The demand for meat and fish in Spain: Urban and rural areas

The aim of the paper is to explain to what extent meat consumption patterns in Spain are different in rural and urban areas and which are the factors explaining differences and similarities. A demand system using cross-section data from the latest Spanish National Survey has been estimated. Unit values have been used instead of market prices and price and quality effects have been obtained. The main conclusion is that meat consumption patterns in urban and rural areas are not really different as regards economic factors. Some small income and price effect differences have been found, specially for fresh pork and fish, Responses to changes in income and price are higher for fresh pork consumption in rural areas and for fish in urban areas.     

Demand for milk quantity and safety in urban China: evidence from Beijing and Harbin

Urban households account for most of the milk consumption in China, but their consumption is hampered by safety concerns. Using survey data collected in Beijing and Harbin in 2010, this paper simultaneously analyses urban households' milk consumption using a multiple linear model and their willingness‐to‐pay for milk safety using an ordered choice model. The results of this study show that as income increases, urban households consume more milk and are willing to pay a higher premium for milk safety. Modern food marketing channels play a positive role in stimulating milk consumption and building consumers' confidence in milk safety. The growth in the elderly population influences milk consumption positively, but their demand for milk safety is negatively affected by higher price. The combined analysis of households' demand for milk quantity and safety may be useful to the Chinese government in promoting the development of the domestic milk industry and to dairy firms in exploring the milk market in China.     

Demand for dairy products in Mexico

Mexico is the world's largest importer of non-fat dry milk (NFDM) and imports of cheese, fluid milk, and whey have increased rapidly in the past four years. In the wake of GATT and the NAFTA, as well as recent economic developments in Mexico, world dairy markets will be affected as a result of changes in the Mexican dairy sector. The study analyzes both domestic and import demand for dairy products in Mexico to determine price and income elasticities as well as import elasticities. The results indicate that the demand for fluid milk is the most responsive to price changes and NFDM demand is inelastic with respect to its own price. There is little subtitution between fluid milk and non-fat dry milk, although fluid milk is relatively elastic, which suggests the existence of other substitutes for fluid milk. Estimation of import demand equations reveal similar trends in response to price changes, but income elasticity of imports was highest for fluid milk which suggests that Mexico will import possibly more fluid than dry milk as incomes rise. The exchange rate was the most significant variable influencing all dairy product imports.     

大城市居民低温奶产品消费及其影响因素分析以北京市为例

目的 低温奶产品是我国唯一可以与国际奶产品相抗衡的产品品类,未来低温奶产品必然在我国形成新的消费趋势,并成为复兴民族乳业的关键。基于此,探究大城市居民的低温奶产品消费认知水平、消费现状及其消费的影响因素既可开拓国内低温奶产品消费市场,也可弥补该产品消费研究的不足,对提高我国奶业国际竞争力具有重要现实意义。方法 文章通过使用2019年北京市8个辖区内的418位城镇居民乳制品消费调研数据,以不同群体特征作为切入点,深度分析大城市居民低温奶产品消费认知水平及消费现状,并借助Heckman两阶段模型考察个人及家庭特征和产品认知信息是否是影响城镇居民低温奶产品消费行为决策和消费水平的主要因素。结果 学生人口数、工作人口数、收入水平以及年龄、职业因素分别影响居民巴氏杀菌奶和低温酸奶的消费行为决策。年龄、教育水平以及性别、人口总数、职业因素分别影响居民巴氏杀菌奶和低温酸奶的消费水平。营养价值、口感风味和制作工艺因素对居民巴氏杀菌奶消费行为决策和消费水平均有显著影响,而保质期和价格因素仅对消费行为决策有显著影响。口感风味、制作工艺和价格因素对居民低温酸奶消费行为决策影响显著,但只有口感风味因素对消费水平有显著影响。结论 城镇居民低温奶产品认知概念薄弱,对营养价值、口感风味和保质期信息的认知程度较高。低温奶产品消费具有区域性差异,消费主力集中在女性人群、40~50岁人群、高学历和高收入人群中。个人和家庭特征以及产品认知信息对城镇居民巴氏杀菌奶和低温酸奶的消费行为决策和消费水平均具有显著影响。未来我国大城市居民的乳制品消费将逐渐趋于新鲜化和休闲化发展,低温奶产品消费将发展为新兴消费趋势,液态奶产品消费结构逐步改善。     

Pseudo panel data estimation technique and rational addiction model: an analysis of cigarette,alcohol and coffee demands

