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.  相似文献

The demand for alcoholic beverages in Spain   总被引:2,自引:0,他引:2  
The objective of this study is to analyze the main determinants of alcoholic beverages consumption at home. Data comes from the latest Spanish Household National Survey, which provides information on expenditure and quantities of different food products by household. Because households are interviewed only 1 week, a large number of zeros have been recorded. Among the existing censured demand models (the double hurdle (DH) model; the purchase‐infrequency model; and the Tobit purchase‐infrequency model, among others) and after carrying out model selection tests, the DH model has been finally estimated. All expenditure elasticities are positive, corresponding the highest value to spirits. Own price elasticities are negative and also in this case the spirits exhibit the highest value. Socio‐economic variables also play an important role in explaining consumer purchase and consumption decisions.  相似文献

Marketing is an important and challenging competitive instrument for small-scale quality food producers. Traditional commercial channels may be unprofitable and small-scale food producers often lack access to a highly concentrated retail sector. In this situation a number of strategic alliances between farmers and between farmers and other public and private actors have emerged. The aim of this paper is to discuss and compare initiatives to develop alternative marketing channels for small-scale specialty food producers. The three examples of emerging channels we investigate are (i) the 'new' farmers markets, (ii) retail initiatives where local producers deliver their produce directly to shops, and (iii) companies founded by large cooperatives to market specialty products. Recent research has justified that such initiatives can be conceptualized as hybrid governance structures, i.e. complex structures that entail properties of both market and hierarchy. We pay particular attention to the problem of quality enforcement in emerging marketing channels.  相似文献

Food consumption patterns in Asia show a trend away from staples toward high protein food derived from animal and dairy products, fruit and vegetables, fats and oils. Such changes in food consumption patterns are due to rising incomes, urbanization, globalization, and modernization of marketing infrastructure. In this article, we analyze the demand for the animal‐derived food group comprising meat (chicken, beef, pork, and mutton), eggs and fish, and derive income and price elasticities in seven Asian countries using the system‐wide approach. Demand homogeneity and Slutsky symmetry properties were tested and found to be compatible with the data. Our findings reveal that animal‐derived food as a group is a necessity (except in Taiwan) and its demand is price inelastic (except in Taiwan and Sri Lanka). The implied unconditional demand elasticities reveal that, in all countries (except beef in Japan and Taiwan), chicken, beef, pork, mutton, eggs and fish (except in Taiwan) are all necessities and the demand for all types of animal‐derived food in all seven countries are mostly price inelastic. The cross‐price elasticity estimates are mostly found to be positive, meaning that there is a higher degree of substitutability between chicken, beef, pork, mutton, eggs, and fish.  相似文献

This article offers an analytical framework for studying consumer demand for food quality based on a theory‐consistent demand model, namely, the Exact Affine Stone Index specification. Importantly, it accounts for unobserved consumer and regional heterogeneity, and allows for arbitrary Engel curves. The empirical value of our framework is illustrated in an econometric analysis of demand for food quality in China. Evaluating possible structural changes in consumer food expenditures in China is of paramount importance, given the ever‐increasing global role of China and the implications of the structural food preference changes for the global food system. The major findings emerging from this study indicate that income is an important determinant of demand for food quality and quantity with the relatively more affluent provinces having a higher affinity for food quality.  相似文献

Understanding the capacity of agricultural systems to feed the world population under climate change requires projecting future food demand. This article reviews demand modeling approaches from 10 global economic models participating in the Agricultural Model Intercomparison and Improvement Project (AgMIP). We compare food demand projections in 2050 for various regions and agricultural products under harmonized scenarios of socioeconomic development, climate change, and bioenergy expansion. In the reference scenario (SSP2), food demand increases by 59–98% between 2005 and 2050, slightly higher than the most recent FAO projection of 54% from 2005/2007. The range of results is large, in particular for animal calories (between 61% and 144%), caused by differences in demand systems specifications, and in income and price elasticities. The results are more sensitive to socioeconomic assumptions than to climate change or bioenergy scenarios. When considering a world with higher population and lower economic growth (SSP3), consumption per capita drops on average by 9% for crops and 18% for livestock. The maximum effect of climate change on calorie availability is ?6% at the global level, and the effect of biofuel production on calorie availability is even smaller.  相似文献

This paper investigates the relevance of relative prices and world income as determinants of food exports for the top trading countries in the period 1992–2012 using a panel data framework. We find that price elasticities generally take lower values for processed goods, and the opposite holds for income elasticities. Processed goods are also characterised by an inverse relationship between price elasticities and average unit values. The analysis suggests that both emerging and advanced countries can be expected to increase their export specialisation in processed goods. Furthermore, developed economies can face fierce competition from emerging countries by enhancing the quality content of their processed good exports.  相似文献

