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

To understand the market for sustainable foods, it is important to allow for heterogeneous preferences. However, most studies of consumer preferences for sustainable foods only investigate average consumer preferences. They do not take into account that some consumer segments attempt to purchase as much sustainable food as possible, others are almost indifferent to the notion of sustainable food, and still others consider sustainable food a complete hoax. The aim of this study is to explore the preferences for various types of premium eggs across three consumer segments. We conduct a choice experiment including 900 Norwegian consumers and perform a behavioural segmentation based on the frequency of organic food purchase. We find that the segment purchasing the most organic food is, as expected, willing to pay a significant premium for organic eggs over eggs displaying only enhanced animal welfare. However, most consumers, who only occasionally purchase organic products, are unwilling to pay more for organic eggs than for enhanced animal welfare eggs, suggesting diminishing marginal utility for additional attributes. We find that a third consumer segment attempts to avoid organic eggs, even when they cost the same as other eggs. Our findings suggest that organic products will be unsuccessful in acquiring a larger share of the market as long as most consumers are unwilling to pay a premium for organic products with all their cost increasing sustainable attributes over products that have only a single sustainable attribute, in our case enhanced animal welfare.  相似文献

We seek to design and implement a WTP elicitation instrument closely resembling an actual grocery shopping experience. An incentive-compatible choice experiment is used to elicit values for a non-GM attribute and a country-of-origin attribute of Canola oil. The choice context is varied to assess whether revealed-preference choice experiments are affected by choice variety. A median premium for non-GM Canola oil is found to approximate C$0.45 or C$0.62/liter according to the choice variety context; different country-of-origin effects are also found as choice context varies. Hypotheses as to why these significant effects of choice contexts occur are suggested.
Nous cherchons à concevoir et à mettre en application un instrument de révélation de la VDP qui ressemble étroitement aux choix que fait un consommateur lorsqu'il effectue son marché. Nous avons utilisé une méthode expérimentale compatible avec les incitations des participants afin de découvrir la valeur accordée à deux caractéristiques de l'huile de canola: non génétiquement modifiée et étiquetée selon le pays d'origine. La liste des choix est variée afin d'évaluer si les préférences révélées sont influencées par la gamme de choix. La prime médiane de l'huile de canola non génétiquement modifiée est d'environ 0,45 $CAN ou 0,62 $CAN le litre selon les choix proposés. Différents pays d'origine figurent aussi dans cette liste de choix. Nous avons formulé des hypothèses quant aux raisons pour lesquelles la gamme de choix a des effets importants.  相似文献

This article argues that the politics of scale in a nested hierarchy of cotton governance institutions in Burkina Faso are weighted against smaller producers, with what looks like success from a broader scale producing uneven development at the local scale. We show that at the national level, Burkina Faso has succeeded in increasing its output of cotton lint. At the local level, we see a differentiated outcome where the liberalization‐initiated system of shared liability has improved overall cotton cooperative management but this has come at a significant cost: the exit of poorer farmers from the cotton sector and an increasing debt burden on those individual farmers who remain. The novelty of this article is that it considers producers' institutions as a key level of analysis linking macro‐scale policy decisions to micro‐scale village and farm outcomes. The resulting analysis allows us to focus on the politics of scale, particularly the power relations of different actors and the ability to capture resources at different levels, as well as the role of multilevel institutions in producing differentiated outcomes.  相似文献

We analyse European agri‐food firms’ choices about innovation in‐house or through outsourcing and provide empirical evidence about the correlation between these strategies. The relationship between the innovation strategy and firm‐, industry‐ and innovation‐specific characteristics is analysed through a bivariate probit model, which uses firm data from the EFIGE Bruegel‐UniCredit dataset. Transaction cost, resource base and knowledge governance arguments are used to explain the choice of innovation strategy. Our results show that the decisions to innovate in‐house or through outsourcing are independent from each other. In addition, we find that several organisational characteristics such as communication systems, human resource practices and specialisation are likely to influence both strategies. Conversely, organisational characteristics such as the allocation of authority and the business network do not seem relevant in determining the innovation strategies of the European agri‐food sector.  相似文献

