A Limiting Joint-Choice Model for Discrete and Continuous Housing Characteristics
提出一个同时处理离散（卧室数量）和连续（住房质量、到市中心距离）住房特征的随机效用模型，并用旧金山租房者数据比较三种模型结构，发现放松无关选项独立性假设的模型最合适。
A simultaneous discrete and continuous random utility model for housing demand is presented. Household utility depends on three characteristics of hou sing: a discrete number of bedrooms and continuous measures of hous-i ng quality and distance to the central business district. Empirical r esults for a sample of renter households from San Francisco are compa red for a univariate structure in which each choice variable has its own utility or disutility function, a simultaneous structure assuming a discrete-continuous analog of the independence of irrelevant alter natives, and one for which this assumption is relaxed. The results in dicate that the third structure is most appropriate. Copyright 1988 by MIT Press.
