RT Journal Article SR Electronic T1 Estimating the Return to Endogenous Schooling Decisions via Conditional Second Moments JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 1047 OP 1065 DO 10.3368/jhr.44.4.1047 VO 44 IS 4 A1 Klein, Roger A1 Vella, Francis YR 2009 UL http://jhr.uwpress.org/content/44/4/1047.abstract AB This paper employs conditional second moments to identify the impact of education in wage regressions where education is treated as endogenous. This approach avoids the use of instrumental variables in a setting where instruments are frequently not available. We employ this methodology to estimate the returns to schooling for a sample of Australian workers. We find that accounting for the endogeneity of education in this manner increases the estimated return to education from 6 percent to 10 percent.
