A Belief-Preference Model of Choice for Experience and Credence Goods

We develop a methodology addressing the issue of confounded beliefs and preferences in models of discrete choice. First, we formalise the theoretical framework and logical underpinnings of a belief-preference model of choice for experience and credence goods, where subjective beliefs relate to uncertain product quality. We then present the experimental procedure within the context of an online choice experiment studying consumer food preferences. The empirical strategy leverages information from a quality sorting task to identify and estimate beliefs, while choice data are used to recover preferences. By conditioning product choices on predicted quality perceptions, the issue of endogenous beliefs is resolved.     

退耕还林可持续发展必须解决的一个粮食观问题

西部干旱半干旱农牧交错区退耕还林的基本前提是粮食供给,粮食供给的根本问题是粮食的可持续来源,粮食来源的基本途径从现在起的一段时期内,取决于国家退耕还林还草政策执行年限,现行的“二五八”期限显然太短,不利于该地区已有生态成果的可持续,若不在思想深处变革退耕还林中的粮食观,退耕还林还草工程就不可持续,特别是在粮食价格上涨期,矛盾尤为突出。粮食不仅仅是消费品,对于干旱半干旱农牧交错带生态修复而言,粮食既是生态公共品投入,又是宏观效益显著的政府投资。必须以全球的视野,立足于既要让山绿起来,又要让民富起来的可持续发展要求,从战略高度上树立正确的生态重建粮食观,为中国林草业开拓广阔的发展空间,实现生态效益、经济效益、社会效益并进的科学发展,从农、林、牧结合的全局上做文章,彻底摆脱农业生产资料不足对“三农”的严重困扰。     

Factors Impacting Food Safety Risk Perceptions

We developed and applied a model of consumer risk perceptions of beef food safety to better understand the underlying drivers of consumer demand for food safety. We show how consumer demographics, country‐of‐residence, as well as reliance on, and trust in, alternative food safety information sources affect risk perceptions of consumers in Canada, Japan and the United States. Consumers in all three countries have risk perceptions shaped by their level of reliance on observable and credence attribute information. Risk perceptions of consumers in each country are significantly higher for those less trusting of doctors. Moreover, personal and indirect food safety experiences substantially affect risk perceptions. These results are useful to decision‐makers in developing more efficient supply chain management strategies and public policies aimed at building or sustaining consumer confidence in food safety.     

What agricultural and food policies do U.S. consumers prefer? A best–worst scaling approach

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.     

From Circle of Poison to Circle of Virtue: Pesticides,Export Standards and Kenya’s Green Bean Farmers

In response to growing consumer concerns, developed‐country governments have reduced permissible pesticide residue levels in food. Many food retailers have developed even more stringent private food safety protocols relating to pesticide use, storage and disposal and passed them on to their suppliers. Exporters in developing countries enforce these developed‐country pesticide standards (DC‐PS) by subjecting farmers to close monitoring. This study explores the effects of enforcing compliance with DC‐PS on smallholder farmers’ pesticide‐related health costs. Results suggest that enforcing DC‐PS encourages farmers to use protection that lowers pesticide‐induced morbidity, hence reducing farmers’ health costs from pesticide exposure. The study concludes that there are health benefits to family farmers from complying with DC‐PS beyond the acknowledged income generation from selling fresh produce in premium export markets.     

The consequences of a human food pathogen vaccine on food demand: a calibrated partial‐equilibrium analysis of the U.S. beef market

Human vaccines against several common foodborne pathogens are being developed and could substantially alter consumer and producer behaviour in the markets for foods commonly afflicted by these pathogens. To understand the possible impacts of such an innovation, we derive and calibrate a partial‐equilibrium model using parameters for consumer vaccine uptake from stated‐preference work under an array of assumptions concerning industry moral hazard, consumer awareness and alternative preventive effort exercised by consumers. We simulate three scenarios in the U.S. beef sector: the introduction of a vaccine, the tightening of pathogen standards for beef production and the simultaneous introduction of both vaccinations and tighter standards. Our simulation shows that all policies can increase aggregate surplus given most calibrations; though, the largest effects are attributed to vaccine introductions, which reduce expected damages from foodborne illness among vaccinated consumers without shifting firm costs. However, unaware consumers and aware consumers who choose not to vaccinate experience no change in expected damages when a vaccine is introduced but face a higher price of food because of the stronger demand of food from vaccinated consumers.

