Testing the Stability of Preferences: A Nonparametric Approach
提出一种非参数方法检验偏好稳定性，利用无差异曲线凸性等理论限制，通过最小化消费量变化来检测偏好的微小变动，并应用于肉类消费数据。
Abstract A test for preference stability is developed that strengthens existing nonparametric procedures. The test uses indifference curve convexity to restrict (unobservable) compensated consumption bundles. Adding up, noninferiority, and the Slutsky equation are used to limit the range of these compensated consumption bundles. A program is proposed that simultaneously measures the changes in consumption quantities satisfying the theoretical restrictions and the expenditure elasticities minimizing the required changes. The program is applied to meat consumption data and is shown to be capable of detecting small changes in preference.
