In the context of the Partnership Agreements between the European Union (EU) and the African, Caribbean, and Pacific countries, this study estimates ad valorem tariff equivalents of European food safety standards on imports of key horticultural and fish products from Kenya, Tanzania, Uganda, and Zambia. The study uses an extension of the price‐wedge method to account for imperfect substitution and factor endowment in monopolistic competition. The estimated tariff equivalents are 55% and 98% for imports of fresh peas from Zambia to the Netherlands and the U.K., respectively. They range from 39% to 64% for imports of green beans and avocados from Kenya and from 63% to 270% for imports of frozen fish fillets in EU countries from the East African Community. We also observe large variations in tariff equivalents for the horticultural and fish products over time and EU importing countries. 相似文献

Recent increases in food and other commodity prices have highlighted concerns that many poor countries are net food importers and higher food prices would worsen their trade balances. In this article, we analyze the changes in food trade balances associated with the 32% increase in food prices from 2000/2001 to 2004/2005. We find a small deterioration in food trade balances of low‐income countries and an improvement in middle‐income countries. The deterioration is most severe for countries in conflict and small island states, so attention should be placed first on these countries and on a few very‐low‐income countries that are also vulnerable. Because low‐income countries as a group had much lower agricultural GDP growth rates than middle‐income countries, the answers to food vulnerability in low‐income countries should probably be addressed within the context of incentives for agricultural production. 相似文献

In an imperfectly competitive industry, differentiated products compete with each other with price rather than quantity as the strategic variable. Several previous studies have employed a generalized Nash–Bertrand model: Liang (1989) , Cotterill (1994) , Cotterill et al. (2000) , and Kinoshita et al. (2002) ; however, only Liang has explored the theoretical foundations of that model. This article generalizes the Liang two‐good model to three goods. A surprising and important result follows. Price‐conjectural variations do not exist in models with three or more goods. Price‐reaction functions, however, exist in multiple‐good models. We estimate them jointly with a brand‐level demand system to evaluate the total impact of a brand manager's price change on own quantity. In a differentiated product market, this is a useful addition to a partial demand elasticity approach, because a change in one brand's price typically engenders a price reaction by other brands that affects own quantity via substantial cross‐price elasticities among substitutes. Strategic pricing in the Boston fluid milk market was also influenced by the existence of a raw milk price support program, the Northeast Dairy Compact. We find that the advent of the Compact was a focal point event that crystallized a shift away from Nash–Bertrand to more cooperative pricing. If the downstream market is not competitive, one needs to consider strategic price reactions when designing and evaluating agricultural price programs. 相似文献

This article analyses the relationship between foreign direct investment and the performance of European agribusiness firms. Motivated by the role of heterogeneous firms in new trade theory and using a firm‐level dataset, statistical analyses identify key differences between firms investing in foreign economies and those that do not. A binary choice model quantifies the relationship between firm characteristics and the decision to engage in foreign investment. Size and – less strongly – productivity are greater for multinationals relative to domestic firms. Furthermore, European multinationals are characterised by a larger debt to equity ratio and show lower labour and input costs. 相似文献

This article estimates the pass‐through rates between diesel fuel and retail milk prices at the product brand level. Using a random coefficient logit demand model and taking the direct and indirect impacts of energy prices, this research identifies changes in pass‐through rates before and after the great recession in 2008. Empirical results show that diesel prices significantly impacted the retail prices of milk products and are an important determinant of food price inflation. Pass‐through rates are estimated to range from 0.16 to approximately 0.60 through 2008 with an average of 0.22 for the whole period. Statistical tests indicate that pass‐through rates before June 2008 were significantly higher than after June 2008 when they dropped significantly to 0.04 to 0.17. Interestingly, private label brands have the lowest pass‐through rates, implying that compared to manufacturer brands, private label prices are more insulated from diesel price shocks. 相似文献

Food quality has become an important determinant of success in global food trade and growers for international markets have to continuously adjust to buyers’ requirements. It is, however, not clear to what extent there is a demand for food quality—and how much buyers are willing to pay for it—in domestic food markets of developing economies. Based on unique comparable price and trader data in a poor country in Africa (Madagascar) and an emerging economy in Asia (India), we compare food quality and quality's pricing. We find significantly better quality and higher quality premiums (using revealed as well as stated preference methods) in India than in Madagascar. These findings are consistent with a simple theoretical model, solely based on average income gaps between the two countries. 相似文献