Perceptions of “Organic” Food: A View Through Brand Theory

Globally, the organic food industry has experienced impressive growth rates, especially in the United States and Europe, yet still accounts for a relatively small portion of total food sales. In the United States, it constitutes less than 5% percent of food sales despite a decade of support by the U.S. National Organic Standard. Using the United States as a context, the authors show through survey data and confirmatory factor analysis that when “organic” is examined through the lens of brand theory, it is clear that it has yet to attain brand equity. There is evidence of brand awareness and perceived quality, suggesting that the industry has moved in the right direction. Yet negative perceptions of value and no evidence of brand loyalty undermine the industry’s goals. Because “organic” carries different significance to different consumers, the industry will have to develop a cohesive strategy to reestablish “organic” in a unified way. For country markets of similar experience with organic food, and for markets just beginning to consider consumer interest in organic food, these lessons from the United States offer guidance for policy and marketing strategy.     

Multifunctional peri-urban agriculture—A review of societal demands and the provision of goods and services by farming

Peri-urban areas around urban agglomerations in Europe and elsewhere have been subject to agricultural and land use research for the past three decades. The manner in which farming responds to urban pressures, socio-economic changes and development opportunities has been the main focus of examination, with urban demand for rural goods and services representing a driving factor to adapt farming activities in a multifunctional way. Working within the peri-urban framework, this review pays particular attention to the relevance of multifunctional agriculture. Academic discourses and empirical insights related to farm structure and practices beyond conventional agriculture are analysed. Diversification, recreational and environmental farming, landscape management and specialisation, as well as direct marketing are all taken into consideration and discussed within the context of landscape functions. The provision of rural goods and services is contrasted with societal demands on peri-urban agriculture. This review finds that multifunctional agriculture has been commonly recognised in peri-urban areas – a phenomenon that includes a large variety of activities and diversification approaches within the context of environmental, social and economic functions of agriculture. In response to the post-productive, consumption-oriented requirements of the urban society, peri-urban farmers have intensified their uptake of multifunctional activities. Nevertheless, not all multifunctional opportunities are being fully developed when one considers the large and growing urban demand for goods and services provided by agriculture carried out near the city. This paper discusses policy and planning approaches to support multifunctional agriculture in peri-urban areas.     

Branding Food Culture: UNESCO Creative Cities of Gastronomy

ABSTRACT

Although branding is a well-established practice in consumer goods marketing its application to intangibles is a relatively new activity. This article analyzes the co-branding between the United Nations and urban centers that are successful in becoming UNESCO Creative Cities of Gastronomy. Cities with this status have the potential to generate benefits from enhanced brand image, with associated economic and social rewards. However, it requires ongoing investment to create awareness among potential tourists and investors and in the development of enhanced pride and coordination among city residents and businesses. Numerous cities are likely to join the existing five UNESCO Creative Cities of Gastronomy over coming years as a result of efforts from UNESCO to raise its profile, alongside individual cities prioritizing food tourism in their economic development plans and increasing global importance of food security as evidenced by it being the theme for World Exposition being hosted by Italy in 2015.     

Domestically produced food: Consumer perceptions of origin, safety and the issue of trust

It is becoming increasingly difficult for the public to attempt to assess risks using traditional methods such as smell, taste or other physical attributes of food. The existence of extrinsic cues such as the country of origin (COO) of food can help to make food purchase decisions easier for consumers. However, the use of extrinsic cues depends heavily on the extent to which consumers trust such signals to be indicative of quality or safety, which in turn depends on the credibility behind that cue. This paper aims to examine consumers association of domestically produced food with increased food safety standards and the association of COO and food safety information with socio-demographics and other aspects of consumer psychology such as attitudes, risk perception and trust. Using an ordered probit model, domestic production is examined as an extrinsic cue for food safety by looking at the relationship with trust in food safety information provided by national food standards agencies (NFSAs) and other socio-demographic characteristics, based on nationally representative data from 2725 face-to-face interviews across five European countries. Results suggest that domestic production of food is an extrinsic cue for food safety and as consumers place increasing importance on food safety they are more interested in food produced in their own country. This, coupled with consumer trust in a strong, and independent national food standards agency, suggests the potential exists for the increased consumption of domestically produced foods.     

