ABSTRACT

A component of the supply management policy governing the Canadian dairy sector is a requirement that all milk and cream sold in Canada be sourced from Canadian producers. Cheese, yogurt, and ice cream, however, can be made using imported milk components. Recently, the Dairy Farmers of Canada launched a 100% Canadian Milk label for products that contain only milk and milk ingredients produced in Canada. Featuring a discrete choice experiment, a Canada-wide survey of dairy consumers is used to elicit their willingness-to-pay for milk and ice cream carrying the 100% Canadian Milk label. The results show that Canadian consumers are willing to pay more for milk and ice cream products that carry the label. Consumer knowledge of the dairy sector affects their willingness to pay for this labeling information. Implications for the use of the Canadian origin label and suggestions for further research are discussed.  相似文献

Economic and financial feasibility of projects that are being presented for potential funding by financial agencies depend, among others, on the soundness of assumptions made about the niche in the market which the contemplated enterprises are to fill. This type of market share forecasting is particularly hazardous for entrepreneurs in less developed countries (LDCs), who aim at penetrating export markets for non-traditional agricultural commodities. In this article the author: (a) reviews the methodology used by an Uruguayan enterprise, which decided to export summer citrus to markets in the Northern Hemisphere; (b) shows how these procedures for market share forecasting could be readily adapted to preparation of feasibility studies for enterprises aimed at penetrating export markets for other non-traditional products; and (c) explores the macro-marketing implications of the case study for off-season export of fresh produce from the Southern Hemisphere to consumer centers in North America, Western Europe and Japan.  相似文献

This article discusses the problematic relationship between Douglas Copland and the new generation of post‐war Australian economists. Copland felt that their view of economic policy was contrary to Australia's best interests. The critique and feud was to last right up till Copland's retirement. The article shows how Copland's views differed from those of inside economists and therefore the official policy line.  相似文献

What Is It About Organic Milk? An Experimental Analysis   总被引:2,自引:1,他引:1  
Auction experiments were used to examine demand relationships and willingness to pay (WTP) for organic, rBST-free, no antibiotics used, and conventional milk. Elasticities showed strong substitute and complement relationships between organic, rBST-free, and no antibiotics varieties. The sum of the latter two's premiums were not significantly different than the organic premium, suggesting diminishing marginal utility for added attributes. Results from a two-stage heteroskedastic tobit model demonstrated that WTP premiums for the varieties differ significantly by demographics and beliefs regarding the conventional version. These suggest market segments for rBST-free and no antibiotics versions could succeed alongside organic, benefiting consumers and producers.  相似文献

In response to increasing concerns about domestic food safety issues, establishing tracking systems in the food industry is mandatorily required under newly launched food safety laws. However, the kinds of monitoring and certification systems that should be set up to ensure practical adoption and the effectiveness of the regulation remain unclear. This study aims to analyze consumers’ preferences for milk traceability, with particular interest in investigating how consumers’ preferences could be affected by monitoring and certification systems of the regarding system. Survey data from a choice‐based conjoint (CBC) experiment are used to achieve this objective. In the experiment, milk is defined by a set of attributes in which we assume that milk traceability can be certified by three entities: the government, an industrial association, and a third party. The CBC data are then analyzed by using the alternative‐specific form of a conditional Logit (McFadden's Choice) model. We found that urban Chinese consumers have a strong desire for traceable milk, but their preference for traceable milk is significantly related to the associated certificate issuers. Currently, the highest willingness‐to‐pay goes to government certificated traceable milk, followed by industrial association certificated and third‐party certificated milks. In the future, however, consumers are likely to give more credit to third‐party certification with rising income and knowledge.  相似文献

Abstract

This study explores the economic benefit from labeling milk and milk products and its impact on the supply and demand for fluid milk. The empirical estimate measures the economic value of milk market segmentation based on consumers' willingness to pay for hormonefree milk. The study uses survey data from Kansas households and applied a Probit model for willingness-to-pay and an ordinary least square model for demand analysis. The empirical results show that as long as consumers are willing to pay a higher price for bSTfree milk society would benefit from milk market segmentation.  相似文献

ABSTRACT

The dairy market is one of the fastest growing agri-food sectors in Kosovo, yet the farm structure is fragmented. The level of productivity is lower compared with European Union levels and shows potential for improvements. The consumption of dairy products is expected to rise due to income growth and segmentation of consumers that would reflect different preferences for low-fat or zero-fat products, products with natural additives, and so on. On the market level, a significant share of the consumed milk and dairy products is imported. This study aims to better understand attitudes and preferences of Kosovar consumer segments toward milk and dairy products. A quantitative survey with 300 consumers was conducted in major Kosovo cities. Applying a reduced version of the Food Related Lifestyle instrument identified three distinct consumer segments: the conservative consumer segment, the socially oriented foodie, and the information-seeking eco-consumer. The latter two segments are especially open to trying new food products and actively search information about food. All three consumer segments show strong consumer patriotism by believing that domestic milk and cheese are safer than imported products and are of higher quality. This indicates the strong market potential for dairy farmers and companies in the Kosovo, which should develop new food products having these segments in mind. The authors explore the strategies that farmers and companies should use to better target these consumer groups and gain greater access to desirable segments.  相似文献
