This paper examines the relationships among maize prices for four countries to determine if newly emerging exporters, Brazil and Ukraine, influence the international price of maize. Our work focuses on each market's participation in the price discovery process rather than trying to determine a price leader. We find that the United States plays the largest role in price discovery, followed by Argentina, Brazil, and Ukraine. We also search for export thresholds and find that Ukraine's contribution to price discovery rises slightly when an export threshold of 2.3 million tons is reached. No export thresholds were found for Brazil. Export thresholds for Argentina were found but only have a minor impact on price relationships. We also found that price relationships vary considerably across seasons of the year.  相似文献

Recent EU legislation will require Member States to ensure that farm advice which is supported by EU funding is impartial. In this article we present the findings of an online workshop which asked whether this should be a priority for European advisory supports within the Common Agricultural Policy. The answer was ‘no’. At the workshop, results of AgriLink were presented for discussion with international experts. These results highlighted major pitfalls for setting the boundaries of independent advice. Participants from Europe and North America agreed that ‘impartial’ advisors providing or selling only advice are rare in many contexts. Key organisations offering farm advice in many European countries, such as farmers’ cooperatives, often have established relationships with commercial suppliers. Being apparently independent from industry is also not sufficient for ensuring that advice addresses societal issues. Farmers’ choice for advice is more likely to reflect established trusted relationships than the ‘impartiality’ of the advisor. Workshop participants instead argued that policies should focus on increasing transparency (revealing vested interests); investing in ‘back office’ activities to ensure that advisors have access to reliable and relevant evidence; and ensuring that the full range of EU farmers have access to professional advice.  相似文献

In the United States, 35% of the forestland is owned by family forest owners with approximately 0.2% of this land reported to be enrolled in a forest certification system. The current study was conducted to provide insights into factors influencing family forest owners’ decisions to certify their lands. The bivariate probit model with sample selection results suggests that receiving professional advice regarding the forestlands and having a written management or stewardship plan had the highest positive marginal effects on awareness of certification programs and participation in these programs. Non-timber objectives had negative marginal effects on awareness of certification programs.  相似文献

Collective action through farmer groups can be an important strategy for smallholders to remain competitive in rapidly changing markets. Previous research has analysed determinants of farmer participation in groups, equating participation with group membership. However, within groups the commitment of members can vary, as marginal benefits and costs are not the same for all individuals, and opportunities to free‐ride exist. Low participation in collective activities may reduce the ability of groups to provide useful services to its members. This article investigates determinants of member participation intensity, using the example of farmer groups in Kenya. The role of individual and group characteristics is analysed with survey data and regression models. Previous benefits that members received through the group positively influence their intensity of participation in group meetings and collective marketing, suggesting that reciprocity motives play a role. Low participation can mostly be attributed to structural and institutional conditions, such as group size and the timing of payments for collective product sales. More diversified farmers are less likely to sell collectively when group marketing activities only concentrate on one particular commodity. Since smallholders are often highly diversified, the focus of farmer groups should also be broadened. Further policy implications are discussed.  相似文献

Although preserving soil health is essential for sustainability, over the last decade, there has been a significant increase in soil degradation in the European Union (EU) and, based on available information, this trend will not reverse in the long run. While the Union has adopted ambitious policy objectives addressing soil threats, there is not to date an EU soil-specific legislation, but various aspects of soil protection are scattered across many EU policy areas. This paper contributes to evaluating the status of soil protection within the EU environmental legislation, by creating an inventory of the relevant provisions and analyzing their features. It emerges that soil threats are not comprehensively regulated by the EU legislator and soil protection looks like the by-product of several provisions which mainly set preventive, qualitative and non strictly binding measures.  相似文献

This article compares contract farming with share tenancy, another labour regime in which smallholder farmers are bound by contract to deliver produce to another, usually more powerful party. Based on research in the Javanese village of Kaliloro, we explore contracting and sharecropping as labour regimes, each with their own specific mechanisms of surplus transfer from producers to non-producers. The cases compared are sharecropping of irrigated rice, contract farming of watermelon, and contract farming of poultry. There are important differences in how labour inputs are organized, how decisions are made, how costs are divided between landowner/contractor and farmer, and in the mechanisms of surplus transfer between the contracting parties. Exploring these differences allows us to understand and compare the role of the two labour regimes in the penetration of capital into the rural economy. Neither contract farming nor share tenancy are in themselves “win-win” or “win-lose” relationships, good or bad for small-scale cultivators. The actual balance of burdens and benefits—often contravening the provisions of written contracts or state regulation—is determined by power relations between the contracting parties.  相似文献

