Consumer welfare effects from policy changes are traditionally calculated using estimates of consumer preferences for the underlying goods and services affected. This conventional approach is indirect, does not consider preferences people may have for the policies themselves, and makes it difficult to easily compare relative preferability of a large set of policy options. In this paper, we use the best–worst scaling approach to determine consumers’ preferences for 13 policies. A nationwide survey of 1,056 U.S. consumers indicates the highest levels of support for investments in agricultural research and requirements of food and agricultural literacy standards in public education. Fat, calorie, and soda taxes are the least popular; fewer than one-third of respondents are in favor of these three policies.  相似文献

We analyze growth and diversification of U.S. dairy farms by examining changes in ten size cohorts and new entrants through three successive censuses. We reject Gibrat's law and the mean reversion hypothesis of growth. Growth rates appear bimodal where the smallest and largest farm cohorts grow fastest. All cohorts diversify but the largest farms do not diversify as rapidly as medium-sized farms. New entrants are generally large, and they diversify more rapidly than comparably sized incumbents do. These data suggest that scale economies persist even for the largest cohort of U.S. dairy farms and scale economies dominate scope economies for large farms.  相似文献

Infrastructure, agglomeration, product and input markets, fiscal attributes, and labor markets of local communities influenced food manufacturing location decisions in the lower 48 United States, 2000–2004. Negative binomial regression and spatial clustering methods forecast food processor location patterns at the county level. Noncore counties are at a comparative disadvantage with respect to attracting most food processors, but nonmetropolitan counties adjacent to urban areas may be attractive investment sites for footloose, supply, and demand-oriented food manufacturers.  相似文献

New Communities are again being promoted as an alternative to sprawling urban growth. This paper uses the results of a unique survey of the real estate development communities in the U.S. and U.K. to examine the likelihood that future New Communities will provide the array of amenities necessary to create developments that provide a true alternative to sprawl. Based on an analysis of this data we conclude that while developers do envision New Communities as more amenity rich than much of the suburban master-planned communities of the last few decades, they are nonetheless still likely to produce developments that have an insufficient array of amenities to make future New Communities a strong alternative to sprawl.  相似文献

Traceability systems that track both physical entities and their less tangible attributes are increasingly widely used in contemporary food supply to meet a range of regulatory and commercial objectives, including a growing number of ethical concerns. Even with a traditional combinable and blended food crop such as wheat to bread there is clear evidence of traceability from the variety and crop in the field through to the mill to the bakery to the shelf. This study examines the traceability systems that have emerged in the wheat to bread supply in the UK, and the ethical concerns that have emerged within this supply process. The study reveals that these ethical concerns are dynamic and evolving and are contested. In the case of the supply chains studied, a priority concern with safety aspects has been followed by an emerging greater focus upon the provenance of the wheat and flour and upon the environmental impacts of the more industrialized supply chains. A study of the traceability schemes in the chains and the views of the stakeholders reflects quite restricted ‘fields of ethical vision’. The governance and the transmission of information along the chains to the final consumer are quite restricted and partial, inhibiting transparency. The realization of greater transparency and ethical traceability to address different moral perspectives will need further changes in the governance and operation of the supply chains.  相似文献

Green Revolution technologies transformed Bangladesh’s agricultural system through the introduction of high-yielding rice and wheat varieties, chemical fertilizers and pesticides, and the expansion of tubewell-irrigated area, enabling crop production during the dry season. However, serious challenges continue to plague the agriculture sector, including scarcity of land due to high population density, unbalanced use of fertilizers and pesticides, and great variation in water supply across seasons – from drought to stagnant flood conditions. Further expansion of irrigated area – including through the continued development and improvement of surface water systems – is being eyed by Bangladesh’s Ministry of Agriculture to address many of the remaining challenges facing the country. However, such expansion is not without risks or consequences, and a careful analysis of who benefits from irrigation, and how, must guide development priorities.We examine plot-level data for rice production during Bangladesh’s three rice seasons – aus, boro, and aman – across a nationally-representative household survey in Bangladesh. While rainfall is the most important determinant of rice yield during aus and chemical inputs are most important during aman, access to irrigation has the greatest influence on boro rice yield during the dry season, particularly for the coastal south. The government of Bangladesh is planning massive investments in the southern region for the improved provision of surface water irrigation. The expected decline in groundwater, coupled with our econometric findings, suggests that expanding boro production in the south may not be a good strategy to promote, for the region. Whether brackish shrimp aquaculture can provide an equitable and sustainable livelihood alternative should continue to be a focus of research.  相似文献

This viewpoint paper presents a reaction to the article by Brandt et al. (2016). It highlights the complexities inherent to the attribution of deforestation impacts to policy interventions when using remote-sensing data. This critique argues that in the context of the Congo a suite of factors (i.e., population density in particular) other than those considered by Brandt et al. (e.g., type of forest, distance from roads and markets) play essential roles in determining the fates of forests. It also contends that care is needed when making decisions regarding which units will be included in the comparison group so that contextual factors and on-the-ground information are properly considered (e.g., when logging operations are inactive or when a concession is used for ‘conservation’ purposes). Finally, it proposes that a focus on an analysis of deforestation rates for a given level of timber production might be a metric that more accurately represents one aspect of the consequences of forest management, which should also consider the appraisal of trade-offs associated with a larger set of social, financial and ecological objectives.  相似文献

