Generating Market Elasticity Estimates Using Cross-Sectional First-Choice and Second-Choice Data
提出一种利用消费者首选和次选信息估计交叉弹性与自身弹性比率的方法，并结合贝叶斯技术整合先验知识，生成反映决策者先验和客户偏好数据的弹性估计。
Abstract This article develops a method for using first-choice/second-choice information to estimate the ratio of cross-elasticities to own-elasticities. I then use Bayesian techniques to couple this information with prior knowledge of the elasticities. This leads to elasticity estimates reflecting the decision maker's prior knowledge as well as existing data on customer first-choice/second-choice preferences.
