先前的研究依赖于父亲收入的短期平均值，估计收入的代际弹性（IGE）约为0.4。由于持续的短暂波动，这些估计数被调低了大约30%或更多。根据包含父母和子女收入历史的行政数据，IGE估计在0.6左右。这表明美国的流动性比之前的研究表明的要低得多。对于很少或没有财富的家庭，代际流动性的估计值要低得多，这为预测借贷限制造成的差异的理论模型提供了实证支持。
Previous studies, relying on short-term averages of fathers' earnings, have estimated the intergenerational elasticity (IGE) in earnings to be approximately 0.4. Due to persistent transitory fluctuations, these estimates have been biased down by approximately 30% or more. Using administrative data containing the earnings histories of parents and children,, the IGE is estimated to be around 0.6. This suggests that the United States is substantially less mobile than previous research indicated. Estimates of intergenerational mobility arc significantly lower for families with little or no wealth, offering empirical support for theoretical models that predict differences due to borrowing constraints.
