This paper characterizes the patterns of intergenerational mobility in the United States using data for matched parent/child pairs from the National Longitudinal Surveys. In general, what is found is far from the extremes of either perfect mobility or perfect immobility. Parents' log income explains only about 9 percent to 11 percent of the variation in children's log incomes. Earnings exhibit more mobility than does total income, and the difference is most striking for daughters. The paper also identifies the influence of family background characteristics on mobility. The addition of these background variables adds another 3 to 5 percent age points to the R2 in the intergenerational earnings and income regressions.

In the popular press and among policymakers the effect of no-fault divorce laws on divorce rates remains an issue (see e.g., New York Times, 23 July 1991). In my 1986 article in this Review, I show that the adoption of one form of no-fault divorceunilateral divorce-does not lead to a significant increase in divorce rates.' The theoretical model that is consistent with this empirical evidence would imply that the new law does not decrease the costs of divorce. It merely redefines which party has the right to terminate the marriage.
