A Metafrontier Analysis of Technical Efficiency of Selected European Agricultures AgEcon
Barnes, Andrew Peter; Revoredo-Giha, Cesar.
Technical efficiency refers to the situation where it is impossible for a firm to produce, with the given know-how, (1) a larger output from the same inputs or (2) the same output with less of one or more inputs without increasing the amount of other inputs. In practice, the interest is on the relative position in terms of efficiency of a particular firm with respect to others. Therefore, technical efficiency is characterised by the relationship between observed production and some ideal or potential production (Greene, 1993). Although the beginning of the efficiency work can be traced to the 1950s (Farrell, 1957), there have been a growing interest on its use in benchmarking performance, predominantly as a means of identifying best practice and improving...

A metafrontier approach to measuring technical efficiencies across the UK dairy sector AgEcon
Barnes, Andrew Peter; Revoredo-Giha, Cesar; Sauer, Johannes.
A regional approach is applied to measure technical efficiencies on dairy farms which employs the deterministic metafrontier approach. We construct six super regions for the UK, i.e. Eastern, Western, Northern England, Wales, Scotland and Northern Ireland. Data are collected through three different administrative systems, all be it under the same FADN guidance. We find for dairy farming comparative indicators of performance in all three data sets. The stochastic frontier approach is applied to construct 6 regional frontiers and a pooled (UK) dataset for comparison. A likelihood ratio test rejects the null hypothesis that these regions operate under a common frontier which may indicate bias in previous attempts to measure dairying efficiency at the country...

A structural change analysis of the cost efficiency of farms in Scotland 1989-2008 AgEcon
Revoredo-Giha, Cesar; Leat, Philip M.K.; Milne, Catherine E..
One of the aims of the reform of the Common Agricultural Policy (CAP) is to increase the competitiveness of farmers through increasing their exposure to markets. An aspect of competitiveness is the gains in economic efficiency. Thus, the purpose of this paper is to estimate indicators of farm efficiency for the period 1989 to 2008 by farm type and to analyse what the effect on efficiency of changes in the CAP has been. In terms of the methodology, the information used comes from the Scottish Farm Account Scheme (FAS) survey, which allows us to assemble panel dataset and to construct cost efficiency indicators. The results indicate while mixed farms and lowland farms have maintain their levels of efficiency. LFA farms have seen their efficiency reduced...

Agri-food chain relationships in Europe – empirical evidence and implications for sector competitiveness AgEcon
Fischer, Christian; Hartmann, Monika; Reynolds, Nikolai; Leat, Philip M.K.; Revoredo-Giha, Cesar; Henchion, Maeve M.; Gracia, Azucena.
The roles of business relationships in selected European agri-food chains are analysed. Using survey data from 1,442 farmers, food processors and retailers in two commodity sectors (meat and cereals) and across six different EU countries, we test the empirical relevance of several theory-based determinants influencing the choice of relationship type and the sustainability of inter-enterprise relationships. This is undertaken for the overall dataset and separately for different chain stages (farmer-processor versus the processor-retailer relationships), commodities and individual countries. Overall, we find that sector and enterprise-specific determinants seem to influence the choice of a certain relationship type while chain-internal, dyadic factors affect...

Agri-food supply chains and sustainability-related issues: evidence from across the Scottish agri-food economy AgEcon
Leat, Philip M.K.; Lamprinopoulou-Kranis, Chrysa; Revoredo-Giha, Cesar; Kupiec-Teahan, Beata.
This paper examines the influence of agri-food supply chains on the sustainability-related activities and decisions of Scottish farmers, as well as the treatment of sustainability issues by food processors and retailers themselves. It is based on 8 whole chain case studies covering some of Scotland’s major agricultural products. The cases identify differing levels of understanding and activities related to sustainability, but widespread acknowledgement that sustainability involves the development of chains within which all parties can achieve acceptable profits. Indeed, collaborative supply chains, which seek improved economic performance, frequently assist environmental and social sustainability. The main drivers of sustainability are found to be the cost...

An analysis of Marketing Channels of Local Food in Scotland AgEcon
Revoredo-Giha, Cesar; Watts, D.; Leat, Philip M.K..
Local food and its possibilities for addressing sustainable regional growth, food availability, accessibility and affordability has received considerable attention in the discussion on and development of the National Food Policy in Scotland. In terms of methodology, the paper continues the analysis of the local food database for Scotland constructed in Watts et al (2010) by exploring the marketing outlets used by the local food enterprises. This subject is important because it may provide information about the degree of entrepreneurship of the involved firms.

