Policy Development for Novel Foods: Issues and Challenges for Functional Food

Challenges in policy development for novel foods arise from information asymmetry associated with these credence goods. Policy development reflects pressures by firms and investors to apply health claims in marketing functional food, nutraceuticals and natural health products, which are growing market segments, relative to mature food markets. However, the wordings on health claims are often misinterpreted by consumers. Despite tendencies for some convergence in approaches to health claim policies, policy differs internationally. Related issues considered include factors influencing consumer preferences for these products and uncertainties in the markets for them.

Fruit and Vegetable Consumption Patterns: A Segmentation Approach

In this article, we study the heterogeneity of fruit and vegetable consumption patterns in France. A finite mixture of AIDS models is used to describe food demand patterns revealing different preferences over distinct classes. We obtained six different clusters, which reflect specific socio-demographic characteristics and different income and price elasticities. This approach is appropriate for targeting specific public nutritional policies. Our main results show that unlike the other clusters in which the usual price and income policy tools may be used, the lowest income cluster with the lowest consumption, remains insensitive to economic variables.     

Policies Supporting Organic Food and Farming in the EU: Assessment and Development by Stakeholders in 11 European Countries

There is no single ‘best way’ of policy development. Bottom-up approaches to policy design and a broad debate among stakeholders facilitate policy learning and innovation. A novel approach of a bottom-up policy design process involving stakeholders is introduced. The first results obtained by implementing this methodology are presented. The outcomes of a large international effort for a development of policies for organic food and farming, which took place in Maj 2004 in Europe, are analyzed: the synthesized results from 11 European countries (AT, CH, CZ, DE, DK, EE, GB, HU, IT, PL, SI) on the current situation of policies related to the organic food market in Europe are highlighted and policy recommendations for the development of the organic food and farming sector are formulated. Specifically, strengths, weaknesses, opportunities, and threats of policies related to the organic food market are identified and policy instruments used to address these aspects are developed.     

Changing food consumption patterns in rural and urban Vietnam: Implications for a future food supply system

Rapid income growth and urbanisation could significantly change the composition of the food basket in many emerging economies. This study estimates a demand system, including 15 major food items in Vietnam, with multiyear household survey data. We find a large variation in the estimated price elasticities (–0.05 to –0.88) and expenditure elasticities (–0.16 to 2.56). Food types, urban status and income groups can explain this variation. We also find that the staple food, rice, is already an inferior good for rich urban households in Vietnam. Moreover, food preferences are evolving away from rice but towards animal proteins (fish, pork, chicken, eggs and milk), fruits and vegetables, irrespective of urban status and income groups. As the Vietnam economy continues to grow with a doubling of gross domestic product (GDP) in the next decade, per capita rice consumption in both urban and rural areas and across different income groups will continue to decline, whereas demand for other high‐value products will rise. Thus, government policy should focus on encouraging demand‐oriented food production. In addition, crop diversification at the farm level needs to improve substantially to meet the rising demand for these food products due to income growth and urbanisation.     

Organic‐ and Animal Welfare‐labelled Eggs: Competing for the Same Consumers?

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.     

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.     

The microeconomics of the developmental paradox: on the political economy of food price policy

A longstanding puzzle in comparative economics is the ‘developmental paradox’, the tendency for government support for agriculture to increase with national income and to decrease with the proportion of economic activity and of the population in agriculture. This paper offers a microeconomic explanation for that puzzle. It establishes analytically the microeconomic basis for coalition alignments with respect to food price policy, then numerically simulates the comparative static effects of alternative food policies on coalition structure. A parsimonious household model applied to a heterogeneously endowed society demonstrates how variation in individual welfare effects might beget distinct coalitions in the debate over food price policy and how those policies are inextricably linked to land, population, and technology policies in food agriculture. Moreover, coalition alignments on particular policy debates are path-dependent. In particular, food price policy creates its own political support.     

Nutrition Transition and Changing Food Preferences in India

We present empirical evidence on how changes in food preferences have contributed to nutrition transition, where the dietary pattern of households shifts away from traditional staples. Using household-level time series cross-section survey data for India, we estimate time varying demand elasticities, revealing evidence of the declining importance of cereals in Indian household diets. The estimates show that Indian demand for cereals has become more income inelastic and price elastic. We also find that cereals are a substitute rather than a complement to animal products in household diets. Since changes in elasticities can only be attributed to variation in utility parameters, this indicates that cereals are losing favour with Indian households. These findings have implications for Indian food policy design and implementation.     

