Estimates of intergenerational mobility in lifetime income derived from incomplete income histories routinely incorporate in the estimation process, necessary life-cycle adjustments to annual income data. The two-stage method presented here first estimates proxies for fathers’ and sons’ lifetime family incomes from annual income observations, schooling and race; and then uses these income proxies to derive mobility measures. Applying this to United States PSID data for sons born between 1952 and 1981, we find a decline in intergenerational mobility in lifetime family income, as measured by the intergenerational elasticity of income, the rank-rank correlation, absolute upward mobility, and other indicators.

终生收入的代际流动

来自不完整收入历史的终生收入的代际流动性估计通常包含在估计过程中，对年收入数据进行必要的生命周期调整。这里介绍的两阶段方法首先根据年收入观察、教育和种族来估计父亲和儿子一生的家庭收入；然后使用这些收入代理得出流动性措施。将此应用于美国 1952 年至 1981 年间出生的儿子的 PSID 数据，我们发现终生家庭收入的代际流动性下降，这是通过收入的代际弹性、等级相关性、绝对向上流动性和其他指标来衡量的。