Consumers are apprehensive about transgenic technologies, so cisgenics, which limit gene transfers to sexually compatible organisms, have been suggested to address consumer concerns. We study consumer preferences for rye bread alternatives based on transgenic or cisgenic rye, grown conventionally or without the use of pesticides, relative to traditionally bred rye, grown with conventional or organic farming methods. Stated preference (SP) data from a choice experiment are combined with revealed preference (RP) data from market purchases from the same respondents. Results show that respondents prefer pesticide‐free production methods, and that while cisgenics is preferred over transgenics, the majority of respondents favour traditional breeding methods. The distribution in preferences suggests that some respondents prefer bread from cisgenic crops produced without pesticides over traditional crops produced using pesticides. Preferences for organic bread are stronger than for pesticide‐free products. From a policy perspective results suggest that excluding cisgenics from mandatory labeling in the EU, or including it in the voluntary non‐GM labelling in the US, would cause welfare losses for consumers.  相似文献

Many governments in developing countries distribute fertilizer at subsidized prices in an effort to stimulate small farmers' agricultural productivity and food security. Prior fertilizer demand studies have largely failed to account for the effects of government programs on farmers' commercial purchases. Using a double hurdle model and nationally representative rural household panel data in Zambia, we distinguish between these sources and measure the contemporaneous "crowding in" and "crowding out" effects of government input programs on commercial fertilizer sales. Where the private sector is relatively active and average wealth is higher (areas seemingly more likely to be targeted by government programs), results indicate that subsidies have substantially crowded out the private sector, in some cases to the point that such programs could actually lower overall fertilizer use. On the other hand, in poorer areas where the private sector is relatively inactive, subsidies help to generate demand and crowd in private sector retailers. Empirical studies explicitly modeling farmers' fertilizer purchase behavior within a dual marketing framework can provide important insights for agricultural policy discussions in developing countries.  相似文献

Different economic valuation methodologies can be used to value the non‐market benefits of an agri‐environmental scheme. In particular, the non‐market value can be examined by assessing the public’s willingness to pay for the policy outputs as a whole or by modelling the preferences of society for the component attributes of the rural landscape that result from the implementation of the policy. In this article we examine whether the welfare values estimated for an agri‐environmental policy are significantly different between an holistic valuation methodology (using contingent valuation) and an attribute‐based valuation methodology (choice experiment). It is argued that the valuation methodology chosen should be based on whether or not the overall objective is the valuation of the agri‐environment policy package in its entirety or the valuation of each of the policy’s distinct environmental outputs.  相似文献

Payments for environmental services (PES) have gained wide popularity as approaches to promote environmentally friendly land use or agricultural production practices. Yet academics have also voiced concerns against seeing PES as a panacea. This article discusses whether PES is an appropriate and promising approach to promote so‐called “climate‐smart agriculture” (CSA) practices, which we define as agricultural production practices that contribute to CO2 emission reductions and/or removals and provide benefits to farmers via increased productivity and profits and reduced vulnerability to climate change. PES appears most promising for the promotion of CSA practices in small‐scale farming contexts with low incomes. Effective design, however, requires solid estimates of cost and benefit flows from CSA adoption over time, accounting for differences in socioeconomic and ecological conditions, and addressing the risk of leakage. Funding for such PES will likely have to come from public sources, and seems most promising where synergies with other objectives such as agricultural development, food security, and climate adaptation or other environmental services exist. The potential of alternative approaches for CSA support such as taxation with rebates for CSA practices, CSA‐related investment support such as microcredits, and hybrid approaches such as conditional microcredit should be further investigated.  相似文献

