The EU is a major player in the global wheat market. This paper examines the pricing behaviour of EU wheat exporters using a pricing‐to‐market (PTM) analysis. Wheat is an exemplary product for testing PTM theories as it is widely and frequently traded, and largely unbranded. We estimate the relationship between export unit values and exchange rates using quarterly panel data for 11 EU export destinations for 2000–2013. Results show that there is a meaningful long‐run relationship between export unit values and exchange rates, but there is little evidence of differential mark‐ups between EU export markets. Belarus and Iceland are exceptions where exporters from the EU appear to exercise local currency price stabilisation.  相似文献

Agricultural producers are increasingly required to adjust production practices to satisfy retailer, and ultimately consumer, preferences. This article highlights the option value that underlies decisions related to production technologies using the case of Michigan dairy farmers and recombinant bovine somatotropin (rbST). Welfare impacts were calculated for dairy producers when milk production systems which allowed the use of rbST were eliminated from the producer choice set. Those dairy producers using rbST just before its elimination realized a higher welfare loss than those not using the technology. However, significant welfare impacts were found for all dairy producers indicating that all producers valued the option to use this production technology.  相似文献

This paper examines the relationship between farm growth and participation in agri‐environmental schemes, using the example of meadow extensification schemes in Switzerland. As a result of small farm sizes in Swiss agriculture, theory would suggest that economies of scale are considerable for market production activities, so that for growing farms it would be rational to intensify. Configural frequency analysis is used to identify and describe combinations of farm size development and proportion of meadows placed under agri‐environmental schemes. In the Swiss case, growing farms are likely to reduce their participation, whereas shrinking farms have a growing share of their meadows under extensification schemes.  相似文献

Biofortified staple foods are currently being developed to reduce problems of micronutrient malnutrition among the poor. This partly involves use of genetic modification. Yet, relatively little is known about consumer acceptance of such second‐generation genetically modified (GM) foods in developing countries. Here, we analyse consumer attitudes towards provitamin A GM cassava in the north‐east of Brazil. Based on stated preference data, mean willingness to pay is estimated at 60–70% above market prices for traditional cassava. This is higher than the results from similar studies in developed countries, which is plausible given that micronutrient malnutrition is more severe in developing countries. GM foods with enhanced nutritive attributes seem to be well received by poor consumers. However, the results also suggest that acceptance would be still higher if provitamin A were introduced to cassava through conventional breeding. Some policy implications are discussed.  相似文献

We model welfare gains from efficient allocation of groundwater over space and time relative to the status quo policy of financial cost recovery. In order to promote political feasibility, an intertemporal compensation plan is devised that renders the reform Pareto-improving. Gainers from the reform finance the compensation in proportion to their benefits through a block-pricing scheme. For the Honolulu case, only 7% of the $441 million in gains to winners is needed to compensate losers from the reform. Future winners from the reform also repay the deficit created by the compensation package, much as state and local governments finance capital improvements.  相似文献

This article extends the multi‐period agri‐environmental contract model of Fraser (Journal of Agricultural Economics, Vol. 55 , (2004) pp. 525–540) to include a more realistic specification of the inter‐temporal penalties for non‐compliance, and therefore of the inter‐temporal moral hazard problem in agri‐environmental policy design. It is shown that a farmer has an unambiguous preference for cheating early over cheating late in the contract period based on differences in the expected cost of compliance. It is then shown how the principal can make use of this unambiguous preference to target monitoring resources intertemporally, and in so doing, to encourage full contract duration compliance.  相似文献

Pest-management technologies have had to adapt to address evolving pesticide resistance problems and changes in regulations driven by environmental and human health concerns. Integrated pest management, founded in the University of California, is an important example. Using California as a case study, this paper describes the post–World War II history of agricultural pest-management technology, documents the development and use of chemical pesticides, describes the role of public research, and measures the benefits and costs for five important commodities, emphasizing integrated pest management.  相似文献

