"We use two sample instrumental variables to estimate intergenerational economic mobility from 1940 to 2000. We find intergenerational mobility increased from 1940 to 1980 but declined sharply thereafter, a pattern similar to cross-sectional inequality trends. However, the returns to education...

We use a two-sample instrumental variables approach to estimate a time series of intergenerational economic mobility using the decennial U.S. Censuses. We find that the intergenerational income elasticity (IGE) followed a roughly U-shaped pattern from 1940 to 2000 that is similar to well known...

"Solon's (1992) landmark study estimated the intergenerational elasticity (IGE) in income between fathers and sons to be 0.4 or higher. This dramatically changed the consensus view of the U.S. as a highly mobile society. In this comment, I show both analytically and empirically how Solon and...
