Are the Mediterranean countries competitive in fresh fruit and vegetable exports?

For many of the countries surrounding the Mediterranean Sea, fruit and vegetables are very important products. In light of the increasing trade liberalization and thus increasing competition between countries, this paper aims to investigate the competitiveness of ten Mediterranean countries with respect to fresh fruit and vegetables. The analysis rests on two foundations. First, a set of indicators are calculated to give a general impression of trends and potentials. Second, a constant market share analysis is performed where the countries' competitiveness in world trade is investigated. The results show that the competitiveness of the investigated countries has deteriorated over the period.

Consumer Preferences and Customer Satisfaction Analysis: A New Method Proposal

The organic food market is currently the fastest growing food sector in the United States, with growth rates in organic food sales averaging 17% per year between 1998 and 2006. The largest segment within the organic market is fresh produce, comprising 34% percent of retail sales in 2006. This analysis focuses on identifying the demographic characteristics of households buying organic vegetables (in total) along with prepackaged organic salads and organic carrots, by examining the factors that influence the probability that a consumer will buy organic vegetables, and which factors influence the household share of organic vegetables purchased. We use Nielsen Homescan data for the year 2004. Households with high levels of education are more likely to purchase organic vegetables, while the probability of purchasing organic vegetables is lower for African Americans and for older households.     

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.     

Determinants of Fresh and Frozen Fruit and Vegetable Expenditures in Turkish Households: A Bivariate Tobit Model Approach

In this study, we have identified the effects of socio-demographic and economic factors of household heads and households on monthly expenditures of fresh and frozen fruit and vegetable in Turkey using the bivariate Tobit model. The results show that both the probability and monthly spending levels of household fruit and vegetable consumption increase with increasing in age of household heads, educational levels of household heads, married household heads, household income, and the number of adults in a family, while male-headed households, working household heads, the households that receive in-kind help from the government or private sector, and the use of internet at home decrease both the likelihood and spending levels of fruit and vegetable consumption in Turkey. The results in the study may contribute to the stakeholders to identify and implement effective marketing strategies and also develop more effective policies for the government to improve nutritional levels for certain dwellings for which the government include them in the certain state-initiated benefit program.     

The EU entry price system for fresh fruits and vegetables – Paper tiger or powerful market barrier?

The EU protects EU growers of 15 kinds of fresh fruits and vegetables against international competition by the entry price system (EPS), which is designed to restrict imports below the product-specific, politically designated entry price level. This study investigates the relevance of the EPS per product and country of origin. We develop two indicators for the effectiveness of the EPS, which serve as variables in a cluster analysis identifying four classes differing in the relevance of the EPS. The relevance of the EPS is found to be heterogeneous among products as well as countries of origin. It is highest for artichokes, courgettes, cucumbers, lemons, plums and tomatoes. The influence of the EPS on apples, clementines and pears is significantly lower, and of least relevance for apricots, mandarins, oranges, peaches and nectarines and table grapes. The EPS has the greatest effect on countries which neighbour the EU, whereas it is of minor importance for exports from far-away countries with the exception of China and South Africa.

论我国废弃农产品的治理——以废弃蔬菜为例

针对我国大量废弃农产品造成的环境污染、食品安全与资源浪费等问题,以蔬菜为例,从供应链主要环节分析废弃蔬菜产生的原因,即粗放的生产模式、落后的流通方式与不良的消费习惯、缺位的回收处理法制与利益。通过借鉴国外发达国家处理废弃农产品的主要经验,从出台废弃蔬菜治理法规及政策、构建社会共治体系、鼓励净菜生产及改进流通方式、健全废弃蔬菜回收利用的市场机制,以及依托政府开展第三方专门回收处理等角度,提出减控我国废弃蔬菜的具体对策,为改善我国废弃农产品回收处理现状提供了参考。     

Information and consumer perception of the “organic” attribute in fresh fruits and vegetables

Using a double hurdle model on panel data from 3,200 Danish households (monthly observations for 2002–2007), we study the effects of health‐related media information on the demand for organic fruit and vegetables. We find that “negative” information about pesticides contained in conventional fruit and vegetables mainly influences the probability of a consumer entering the organic market, not the quantities consumed by households that are already active on the organic market. “Positive” information that links health and the consumption of organic food influences both steps of the decision process. Our dataset includes information about consumers’ media habits, which allows us to disentangle the direct effects of media information from the indirect effects of this information as it is disseminated through the population. Our results suggest that directly obtained information is the main type of information influencing consumers, while information loadings by dissemination through the population have almost no effect on consumption.
