This paper employs a latent variable approach to isolate the effects of changing tastes on the share of total meat expenditure on different categories of meat products in Greece during the period 1965–1995. We find that changes in the relative expenditure on different categories of meat cannot be explained by changes in the relative prices of the different meat products and increased expenditure alone. For pork products in particular, the increase in the share of expenditure has been greater than would be expected as a result of the relative fall in their price. The increase can therefore be associated with changes in taste. This finding is of general interest to those conducting empirical research into consumer behaviour both in economies where there have been significant changes in patterns of food consumption, and where, as in the case of many less industrialised economies, rapid structural changes in food consumption patterns are still to come. It is also of importance to policy makers in assessing die effectiveness of advertising or promotional campaigns in influencing longer term changes in consumer preferences for different products.  相似文献

Inverse demand systems explain price variations as functions of quantity variations. This article presents a dynamic inverse almost ideal demand system (AIDS) model based on recent developments on cointegration techniques and error correction model. The case of fish landed at Greek seaports appears to suit this model well. The results indicate that the underlying distance function is homothetic whereas the own-quantity flexibilities suggest that the responses of price to own-quantity changes are inelastic. Finally, the results of cross-quantity uncompensated flexibilities suggest that the substitution possibilities among fish grades are rather limited. The Allais interaction intensities verified the substitutability among fish grades as well.  相似文献

“本”和“末”是中国经济思想史中的一对特定范畴,“本”泛指农业,“末”泛指工商业。所谓“本”、“末”观,就是指古人对农工商业及其相互关系的看法,其中包括“重农轻工商”的观念。古希腊虽然没有与中国相对应的“本”、“末”概念,但却不乏对于农工商业及其关系的思考。本文即选取古希腊的几位有代表性的思想家或立法者作为研究对象,试图对古希腊人的“本”、“末”观进行一些粗略的考察,以期获得一个总体性的认识。本文的基本结论是,与中国先秦的情况相似,古希腊的思想家或立法者无不认为农业是立国之本,工商业居于次要地位,而且,对待“末”业的态度也存在着相对宽容和相对严厉两种倾向。产生这种现象的根本原因在于中希文明所处的相似的历史发展阶段及其社会经济状况。  相似文献

Small economies with a narrow resource base need open international trade more than a large country with a wide range of resources. This paper discusses the role of open markets and trade in development of LDC's. It emphasizes the importance of constitutional law that guarantees basic freedoms of choice as the foundation of open market systems. Governments most useful role in development is to provide essential public services and infrastructure and to provide the legal and economic environment for opportunity, incentives and innovation.  相似文献

Abstract

This paper aims to identify the critical factors that support European food retailers' internationalisation via an investigation of the importance of Dunning's eclectic paradigm advantages (ownership, location and internalisation). Senior managers from seven firms that operate in the Greek food multiple retail sector were interviewed, and three propositions were put on test.

In general, the findings indicate the critical role of the internalisation advantage during the international expansion of European food multiple retailers into that market.

The findings also reveal that this advantage is the main superior and sustainable competitive element that European food multiple retailers possess when competing with local firms. The latter can be considered as an extension to the findings of previous studies that have exclusively emphasised the importance of ownership advantage factors in the course of the retail internationalisation process.  相似文献

This study examines meat consumption in China, the world's largest meat consumer and producer, by considering both meat consumed at home and away from home based upon a diary‐based household survey. The results indicate that income growth leads to beef, poultry, other meat and pork away from home consumption to grow more than proportionally to total meat consumption. We also find that meats consumed away from home grow faster than at home counterparts due to higher income elasticities, suggesting that ignoring meat away from home could significantly underestimate current and future meat consumption.  相似文献

中国是食用油消费大国,又是食用油缺乏的国家,食用油自给率只有35%左右。针对这一严峻形势,自2008年以来,党中央、国务院高度重视油茶等木本油料产业的发展,并将其作为保障食用油安全的国家战略选择。西班牙、希腊在推动油橄榄产业发展进程中积累了许多较为成熟的先进管理经验和技术,两国的管理制度值得我们借鉴。介绍了两国油橄榄产业发展情况和有关政策、措施,提出了推进我国油茶产业和油橄榄产业发展的相关建议,对推动我国油茶等木本油料产业科学持续健康发展具有较强的指导作用。  相似文献

Although meat demand is one of the most studied issues in agricultural economics, our understanding of this phenomenon has been hampered by valid concerns about model specification uncertainty. This article revisits the need for more general theories of aggregate U.S. meat demand. Using a Bayesian averaging of classical estimates approach, we draw comprehensive inferences over 1,048,576 demand systems. We find very little evidence supporting the need for more general theories that include demand determinants beyond prices and expenditures. We find strong evidence in support of symmetry and negativity, but strong evidence against homogeneity, which is consistent with other research.  相似文献

Using urban survey data collected by the authors in 2001–02, this paper analyses demographics, cultural factors and purchasing behaviours influencing the consumption of fresh milk, yogurt, ice cream and powered milk in Beijing, Shanghai and Guangzhou, China. Results from estimation of a double-hurdle model of consumption show that income and marketing channels are the key determinants of milk consumption levels; however, education, advertising and convenience play a more important role in consumption of other dairy products. There is some evidence that milk powder, as a consumer good, may be becoming an inferior product in urban China. Finally, the survey data suggest that the growing sophistication of China's retail sector is influencing consumption of dairy products.  相似文献

We have employed an error-corrected almost ideal demand system (ECAIDS) for major crustaceans at a disaggregated level in the United States. The proposed model can provide short- and long-run price elasticities. This article makes an important empirical contribution by reporting a set of reliable, policy-relevant estimates of the elasticities of demand for crustaceans in the United States. The habit formation behavior was significant only for crayfish. The value pricing strategy and the promotional pricing strategy are expected to benefit the domestic shrimp industry. Increasing prices through various marketing strategies can benefit domestic producers of lobsters and crabs.  相似文献

The need for additional information on household demand for meat and fish in Cameroon is addressed. Probit analysis involving the Heckman selectivity correction procedure is used to estimate the effects of individual and household characteristics on demand for beef, chicken, pork and fish. Results indicate that fish is a relative necessity in Cameroon and is often substituted for beef and chicken by households whose profiles include being of low income levels, having large household sizes, are of middle age and are less educated. Whereas chicken and pork substitute each other, they are each complementary to beef. The profiles of households likely to purchase beef include being married, middle age, educated and of the Muslim faith. Profiles for households most likely to increase their purchases of chicken include being of high income levels and are public sector employed. Some policy implications are provided.  相似文献

The effectiveness of pricing policies depends on the price elasticity of consumption. It is well documented that residential demand for water is influenced by heterogeneity associated with differences in the size of the household and socioeconomic characteristics. In this paper, we focus on household size. Our initial hypothesis is that users’ sensitivity to changes in price is different depending on the number of household members. To this end, we carry out an empirical estimation of urban water demand in Zaragoza (Spain) distinguishing between households with different sizes using data at the individual level. As far as we are aware, this approach to urban residential water demand is new in the literature. The analysis suggests that all households are sensitive to prices regardless of size. A more relevant finding is that small households are more sensitive to price changes.  相似文献
