Pre‐committed consumption represents the portion of demand that is determined by non‐price and non‐income factors. This study uses quarterly data to estimate a Generalised Almost Ideal Demand System (GAIDS) to test for the existence of pre‐committed meat consumption in Australia. Two specifications are estimated to evaluate the impact of seasonal and time trend factors on pre‐committed demand. Evidence is found for the existence of pre‐committed chicken consumption when jointly estimated with seasonal and time trend factors. Results support improved demand modelling of Australian meat consumption using the GAIDS and provide insights into how Australian meat demand is affected by price, expenditures, pre‐committed consumption, seasonality, and trends.  相似文献

The wine market has evolved dramatically over the last three decades. The premium wine segment has expanded significantly to the detriment of basic wines. Nevertheless, in traditional wine producing and consuming countries, inexpensive wines still account for a large market share, both in volume and value. Marketing strategies for such wines are changing in an attempt to tap this increasingly crowded market segment. Despite its importance, the basic wine segment has not been studied in‐depth and is often assumed to have no product differentiation. This paper tried to ascertain the existence of a possible degree of heterogeneity within nonpremium wines and to measure, by means of elasticity computation, the relationships among categories of wines aggregated with criteria that go beyond price. A demand system (censored QUAIDS) was estimated, using a statistically representative panel of 6,773 Italian households, to see to what extent, if any, substitution occurs in home consumption of basic wines, which is the main channel of distribution of inexpensive wines in Italy. Although price is an important lever in supply policies, our results also suggest the importance of packaging, such as carton as an alternative to glass.  相似文献

Demand for organic and conventional vegetables is investigated using data from A.C. Nielsen’s 2006 Homescan panel. We use a Bayesian Markov chain Monte Carlo technique, along with data augmentation, to estimate a large linear approximate Almost Ideal Demand System with censored dependent variables. Demands are price elastic, and expenditure elasticities are very high for organic vegetables, whilst demands for conventional vegetables are primarily inelastic. We find a mix of gross substitution and complementarity among the vegetable products, but net substitution is the dominant pattern. Socio‐demographic characteristics also play important roles in demands. These findings can inform deliberations about marketing campaigns, nutrition education and policy interventions.  相似文献

There is renewed interest in robust estimates of food demand elasticities at a disaggregated level not only to analyse the impact of changing food preferences on the agricultural sector, but also to establish the likely impact of pricing incentives on households. Using data drawn from two national Household Expenditure Surveys covering the periods 1998/1999 and 2003/2004, and adopting an Almost Ideal Demand System approach that addresses the zero observations problem, this paper estimates a food demand system for 15 food categories for Australia. The categories cover the standard food items that Australian households demand routinely. Own‐price, cross‐price and expenditure elasticity estimates of the Marshallian and Hicksian types have been derived for all categories. The parameter estimates obtained in this study represent the first integrated set of food demand elasticities based on a highly disaggregated food demand system for Australia, and all accord with economic intuition.  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

We present empirical evidence on how changes in food preferences have contributed to nutrition transition, where the dietary pattern of households shifts away from traditional staples. Using household-level time series cross-section survey data for India, we estimate time varying demand elasticities, revealing evidence of the declining importance of cereals in Indian household diets. The estimates show that Indian demand for cereals has become more income inelastic and price elastic. We also find that cereals are a substitute rather than a complement to animal products in household diets. Since changes in elasticities can only be attributed to variation in utility parameters, this indicates that cereals are losing favour with Indian households. These findings have implications for Indian food policy design and implementation.  相似文献

Research has examined consumers’ attitudes toward ecolabels, but there is a lack of research examining whether niche ecolabels give a competitive advantage in consumer markets. The authors aim to fill this gap by exploring the four conditions of market success (evidence of price premiums, market share, access to retailers, and elasticities) established in the literature. Three varieties of MSC-certified fish are studied. Differences are observed across the three varieties that lead to the following conclusions: MSC-labeled products do not systematically sell at a premium; price has an inelastic effect on the demand of certified national brands, but increased distribution has a very elastic effect on demand; and MSC-labeled products do not experience seasonal effects. The consumer market is responding favorably to the label, but ecolabeled fish is in an introductory stage. Price premiums vary; the retailer’s brand is playing a prominent role.  相似文献