We use a pseudo‐panel data approach to analyze the relationship between the consumptions of cigarettes, alcohol, and coffee in a rational addiction framework. We find that while cigarette and coffee demands fit well with the rational addiction model, alcohol demand conforms to a model with inventory effects. The results suggest that alcohol consumption increases the marginal utility derived from consumption of cigarettes. Increasing alcohol prices would decrease not only the consumption of alcohol, but also the consumption of cigarettes. On the other hand, increasing cigarette prices do not have the same effect on consumption of alcohol. The cross‐price elasticity of coffee with respect to cigarette price is positive and significant which suggests that coffee substitutes for cigarettes when cigarette prices increase. The cross‐price elasticity of alcohol with respect to coffee price is found to be negative and significant. On the other hand, Morishima elasticities of substitution indicate that cigarette, alcohol and coffee substitute each other along the indifference curve when relative prices change.     

Imports versus Domestic Production: A Demand System Analysis of the U.S. Red Wine Market

The U.S. wine market experienced rapid growth in all facets—production, consumption, exports, and imports—over the past decade. Red wine imports more than tripled while consumption of domestically produced red wines doubled. This research estimates demand elasticities of U.S. red wine imports from five countries accounting for over 90% of imports—Italy, France, Spain, Australia, and Chile—using the first-difference version of the almost ideal demand system (AIDS). These elasticities are compared with those for domestically produced red wine. Results for conditional expenditure elasticities indicate that the U.S. red wine industry gains over imports when U.S. consumers' total expenditures on red wine increase. However, comparing own- and cross-price elasticities reveals an increase in the price of U.S. red wine results in a decline in quantity demanded six times greater than for French and Italian red wines and over 20 times greater than other import countries, thus harming the U.S. red wine industry. Empirical results suggest that U.S. red-wine producers could increase their total revenue by decreasing prices, while Italian and French producers can increase total revenues by increasing them.     

Demand,challenges, and marketing strategies in the retail promotion of local brand milk

This article addresses the demand and challenges for local brand milk and focuses on the marketing strategies for retail promotion. While federal and state government make efforts to promote local food purchases and consumption at the farm level, local foods face significant distribution challenges in grocers, especially in larger retail stores. Limited shelf space and high pricing by retailers impedes consumers’ purchases and results in weak competitiveness for local brands. Therefore, it is essential for local producers and “buy local” programs to understand what types of promotion and marketing strategies might be more effective in stimulating demand in retail outlets. Using 2010-2011 Nielsen Retail Scanner data in the Northeast region, we estimate a random-coefficient discrete choice model of demand to determine the effects of nutritional characteristics, price, packaging, and distribution strategies on the consumers’ choice to purchase locally branded milk. Results show that local brand milk faces significant demand challenges in addition to high prices and limited outlets in competing with lower-priced products. Marketing strategies, such as price cut, one-gallon package offering, and expanded presence in retail stores, can significantly stimulate the demand for locally branded milk, with one-gallon package offering being the most effective strategy.     

辽宁农业灌溉用水影响因素时空差异性研究

目的 文章基于2000—2019年辽宁农业灌溉用水相关数据,将农业灌溉用水压力、效率、用水价格、种植结构等因素纳入农业灌溉用水需求模型,估计各影响因素对农业灌溉用水需求的影响,更好地保障粮食和水资源安全。方法 利用时空地理加权回归模型研究辽宁各地级市农业灌溉用水影响因素作用的时空差异性。结果 （1）不考虑影响因素作用的时空差异性,用水价格和农村居民人均收入变动对辽宁农业灌溉用水需求的影响特别小。（2）考虑到影响因素作用的时空差异性,除了朝阳和大连,其余各地级市农业灌溉用水需求的价格弹性在2014年前后呈现出负向增大的态势,水价改革还有较大的效力空间。（3）辽宁农业灌溉用水效率和种植结构的回归系数在空间上呈现出中部低,四周高的特点。（4）城镇化程度对农业灌溉用水需求的影响呈现出由东北向西南逐渐递减,由正向较强逐渐向负向较强的演变。结论 依据辽宁农业灌溉用水的各影响因素的作用强度,种植结构、用水效率和城镇化程度是影响辽宁农业灌溉用水需求的主要因素,合理制定城镇化规划对该因素回归系数呈显著上升趋势的地级市尤为重要。     

