Equality and responsibility: ex ante and ex post redistribution mechanisms
研究在个人责任和环境特征决定税前收入的情况下，区分事前与事后的补偿与奖励原则，并基于这些公理刻画了五种已知和两种新的再分配机制。
Abstract We study redistribution in a setting where individual responsibility and circumstance characteristics determine pre-tax income. We distinguish between ex ante and ex post versions of the key principles of compensation and reward. Furthermore, we distinguish between absolute and relative versions of reward. On the basis of these axioms, we provide characterizations of five familiar and two new redistribution mechanisms.
