本文研究了由个体的选择行为估计风险下选择的偏好泛函。我们注意到，个体之间和个体内部的行为存在异质性。“个体间的异质性”是指人们在偏好泛函和这些泛函的参数方面都是不同的。我们所说的“个体内的异质性”是指，对于同一个选择问题，即使是同一个人，其行为也可能不同。我们提出的方法，考虑到所有形式的异质性，特别是集中在使用混合模型来捕捉偏好泛函的异质性。(C)2009 Elsevier B.V.保留所有权利。
This paper is concerned with estimating preference functionals for choice under risk from the choice behaviour of individuals. We note that there is heterogeneity in behaviour between individuals and within individuals. By 'heterogeneity between individuals' we mean that people are different, in terms of both their preference functionals and their parameters for these functionals. By 'heterogeneity within individuals' we mean that the behaviour may be different even by the same individual for the same choice problem. We propose methods of taking into account all forms of heterogeneity, concentrating particularly on using a Mixture Model to capture the heterogeneity of preference functionals.