新一轮国际粮食价格上涨：原因及对中国市场的影响

[目的]随着中国粮食进口不断增加,国内外市场联系越来越紧密。2020年下半年以来,国际市场粮食价格快速上涨,对国内粮食市场产生一定影响,分析国际市场价格上涨的原因和影响对确保国内粮食供应稳定、保障国家粮食安全具有重要意义。[方法]文章分析了2019年以来小麦、大米、玉米、大豆4种粮食产品的国内外价格走势,从供需状况、贸易政策、气候变化等因素分析国际市场价格波动的原因,并探讨了国际价格对国内价格的影响。[结果]当前全球主要粮食品种供应充足,库存仍处于较高水平,此轮国际粮食价格上涨主要是受到美国等发达国家宽松的货币政策以及疫情后全球消费逐步回暖的影响;但国际市场价格上涨对中国市场的影响总体有限,国内小麦、大米、玉米价格上涨的主因是国内消费回暖和生猪产能恢复带动的饲用需求快速增长,油用大豆受国际市场的影响较大。[结论]为稳定国内粮食市场,避免国际市场的冲击,中国要进一步提升粮食综合生产能力,强化科技支撑,加强粮食储备管理,健全政策支持体系,并引导居民建立科学的消费观念。     

Household size and residential water demand: an empirical approach*

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.     

Asymmetric price transmission in the Spanish lamb sector

This article investigates the non-linear adjustment betweenfarm and retail prices in the lamb sector in Spain, using athree-regime Threshold Autoregressive Model. The results indicatethat, in the long run, price transmission is perfect and anysupply or demand shocks are fully transmitted along the marketingchain. In the short run, price adjustments between the farmand the retail levels are asymmetric and reveal a demand-pulltransmission mechanism. On the other hand, retailers benefitfrom any shock, whether positive or negative, that affects supplyor demand conditions.     

最低收购价政策调整对我国粮食安全的影响以稻谷为例

[目的]最低收购价政策实施以来,在稳粮价、促生产、保粮安的同时,也产生了显著的负面影响,探索以市场机制为核心的粮食价格支持政策改革势在必行。[方法]文章以稻谷为例,通过构建局部均衡模型,模拟逐渐下调最低收购价、取消最低收购价、取消最低收购价并大幅增加农业补贴等方案对我国稻谷的产量、总消费、库存和净进口等方面的影响,进而探究最低收购价政策调整对我国粮食安全的影响。[结果]（1）下调稻谷最低收购价,对稻谷市场价格、总产量和总消费的影响较小,而对库存和净进口量的影响较大;（2）取消最低收购价,虽然能大幅度减小国内外差价、库存量和进口量,但短期内也会显著减少稻谷产量,对我国的粮食供给安全带来了巨大冲击;（3）取消稻谷最低收购价,并大幅度提高了农业补贴后,稻谷总产量下降水平明显减少,既解决了托市收购带来的负面影响,也降低了取消托市收购对粮食供给安全的冲击。[结论]最低收购价政策的支持效应显著,为充分保障国内粮食安全,在推行粮食市场化改革时,应首先考虑小幅度下调最低收购价,而不是一次性取消最低收购价政策;同时,要配套相应的补贴政策,优化农业补贴结构,来保障粮农的种植积极性。     

The distributional effect of a large rice price increase on welfare and poverty in Bangladesh

This paper studies the distributional effect of a sharp rice price increase on welfare and poverty in Bangladesh. We employ household consumption data and include the indirect effect of price responses to estimate the welfare loss. Our findings suggest that the estimated welfare effect can be misleading if household responses to rice consumption and production are ignored. This study further supports the hypothesis that the poor are the main victims of such a shock. Our examination also indicates that a higher rice price may increase or decrease the poverty head‐count ratio, depending on the choice of the poverty line, but worsens the country's poverty situation when it is measured by the per capita consumption gap. Our analysis reveals that the government can play a central role to prevent and mitigate such shocks, particularly in the medium to long run. On the methodological side, we observe that consumption provides a more consistent outcome across different methods of analysis than household income.     

Adaptive management decision of agroforestry under timber price risk

In an effort to increase wood production and mitigate environmental problems, agro-forestry practices have emerged as a viable strategy in the Northern Plains of China, where one popular form of the agro-forestry system consists of fast-growing and high-yield plantation of poplar (populus) trees and the underwood planting of button mushroom (Agaricus bisporous). This paper examines adaptive management decision-making with stochastic dynamic programming under risk of timber price. Under the assumption of risk neutral preferences of the investors, the results suggest that the reservation price strategy remains optimal for the harvesting decision of agro-forests: when the timber price is higher than the reservation price, poplar trees should be harvested to end agro-forestry; otherwise, the trees should be retained. Numerical results are presented for sample agro-forest stands, which show that, with underwood planting, the reservation price for timber harvesting will be higher than that in pure forest.     

