PRESENTATION ABSTRACT

The Social Security Amendments of 1972 and 1977, often referred to as the “Social Security Notch,” have been exploited as a natural experiment by researchers across numerous literatures to estimate causal relationships between income and an array of different outcomes. In this paper, we investigate whether a demographic or sampling shift potentially confounds results from Notch papers that use the Health and Retirement Study (HRS), a popular data source for many of these studies. Specifically, we find a large discontinuous shift in the proportion of non-white respondents in the HRS starting with the 1917 birth cohort (i.e., those adversely affected by the Social Security Amendments), which we conclude is due to sampling problems in the HRS. To determine whether this confounds key results in the literature, we replicate three papers with different empirical approaches that used the HRS in their analysis of the Social Security Notch (Moulton, 2017; Goda et al, 2010; and Moran and Simon, 2006) and test the extent to which the results hold after accounting for the sampling issue. Overall, the results imply that the Social Security Notch literature and other work using the HRS data should carefully consider this issue.
