (STSc) method to explore the future needs of farmers in the adoption of more sustainable farming practices. It also examines the changes needed for advisory services to meet those identified needs. It presents the results from four STSc workshops organised as part of the H2020 AgriLink project. Workshop participants (farmers, advisors, policymakers, researchers), jointly explored future changes towards more sustainable agricultural systems paying special attention to the role of advisory services in these transitions. Despite the diversity of national contexts, common results emerged concerning both the shortcomings of the current advisory systems and directions for improvement. Participants agreed that advising on single aspects would not achieve the required systemic changes; these would require more integrated advisory systems at different levels (improved cooperation and knowledge flow), supported by more consistent policies. We indeed identified discrepancies between policy expectations and the broader innovation context. Policies should facilitate the role of advisors in supporting farmers to adopt sustainable innovations, but more often they also create barriers for such innovations. Participants’ concrete recommendations for more farmer-centered advisory services illustrate the usefulness of the STSc to explore potential solutions to key problems in contemporary farm advisory systems.     

Designing a forest-energy policy to reduce forest fires in Galicia (Spain): A contingent valuation application

Recent issues of this journal have presented an interesting debate regarding forest fires in Galicia, Spain. This article proposes a forest-energy programme that will contribute to reducing the risk of forest fires in this Atlantic Region of Southern Europe. We apply the contingent valuation method to assess a programme whereby 10% of the electricity produced from coal, fuel oil and gas would be replaced by electricity generated in biomass power plants. The programme would begin implementation in 2005 and it would take 6 years (up to 2010) before we reach the 10% goal. The results show that Galician households are willing to pay a mean of 38 Euros per year. In addition, we have introduced an innovative procedure to detect protest responses related to the payment vehicle in a contingent valuation. Heckman's sample-selection procedure is used to analyse the WTP function.     

Economic Growth,Globalisation and Beer Consumption

We analyse the evolution of beer consumption between countries and over time. Historically, there have been major changes in beer consumption in the world. In recent times, per capita consumption has decreased in traditional beer drinking countries while it increased strongly in emerging economies. Recently, China has overtaken the US as the largest beer economy. A quantitative empirical analysis studies the relationships among economic growth, globalisation and beer consumption. The relationship between income and beer consumption has an inverse U‐shape. Beer consumption initially increases with rising incomes; but at higher levels of income beer consumption falls. Increased globalisation has contributed to a convergence in alcohol consumption patterns across countries. In countries that were originally beer drinking countries, the share of beer in total alcohol consumption reduced, while this is not the case in countries which traditionally drank mostly wine or spirits.     

CAP and Advisory Services: From Farm Advisory Systems to Innovation Support

Farm advisory services have become an important topic in the Common Agricultural Policy (CAP) of the European Union (EU). The aim of this article is to draw lessons from the implementation of the regulation and measures of the current 2014–2022 CAP in knowledge transfer and advisory services to contribute to debates about the future of farm advisory policies. Findings are based on two studies commissioned by the European Commission: an evaluation study implemented by a consortium of consultancies and researchers and a comparative analysis implemented in the frame of the H2020 research project AgriLink. The article first provides a historical perspective of the ‘knowledge and advice’ dimension of the CAP since 2007. We show a gradual transition towards greater flexibility of measures supporting innovation and knowledge flows. The professional status of farm advisors across European countries was more strongly acknowledged, offering new life-long training opportunities to advisors. However, the implementation of CAP’s advisory measures remains complex. As a result, the effects of these measures have been rather limited, with only few farmers reached overall. Fostering an inclusiveness of these measures remains an ongoing challenge for policymakers.