We estimate the efficiency and equity returns to farmland rental markets in Malawi using a matched tenant–landlord survey of smallholder farm households in four districts. Our sample allows us to more fully observe the landlord side of the rental market, which is almost always missing in previous studies. Our results suggest that land rental markets promote efficiency by facilitating a net transfer of land to more productive farmers. We also find that land rental markets promote equity as conventionally defined in the land markets literature, that is, by transferring land from land‐rich households to land‐poor households, and from labor‐poor to labor‐rich households. However, our study identifies some important challenges for land rental markets in this context. First, we find that tenants in our sample are wealthier than their landlord counterpart on average in all dimensions other than landholding. In addition, most landlords report the motive for renting out their land as either the need for immediate cash, or the lack of labor and/or capital to cultivate the plot that was rented out. These findings align with concerns about potential “stress renting” by poor landlords and suggest the value of defining equity along a broader set of dimensions other than simply equalizing the distribution of farmland and labor.  相似文献

This study presents evidence of profound farm‐level transformation in parts of sub‐Saharan Africa, identifies major sources of dynamism in the sector, and proposes an updated typology of farms that reflects the evolving nature of African agriculture. Repeat waves of national survey data are used to examine changes in crop production and marketed output by farm size. Between the first and most recent surveys (generally covering 6 to 10 years), the share of national marketed crop output value accounted for by medium‐scale farms rose in Zambia from 23% to 42%, in Tanzania from 17% to 36%, and in Nigeria from 7% to 18%. The share of land under medium‐scale farms is not rising in densely populated countries such as Kenya, Uganda, and Rwanda, where land scarcity is impeding the pace of medium‐scale farm acquisitions. Medium‐scale farmers are a diverse group, reflecting distinct entry pathways into agriculture, encouraged by the rapid development of land rental, purchase, and long‐term lease markets. The rise of medium‐scale farms is affecting the region in diverse ways that are difficult to generalize. Findings indicate that these farms can be a dynamic driver of agricultural transformation but this does not reduce the importance of maintaining a clear commitment to supporting smallholder farms. Strengthening land tenure security of local rural people to maintain land rights and support productivity investments by smallholder households remains crucial.  相似文献

Following a period of poor performance in the 1990s, India's agricultural growth rate has reaccelerated in the 2000s. Some believe the reacceleration has been a product of intensified investment, which in turn has spurred yield growth. Others suggest it is because India's newly wealthy citizens have demanded greater product diversification. To examine these hypotheses, we use growth accounting techniques in conjunction with more complete agricultural production data than in past studies to construct state, regional, and national output, input, and total factor productivity quantity indexes, which can be decomposed into their underlying sources. Sectoral performance evaluation suggests that, since 1980, output growth has diffused away from the northern “grain belt” and toward high‐value agriculture in traditionally less‐productive regions. Productivity growth, rather than resource use, has accounted for these geographical and intensity shifts. The growth burst has not, as the literature has primarily argued, been uniquely explainable by yield growth or product diversification but by a variety of factors, including area expansion. For example, the contributions of irrigation technologies permitting double‐cropping have until now been largely ignored.  相似文献

European consumers and, in particular, German consumers are known to be very critical toward the introduction of genetically modified (GM) foods. It is analyzed here whether German consumers do reject second-generation GM foods, too. Whereas first-generation GM crops induced producer-related benefits, second-generation GM crops are associated with consumer-oriented benefits like an improvement of nutritional quality. The determinants of demand for second-generation GM rapeseed oil are investigated within an online survey of 1,556 German consumers. It is elaborated how two functional properties of the product matter; that is, long-chain omega-3 fatty acids and the cholesterol-lowering effect of phytosterols. It turns out that GM rapeseed oil is neglected by 74% of all respondents. Output traits, however, will increase the probability of purchases of GM rapeseed oil. This is more the case for long-chain omega-3 fatty acids than for phytosterols.  相似文献