Consumer Motives and Purchase Preferences for Organic Food Products: Empirical Evidence From a Consumer Survey in Bangalore,South India

ABSTRACT

Consumer organic food choice motives and purchase preferences were studied in a structured quantitative survey (N = 201) in Bangalore, with the aim of identifying consumer segments based on these motives and preferences. Further, sociodemographic differences between the clusters were studied. Face-to-face interviews were used to sample the data, which were analyzed with factor and k-means cluster analysis (SPSS 16.0). Five latent factors were identified based on the motives, representing a set of consumer concerns labeled here as “food phobia” (health),” “environment,” “humanity,” “healthy eaters,” and “control.” Further, three clusters emerged from these motives representing 38%, 37%, and 25% of the sample size. The factors differ in terms of variance. Here, the records of perceived healthiness (food phobia) were the most important element, explaining 18.37% of the total variance. These clusters were differing in terms of the level and order of motivations. The health factor was a most important motive in two clusters, followed by environment. Further, humanity was the most important motive for the third cluster. This may reflect a heterogeneous nature of consumers in study area. Additionally, five clusters were identified based on the preferences, and profiles of these clusters differed in terms of sociodemographic factors and consumption pattern. Segments were identified based on motivating factors and preferences, and linking them with food choice motives and products preference provides the input needed by marketing professionals and policy makers to calibrate more efficient marketing strategies to better focus and position their products and design their communication strategies for target segments.     

The Evolution and Implications of the U.S. Food Security Act of 1985

The Food Security Act of 1985 sets the United States (U.S.) policy course for the five years, 1986–1990, in the areas of farm product prices and farmer incomes, agricultural production, food aid, and trade in agricultural products. It is clearly an evolution of past policy, deeply rooted in the institutional processes of participatory policymaking. The Act will have important implications for not only domestic producers, consumers, agribusinesses, and taxpayers, but alto product agricultural exporters and importers around the world. Just as it was substantially, affected by the current loss of export markets and the economic crisis in the U.S. agricultural sector, its implementation and impacts will be affected in the future by the unpredictable weather, macroeconomic conditions around the world, and international trading policies. This article examines the development of the policy embodied in the Act and analyzes its primary economic implications. Although most provisions of the U.S. agricultural price and income policy that had evolved over the past half century were continued, important changes were made. The resulting policy closely mirrored the preferences revealed from research concerning farmers and leaders of national agricultural and food interest groups. Primary changes from the previous 1981 Act were: lengthening the duration to five years; substantial lowering of the minimum price support levels; permitting a gradual decline in the minimum target prices; providing for a whole dairy herd buyout program; establishing export enhancement initiatives through credit, promotion, and export payment-in-kind (PIK); and initiating major efforts to increase farmland conservation and withdrawal of fragile lands from production. Likely implications of the new Act include: (1) lower product prices for agricultural producers around the world, and also farmer incomes if there is no income protection from national policies; (2) a similar but a less proportionate impact on consumers; (3) a substantial burden on the U.S. Treasury, and possibly those of the other nations as well, depending upon the type of policies followed; and (4) likely intensification in the immediate future of the economic conflicts and negotiations between major agricultural trading nations of the world. Research played a vital role in the development of the U.S. 1985 Act. Given the turbulent, uncertain, and important nature of the agricultural and food sector in the world, research is challenged to provide more and better knowledge for future policymaking.     

Modelling the impacts of policy on entry into organic farming: Evidence from Danish–UK comparisons, 1989–2007

This paper analyses organic farming entry decisions using a piece-wise linear depiction of policy. Our goal is to ascertain, from the available but limited information, whether Danish and UK policy measures toward organic agriculture have affected participation. Despite considerable interest in the growth of organic farming there has been little systematic analysis of it, although it is commonly believed that enhanced income levels have played a part. Whilst analyses of organic farming policy have provided extensive reviews of instruments applied, generally speaking, the spirit of those enquiries takes as datum that organic policies have had the desired impacts. Yet such conjectures remain mostly untested. Hence, there is a need to examine systematically if there exist relationships between the introduction of organic farming policies and the growth of organic farming, and whether particular policy measures are more effective than others. Here, we take a first step in this endeavor by undertaking an econometric analysis of the relationship between 14 organic farming policy measures and participation rates in Denmark and the UK during 1989–2007. Using two response variables – the numbers of farmers converted to organic production and the total land area under organic practice – we implement a simple, Bayesian methodology and evaluate the stepwise-linear impacts of policy. Extensions for future work are discussed. Six policy measures in the two study countries were found to be significant influences on participation, five of them direct supply-side instruments. For the UK, all of the policies are annual subsidies for organic farmers once conversion was complete. For Denmark, the policies are the introduction of organic subsidies for non-dairy farms, the extension of subsidies beyond 1997 and support for the costs of marketing services.

