Food scares, advertising, and the demand for meat cuts in Great Britain

Retail demand systems for 19 different cuts of meat for beef, lamb, pork, bacon and poultry in Great Britain are estimated from monthly time series of consumer expenditure from 1989-2000 using a two stage budget allocation process and an LA/AIDS specification. The unconditional expenditure, own and cross price elasticities are derived for the individual meat cuts. The impact of adverse publicity from meat scares, especially BSE, and of positive publicity through consumer promotion and advertising are incorporated into the modelling. Meat scares produced a reallocation of consumer spending from red to white meats during the 1990s. The impact of species-based advertising was shown to have complex spillover effects both within and between meat species, and the response of consumer demand to advertising was considerably less than to adverse publicity.     

Farm work, off-farm work, and hired farm labour: estimating a discrete-choice model of French farm couples' labour decisions

We model jointly several types of discrete-choice labour decisionsof farm couples: farm work, off-farm work and hired farm labour.Rather than estimating a set of reduced-form participation equationsthat is subject to an internal inconsistency problem, we estimatea 16-choice multinomial model. We find that farm labour of operatorsand of spouses are substitutes. Hired farm labour increaseswith the farmer's qualifications, perhaps substituting for thecouple's labour inputs. Other adults in the household substitutefor the farm labour input of the farm couple and hired workers.We find that the organisation of work by French farm householdshas changed over time, in the direction of a more equal sharingof tasks and responsibilities between members of the farm family.     

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.     

The Demand for Organic and Conventional Produce in London,UK: A System Approach

The majority of studies on consumer demand for organic products neglect the presence of non‐organic competitors, ignoring their effect on consumer demand for organics. This article uses a demand system which includes both organic and non‐organic fruits and vegetables, with actual (as opposed to stated) data for household purchases. Estimation of our model provides empirical evidence on the interrelationships between organic and non‐organic products, as the relevant cross‐price elasticities. Own‐price elasticities indicate that organic fruits and vegetables are more price elastic than their non‐organic counterparts, and that lower social class households with children have the most own‐price elastic demand. Cross‐price elasticities indicate relatively strong loyalty to organic products.     

International Marketing of Organic Foods: Consumers,Standards, and Harmonization

Differing technical standards can be barriers to international trade. Harmonizing standards is one means of removing barriers to trade. It is argued in this article that international harmonization may not be welfare enhancing if consumers have a strong attachment to their domestic standards. Standards for organic products differ among countries and act as a barrier to trade. International harmonization has been proposed. Consumers were surveyed in the United States, United Kingdom, and Canada to determine their likely attachment to existing domestic organic standards. The results suggest that consumers, even those with a preference for organic foods, have little understanding of their domestic standards and only weakly identify with them. As a result, harmonization could be pursued. Agribusiness firms that are interested in harmonization to expand their access to export markets should promote the development of a new international standard rather than harmonization to one of the existing domestic standards.     

The Theory and Econometrics of Health Information in Cross-Sectional Nutrient Demand Analysis

Understanding the role of health information in food and nutrient demand has become an important issue over the last decade. Endogeneity and measurement error are two empirical problems that are inherent in this type of analysis. While some type of instrumental variables estimation would appear the obvious solution, this article provides several theoretical and empirical reasons why this is not the case in cross-sectional analysis. An alternative estimation strategy is pursued, an empirical example is given, and the implications are discussed.     

The Challenges of Organic Production and Marketing in Europe and Spain: Innovative Marketing for the Future With Quality and Safe Food Products

In this work the actual situation of organic production and marketing in Spain is explained, studying and analyzing their evolution in the last decade of previous the century and in the first years of the new millennium. In Spain, organic production began in the 1970s with pioneers in Catalonia, Murcia Region, and other zones. It was in the 1990s when was observed a great increase in organic surfaces. A very interesting and critical date is that at the moment, more than 80% of organic products are being exported to other European countries, United States, and other foreign markets, and it is necessary to find new marketing strategies and innovations to structure the organic market, give new information to consumers, improve investments in the relation between retailers and consumers, and improve the perception of the utilities of these products. In some countries, as is the case of Spain, the consumers don't have enough information about the characteristics of organic products, organic food, and organic production methodologies. They must have all the information about the benefits of organic production methodologies and their implications in environmental conservation, biodiversity protection, food quality and safety, and this task must be provided by the new marketing strategies and actions.     

The Influence of Trust and Attitudes on the Purchase Frequency of Organic Produce

Growth in organic food sales is mainly due to consumers becoming more aware of health issues and environmental concerns. Understanding the drivers of organic consumption is crucial to predict future market outcomes. In this analysis, the authors expand previous research by including general and institutional trust variables in addition to consumer attitudes to examine organic food purchases. Food production is unobservable and hence, consumers need to exhibit trust with respect to organic production and certification. A bivariate ordered probit model applied to U.S. survey data confirms that organic purchases are determined by health, nutrition, and taste. In some cases, general trust and trust in media are statistically significant. Trust in institutions that are involved in the organic certification process is not statistically significant. A hierarchical cluster analysis grouping consumers based on trust and attitudes shows that (dis)trust in the organic certification and supply chain does not hinder organic food market growth.     

The Fast Decay Process in Outdoor Recreational Activities and the Use of Alternative Count Data Models

Despite a number of significant advances in count data modeling during the last two decades and the growing popularity of these models in recreation demand analysis, standard count data models are inadequate to address the fast decay process of the dependent variable and the associated long tail. This article demonstrates how one and two-parameter alternative count data models can be used to properly model the fast decay process and the associated long tail commonly observed in recreation demand analysis. Econometric results from an illustrative application suggest satisfactory performance of four of the eight alternative count data models proposed in this article.     

