中文摘要

本文记录了劳动收入的种族差异如何可能同时解释黑人与白人个体之间的犯罪差异和财富差异。我们使用一个世代交叠模型,该模型内生决定犯罪率以及消费和储蓄决策,发现使劳动收入均等化会显著降低黑人犯罪率以及处于最低财富五分位组的黑人比例。另一方面,黑人个体更高的犯罪率和监禁率并不会显著导致其财富水平偏低。这主要是因为大多数犯罪由本已贫困且年轻的个体实施,而这些人无论如何都不会储蓄。

Abstract

This paper documents how racial differences in labor income may simultaneously explain both crime and wealth disparities between Black and White individuals. Using an overlapping generations model that endogenously determines crime rates alongside consumption and savings decisions, we find that equalizing labor incomes results in a significant decline in both the Black crime rate and the proportion of Black individuals in the lowest wealth quintile. Higher crime and incarceration rates of Black individuals, on the other hand, do not significantly contribute to their low wealth. This is primarily because most crimes are committed by already poor and young individuals who are not saving in any case.