Urban agriculture (UA) is rapidly growing in popularity and significance across the Western hemisphere. For over two decades North Americans have embraced the concept, although in Europe the idea of UA has only recently gained attention from academics, practitioners and policy makers. Networks are beginning to form in the UK, sometimes bound by a ‘food charter’: a statement of aims which bring together businesses, practitioners and other bodies involved or interested in sustainable food systems. More recently, food charters have become popular tools for pursuing the UA agenda. In this paper we provide a view on this method of moving forward the local food agenda; primarily using a case study of Birmingham, we comment on its success and potential for the future.  相似文献

The challenge for agricultural production in the 21st century is to produce sufficient high-quality food whilst minimizing impact. Life cycle assessment (LCA) can help by identifying the parts of a supply chain with the greatest environmental impact, and to determine which technologies – for example plant breeding – may be most appropriately employed to minimize negative impacts. A ‘plough-to-plate’ LCA of a porridge oat production chain was undertaken using data that corresponds to the inputs and outputs of an indicative supply chain. The greatest environmental impact of the porridge oats life cycle occurs in crop production and cooking. There are traits for oats that are available for manipulation by plant breeders, which can influence these areas; these include yield, nitrogen use efficiency and beta-glucan content. Therefore plant breeding may be a useful strategy for improving the sustainability of the crop. However LCA cannot be a definitive tool to guide plant breeding and therefore this approach needs to compliment others. Nevertheless this study highlights that porridge oat supply chain sustainability would benefit from an integrated effort stretching from the geneticist to consumer; a finding that is likely to be relevant to other food supply chains.  相似文献

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

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

ABSTRACT

This report investigates whether deregulation of the Australian wheat export market induced a structural change in the price data generation process. We analyze the unit root properties of Western Australian wheat price series by testing for the possibility of single and double structural breaks. Daily spot prices for the period of May 20, 2003, to September 14, 2010 are used. We find the wheat price series has a unit root with two structural breaks but neither breaks coincides with the time when the Wheat Export Marketing Act 2008 came into effect on July 1, 2008. The implication of our results is that deregulation was not the main cause of structural breaks in the price series in the sample period.  相似文献

Western Australia experienced a prolonged resources boom for more than a decade commencing in 2001. The majority of mining industry employees commute long distances from their homes, living onsite in company accommodation and working compressed rosters for a prescribed period before commuting home again for furlough and recommencing the work and commute cycle. Many community leaders, politicians and businesses complain that company policies and industrial relations arrangements, which enabled long distance commuting (LDC), undermine regional economic development. They argue that the host communities closest to mining operations bear the brunt of globally driven boom and bust markets and experience many of the disadvantages but few of the opportunities associated with booms or busts, while source communities, particularly large cities, reap the benefits from repatriated salaries, increased populations and investment derived from mining activities in the host communities.This paper examines the role of long distance commuting as a tool for mitigating the impacts of the boom and bust cycles in the resources industries of Western Australia, focusing on the resources-rich region of the Pilbara. The paper will also speculate the social and economic impact on the mining communities and the state more broadly if government had capitulated and restricted long distance commuting.  相似文献

Unexceptionally all metropolitan areas throughout the world are surrounded by peri-urban areas that are neither urban nor rural in the conventional sense. Peri-urban areas are transition spaces, where the changes in different land uses are incessantly occurring. Determining the boundaries of these areas are critical to develop appropriate policies to manage and preserve them. The perpetual transition in peri-urban landscapes makes the boundary demarcation of these areas highly difficult. This paper aims to answer the question of what the most suitable methodological approach to demarcate peri-urban areas is. In order to address this question, the study undertakes a systematic review of the relevant literature. The findings show that a generic method does not exist to demarcate peri-urban areas as characteristics of peri-urban areas are not uniform across the globe. This paper advocates that techniques for peri-urban demarcation should be geographically specific, and in every case the regional and local contexts–e.g., political system, institutional arrangement, societal characteristic, environmental qualities, and economic drivers that underpin the peri-urban development—should be considered. The study provides insights to policymakers in order to determine peri-urban boundaries by tailoring available peri-urban demarcation techniques to their regional and local contexts.  相似文献