German and British Consumer Willingness to Pay for Beef Labeled with Food Safety Attributes

The European Union has implemented some of the most stringent food safety policies for beef globally, ranging from banning growth hormones to mandating country of origin labeling. Using choice experiments and random parameter logit models, we examine German and British consumer willingness to pay (WTP) for American, Canadian, Argentinian, French, German and British beef, quality assurance seals, hormone‐free beef production and a gourmet label. We also determine how consumer WTP for these food safety and quality attributes is affected by the extent to which consumers consider food safety issues (FSI). Results indicate that British consumers had the lowest WTP for beef from Argentina and German consumers had the lowest WTP for beef from Great Britain. The hormone‐free label was the relatively most preferred label by consumers in both countries, and by those who considered FSI to affect their meat consumption patterns.     

我国农业生产中粮食质量安全问题分析

目前,我国农业和农村经济、社会事业取得了长足的发展。随着粮食的持续增产,粮食生产总量已基本满足消费需求,但是由于过分依赖施用化肥、农药来增加产量,以及重金属污染等,存在一定的质量安全隐患的问题。所以,在重金属污染和农药残留相当严重的情况下,粮食质量安全成为我国农业发展的迫切需求,特别是伴随着城镇化、工业化的迅速推进,粮食安全不容忽视。笔者提出国家的顶层设计应把“粮食质量安全”作为 “关注民生”的重要内容;大力培育农业生产者 “健康农业”意识,提高操作技能把;加强农业生产要素的质量监测,并通过立法手段确保农业生产资料的质量安全等。     

信任对城市居民有机食品消费行为的影响机理分析

[目的]揭示不同信任水平消费者在有机食品消费行为上的差异及其内在逻辑,从而为有效破解有机食品市场提供新的思路。[方法]文章以价值感知和食品安全意识为中介调节变量,构建信任影响消费行为的分析框架,并基于全国1 113位城市居民的微观调查数据,采用Ologit模型进行实证检验。[结果]信任水平正向影响居民有机食品消费行为和价值感知,价值感知在信任对消费行为的影响中发挥中介效应;同时,居民食品安全意识在信任与价值感知之间起调节作用,从而价值感知对信任与消费行为之间关系的中介效应也会受到食品安全意识的调节,即产生了被调节的中介效应。[结论]信任是决定消费者有机食品消费行为的重要因素,信任缺失会限制消费者的购买行为。利用有效的信号揭示和传递机制能缓解市场信息不对称,增进消费者信任,从而促进有机食品消费市场发展。与消费者信任相比,价值感知是影响消费者购买行为的更为直接的因素,不同消费者信任水平导致的购买行为的差异,在一定程度上是通过影响消费者价值感知实现的。因此,提供差别化的产品与服务、加强消费者的良性社交互动,普及和传播食品安全知识,有效提升消费者的价值感知水平和食品安全意识,都有利于有机食品市场培育。     

Food commodity price changes and consumer welfare in Bangladesh: Valuable lessons for today

The recent rise in global food prices threatens many countries worldwide, especially the vulnerable populations. Viable coping strategies can only be designed based on the important policy lessons learned from the experiences of these countries in confronting the similar shocks of 2007–2011. However, the disproportionate effects of these events and the impacts of policy responses remain largely unexplored. We examine the impact of a food price surge and the effectiveness of various mitigating policies in Bangladesh, one of the most populous, densely populated countries in the world that is plagued by poverty. Specifically, we combine individual-level expenditure survey data with recent advances in consumer theory to examine the welfare consequences across income groups and geographic areas of the country over 2000–2016. Our empirical findings lend support to the hypothesis that the brunt of the price surge was borne by relatively less affluent and rural households, and government poverty alleviation programmes were largely ineffective.     

