差别待遇政策——如优惠待遇、平权行动和性别平等政策——在什么情况下是出于效率考虑而合理的？我提出了一个非参数分配模型，在这个模型中，决策者根据代理人的特征和有关其类型的噪声信息，将代理人分配到不同的待遇或位置，以最大化总盈余。我提供了主体信号结构的充分必要条件，表征盈余最大化是否需要差别待遇，并研究了信号结构的偏差和信息性如何决定差别待遇的效率含义。我研究了这个模型对不平等、权力下放和实证工作的影响。（jel d63, d82, d83, i23, i24, j71）
When are differential treatment policies—such as preferential treatment, affirmative action, and gender equity policies—justified by efficiency concerns? I propose a nonparametric assignment model where a policymaker assigns agents to different treatments or positions to maximize total surplus, based on the agents’ characteristics and noisy information about their types. I provide necessary and sufficient conditions on the agents’ signal structures, which characterize whether surplus maximization requires differential treatment or not, and study how the bias and informativeness of signal structures determine the efficiency implications of differential treatment. I examine implications of this model for inequality, decentralization, and empirical work. (JEL D63, D82, D83, I23, I24, J71)
