RT Journal Article SR Electronic T1 The Effect of the Social Security Earnings Test on Male Labor Supply JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 57 OP 87 DO 10.3368/jhr.43.1.57 VO 43 IS 1 A1 Haider, Steven J. A1 Loughran, David S. YR 2008 UL http://jhr.uwpress.org/content/43/1/57.abstract AB Despite numerous empirical studies, there is surprisingly little agreement about whether the Social Security earnings test affects male labor supply. In this paper, we provide a comprehensive analysis of the labor supply effects of the earnings test using longitudinal administrative earnings data and more commonly used survey data. We find that the response to the earnings test in survey data is obfuscated by measurement error and labor market rigidities. Accounting for these factors, our results suggest a consistent and substantial response to the earnings test, especially for younger men.