Chronic illness is a global epidemic and places significant economic and social burdens on societies. Research has shown that a healthy diet can be used to mitigate or significantly reduce the risk of many chronic illnesses. Health authorities around the world have begun regulating health claims on foods to encourage the consumption of healthy foods. However, the “ex post” efficacy of health claims regulations on consumers demand for healthy foods has not been assessed. The demand for fats and meats in Canada is estimated using a linear-approximate almost ideal demand system. The results indicate health claims decreased unhealthy food demand between 1.41% and 7.10% and increased healthy food demand between 1.95% and 8.50%.  相似文献

The role of immigration and international tourism in food product imports, as two factors which potentially influence the (trans-) formation of tastes in a country, is theoretically and empirically analysed. In using an econometric error-correction specification of an import demand function, the scale of the impact of these two factors is estimated for the case of Germany (annual data from 1967 to 1990). The results show that, while aggregate food import demand from India, Thailand, China and Turkey is inelastic with regard to migration to Germany and international travel activities of Germans to these destinations, the estimated average elasticities for imports of wine, cheese and processed/preserved vegetables from France and Italy are all well above unity, thus suggesting that immigration and international tourism may indeed affect the import demand for certain food products.  相似文献

Undernutrition and malnutrition are still problems of unacceptable proportions in many developing countries. However, the debate on the roles of income and other socio-economic variables such as women’s education and household size on food and nutrient demand continues. This study examines the demand for food and nutrients amongst households in Tanzania, using recent survey data. A quadratic almost ideal demand system (QUAIDS) is employed to estimate price and expenditure elasticities, as well as the impact of socio-economic variables on food demand patterns. A moment-based instrumental variable approach is then used to analyse the determinants of nutrient demand. The results show that income and other socio-economic variables exert significant effects on the demand for food and nutrients. The estimated expenditure elasticities for the nutrients range from 0.307 for iron to 1.26 for Vitamin B12. The elasticities are higher for those micronutrients that are consumed through animal products and lower for those micronutrients that are mainly obtained through staple foods. These results reflect the higher expenditure elasticities for meat, fish, eggs, milk, and milk products, as well as fruits and vegetables, relative to cereals and pulses, reinforcing the assertion that the demand for Vitamins A and B12, as well as calcium and zinc will increase with rising income.  相似文献

We analyse food demand patterns of Indonesian households from a resource intensity perspective and quantify the impact of changed demand patterns on the use of three major resource inputs: fossil fuel; land; and water in agricultural production. Using Indonesian Family Life Survey data, 13 major food items (which constitute 70 per cent of food expenditure) are categorised into low, moderate and high resource intensity, and income elasticity and Engel curves are estimated for the period from 1997 to 2007. Our results show that income growth in Indonesia is associated with demand patterns that are more resource intensive. By 2007, per capita requirements of fossil fuel, land and water increased by 42.7 per cent (3.13 MJ), 44.9 per cent (1.24 m2) and 50.4 per cent (2.1 kL), respectively, relative to 1997. The results imply that, at least for Indonesia, changed food demand patterns resulting from economic development will increase the demand for natural resources substantially.  相似文献

In sub-Saharan Africa, livestock is one of the key channels through which most households meet their food security needs. However, diseases such as the African Animal Trypanosomosis (AAT) constrain productivity. Using data from 445 randomly sampled small-scale cattle farmers, this paper investigates the role of integrated livestock disease control on household food security. Using a novel approach to link different food security measures to cattle productivity, the paper identifies the channels of impact at the household level. Methodologically, the paper estimated the propensity score matching algorithm to net out the effect of adoption. The results show that households who adopt RDU have record livestock productivity and higher consumption per capita expenditures. They tend to be more food secure, experience lower seasonal food supply fluctuations and experience a lower probability of falling below the food poverty line.  相似文献

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.  相似文献

The current agrarian and food crisis in the Middle East and North Africa (MENA) has been interpreted through a number of tropes. Within the dominant mainstream discourse, the MENA region is often depicted as a homogenous geographical area characterized by dryness, infertile lands and poor water resources. How did imperialism, colonialism and the Cold War influence the MENA food systems? What were the effects of trade liberalization and neoliberalism on the agricultural systems in the region? These are some questions that this paper will try to answer using a geographical and historical-comparative analysis, through a food regimes lens. Understanding contemporary social relations dynamics cannot be limited to the recent period. Agriculture and food in the MENA region are anchored in the history of power relations ruled by flows of capital and the shaping of ecological transformations during the longue durée of capitalism and its corresponding modes of control and regulation.  相似文献