The effect of a Chinese minimum wage increase on China's textile market as well as on the world cotton market is evaluated. Based on a Nonlinear Quadratic Almost Ideal Demand System (NQAIDS) model of China's textile demand, the results suggest that the income elasticity for textiles is around 0.6 in China, and that apparel is less price responsive than home textiles and other textile products. Simulation results suggest that a minimum wage increase would raise Chinese domestic textile consumption and lower Chinese textile exports. Most of the decline in textile exports by China is offset by expansion in other countries’ domestic textile production and results in a slight increase in world cotton mill utilization and higher clothing prices.  相似文献

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.  相似文献

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 main objective of this article is to examine econometric estimates of price elasticities of food trade functions. We investigate the relevance of the prominent gravity approach. This approach is based on the assumptions of symmetric, monotone, homothetic, Constant Elasticity of Substitution (CES) preferences. We test all these assumptions using intra‐European trade in cheese. In general, the assumptions made on preferences by the gravity approach are not supported by our dataset. The bias induced in the estimated price elasticities is ambiguous.  相似文献

This Address considers a range of issues relating to the contribution of meat consumption and livestock production to global warming, given the need highlighted by the Committee on Climate Change (CCC) to reduce global GHG emissions by over 50% by 2050. The IPCC Climate Change 2014 report recognised that demand oriented measures may also contribute to GHG mitigation. The paper reviews a number of studies which examine demand‐led mitigation potentials, and concludes that such estimates ignore the market effects of changes in meat consumption habits or demand oriented policies. A simple partial equilibrium model of beef, poultry, pig and ovine meats is developed for the major regions of the world to explore the impact of a range of scenarios which might reduce meat consumption and GHG emissions. These include emissions taxation, long‐term trends in reduction of red meat consumption in developed economy regions, and supply side improvements in livestock emissions intensities. The paper discusses problems associated with many published demand elasticities suitable for incorporation into a market model, problems of selection from widely varying published estimates and their appropriateness for longer‐run projections. The dearth of published supply elasticity estimates is also highlighted. The modelling concludes that economic and population growth to 2050 without any mitigation measures will lead to a 21% increase in per capita meat consumption and a 63% increase in total consumption and GHG emissions by 2050. However, the mitigation projections from the scenarios explored only generate a 14% reduction in cumulative emissions from the baseline 2050 projections, insufficient to meet the CCC target.  相似文献

There is an increasing policy interest in pesticide taxation schemes as a measure to reduce harmful effects of pesticide use. The effectiveness of such tax depends, however, on the price elasticity of demand for pesticides. Moreover, information on these demand elasticities and their determinants is of crucial relevance for policy‐making and normative modeling approaches. In this article, we present a meta‐analysis based on studies that have estimated pesticide demand elasticities in Europe and North America. Our meta‐analysis reveals that the own‐price elasticities of demand for pesticides are, with a median of ?0.28, significantly smaller than zero, but also significantly larger than ?1, i.e. to be inelastic. We find that the demand for pesticides for special crops is less elastic than that for arable and grassland. In addition, the demand for herbicides is more elastic than for other pesticides. Studies that consider only short‐term horizons and little flexibility for farmers to adjust to price changes generate significantly less elastic pesticide demands. The results also indicate that more recent studies identify lower pesticide price elasticities of demand. Furthermore, we find that peer‐reviewed studies tend to find more inelastic results compared to grey literature.  相似文献

The primary purpose of this paper is to analyse the short-run price responsiveness of wastepaper demand in Sweden for four different paper and board products, as well as any structural changes in demand behaviour for these products over time. The analysis is done within a variable Translog cost function model, and we employ data for individual paper and board mills over the time period 1974-1994. The results suggest that the short-run own-price sensitivity of waste paper demand is relatively high compared to those of other input factors, and it has also tended to increase over time for some of the paper products. In addition, wastepaper demand has also become more sensitive to changes in energy prices, and its use increases with increases in the price of energy. However, the relationship between wastepaper and woodpulp is more complex, and in many instances wastepaper and woodpulp are short-run complements. Overall this implies that price based recycling policies will be relatively successful in promoting wastepaper use, but they will not necessarily lead to the conservation of virgin forest resources.  相似文献
