RT Journal Article SR Electronic T1 Enhancing the Quality of Data on Income JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 758 OP 772 DO 10.3368/jhr.XXXVIII.3.758 VO XXXVIII IS 3 A1 Hurd, Michael A1 Juster, F. Thomas A1 Smith, James P. YR 2003 UL http://jhr.uwpress.org/content/XXXVIII/3/758.abstract AB This paper evaluates two survey innovations introduced in the HRS that aimed to improve income measurement. The innovations are (1) the integration of questions for income and wealth and (2) matching the periodicity over which income questions are asked to the typical way such income is received. Both innovations had significant impacts in improving the quality of income reports. For example, the integration of income questions into the asset module produced in HRS an across-wave 63 percent increase in the amount of income derived from financial assets, real estate investments and farm and business equity. Similarly, asking respondents to answer using a time interval consistent with how income is received substantially improved the quality of reports on social security income. Fortunately, we also suggest ways that these innovations can be introduced into other major social science surveys.