This study examines the effect of tariff‐rate quota (TRQ) expansions as have emerged from the international trade negotiations that are designed to ensure market access for many sensitive agricultural products. We extend the existing models on tariff–quota equivalence to a TRQ system. Our theoretical finding indicates that the equivalence of domestic price between out‐quota tariff reduction and quota expansion depends on domestic producer's behavior and on the values of conjectural variation. An empirical spatial equilibrium model of international rice trade is used to examine the price and welfare impacts of replacing quota expansions with tariff reductions. Le présent article examine les répercussions de l’expansion des contingents tarifaires issue des négociations de commerce international pour assurer l’accès au marché de nombreux produits agricoles sensibles. Nous avons élargi les modèles existants d’équivalence entre les quotas et les tarifs à un système de contingents tarifaires. Nos résultats théoriques ont indiqué que l’équivalence de prix intérieur entre la diminution des tarifs hors contingent et l’expansion des contingents dépend du comportement du producteur national et de la valeur des variations conjecturales. Nous avons appliqué un modèle empirique d’équilibre spatial dans le commerce international du riz pour examiner les répercussions du remplacement de l’expansion des quotas par des réductions de tarifs sur le prix et le bien‐être.  相似文献

Intra‐industry trade (IIT) has become a widespread phenomenon with a growing role in international trade, though agricultural trade is usually neglected in empirical works. This article identifies the determinants of horizontal and vertical intra‐industry agri‐food trade between New Member States (NMS) and the EU‐27 in 1999–2010, by applying static and dynamic models with different specifications to panel data. Results show that IIT is mainly of a vertical nature in the NMS, though the majority of NMS export low quality agri‐food products to EU‐27 markets. Factor endowments are negatively related to agri‐food horizontal intra‐industry trade (HIIT), but positively to vertical intra‐industry trade (VIIT). Economic size is positively and significantly related to both types of IIT, while distance and IIT are found to be negatively related in both cases. Results also suggest that HIIT and VIIT are greater if a New Member State exports agri‐food products to another NMS while EU accession has had positive and significant impacts on both HIIT and VIIT, suggesting that economic integration fosters IIT.  相似文献

Two of the experimental methods used to estimate willingness‐to‐pay (WTP) for a non‐market good, the Becker‐DeGroot‐Marschak (BDM) mechanism and the non‐hypothetical choice experiment (nHCE) often lead to significantly different WTP estimates, complicating the choice between the methods. In Zambia the same group of researchers used both techniques to evaluate WTP for orange maize, which provides more vitamin A than other varieties. This provided an opportunity to analyse the sources of the difference. In the BDM experiment, one group of respondents was provided with more training opportunities than the other, and made higher bids. Accounting for lexicographic behaviour in the nHCE reduced the estimated WTP. These two design factors together resulted in a decrease in the WTP difference for orange maize (1,279–632 ZMK) although the difference remains statistically significant. More training was also shown to eliminate the effects of different orders in which maize varieties were presented.  相似文献

This article provides an empirical analysis of the impact of European Union (EU) private food safety standards on pesticide use and farm‐level productivity among small‐scale vegetable producers in Kenya. We apply an extended three‐stage damage control production framework, accounting for multiple endogeneity problems, to farm‐level data collected from a random cross‐sectional sample of 539 small‐scale producers. Estimation results show that farmers producing vegetables for the domestic market use significantly lower quantities of pesticides than do export farmers. However, contrary to findings elsewhere, the econometric evidence here shows that both domestic and export‐oriented vegetable farmers in Kenya use pesticides at levels below the economic optimum. The results also show that the adoption of standards by export farmers does not have any significant impact on total pesticide use. However, adopter categories are distinguishable in terms of types of pesticide used, i.e. adopters use safer pesticides based on World Health Organization (WHO) classification. The third‐stage structural revenue model results demonstrate that adoption of standards has a positive and significant impact on revenue raised in vegetable production. Nevertheless, farmers producing for the export market are indistinguishable from those producing for the domestic farmers in terms of the total revenue earned from producing vegetables during the rainy season, on a ‘per acre’ basis. Although standards can potentially prevent resource‐poor smallholders from maintaining their position in the lucrative export markets, they can also result in positive changes in the production systems of those small‐scale farmers who adopt it, as shown by these results.  相似文献

Canada has stringent regulations covering the release of new wheat varieties, but the United States has virtually no regulations in this area. Monsanto Co. developed genetically modified (GM) spring wheat for North America, and made a commitment to the U.S. industry to release this new technology simultaneously in both Canada and the United States, or not at all. The Canadian regulatory bias against new varieties acted as a veto against GM wheat and caused Monsanto to shelve the technology in both countries in 2004. Substantial economic rents were foregone in North America due to the rejection of this new technology.  相似文献