Abolition of Raw Milk Quota in the European Union: A CGE Analysis at the Member Country Level

This paper discusses a generic approach to implementing production quotas in an applied general equilibrium framework. The quota rent is interpreted as additional primary factor payments. We analyse the abolition of the raw milk quota and the elimination of export subsidies for dairy products in the European Union at a member country level. The raw milk output increases in Denmark, Ireland, Italy, Luxembourg, the Netherlands and Spain, while it declines in Germany, Greece, Portugal and Sweden. The EU‐wide effect for raw milk production is an output increase of 3% and a price decline of 22%. To assess the robustness of the critical assumption about the raw milk quota rent we apply Arndt and Pearson's Systematic Sensitivity Analysis.     

Disaggregated econometric estimation of consumer demand response by alcoholic beverage types

The paper presents estimates of price elasticities of demand for 12 disaggregated alcoholic beverages in Australia: premium beer, full strength beer, low alcohol beer and mid‐strength beer; red bottled wine, white bottled wine, sparkling wine, cask wine; dark and light ready‐to‐drink (RTD); and dark and light spirits. These disaggregated categories correspond closely to the commodities of interest to public policymakers with respect to taxation and health policies. The system of demand equations is estimated with Nielsen's data using a semiflexible Almost Ideal Demand System model in order to impose negative semi‐definiteness on the demand parameters. Results indicate elastic own‐price elasticities for virtually all commodities. Cross‐price elasticities suggest that beverages most linked with negative externalities, namely full strength beer, dark RTD and dark spirits, may need to be taxed jointly. Any proposed tax increase to cask wine may also result in consumers shifting demand to more undesirable beverages. The elasticity estimates are used to illustrate the effect of a hypothetical change towards taxation equalisation based on alcohol content. These elasticities offer crucially needed inputs for analysing any tax change policies.     

Product Labeling and Economic Value of Milk Market Segmentation

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.     

中国储备棉轮入轮出机制对棉花市场传递效应研究

文章以1978-2016年中国棉花价格、消费产量及轮入轮出数据为基础,采用联立方程模型,就储备棉轮入轮出机制对棉花供需的传递效应进行实证分析。研究表明,中国棉花储备政策及轮入轮出机制对于平衡国内棉花市场供求、防止棉花价格过度波动起到积极的作用。储备棉轮入轮出机制对国内棉花产量、消费量的传递效应显著且存在一定差异,对国内棉花产量的传递效果要强于对国内棉花消费量的传递效应,产生这种差异的主要原因在于储备棉轮入轮出机制的传递路径有所不同。应坚持和完善储备棉轮入轮出机制,提升储备棉轮入轮出机制对棉花需求的调控作用,实现储备棉轮入轮出机制常态化,通过明确储备棉轮入轮出机制的政策目标和市场定位,加强棉花市场信息系统建设,使储备棉轮入轮出机制成为我国棉花支持政策体系的主要手段。     

Agricultural Trade among NAFTA Countries: A Case Study of U.S. Meat Exports

The U.S. NAFTA partners are important markets for U.S. meat exports. A source-differentiated almost ideal demand system is used in this study to estimate meat demand in Canada and Mexico. Empirical results suggest that while a U.S. price increase in the Canadian market is expected to increase U.S. sales revenues; it would decrease sales revenues in the Mexican market. Furthermore, an increase in meat expenditures in Canada and Mexico is expected to increase the demand for U.S. meats, while the bovine spongiform encephalopathy outbreaks have had a negative effect on U.S. and Canadian beef market shares. Finally, a decomposition of the causes of changes in demand for U.S. meats over time is performed.     

Vietnamese Consumers’ Willingness to Pay for Safe Pork in Hanoi

Abstract

Food safety is one of the main concerns and the biggest challenge for consumers due to its direct influence on human health. In order to deal with unsafe food situation, the demand for food hygiene has increased in recent years as well as the consequent increase in price accepted by consumers. This study aimed to estimate consumers’ willingness to pay (WTP) and to examine the determining factors influencing their WTP for safe pork using double-bounded dichotomous choice contingent valuation method (DBDC CVM). The data were collected from a survey with a sample size of 134 respondents in Hanoi, Vietnam using two sets of questionnaires on the consumption of rib and shoulder of pork. The results revealed that the percentages of the consumers willing to pay a premium for more hygiene shoulder and rib of pork were 81.75% and 73.01%, respectively. The mean WTP was 129,000 VND (US$6.07) for both safe shoulder and rib, 48.7% and 37.8% higher than the regular market price, respectively. The results showed that consumers’ awareness of the risk of unhealthy pork, household income and expenditure were the positive determinants to WTP; meanwhile, the amount of pork consumption per month negatively affected the willingness to pay more for shoulder and rib of pork.
