College Admission with Multidimensional Privileges: The Brazilian Affirmative Action Case
研究了巴西2012年强制公立大学对种族和低收入群体实施平权政策后，学生策略性申报特权导致的不公平现象，并提出了公平且防策略的录取机制。
In 2012, Brazilian public universities were mandated to use affirmative action policies for candidates from racial and income minorities. We show that the policy makes the students’ affirmative action status a strategic choice and may reject high-achieving minority students while admitting low-achieving majority students. Empirical data shows evidence consistent with this type of unfairness in more than 49 percent of the programs. We propose a selection criterion and an incentive-compatible mechanism that, for a wider range of similar problems and the one in Brazil in particular, is fair and removes any gain from strategizing over the privileges claimed.