The welfare cost of Japanese rice policy with home‐good preference and an endogenous import price

The welfare cost of Japanese rice policy is estimated in the context of a large importing country, treating domestically produced rice and imported rice as heterogeneous goods and where there is home‐good preference. Not accounting for this preference will cause the gains from liberalisation to be overestimated. The period that is analysed is 2004–2007, departing from that in previous studies, which do not cover this period of greater deregulation. Rather than use border trade flow data as is customary, we acknowledge the actions of a state trading enterprise and construct and use a unique data set which should better gauge import penetration in the Japanese market for rice. Econometric estimation fails to reject the hypothesis that the Ministry of Agriculture, Forestry and Fisheries prevents imports from affecting the price of domestically produced rice. In the absence of precisely estimated parameter values, simulations of liberalisation are conducted under a range of parameter values and the effects on social welfare calculated. The tariff equivalents of the government's support to rice producers are also estimated with values for the period in excess of 100 per cent.     

On the Consumer Value of Complementarity: A Benefit Function Approach

The article develops a conceptual model of the consumer value of complementarity and illustrates its usefulness in an application to fisheries. Complementarity arises when some goods have a positive effect on the marginal value of other goods. We propose a measurement of the value of complementarity based on the benefit function. Our econometric analysis of fish consumption in Italy examines these issues, with special attention given to dynamics. Our results show that, while short-run fish demand is characterized by substitution relationships, complementarity does develop in the intermediate run and in the long run.     

Producer–Consumer Misalignment as a Possible Cause for New Food Failure: Empirical Evidence From Chile

Literature on new food products development agrees on the importance of gaining knowledge about consumer tastes and preferences as a way to increase new product success. However, the failure rate of new food introductions continues to be high. In economies with a highly developed retail system, retailers and other market players create an information and communication barrier between the producer and the consumer. Consequently, the development of new products becomes difficult in such conditions, since misalignments between producers and consumers are more likely to occur. To investigate the issue, we interviewed producers of Chilean companies in the blueberry, plum, and wine industries and concluded that their product design was based on assumptions about consumers’ preferences and on the observed market response to competitors’ products. To test if these assumptions were correct, we compared them to consumer preferences. Results showed that producers’ assumptions about consumer preferences differ significantly from actual consumers’ preferences.     

Reputations, Market Structure, and the Choice of Quality Assurance Systems in the Food Industry

Many food traits desired by consumers are costly to provide and difficult to verify. A complicating factor is that delivered quality can only be affected stochastically by producers and imperfectly observed by consumers. Markets for these goods will emerge only if supplying firms can be trusted. We develop a repeated purchases model to explore how quality discoverability, market structure, nature of reputations, market premiums, and discount factors drive firm choice about the stringency of quality assurance systems designed to gain consumer trust. Reputation protection is key incentive for firms to invest in high-quality goods and quality assurance systems.     

Consumer Attitude towards Organic Labeling Schemes in Japan

ABSTRACT

Japan is the most lucrative organic market in the Asian region and is projected to account for about 80% of the Asian market revenues by 2009 (Kuhlmann and Jones, 2006). This study identifies Japanese consumer preference and interest in two major labeling information- source of organic certification/traceability and country of origin for organic food products. Stated preference method (SPM) based survey data was collected from two major cities in Japan in order to develop Japanese consumers' organic food choice model. Findings show that Japanese consumers are willing to pay 10% price premium for the organic food products compared to conventional products that have no specific labeling, suggesting a significant profit margin to be possibly captured by the organic producers and marketers. The Japanese consumers have perceived value of the JAS label in their stated preference and showed willingness to pay a price premium for this quality certification system, which validates the importance of government-regulated mandatory labeling. Regarding the country origin labeling issue, the Japanese consumers showed clear preference for the domestic organic products to the imported products, while showing no preference for any particular country origin for imported organic products. For private-voluntary organic labeling, the consumer organization-led organic label is considered to be more reliable source than the retailer-guaranteed organic label.