Government Expenditures,Health Outcomes and Marginal Productivity of Agricultural Inputs: The Case of Tanzania

This paper examines the impact of health expenditures on agricultural labour productivity in order to inform the necessary policy decisions about targeting scarce public resources towards their most effective uses. We link health sector expenditures in rural Tanzania to health outcomes and agricultural labour productivity using data from the 2008 Household Budget Survey (10,975 households) and the 2007/08 Agricultural Census (52,594 households) across 113 districts in Tanzania. The results indicate that the marginal productivity of labour as well as land and fertilisers respond significantly to health expenditures. However, the magnitude of the response varies across types of disease, categories of expenditures and agricultural inputs. These findings suggest both the need and scope for targeting public expenditures in the health sector to achieve better agricultural growth outcomes.     

Impact of Purchase Intentions on Full and Partial Bids in BDM Auctions: Willingness‐to‐pay for Organic and Local Blueberries

We conduct a series of Becker–DeGroot–Marschak (BDM) auctions to elicit consumers' willingness‐to‐pay (WTP) for organic and local blueberries. Participants' intentions to purchase the auction product were collected to determine how purchase intentions for the auction products affect their partial bids (WTP for an additional attribute) as well as full bids (WTP for the auction product). The results suggest, as expected, that full bids from participants with purchase intention for the auction product are significantly higher than those from participants without purchase intention. However, the partial bids, which are inferred from the full bids, for organic and local attributes are consistent across participants with different purchase intentions. Therefore, if the focus of a BDM auction is consumers' WTP for product attributes, purchase intentions may not be an important influence on the value.

An Analysis of Standards‐based Regulation in the EU Organic Sector, 1991–2007

Against the background of a discussion of recent analyses of capitalist subsumption of agriculture and of neo‐liberalism, the paper uses a ‘liberal governmentality’ framework to trace the development of the EU Regulation on organic agriculture from its adoption in 1991 to its recent repeal and replacement in 2007. The central argument is that regulatory development took the form of a cycle of elaboration, tightening, increasing deviation and finally a ‘return to principles’ in order to reduce deviation. At different stages in this cycle, different groups of ‘stakeholders’, including experts, were influential. Likewise, different forms of expertise became dominant or were sidelined. Meanwhile, ‘capital’ in its different incarnations remained marginal throughout. The paper leaves open the questions of the generalizability of this analysis to regulatory arenas other than the EU, as well as to regulatory objects more central than organic agriculture to capitalist accumulation.     

Survey and Analysis of Labour on Organic Farms in the UK and Republic of Ireland

A survey of 1144 organic farms in the UK and Republic of Ireland (IE) was used to assess whether organic agriculture provides more labour than conventional (nonorganic) farming. The sampled farms comprised 23% of all organic farms. The jobs per farm and per area varied greatly with enterprise type and farm size, and between regions. Comparison of the survey with national statistics showed that organic farms employ 135% more FTE (full time equivalent jobs) per farm than conventional farms. The mean jobs per area was markedly lower for organic farms (1.35 compared to 2.43 FTE per 100 ha), because they are larger (216 ha compared to 51 ha). Even when corrected for the different size distribution, organic farms had more jobs per farm than the national averages (2.52 and 1.49 FTE for the UK and IE, compared to 1.28 and 1.16 FTE). The farm size weighted FTE per area for organic farms in the UK (4.33 FTE per 100 ha) was almost twice that for conventional farms. We predict there would be 19% and 6% more farming jobs in the UK and IE if 20% of the farms of both countries were to become organic (compared to the present 1–2%).     

The relationship between food consumption, age and gender over time in Britain

This paper investigates the relationship between nutrition and socio-economic status among British youths. It describes the dynamics of consumption over age and time using data from the British National Food Survey (NFS) covering the period 1975-2000. Daily calories-age relationships for men and women are estimated by solving a non-linear least square model with a roughness penalty function approach. Focusing on young age groups, trends of consumption over the 25-year period of study and the cohorts effect have been explored across three classes of age. Finally, an exploration of specific trend variations in eating habits has been implemented controlling for income distribution.     

农地征用对社会稳定的不利影响及其治理对策——以河北省廊坊市为例

廊坊市作为河北省工业化、城镇化建设的前沿阵地,近些年来农地征用日益增多,对社会的稳定产生了一些不利影响。例如,被征地的农民普遍存在的社会焦虑情绪,容易与相关部门产生冲突等都不利于社会稳定。究其原因主要是由于我国社会正处于转型期,且征地补偿机制不健全,基层组织的社会管理不力。所以应该格外关注失地农民的社会融入,完善征地补偿机制,加强基层组织的社会管理力,以促进和维护社会稳定。

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.     

“营养强化维生素AE”菜籽油中VA、VE的稳定性研究

为了探究"营养强化维生素AE"菜籽油中维生素A(VA)与维生素E(VE)的稳定性,本研究重点考察了高温加热、光照及烹饪对"营养强化维生素AE"菜籽油中VA、VE含量的影响情况。研究发现,高温加热对VA、VE的稳定性影响较大,温度越高、加热时间越长,损失率越大;光照条件下储存VA、VE均有明显损失,避光条件下几乎无明显变化;烹饪过程会导致VA、VE的流失,但低温短时烹饪过程中VA、VE的损失量是可控的。综上可知,"营养强化维生素AE"菜籽油在日常食用过程中最好选择避光储存,避免高温长时间加热,由此可以减少VA、VE的损失。