An Analysis of the Consumption of Sausages in Scotland using Supermarket Data AgEcon
Revoredo-Giha, Cesar; Kupiec-Teahan, Beata; Wrieden, Wendy; Davis, Victoria; Milne, Anne; Leat, Philip M.K..
This paper addresses consumers’ choices by looking into: current food choices made by different socio-economic groups; price barriers for diet improvement; and ways in which marketing may affect product choice. The study seeks: first, to analyze the differences in consumption of sausages of different nutritional composition among different socio-demographic and lifestage groups; and second, to measure whether it is possible to improve diet quality without affecting household expenditure. Sausages represent a relatively high proportion of red and processed meat purchases in Scotland, contributing significantly to the fat and sodium in the Scottish diet. The data used consisted of two-years of weekly information from a top-4, UK supermarket. The results...

ANALYSIS OF THE IMPACT ON UK SUGAR PRODUCTION EFFICIENCY OF REFORMING THE EU SUGAR REGIME AgEcon
Renwick, Alan W.; Revoredo-Giha, Cesar.
The purpose of the paper is examining the potential implications for the UK sugar beet sector of the EU sugar regime reform. Although the reform has yet to be formalised, the initial proposals centre on price and quota cuts. Using panel data from the Farm Business Survey for England, the paper estimates two cost functions: one for the sugar enterprise and another for the cropping part of the farm (i.e., excludes any livestock enterprise) and use them to analyse the impacts on profitability and costs of three possible reform scenarios: a 25 per cent cut in UK quota, a 25 per cent cut in price, a 40 per cent cut in price. The results show that the largest gains in terms of economic efficiency would be achieved under the 40 per cent price cut; however, the...

Bread Prices, Consumption and Nutrition Implications for Scotland: A Regional Analysis Using Supermarket Scanner Data AgEcon
Revoredo-Giha, Cesar; Lamprinopoulou-Kranis, Chrysa; Toma, Luiza; Leat, Philip M.K.; Kupiec-Teahan, Beata; Cacciolatti, Luca.
The recent rise in food prices has increased the concern about the choice of a healthy food basket, especially in the context of the discussion around the formulation of a National Food Policy for Scotland. This concern has brought back the interest in the price and expenditure demand systems as they provide information about consumers’ food decisions. The paper focuses on the consumption of brown and white bread, as they are the most typical ways of cereals use in the UK and nutritionists recommend the consumption of wholemeal or brown bread in contraposition to white bread as part of an appropriate diet due to its health benefits. This paper aims to answer whether changes in bread prices affect the quantity and composition of the Scottish demand for...

Business Relationships and B2B Communication in Selected European Agri-food Chains – First Empirical Evidence AgEcon
Fischer, Christian; Hartmann, Monika; Bavorova, Miroslava; Hockmann, Heinrich; Suvanto, Hannele; Viitaharju, Leena; Leat, Philip M.K.; Revoredo-Giha, Cesar; Henchion, Maeve M.; McGee, Claire; Dybowski, Grzegorz; Kobuszynska, Mira.
The roles of business relationships and B2B communication in selected European agri-food chains are analyzed. Using survey data from 1,026 farmers, food processors and retailers in two commodity sectors (meat and cereals) and five different EU countries (Germany, United Kingdom, Ireland, Finland, Poland), we test the empirical relevance of several theory-based determinants of relationship goodness. This is undertaken for the overall dataset and separately for different supply chain stages (farmer-processor versus the processor-retailer relationship) and for the individual countries. The estimation results, derived from structural equation modeling, suggest that the most important contributor to good business relationships is effective communication, with...

Can Rank-Order Tournaments Improve Efficiency of Quality Differentiated Crop Markets Under Marketing Loan Program Operation? The Case of U.S. Peanuts. AgEcon
Nadolnyak, Denis A.; Fletcher, Stanley M.; Revoredo-Giha, Cesar.
In the paper, alternative contractual arrangements between crop producers and processors are evaluated with a view of addressing the major issues present in peanut markets in the U.S., the major EU supplier of high quality peanuts. The issues are the thinness of the spot markets and the absence of quality premiums, both of which impair market efficiency. Results indicate that introducing contracts with a system of quality differentials creates incentives for producer self-selection to participate in the post harvest cash market. Moreover, in the presence of sufficiently high common production risk, tournament contracts are more efficient and preferred by the producers than the standard fixed premium schedules.
