Theoreticall and experimental investigation of school choice mechanisms

对于择校机制，进行了理论分析和实验室实验。首先，从理论上考察了给予少数民族学生配额的平权行动政策的后果，并在实验室对其预测进行了检验。其次，考察了东京的择校机制，并与美国的其他择校机制进行了实验比较。在这两个实验中，尽管每个机制的匹配结果与理论预测大体一致，但不可忽视的数量的学生歪曲了他们对学校的真实偏好。因此，可以观察到，在实现匹配的过程中，有很多学生嫉妒其他学生。这些成果已经在几个国际会议上发表，现在正在准备提交给学术期刊。

As for school choice mechanism, theoretical analysis and laboratory experiments were conducted. First of all, consequence of affirmative action policy that gives quota for minority students was theoretically investigated, and its prediction was examined in the laboratory. Second, school choice mechanism adopted in Tokyo was investigated, and then experimental comparisons with other mechanisms adopted in the United States were done. In both experiments, though matching outcome of each mechanism generally consistent with theoretical predictions, non-ignorable number of students misrepresented their true preferences over schools. As a consequence, it was observed that in realized matching, there were a lot of students who had envy for other students. These results were presented at several international conferences, and now submission to academic journal is preparing.