Historically, earnings from farming in many developing countries have been depressed by a pro‐urban bias in own‐country policies, as well as by governments of richer countries favoring their farmers with import barriers and subsidies. Both sets of policies reduced global economic welfare and agricultural trade, and added to global inequality and poverty. Over the past three decades, much progress has been made in reducing agricultural protection in high‐income countries and agricultural disincentives in developing countries. However, plenty of price distortions remain. As well, the propensity of governments to insulate their domestic food market from fluctuations in international prices has not waned. Such insulation contributes to the amplification of international food price fluctuations, yet it does little to advance national food security when food‐importing and food‐exporting countries equally engage in insulating behavior. Thus there is still much scope to improve global economic welfare via multilateral agreement not only to remove remaining trade distortions but also to desist from varying trade barriers when international food prices gyrate. This article summarizes indicators of trends and fluctuations in farm trade barriers before examining unilateral or multilateral trade arrangements, together with complementary domestic measures, that could lead to better global food security outcomes. 相似文献

This paper surveys the linkages between malaria and agriculture, focusing on the economic impacts of the disease. We adopt Negin's (2005) conceptual framework to examine the potential impacts of malaria in the agricultural sector, including both direct and indirect impacts. In addition to health care costs, malaria causes loss of agricultural labor and slows adoption of improved practices in agriculture. Furthermore, some agricultural practices and development interventions are known to facilitate the spread of malaria, exacerbating its impacts. Given the importance of both agriculture and malaria in developing countries, especially in Africa, the interaction between them could be a significant factor in economic growth. The review identifies gaps in past research on this topic. A better understanding of malaria's impact on agricultural productivity, coupled with efforts to strengthen capacity to deal with malaria, would enhance policies and programs aimed at combating malaria and curbing its impacts on agricultural productivity. 相似文献

Food deserts and their potential effects on diet and nutrition have received much attention from policymakers. While some research has found a correlation between food deserts and consumer outcomes, it is unclear whether food deserts truly affect consumer choices. In this article, we compare food prices in food deserts, defined as low‐income, low‐access census tracts, and nonfood deserts to observe whether and to what extent consumers face higher prices for a complete diet in food deserts. If a nutritionally complete diet costs significantly more in food deserts, resident consumers may be constrained from consuming healthier foods. We use store‐level scanner data from a nationally representative sample and calculate a census‐tract level Exact Price Index (EPI) based on a food basket defined by the Thrifty Food Plan (TFP). The EPI addresses potential biases from both product heterogeneity and variety availability. We find that the overall price impact of living in a food desert is small; low‐access areas have only 3.5% higher EPI than high‐access counterparts. However, consumers who are constrained to shop within their own census tracts face a much higher EPI than high‐access counterparts (9.2%). The higher EPI primarily comes from lower variety availability in food deserts. 相似文献

This study examines the national effect of U.S. direct payments on the extent and direction of biased technical change on U.S. agriculture. We also assess the economic significance of the estimated bias effects for economic policy modeling endeavors involving a reduction of domestic support payments. A two outputs (livestock and crops) and four inputs (labor, capital, land, and material) translog cost function was estimated from national time series (1948–2011) data. Results indicate that payments do not induce output‐biased technical change. We do find evidence of Hicksian bias that is land using and material input saving attributable to support payments. Global computable general equilibrium simulations suggest that price and output effects of discontinuing direct payments are 1/4 to 1/3 the size once the bias effects are incorporated. 相似文献

Using an original dataset from the Vietnamese catfish sector, I analyze the impact of vertical coordination options, namely, contract farming and vertical integration, on farm performance, which is measured in terms of yields and revenue per hectare. The effects of vertical coordination are estimated using a maximum simulated likelihood estimator and a two‐stage least square regression with instrumental variables to account for endogenous farm and household characteristics and selection on unobservable characteristics. The results show that vertically integrated farms have substantially higher yields and revenue per hectare than nonintegrated farms. The levels of gains that can be attributed to integration are large and consistent under different estimation procedures, and there is no difference between nonintegrated and contract farms in terms of farm performance. 相似文献

