Self-esteem and earnings

Recent research in economics suggests a positive association between self-esteem and earnings. Using the National Longitudinal Survey of Youth (NLSY), which administered the Rosenberg Self-Esteem Scale during its 1980 and 1987 interviews, I provide further evidence for the existence of a self-esteem premium by exploiting variation in these measures between the 2 years. I show that self-esteem in 1980 has a sizeable impact on wages 8 years later, controlling for a wide set of individual characteristics and addressing problems of omitted variable bias and reverse causality. The instrumental variables estimate of the effect of self-esteem in 1987 on earnings is about two times greater than previous OLS estimates would imply. The main explanation for this discrepancy is that the previous OLS estimates are biased downward as a result of measurement error in the reported self-esteem measure. (C) 2011 Elsevier B.V.
