As measured by Gini coefficients, fractile inequalities, and tail power laws, wealth is distributed less equally across people than are labor earnings. We study how luck, attitudes that shape saving decisions, and growth rates of labor earnings balance each other in ways that simultaneously shape joint distributions across people of labor earnings, age, and wealth together with an equilibrium rate of return on savings that plays a pivotal role in balancing contending forces. Strong motives for people to save and for firms to demand capital raise an equilibrium interest rate enough to make wealth grow faster than labor earnings. That makes cross-sectional wealth more unevenly distributed and have a fatter tail than labor earnings, as in US data.

收入增长和财富分配[经济科学]

根据基尼系数,分数不等式和尾幂定律来衡量,财富在人与人之间的分配不均比在劳动收入上的分配不均。我们研究运气,决定储蓄决定的态度以及劳动收入的增长如何以同时塑造劳动收入,年龄和财富的人的共同分布以及均衡的储蓄回报率如何相互平衡的方式相互平衡。在平衡竞争力量中的作用。人们储蓄的强烈动机和企业要求资本的强烈动机提高了均衡利率,足以使财富的增长快于劳动收入的增长。如美国数据所示,这使得横截面财富的分配更加不均匀,尾巴比劳动收入更丰厚。