Although a great deal of research exists on gender and agriculture, few studies investigate the implications of reduced gender disparities in households for technical efficiency. In this article, I compare the levels of technical efficiency achieved on plots operated by households with different levels of gender disparities. Using plot‐level data from the 2011–2012 Bangladesh Integrated Household Survey and drawing on indicators derived from the Women's Empowerment in Agriculture Index, I estimate a stochastic frontier production function model, which includes women's empowerment in agriculture as an exogenous determinant of technical inefficiency. I find that reduced gender disparities within households (measured in terms of the empowerment gap between spouses) are associated with higher levels of technical efficiency. This result extends to plots that women jointly manage with their spouses, as well as those that women do not actively manage. 相似文献

This paper determines the impact of food industry market power on farmers' incentives to promote in a situation where funds for promotion are raised through a per‐unit assessment on farm output and food industry technology is characterized by variable proportions. Specifically, building on earlier studies by Azzam [Am. J. Agric. Econ. 80 (1998) 76] and Holloway [Am. J. Agric. Econ. 73 (1991) 979], Muth's [Oxford Econ. Papers 16 (1965) 221] model is extended to consider the farm‐level impacts of generic advertising when downstream firms possess oligopoly and/or oligopsony power and advertising expenditure is endogenous at the market level. Applying the model to the US beef industry, we find that for plausible parameter values market power reduces farmers' incentives to promote. However, the disincentive is moderated by factor substitution, and effectively vanishes as the factor substitution elasticity approaches the retail demand elasticity. This suggests that the Dorfman–Steiner theorem, suitably modified to account for factor substitution, suffices to indicate optimal advertising intensity in the US beef sector. 相似文献

We examine the effects of external and internal expenditure on research and development on the business performance of industrial agri‐food enterprises. For this purpose, a data sample from the Encuesta de Estrategias Empresariales en España (Survey of Business Strategies in Spain) was used, which includes information on more than 400 businesses over the period 2000–2008. The econometric analysis uses quantile regressions to address the vast asymmetry of the variables and to identify non‐linear relationships. The results reveal interesting new findings on the impacts of R&D on the agri‐food industry. The most evident, although not the most immediately apparent, relationship concerns the positive effects of external R&D on business performance. Internal R&D was also revealed to be an important way of enhancing the productivity of SMEs. In addition, the modernisation of the production process through investment in capital goods continues to be the main path to improve competitiveness. However, support was found neither for the inverse relationship, that is the most profitable firms are those that spend the most on R&D, nor for complementarity between external and internal R&D. The latter would imply that the bulk of Spanish agri‐food firms have at most the capacity for only one type of R&D. 相似文献

This article reviews the concept of the “market” and questions the standard view of the “market” developed by orthodox economic theory. The article highlights how Economic Sociology and Convention Theory is more useful in understanding markets and appreciating markets as social constructs, which are governed by institutions and social orders. This adjustment in the analytical framework to study markets and especially food markets, is useful in unpacking the various dimensions of “quality” in food products and illustrating that “quality” is an institution that is shaped by society and by culture. 相似文献

Standards have played an important role in food trade for a very long time. Their rapid growth in recent years has triggered vigorous debates on their impacts on international trade and development, with many arguing that standards are “non‐tariff barriers” to trade and that standards are marginalizing the poor. I present conceptual frameworks and review empirical evidence on the equity and efficiency effects and the political economy of standards. Models which incorporate essential aspects of standards yield complex theoretical results and nuanced conclusions. Careful empirical analyses support such nuanced arguments and find complex effects. For trade, standards can create welfare gains but also involve rent redistribution which induces lobbying by interest groups to set the standards at their preferred level. This makes it difficult to distinguish socially desirable standards from those resulting from political rent‐seeking. For development, it is crucial to explicitly account for (a) the endogeneity of the institutional organization of value chains and (b) both smallholder contracting and employment creation on large scale farms when considering the impact of standards on development and poverty. 相似文献

This article presents a political economy model of public standards in an open economy. We use the model to derive the political optimum and to analyse different factors that have an influence on this political equilibrium. We analyse the relationship between trade and the political equilibria and compare the political outcome with the social optimum to identify under which cases political considerations lead to standards being set ‘too low’ or ‘too high’, and which standards could be labelled as protectionist measures. 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
