The Demand for Organic and Conventional Produce in London, UK: A System Approach
研究了伦敦家庭对有机和常规水果蔬菜的实际购买数据，发现有机产品价格弹性更高，且低收入有孩家庭对价格最敏感，同时消费者对有机产品有较强忠诚度。
Abstract 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.