The data from long-term management and cropping systems experiments are needed to assess changes in soil quality, organic carbon pool, and agronomic sustainability. Thus, a 13-year-old soil fertility management experiment was used to assess the impact of crop residues carbon (C) inputs on SOC stock in a rainfed groundnut (Arachis hypogeae L.)–fingermillet (Eleusine coracana (L.) Gaertn) rotation in semiarid alfisol. The application of farmyard manure (FYM) alone or in a combination with chemical fertilizers contributed to higher amounts of C inputs and subsequently to build up a higher SOC pool. Application of 10?Mg?ha?1 of FYM and a recommended dose of chemical fertilizer (25:21.8:20.7 and 50:21.8:20.7?kg?N, P, K ha?1 for groundnut and fingermillet, respectively) increased soil SOC pool by 41.2% to 73.0?Mg?ha?1 with an increase of 9.3?Mg?ha?1 over 13 years. Both SOC pool and rates of its sequestration were positively correlated with cumulative C input and sustainable yield index. A minimal input of 1.62?Mg?C?ha?1?yr?1 is needed to maintain SOC pool at the antecedent level. Balanced application of NPK fertilizers is needed to reduce and reverse the depletion of SOC pool.  相似文献

We examine the firm‐specific determinants of technical efficiency in Australian mining companies using data envelopment analysis (DEA). To do so, we employ panel data sourced from individual mining companies listed on the Australian Securities Exchange (ASX) over the period 2010–2014. To ensure valid statistical inference in the presence of serial correlation between DEA efficiency scores, we apply Simar and Wilson's two‐stage bootstrap method. We find that ownership concentration, firm size, firm age, product portfolio, product diversification and growth status significantly contribute to efficiency gains. However, other firm‐specific factors, such as capacity utilisation, financial risk and overseas operations appear to have limited impact on the technical efficiency of mining firms.  相似文献

The 2005–8 food crisis was a shock to political elites, but in some respects the situation was normal. Food policies are failing to respond adequately to the squeeze on land, people, health and environment. Strong evidence of systems failure and stress, termed here New Fundamentals, ought to reframe twenty‐first century food politics and effort. Yet so far, international discourse is too often narrow and technical. The paper suggests that 2005–8 reinforced how the dominant twentieth century productionist policy paradigm is running out of steam. This assumed that producing more food would resolve social problems. Yet distortions in markets, access and culture remain. At national and international levels of governance, despite realization of the enormity of the challenge ahead, there is still a belief in slow incremental change.  相似文献

The establishment of the Economic and Monetary Union was expected to determine price convergence in the market of the European Union, leading to the equilibrium theorized by the law of one price. This article investigates prices convergence in the coffee market among European importers. Coffee is not only a tradable and traded good, but also one of the most valuable traded commodities. We account for different qualities of coffee in a hedonic regression model, which isolate and remove the effects of factors that might affect price dispersion. Adjusted import prices result to be significantly different between European Member States, and do not support the hypothesis of a deepening European market integration.  相似文献

This paper uses a randomized survey instrument to study the impact of African Swine Fever (ASF) information on Chinese consumers’ preference for pork attributes and purchases during the recent peak of the ASF pandemic in 2019. We study consumers’ preference for pork attributes including brand, meat texture and taste, quality safety assurance, and traceability under different information treatments. Results show that the willingness to pay (WTP) for quality safety assurance is the highest, followed by brands and traceability systems, and the WTP is lowest for good taste. We show that providing detailed ASF information substantially changes consumer preference by altering the relative importance of pork attributes and price sensitivity, which enables consumers to focus more on safety-related attributes while paying less attention to price and taste attributes. Furthermore, we find that a higher belief in the future of ASF occurrence reduces the frequency of purchases marginally but does not significantly influence for amount per purchase and the total purchase amount.  相似文献

In this article we assess the diversity of sources of advice identified by 678 adopters, 295 non-adopters and 107 droppers (or dis-adopters, who have ceased or reduced the use) of agricultural innovations across 13 European countries. For most innovations, the volume and composition of advisory supports (e.g. public advisory services, farm business organisations, NGOs, research and development sector, other farmers), at the whole farm level were similar between adopters, non-adopters and droppers. However, there were significant differences in relation to specific innovations. Farmers adopting digital technologies, soil-improving cropping systems, and common management of natural resources identified more diverse sources when assessing innovations, suggesting that more diverse advisory support supported successful implementation. For new on-farm activities, non-adopters had more varied sources of advice than adopters. This demonstrates that non-adoption can be a well-informed decision. Droppers typically identified fewer sources of advice on an innovation than adopters, particularly in the later stages of the innovation process, suggesting that lack of advice impeded successful implementation. The findings suggest that public funding for advisory services could usefully target emergent gaps: to support the provision of up-to-date advice on topics to farmers who have difficulty accessing advice, and to prevent unnecessary dropping by supporting the implementation of innovations.  相似文献

This paper applies a convention theory (CT) approach to the analysis of labour management systems in African large‐scale farming. The reconstruction of previous analyses of high‐value crop production on large‐scale farms in Africa in terms of CT suggests that, since 1980–95, labour management has moved from a ‘domestic’ to a ‘market’ system. However, data collected by the authors from a sample of 11 large‐scale rose farms in Kenya in 2011 (covering around 20% of national output) points to the adoption of systems that, in CT terms, combine ‘industrial’ and ‘civic’ elements. The paper concludes by suggesting a series of hypotheses that might explain this trend.  相似文献

