The Impact of Foot and Mouth Disease on the Price of Beef The 2001 Foot and Mouth Disease (FMD) outbreak in the UK had many economic, social and personal impacts. One of the direct economic effects of the FMD outbreak arose from the manner in which livestock was marketed following restrictions placed on livestock movements. Farmers were restricted to selling their finished livestock on a deadweight basis to abattoirs, and the processing/marketing sector incurred increased costs. We show how, from a theoretical perspective, an increase in marketing costs can simultaneously lead to a rise in the retail price and a fall in the farm gate price. We then test this theory by examining the impact of the FMD outbreak on the price of beef at the retail and farm gate levels by analysing the differential or ‘marketing margin’ between farm gate and retail prices. Results show that the average marketing margin increased by 14pAg (3.1 per cent) following the FMD outbreak when compared with the pre FMD period. The estimated cost of this price differential to the UK beef industry is £130m between March 2001 and October 2002. This equates to a loss of £56m to beef farmers and implies increased processing/marketing costs of £74m to the downstream industry and ultimately consumers. L‘ impact de la fièvre aphteuse sur le prix du b?uf Les conséquences de l'épidémie de fièvre aphteuse qui a éclaté en Grande‐Bretagne en 2001 ont été profondes, à la fois économiques, sociales et individuelles. L'un des effets économiques directs a trouvé son origine dans les restrictions apportées aux transports de bétail. Les agriculteurs ont été empêchés de vendre directement en vif aux abattoirs leurs animaux terminés. Cela a coûté cher aux transformateurs et à la distribution. On montre ici, d'abord d'un point de vue theorique, comment l' accroissement des coûts de transformation a pu, à la fois, faire augmenter les prix de détail, et diminuer les prix au producteur. La théorie est ensuite testée, à partir de l'évolution, depuis l' apparition de la fièvre aphteuse, des prix du bceuf sur pied et au détail, ainsi que des marges de distribution. On arrive ainsi à montrer que la marge de commercialisation moyenne, c'est‐à‐dire la différence entre le prix a la ferme et le prix de détail, s'est accrue de 14 centimes par kg (3,1%) après l' apparition de la fièvre aphteuse, par comparaison à ce qu'elle était avant. Le coût total estimé de ce différentiel de prix représente 130 millions de livres pour la filière bceuf entre mars 2001 et octobre 2002. Ce coût aura été couvert par une perte de 56 millions de livres pour les agriculteurs, et un surcoût net de l'industrie de transformation, qui a été passé au consommateur, pour un montant de 74 millions de livres. Die Auswirkung der Maul‐ und Klauenseuche auf den Rindfleischpreis Der Ausbruch der Maul‐ und Klauenseuche (MKS) im Jahr 2001 in Großbritannien zog zahlreiche wirtschaftliche, soziale und persönliche Auswirkungen nach sich. Eine der direkten wirtschaftlichen Auswirkungen ergab sich daraus, wie Vieh gemäß der veränderten Viehvermarktung in Folge der Einschränkungen beim Tiertransport verkauft wurde. Die Landwirte durften ihr Schlachtvieh nur auf Grundlage des Schlachtgewichtspreises an Schlachthöfe verkaufen, und im Sektor Weiterverarbeitung/Vermarktung kam es zu höheren Kosten. Wir zeigen auf, wie vom theoretischen Blickwinkel aus höhere Vertriebskosten gleichzeitig zu einem Anstieg des Einzelhandelspreises sowie zu einem niedrigeren Erzeugerpreis führen können. Wir überprüfen diese Theorie, indent wir die Auswirkung des MKS‐Ausbruchs auf den Einzelhandelspreis und den Erzeugerpreis für Rindfleisch durch Bestimmung des Differenzials oder der “Marktspanne” zwischen den beiden Preisen untersuchen. Die Ergebnisse belegen, dass die durchschnittliche Spanne nach dem MKS‐Ausbruch im Vergleich zur Spanne aus der Zeit vor MKS urn 0,14 britische Pfund pro kg (3,1%) angestiegen ist. Die geschätzten Kosten dieses Preisdifferenzials für die britische Rindfleischindustrie belaufen sich für die Zeit zwischen Marz 2001 und Oktober 2002 auf 130 Millionen britische Pfund. Dies bedeutet einen Verlust in Höhe von 56 Millionen britischen Pfund für Bullenmastbetriebe und impliziert einen Kostenanstieg im Bereich Weiterverarbeitung/Vermarktung in Höhe von 74 Millionen britischen Pfund fur weiterverarbeitende Industrien und damit letztlich für den Verbraucher.  相似文献

