Preference Variable Impacts in Direct and Inverse Differential Demand Systems
基于Tintner-Ichimura-Basmann关系，在逆Rotterdam模型中引入偏好变量，通过限制偏好变量对边际效用的影响减少参数空间，并用于分析产品质量对新鲜柑橘需求的影响。
Abstract Preference variables are included in the inverse Rotterdam model based on the Tintner‐Ichimura‐Basmann relationship linking preference effects on quantities demanded to price effects and preference effects on marginal utilities. Restrictions are placed on the effects of the preference variables on the marginal utilities, resulting in reductions in the parameter space for the preference variables in both direct and inverse demand systems. The model is used to analyze impacts of product quality on fresh citrus demand.
