Abstract

Evidence from Iranian Households’ Expenditures and Income Survay(IHEIS) in urban area shows that, average of real hourly wage against the schooling years is declining in the right tail of wage distribution between 1384 and 1390 (2005 and 2011). A tentative justification for this observation is that the private rate of return to education at upper quantiles and higher years of schooling have reduced over the period. We estimate a Mincerian generalized wage equation by making use of quantile regressions with controlling for sample selection problem. Results indicate that the private rate of return to education has decreased between 1390 and 1384. Also educational attaionment reduces wage gap between the upper and lower deciles for females, however a reverse relation is observed for males.