Economists and veterinarians use similar approaches to analyse animal health threats, but veterinarians are concerned primarily with providing practical guidelines to peers and/or policy‐makers, while economists focus more on understanding the benefits to society as a whole and often provide only general guidelines to policy‐makers and little specific direction to practicing veterinarians. Despite the benefits of working together, differences in perspective and analytical approach often cause economists and veterinarians to struggle in dialogue and to lose some of the mutual gains that could be achieved through collaboration. This article discusses the use of economics in animal health management, identifies several useful literature reviews, and analyses a number of recent studies to explore the advantages and disadvantages of different conceptual and methodological approaches.  相似文献

Re‐emergence of the bluetongue disease in Europe poses a continuous threat to European livestock production. Large‐scale vaccination is the most effective intervention to control virus spread. Compared to command‐and‐control approaches, voluntary vaccination approaches can be effective at lower costs, provided that farmers are willing to participate. We use a discrete choice experiment to estimate the preferences for vaccination scheme attributes, accounting for preference heterogeneity via an integrated choice and latent variable approach. In designing livestock disease control schemes, it is often argued that governments should use financial, incentive‐based policy instruments to compensate farmers for externalities, assuming they act in rational self‐interest. Our results suggest that in addition to economic motives, farmers can have intrinsic or social motives to invest in livestock disease control. Implications for the effectiveness of providing subsidy or information to motivate voluntary participation are discussed.  相似文献

This article examines the expansion of the soybean complex in South America and the role of Chinese firms in expanding their presence in different sectors of the oilseed complex. The growth in trade relations between the two parties has been built on the export of primary commodities from South America and the import of Chinese manufactures—a trade pattern that reproduces core‐periphery dynamics identified by dependency theory scholars. Of particular importance in this bilateral trade is soybean, a crop that has been consolidated as the main export for several South American countries, fuelled by growing demand from China. This article explores China's role in the global political economy as a key agri‐business player and the implications for new relations of dependency by studying the strategies deployed by Chinese firms to increase their influence in the governance of the soybean nexus.  相似文献

Invasive pests and diseases in trees impose a range of costs on society related to reductions in timber values, impacts on recreational opportunities and effects on forest biodiversity. These costs need to be considered when assessing control options and developing public policy. We investigate the preferences and willingness to pay of the UK general public for a range of forest disease control measures using a choice experiment with a sample of 605 people. Respondents were relatively well informed about general tree disease‐related issues, such as causes and general measures to minimise the risk of disease spread. They were less knowledgeable about specific tree diseases, with Dutch elm disease and chalara ash dieback being the most well known. We find that disease control programmes in publicly‐owned forests and forests owned by charitable trusts are more likely to be supported by the public than equivalent control programmes in privately‐owned and/or commercial forests. The nature of scientific uncertainty about diseases does not affect peoples’ preferences for disease control measures significantly. Higher respondent income, greater ex‐ante knowledge about tree diseases, and more frequent visits to forests are correlated with greater willingness to support publicly‐funded tree disease control programmes in forests. Better knowledge about tree diseases also improves the clarity of respondents’ choices. We find a negative sentiment against some disease control measures, such as clear felling of a forest, and chemical or biocide spraying. We conclude that there is significant public support for part‐financing forest disease control policies in the UK, but that this is conditional on forest ownership and the type of control measures used.  相似文献

