title = "Comment on Education Returns of Wage Earners and Self-employed Workers",
abstract = "In a recent paper, Garc{\'i}a-Mainar and Montuenga-G{\'o}mez [Econ. Edu. Rev. 24 (2005)] apply the generalized IV model of Hausman and Taylor to estimate education returns of wage earners and the self-employed in Portugal and in Spain. Our examination reveals several problems which relate to the validity and documentation of the instrumental variables, as well as the robustness of the results.",
