The purpose of the paper is to present an agricultural supply model for Scotland used to estimate regional changes in agricultural outputs due to the 2003 Common Agricultural Policy (CAP) reform. Supply functions were estimated for several farm types based on generalised trans-logarithmic multiproduct cost functions (Caves, Christensen and Tretheway, 1981). The data used for the estimation were an unbalanced panel dataset constructed using farm level data from the Scottish Government’s Farm Accounts Scheme (FAS) survey. Using the estimated supply adjustments, individual farm level responses to subsidy and price changes were aggregated using agricultural census weights to estimate the output changes for different regions

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.

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...

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...

In this paper the relative cost efficiency of Scottish farms is determined, and variables that explain this efficiency by farm type are identified and implications discussed. A panel dataset from the Farm Accounts Scheme (FAS) survey for the period 1997-2004 was used for the estimation. A cost efficiency indicator was measured using a fixed effect panel data regression. Further analysis, to explain the efficiency results, indicated the presence of important farm size and regional effects. However, other variables, whilst statistically significant, did not produce a consistent effect across the different farm types.

AN ANALYSIS OF MARKETING CHANNELS OF LOCAL FOOD IN SCOTLAND

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.

The new orientation of the Common Agriculture Policy encourages producers to respond to market forces. In addition, the public expect producers to contribute to a living countryside. Based on this context, the purpose of the paper is to discuss what other marketing alternatives exist for the promotion of mountain quality food products beyond labelling. This is done through the analyses of shelves and postal surveys to retailers, carried out as part of the EU project EuroMARC, which included information for Austria, France, Norway, Romania, Slovenia and UK (Scotland). The analysis concentrates on two product promotion aspects: display and store-promotion, and communication of product attributes. The results indicate that even without labelling policy there...

The specific purpose of this paper is to estimate the extent to which decoupled payments under the Single Payments Scheme (SPS) are being used (either explicitly or implicitly) in England to support the continuation of activities that were previously supported by area and headage payments. In the absence of a farm survey, the methodology consists of using information on farm accounts collected through England’s Farm Business Survey (FBS), to estimate a multi-output cost function differentiated by farm size and farm type. This cost function, calibrated to match regional prices in England, is used to estimate the level of cross-subsidisation in the first full year after implementation of the SPS (2005/06). Results indicate that cross-subsidisation was...

The purpose of this paper is to study the effect that the imminent reform in the European Union (EU) sugar regime may have on farm productivity in the United Kingdom (UK). We perform the analysis on a sample of sugar beet farms representative of all the UK sugar beet regions. To estimate the changes in productivity, we estimate a multi-output cost function representing the cropping part of the farm, which is the component that would be mostly affected by the sugar beet reform. We use this cost function to compute the new allocation of outputs and inputs after the changes in the sugar beet quota and price support. This are subsequently used to compute measures of total factor productivity. Our results show slight decreases in the productivity at the...

n the paper, we study price transmission from wholesale peanut prices to retail peanut butter prices. Using monthly data since 1984, we show that, while an increase in peanut prices is almost immediately transferred to peanut butter prices, it takes several months for a price decrease to be reflected in the peanut butter prices. Besides, the long term price transmission effect also appears to be symmetric. The observed short and long-term asymmetry is explained as a result of profit maximizing inventory management and/or some degree of market power in peanut processing.

This paper models the interaction of working (also called pipeline) and speculative commodity stocks. We model working inventories (i.e., raw material inventories carried by processors) based on Rameys (1989) model of inventories as factors of production, which allows us to represent storage under inter-temporal price backwardation, observed in commodity markets. We incorporate both speculative and working stocks in a simple model to analyze the interaction and to simulate the relationship between inter-temporal commodity price spreads and stocks. Our model replicates common price patters found in commodity markets.

The purpose of this paper is to study the price behaviour of fresh produce at the retail level of two leading supermarkets, Tesco and Sainsbury, with the purpose of gaining knowledge about their interaction. We focus the study on six products from the fresh fruits and vegetable group (i.e., tomatoes, Bramley’s apples, white cabbage, cucumbers, Iceberg lettuce and Round lettuce) due to the fact on the one hand it is a less complex supply chain (e.g., perishable product, less number of intermediaries) and on the other hand, because during the last 20 years the group has significantly evolved with supermarkets becoming the major players in the chain. The empirical methodology consisted of using Granger causality tests to establish the relationship between the...

The Scottish red meat industry is a major part of the Scottish agricultural economy and is known for producing high quality beef and lamb. Beef and lamb which are produced and processed in Scotland and according to a quality assured production specification, carry the EU ‘Protected Geographical Indications’ (PGI) name of ‘Scotch’. In addition, red meat in Scotland has to compete with high quality imported products (e.g., from Brazil or Argentina) or with meat from elsewhere in the United Kingdom. This paper focuses on the situation of Scotch beef and how differentiated it is in the eyes of consumers. For this purpose we use two years’ retailing data for Scotland (and by socio-economic group) from a major supermarket to estimate the conditional demand for...

In this paper the cost efficiency of Scottish farms is determined, variables that explain the relative cost efficiency by farm type are identified and implications discussed. A cost efficiency approach was selected as it can deal with farms producing multiple outputs (in contrast to production frontiers), and second because it can accommodate output constraints imposed by the Common Agricultural Policy (CAP). To estimate the stochastic cost frontier, a generalised multi-product translog cost function was estimated for five farm types: dairy, cereals and general cropping, cattle and sheep, specialist sheep and mixed farms. Eight farm outputs and four inputs were considered. The data for the estimation were drawn from the Farm Accounts Scheme (FAS) survey...

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...

If one observe aggregated cattle figures for Scotland for more than a century it is possible to perceive that that cattle numbers seem to react strongly to agricultural policy (e.g., livestock subsidies before 1973, UK becoming part to the European Community). The purpose the paper is to provide a regional view of this result, namely whether the same trend can be observed if the analysis is done by Scottish regions. For this purpose, we assembled a panel dataset for 11 Scottish regions for the period 1959 until 2008. We specialised the analysis on beef cattle. We use simple regression techniques to verify whether there have been changes in the regional shares of beef cattle and whether beef cattle numbers in the different regions tend to converge to a...