In recent years, the densely populated region around the burgeoning city of Kano in northern Nigeria has been the focus of much academic enquiry into the links between vegetation modification and fuelwood production and consumption. While many scholars have praised the socio-economic and ecological sustainability of Kano's rural–urban interface, arguing that indigenous agro-forestry systems will continue to resist urban fuelwood pressures for many years to come, other less optimistic observers have warned that exposure to a rapidly changing world economy is challenging traditional resource management systems like never before. Focusing on the case of Kano and its resource hinterlands, recent field-based evidence presented in this paper suggests that the latter supposition may be gaining increasing currency. In peri-urban regions, the rising prices of kerosene and other petroleum-based domestic fuels, coupled with the economic knock-on effects of a current petro-boom, are making fuelwood a much more attractive alternative as a domestic fuel choice. As lower and middle-income households shift away from commercial petroleum-based energy sources in favour of cheaper and more readily available biomass alternatives, it may be placing increased pressure on woodland resources and Kano's surrounding rural ecology: in the hinterlands of the city, local perceptions of research informants suggest that deteriorating economic conditions have driven some individuals to ‘step up’ fuelwood production to meet rising peri-urban demands. Although the intention of the paper is not to perpetuate crisis narratives or to suggest that fuelwood demand is causing runaway deforestation, the evidence presented does suggest that as conventional fuels become progressively more expensive, the poorest and most disadvantaged households may find it increasingly challenging to meet their basic energy needs.  相似文献

This study explores the effect of a health involvement manipulation on food choices and how food choices are influenced by front-of-pack nutrition labels. The results show that without health involvement, choice was significantly affected by both nutrition labels and product type, but the product choice with health involvement was affected only by whether the product was selected as the healthier one in the involvement manipulation stage. Moreover, selection of the healthiest product during the manipulation stage was affected by the product type but not the front-of-pack (FOP) labels, potentially because participants relied on their own knowledge or the product perception to assess the healthiness of the product rather than the label information. The implication is that consumers seem to behave differently when pushed into a “choose healthy” state of mind, and their reliance on label information to assess product healthiness may be product and context dependent.  相似文献

While the recent global financial crisis heightened awareness of the linkages between global financial capital and urban spatial pattern, the timing of urban development – largely thought to be market driven – is not fully understood. Parcel-level studies of urban land-use change, which often use hazard models to investigate if and when development occurs, offer an opportunity to juxtapose the extent to which decisions to develop individual plots of farmland into housing are driven by market forces, the unique characteristics of the land and its intraurban location, or policies such as transportation infrastructure and municipal annexation. Using residential completion data in the Phoenix, Arizona region from 1992 to 2014, a period of dramatic commodity, fuel, and home price swings, and land cover imagery, we develop a parcel-level hazard model to gauge the relative impacts of market, policy, and place-based drivers of land change. We find limited evidence of induced development associated with freeway planning, that annexation and development are closely linked and moreso during economic booms, high fuel prices spur development in the region's core, and agricultural and urban land rents affect the timing of development. This study advances our understanding of development decision- making, policy impacts, and urban land-use change modeling and provides an empirical connection between local and global drivers of Greenfield development.  相似文献

The most contentious international trade issues currently arise not from traditional producer requests for protection, but as a result of consumers and other economic agents asking governments to erect trade barriers. The economic model that underpins multilateral trade policy—as manifest in World Trade Organization (WTO) agreements—only predicts that firms will lobby for protection, with no provisions for how governments faced with requests for protection from other groups can respond. Consequently, governments have been forced to defend the imposition of trade barriers using spurious justifications; the WTO dispute mechanism has largely dismissed these justifications, and consumers (and others) feel disenfranchised. The result has been a loss of credibility for the WTO and sometimes its demonization. The WTO needs to change but a new economic model must also be developed to deal with a broader spectrum of protectionist interests. À l'heure actuelle, les questions de commerce international les plus litigieuses ne sont pas alimentées par des producteurs traditionnels qui demandent des mesures protectionnistes, mais plutôt par des consommateurs et d'autres agents économiques qui demandent que les États érigent des barrières commerciales. Le modèle économique à la base de la politique commerciale multilatérale – manifeste dans les accords de l'Organisation mondiale du commerce (OMC) – prévoit seulement que les entreprises exerceront des pressions protectionnistes, sans disposition sur la réaction possible des États qui sont confrontés à des demandes de protectionnisme provenant d'autres groupes. En conséquence, les États ont été forcés de défendre l'imposition de barrières commerciales en utilisant de fausses justifications. Le mécanisme de règlement des différends de l'OMC a en grande partie rejeté ces justifications, et les consommateurs (et autres agents économiques) se sentent privés de leurs droits. L'OMC a ainsi perdu de sa crédibilité et est parfois diabolisée. L'OMC doit être revue, mais il faut également élaborer un nouveau modèle économique pour tenir compte d'un large éventail d'intérêts protectionnistes.  相似文献