This paper summarises the findings of a study that examined the performance of low external input technology (LEIT) in three major projects. The projects promoted soil restoration (Honduras), soil and water conservation (Kenya) and IPM (Sri Lanka). The focus projects were large and well-managed and the study examined outcomes five or more years after project completion. An assessment of the utilisation, adaptation and abandonment of the technologies, found fairly consistent experiences that allow several general conclusions. In many instances LEIT makes important contributions to farm productivity. LEIT is not usefully categorised as labour-intensive, and the growing importance of hired labour makes it difficult to see LEITas a separate class of technology. Its uptake patterns are similar to those of conventional technology (with commercial incentives particularly important) and spontaneous diffusion of the technology is often less than expected. LEIT, on its own, makes only modest contributions to strengthening human and social capital. Implications for the promotion of LEIT and the development of farmer organisations are discussed.  相似文献

Intersectoral linkages are analysed using a CGE model based on a SAM constructed from Indian national accounts data for 1988–89. The model includes the rural non‐farm sector, public sector production and aspects of public policy. Evidence supports the arguments of Chakravarty (1987) and Ahluwalia (1986) regarding the importance of broad‐based agricultural development as opposed to increased production in the food sector alone aimed at achieving food self‐sufficiency.  相似文献

The recent literature on agricultural technology adoption shows that diffusion of new technologies varies significantly across space and time. Furthermore, puzzles exist about why some seemingly profitable technologies are not adopted, especially in livestock production. We employ a hazard or duration function to explain diffusion of crossbred-cow technology in a unique sample of Tanzania farmers. A farmer's adoption of crossbred technology depends positively on the proximity of his farm to other users, on his schooling, and on his access to credit and contact with extension agents.  相似文献

In this study, cross-country differences in the food processing industry's technology are investigated. A value-added function is estimated using panel data comprising of 13 developed countries and the 1975–95 period. Evidence of nonconstant returns to scale and differences in technology across countries is statistically significant. The United States is the leader in terms of the level of total factor productivity followed by Japan, Germany, France and Canada in that order. The growth rates and levels of productivity are inversely related, and the speed of productivity convergence is 2.6% per year. In addition to impacting future growth and international trade analyses, the study has implications for competitiveness of the food processing industry.  相似文献

This paper applies a semi‐parametric approach to estimating a generalised model of investments in heating installations. The results suggest that marginal costs of investments in heating installations increase quickly at small investment levels, whereas the increase slows down at higher investment levels. Therefore, standard parametric adjustment cost models are probably biased such that they underestimate the costs of small investments and overestimate the costs of large investments. Results also show that investments in heating installations are very responsive to changes in energy prices. Therefore, an energy tax may be an effective instrument to encourage investments in new energy‐saving heating installations.  相似文献

This article analyses determinants for 2001 farmland rental prices from 3,819 farms in Germany. Based on specification tests we estimate a general spatial model to account for both spatial relationships among rental prices of neighbouring farmers and spatially autocorrelated error terms. A €1 per hectare higher rental price in a farmer’s neighbourhood coincides with a €0.72 higher rental price paid by the farmer. The marginal incidence of EU per‐hectare payments paid for eligible arable crop land on rental rates amounts to €0.38 for each additional €1 of premium payments. Regional livestock density, which is indirectly influenced by different policies, is also a major determinant of rental prices. Results are confirmed by sensitivity analyses. Consequently, German farmland rental rates are heavily influenced by agricultural policy instruments and therefore, these policies exhibit substantial distributional effects.  相似文献

This article empirically models a strategic game of technology adoption of shuttle train grain elevators with information on location of the firm and its competitors. A spatial econometric model illustrates the role of spatial interdependence of rivals' decisions as well as agronomic and competitive variables on discrete adoption decisions. The analysis assesses equilibria conditions that characterize technology adoption, in this case of shuttle train adoption, and the results provide an explanation of shuttle train adoption decisions in the grain handling industry in which spatial competition is critical.  相似文献

Duration Analysis of Technological Adoption in Ethiopian Agriculture   总被引:1,自引:0,他引:1  
Duration analysis has been used to examine the impact of time‐varying and time‐invariant variables on the speed of adoption of fertiliser and herbicide by smallholder farmers in East and West Shewa in the central highlands of Ethiopia in the 25 years preceding 1996. The estimated models suggest that economic incentives were the most important determinants of the time farmers waited before adopting new technologies; traction power in the form of oxen and infrastructural factors (in particular proximity to markets) also appear to have been important influences, but less so than prices. Other agricultural inputs (area of farmland, labour, credit), extension services and farmers' personal characteristics (education, gender, age) appear to have had little, if any, effect on adoption behaviour. There is also evidence that the speed of adoption of herbicide, on both tef and wheat, was slower than that of fertiliser.  相似文献
