School Admissions Reform in Chicago and England: Comparing Mechanisms by their Vulnerability to Manipulation
研究了芝加哥和英格兰的学校招生机制改革，提出一种比较机制对操纵脆弱性的方法，发现旧机制比新机制更易被操纵，为政策变化提供支持。
In Fall 2009, Chicago authorities abandoned a school assignment mechanism midstream, citing concerns about its vulnerability to manipulation. Nonetheless, they asked thousands of applicants to re-rank schools in a new mechanism that is also manipulable. This paper introduces a method to compare mechanisms by their vulnerability to manipulation. Our methodology formalizes how the old mechanism is at least as manipulable as any other plausible mechanism, including the new one. A number of similar transitions took place in England after the widely popular Boston mechanism was ruled illegal in 2007. Our approach provides support for these and other recent policy changes.