The Influence of Consumer Characteristics and Attitudes on the Demand for Organic Olive Oil

Abstract

The aim of the present study is to examine consumer factors that affect the demand of organic olive oil (socioeconomic characteristics as well as attitudes towards organic products, food safety and the environment). Heckman approach for single equation procedure was applied in order to (1) identify the profile of regular buyers of organic olive oil based on the aforementioned factors and (2) to estimate income elasticity for the same product. Results indicate that the demand for or ganic olive oil is strongly affected by socioeconomic characteristics such as income size and occupation status, and to a lesser extent by attitudes towards organic products, food safety and the environment.     

Agricultural Biotechnology: A Comparison of Consumers' Preferences for Selected Policy Options

This paper reports on a study of consumers' preferences for regulatory policies that relate to food biotechnology. Data on consumers' choices of selected policy options were collected through a telephone survey of Alberta residents conducted in early 2000. Conditional and mixed logit models were developed and tested. These assess the influence of different socio-economic factors on respondents' choices of particular policy options and are used to estimate respondents' willingness to pay for two policy options that were the major focus of the study, specifically:

Measuring the relative importance of preferences for country of origin in China, France, Niger, and the United States

Recent labeling policies in developed countries place new focus on origin labeling, especially country of origin labeling, for a variety of food products. It is not clear if this new emphasis on origin is the result of more ethnocentric consumer preferences for food. We measure consumer preferences for country of origin in four different international locations and one domestic control location using a conjoint experiment to test the null hypotheses that consumers do not have stronger own-country preferences. In addition, we compare the relative importance of consumer preferences for origin to their preferences for genetically modified food and pesticide-free production using attribute coefficients from within location ordered probit models. The study was conducted in China, France, Niger, and the United States. We find consumers tend to prefer food from their own location indicating ethnocentric tendencies do play a role in shaping country-of-origin preferences. Country of origin is generally less important to consumers than genetically modified food content and pesticide use in food production.     

The Survey of Heterogeneity on Organic Products Consumers’ Preferences Using Mixed Logit and Latent Class Models

Abstract

Today, the importance of consumption of organic products has become more evident to the consumer due to the great benefits of these products. The aim of this study is to investigate the factors affecting the preferences of organic tea consumers in Tehran by considering the heterogeneity of consumer’s preferences. For this purpose, mixed logit and latent class model were used. The required information were collected through field surveys by completing a questionnaire from 405 respondents from Tehran citizens in 2016. Results from estimating mixed logit and latent class models confirm the heterogeneity of preferences between consumers. Different levels of income, education, age, history of poisoning and awareness of organic products were identified as heterogeneous factors. The results of the estimation models showed the maximum willingness-to-pay is related to the attribute of the disease and long-term effects. According to the findings of the study, it is suggested to help increase people's awareness of the characteristics of organic products and the use of targeted-oriented strategies to encourage consumers to consume organic products.     

Food Preferences and Ethnicity

Policies to curb food imports in food deficit Sahelian countries have been unsuccessful. Sahelian countries are ethnically diverse and each group has demonstrated strong preferences for cereals and other foods. Yet, research on the consequences of expressed food preferences on food production, consumption, and importation is limited. In this paper, the effects of ethnic identity and income class on food consumption choices were investigated. The results showed that all consumers, use the same criteria in evaluating a given set of foods irrespective of ethnic group, or income class. Ethnic groups and income classes choose a given food basket, which maximizes their welfare, if the same criteria are used in making their food choices.

关于实施土地流转补贴政策的研究

研究目的:通过实施土地流转补贴政策,扩大农户经营规模,保证农户增收。研究方法:规范分析法。研究结果:土地流转补贴政策的内容包含政策的指导思想、目标、原则、范围、对象、规模、标准、申报审核、资金发放、监管等10个方面。研究结论:中国现行各项农业直接补贴政策在保障国家粮食安全方面效果较为明显,在增加农民收入方面效果不大。实施土地流转补贴政策,促进农户增产增收,利于改进农业生产方式,利于解决农业劳动力老龄化问题,促进劳动力转移。实施土地流转补贴政策必须克服过度扩大经营规模和引入非农经营主体的错误倾向,由国家进行规范,并通过农村社会保障制度的建设来推动。