Political economy approaches to analysing the efficiency of rural financial markets have focused on the role of power and social relations. Neo-classical institutional economics, on the other hand, has used information and transaction costs to explain performance. Recognizing the limitations of both approaches, this paper presents an alternative that focuses on the institutional form of financial intermediaries, that is, the governance structure of rules, monitoring and enforcement mechanisms that enable them to operate. This structure is supported by both formal and informal rules, norms and sanctions. As a result, the ways in which transaction costs are affected by governance structures can be identified and the embeddedness of financial intermediaries in social relations can be theorized. The application of this approach in Central Kenya demonstrates the insights that it offers into explaining borrower preferences in the financial market.  相似文献

Several complicating issues arise in evaluating the returns to research into varietal improvements for perennial crops compared with annual crops. We elucidate and address these issues in the context of a case study of research aiming to develop varieties that are resistant to Pierce's disease (PD) of grapevines. PD imposes costs of over $100 million per year on the California grape industry, even with public PD control programs in place. Research projects to develop PD resistant varieties of grapevines are at various stages of completion. We describe the economic problems posed by PD, document the research programs undertaken to address the disease and present an economic assessment of the returns to the investment, which are conditional on other policies. Using a simulation model of the market for California winegrapes, we estimate the benefits from research, development and adoption of PD‐resistant vines as ranging from $4 million to $129 million annually over a 50‐year horizon, depending on the length of the R&D lag and the rate of adoption. In addition to these specific quantitative results the paper offers insight into the broader question of economic evaluation of damage‐mitigation technology for perennial crops.  相似文献

This paper estimates the impact of trypanosomiasis on crop-livestock production, economic loss and poverty in Ethiopia. We use unique panel data to estimate how the disease affects livestock deaths, production costs and crop production. We then use these estimates to evaluate the disease's total economic loss and its implications on poverty in the study districts and the country. Estimates of the fixed effect regression models indicate that trypanosomiasis increases the value of livestock deaths by 33% and production costs by 63%. Crop production decreases by 14% when trypanosomiasis and oxen death coexist. We estimate that the direct economic loss is about US$58,300 per annum in the study districts. The estimated countrywide economic loss is about US$94 million per annum. Had the government prevented this economic loss and invested it in social protection programmes, it could have lifted about 9000 people in the study districts and about 200,000 people in the country above the national poverty line per annum. These findings indicate that trypanosomiasis remains a major production constraint. Controlling the disease appears to be pro-poor, calling for more policy attention.  相似文献

Consumers’ attitudes, perceptions, personalities and motives play important roles in shaping their food choices. These factors are not fully observed by analysts, so they should be treated as latent variables. A number of economic studies treat such variables as direct measures of consumers’ food choice behaviour, even though this might introduce measurement error and endogeneity bias. We investigate the latent link between consumers’ preferences and food choice motives (FCMs) in an African context. We use an integrated choice and latent variable (ICLV) model specification for data analysis to recognise the latent nature of the FCMs and address the measurement and bias problems. The data originate from an incentivised discrete choice experiment conducted in Kenya to elicit consumers’ preferences for insect‐based foods. Our findings show that consumers’ preferences and choices are influenced by their latent motivational orientation. The results illustrate the benefit of the ICLV approach in accounting for consumers’ latent preference constructs in food choice and valuation research.  相似文献

This paper applies cointegration techniques to a model of induced innovation based on the two-stage constant elasticity of substitution (CES) production function. This approach results in direct tests of the inducement hypothesis, which are applied to data for South African commercial agriculture for the period 1947–1991. South African data is used because the policy changes have been substantial enough that the factor and price ratios have turning-points, rather than being monotonie. The time series properties of the variables are checked, cointegration is established, and an error correction model (ECM) constructed, allowing factor substitution to be separated from technological change. Finally, the ECM formulation is subjected to causality tests, which show that both the factor price ratios and R&D and extension expenditures are Granger-prior to the factor-saving biases of technological change. Thus, each stage of the analysis corroborates the inducement hypothesis. However, straightforward price-inducement is only part of the explanation of changes in factor ratios. Policy-induced innovation, in response to tax concessions and subsidised credit, is also present.  相似文献
