Explaining the Choice of Organic Produce: Cosmetic Defects, Prices, and Consumer Preferences
使用双方程probit模型，基于店内收集的外观瑕疵、价格及消费者特征数据，分析影响有机农产品购买概率的因素，发现商店选择、价格敏感度、家庭有无18岁以下子女及教育程度有显著作用。
Abstract The choice between organic and conventional produce was estimated empirically using a two‐equation probit model. Data were collected in‐store on cosmetic defects, produce prices, and consumers' demographic and economic traits. Store choice displayed a significant impact on the probability of purchasing organic produce. Shoppers at the specialty grocer were sensitive to price differences between organic and conventional items. Households with children under eighteen were more likely to purchase organic produce while shoppers with graduate or professional degrees were less likely to do so. Differences in cosmetic defects had statistically significant albeit small effects on the probability of purchasing organics.
