Several recent studies use the schooling and wage variation between monozygotic twins to estimate the return to schooling. In this paper, we summarize the results from this literature, and we examine the implications of endogenous determination of which twin goes to school longer and of...

Cross-sectional regression analyses of wage gaps may be biased by omission of unobserved worker characteristics. Recent studies therefore have used longitudinal data to "difference out" the effects of such variables. This paper. however. shows that self-selection of job changers may cause...

This paper discusses the estimation of serial correlation in fixed effects models for longitudinal data. Like time series data, longitudinal data often contain serially correlated error terms, but the autocorrelation estimators commonly used for time series, which are consistent as the length of...

Before 1979, unemployment insurance (UI) benefits were not treated as taxable income in the United States. Several economists criticized this policy on the ground that not taxing UI benefits while taxing earned income allegedly encourages unemployed persons to conduct longer than socially...

"Multigenerational mobility" refers to the associations in socioeconomic status across three or more generations. This article begins by summarizing the longstanding but recently growing empirical literature on multigenerational mobility. It then discusses multiple theoretical interpretations of...

Existing theoretical models of intergenerational transmission of socioeconomic status have strong implications for the association of outcomes across multiple generations of a family. These models, however, are highly stylized and do not encompass many plausible avenues for transmission across...

In this paper we use trends in self-reported disability from the late forties through the late eighties to gauge the impact of the growth of income maintenance for the disabled on the labor force attachment of older working-aged men. Under the assumption that the actual health of these men has...

Labor supply estimates are sensitive to the measures of health used. When self reported measures are used health seems to playa larger role and economic factors a smaller one than when more objective measures are used" While most authors have interpreted these results as an indication of the...

Applicants for Social Security Disability Benefits who fail to pass the medical screening form a natural 'control' group for beneficiaries. Data drawn from the 1972 and 1978 surveys of the disabled done for the Social Security Administration show that fewer than 50% of rejected male applicants...

Several recent studies have found that earnings inequality in Canada has grown considerably since the late 1970's. Using an extraordinary data base drawn from longitudinal income tax records, we decompose this growth in earnings inequality into its persistent and transitory components. We find...
