A Choice Matching Approach for Discrete Choice Analysis: An Experimental Investigation in the Laboratory
首次将选择匹配方法应用于离散选择实验，通过实验室实验比较其与标准假设性离散选择实验在偏好估计有效性和可靠性上的差异，发现选择匹配方法虽未提升有效性但能提高可靠性。
This paper is the first empirical application of the choice matching (CM) method in discrete choice experiments (DCE). An artefactual field experiment was conducted to test whether the CM applied to a DCE survey improves the validity and reliability of estimated preferences with respect to standard hypothetical DCE. Two experimental treatments were developed. In the first, subjects were exposed to the CM-based DCE; in the second, to a standard hypothetical DCE survey. Results suggest that while the CM-based DCE does not improve validity, it can increase the reliability of estimated preferences.