Weak institutional development and information flows have constrained the extent to which the smallholder farming sector in developing countries can significantly drive growth and poverty reduction. This is despite widely implemented economic liberalisation policies focussing on market efficiency. Farmer organisations are viewed as a potential means of addressing public and private institutional failure but this has frequently been limited by inequalities in access to power and information. This article investigates two issues that have received little research attention to date: what role downward accountability plays in enabling farmer organisations to improve services and markets, and what influences the extent to which downward accountability is achieved. Kenya Tea Development Agency (KTDA), one of the largest farmer organisations in the world (>400,000 farmers) is examined alongside wider literature. Mixed methods were used including key informant interviews, and eight months of participant observation followed by a questionnaire survey. The article concludes that without effective downward accountability farmer organisations can become characterised by institutions and mechanisms that favour elites, restricted weak coordination and regulation, and manipulated information flows. This in turn reduces individuals’ incentives to invest. If farmer organisations are to realise their potential as a means of enabling the smallholder sector to significantly contribute to economic growth and poverty reduction, policy and research needs to address key factors which influence accountability including: how to ensure initial processes in formation of farmer organisations establish appropriate structures and rules; strong state regulation to enhance corporate accountability; transparent information provision regarding actions of farmer organisation leaders; and the role independent non-government organisations can play. Consequently attention needs to focus on developing means of legitimising rights, building poor people's capacity to challenge exclusion, and moving from rights to obligations regarding information provision.  相似文献

Contingent tariffs for agri‐food commodities have been proposed as a Special Safeguard Mechanism (SSM) in the Doha Round negotiations by the G33 group of countries as an instrument to control downward spikes in their border prices and/or surges of imports. The objective is to safeguard the livelihood security of farm households in poor countries. To date, most analysis of such tariffs uses stochastic partial equilibrium models with perfect competition. Yet in many markets for such commodities, imperfectly competitive market intermediaries play an important role in determining producers' prices, as do state trading enterprises (STEs). A stochastic partial equilibrium model of a typical importing country situation is specified in which there are either imperfectly competitive domestic intermediaries with a contingent tariff or an STE. The role of these intermediaries in influencing price behaviour and livelihood security in the presence of contingent tariffs alters the conclusion based on models of perfect competition. Using Monte‐Carlo simulation, it is shown that the efficacy of a contingent tariff is substantially reduced as the number of firms declines because increasingly they absorb the tariff, and the procurement price and producer surplus do not increase to the extent that they do under perfect competition.  相似文献

The persistence of agricultural protectionism throughout the world is intriguing given the widely recognized benefits of free trade. The political economy literature over the last decades has considered groups’ interest, politicians’ preferences, and their interactions within domestic politics as the primary forces driving agricultural protection. Yet, a growing body of studies suggests that it would be judicious to weigh in consumers’ or taxpayers’ perspectives in deciphering the nature of agricultural protection. This study examines U.S. citizens’ preferences about government intervention in agriculture and trade. Results show that they are in strong support of agricultural protection and their perceptions of national food security, family farms, environmental sustainability, and multifunctionality of agriculture play a significant role in shaping their support/opposition toward government intervention. The conventional political economy literature theorizes that consumers or taxpayers would oppose public policies that increase their tax burden; however, in the case of the farm sector, they have little incentive to voice their objections given the costs of farm programs are spread across a large number of consumers and taxpayers. U.S. citizens’ support for government involvement in agriculture as reported in this and other prior studies does not lend support for such political economy explanation.  相似文献

This article examines the dynamic effects of changes in bilateral exchange rates on changes in bilateral trade of bulk, intermediate, and consumer‐oriented agricultural products between the United States and its 10 major trading partners. We find that, for consumer‐oriented products, U.S. exports are highly sensitive to bilateral exchange rates in both the short and long run, while U.S. imports are mostly responsive only in the short run. For bulk products, on the other hand, U.S. exports and imports are relatively insensitive to exchange rate changes in both the short and long run. For intermediate products, exports and imports are responsive to exchange rate changes in the short run, but not in the long run. It is also found that income of the United States and its trading partners has a significant effect on U.S. exports and imports of the three types of agricultural products in both the short and long run.  相似文献

The Australian Mushroom Growers Association (AMGA) has recently developed a revised marketing strategy to promote mushrooms using messages based on scientific findings about the nutrition and health consequences of regularly incorporating mushrooms into meals. This article evaluates impacts based on a test‐market experiment in Tasmania. We use a difference‐in‐differences econometric methodology to quantify the programme‐induced shifts in demand, and we use the resulting estimates in a supply and demand modelling framework to quantify the effects of promotion‐induced demand shifts on prices, quantities, and measures of economic well‐being. We estimate a conservative benefit–cost ratio for Tasmanian producers of 7.6:1 if they were to bear the entire cost and 11.4:1 if the programme were financed by a levy on production (or spawn). The aggregate benefit–cost ratio, including benefits to consumers is also 11.4:1.  相似文献

The aim of this paper is to consider the sources of finance used to support major capital expenditure in the UK Higher Education sector and to reflect on any differences between traditional corporate finance theory and practice in the UK university sector. Utilising both HESA data returns and published annual accounts, an in-depth analysis using a logit structure is carried out on data from the top 63 UK universities over the period 2014–2017, to establish the range of funding sources adopted for major capital projects, all set within the context of the UK macro environment and a period of low interest rates. The research also carries out a survey of funders to understand the decision criteria used by lenders active in the Higher Education sector and a survey of university finance directors to determine the use of the funds, the reasons behind past lending decisions and to ascertain likely future demand for finance to fund major capital projects.  相似文献
