Accounting for preference seperability in stated choice experiments

该项目旨在将三个不同的应用经济研究流统一到一个框架中，以便为需求预测和分析制定一个微观经济一致的框架。预测需求以改善产品性能或政策影响，需要现实地展示人类实际是如何做出选择的。将偏好可分离性理论与活动和时间使用建模以及既定选择技术的最新发展相结合，该项目计划开发对消费者均衡的新见解，以及测试偏好可分离性假设的新计量经济学方法。项目成果将导致对消费者行为以及需求预测的更好理解，并有利于涉及效益成本比较必要性的研究。

This project aims to unite three separate streams of applied economic research into a single framework in order to develop a micro-economically consistent framework for demand forecasting and analysis. Forecasting demand to improve product performance or policy impacts requires realistic representations of how humans actually make choices. Combining theories of preference separability with recent developments in both activity and time use modelling and stated choice techniques, the project plans to develop new insights into consumer equilibrium as well as new econometric methods to test for the assumption of preference separability. Project outcomes would lead to an improved understanding of consumer behaviour as well as demand forecasting, with benefits to studies involving the need for benefit cost comparisons.
