TY - RPRT AU - Andini, Corrado TI - The Wage Return to Education: What Hides Behind the Least Squares Bias? PY - 2015/Feb/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 8855 UR - https://www.iza.org/index.php/publications/dp8855 AB - This paper combines the approach by GuimarĂ£es and Portugal (2010) with the methodology of Gelbach (2015) to investigate the determinants of the least squares bias of the wage return to education. We find that disregarding individual fixed effects is highly problematic, accounting for 95% of the bias. In contrast, disregarding firm fixed effects has marginal consequences.
