Wealth Mobility
利用1966至1981年美国成年男性面板数据，发现财富分布中虽存在较强持续性，但仍有超过一半的家庭改变了财富五分位组，不过多数移动幅度较小，极端移动极为罕见。
This paper examines the wealth mobility of a panel of mature American men between 1966 and 1981. Although greater persistence exists than within the income distribution, a sizeable degree of movement within the wealth distribution is observed. Slightly more than half of the households changed quintiles. However, the magnitude of the movement was modest, with 78% of the moves to an adjacent quintile. Movements into either extreme of the wealth distribution were relatively rare. Really big moves, from the poorest to richest group, were extremely rare, with the probability of a black making such a move within fifteen years approximately zero. © 2001 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
