Estimators that exploit an instrumental variable to correct for misclassification in a binary regressor typically assume that the misclassification rates are invariant across all values of the instrument. We show that this assumption is invalid in routine empirical settings. We derive a new...

Motivated in part by the dramatic changes in the United States economy and public assistance policies, many researchers have examined the changes in the resources of the low-income population over the last two decades, with particular attention paid to income from earnings and public assistance...

The Asset and Health Dynamics Among the Oldest Old (AHEAD) study shows a large increase in reported total wealth between 1993 and 1995. Such an increase is not found in other US household surveys around that period. This paper examines one source of this difference. We find that in AHEAD 1993...

The purpose of this paper is to help empirical economists think through when and how to weight the data used in estimation. We start by distinguishing two purposes of estimation: to estimate population descriptive statistics and to estimate causal effects. In the former type of research,...

The rising cost of college tuition and the accompanying investment parents often make have received considerable attention recently. While classic models in economics make important predictions about the magnitudes of these investments, their distribution across children, and their relationship...

This paper evaluates the effectiveness of recent welfare reforms, investigating the effects of both state-specific waivers in the early 1990s and the 1996 federal reform legislation. Unlike earlier work, we analyze a wide array of indicators, including welfare participation, labor market...

The share of elderly widows living alone rose from 18 percent in 1940 to 62 percent in 1990, while the share living with adult children declined from 59 percent to 20 percent. This study analyzes the causes of this change and finds that income growth, in particular increased Social Security...

If an individual falls on hard times, can he rely on his family for financial support? In view of proposed reductions in public assistance programs, it is important to understand the mechanisms through which families provide support for their members. In this paper we provide evidence that...

Recent work by a number of economists has opened a debate about the role played by intergenerational transfers. Using the new Health and Retirement Survey (HRS), we are better able to address the issues involved. Contrary to the current literature on bequests, we do not find that parents give...

This paper provides the first nationally representative estimates of vulnerability to severe com-plications from COVID-19 overall and across race-ethnicity and socioeconomic status. We use the Panel Study of Income Dynamics (PSID) to examine the prevalence of specific health condi-tions...
