Hedonic Estimation of Quality Factors Affecting the Farm‐Retail Margin
用加州鲜桃的产销价格数据，检验了季节内时间和质量特征如何影响农场到零售的价差，发现价差随季节递减、随质量提升而扩大，对生产者有定价启示。
Abstract A model of the farm‐retail marketing margin is tested using producer and retail prices of a perishable product in which time during season and quality characteristics are variable. Empirical analysis verifies that the marketing margin of California fresh peaches decreases during the season and increases with improved quality. Results identify potential producer gains from improving product quality early in the season, and from price signals compensating producers for quality characteristics other than weight.
