    In a recent paper, García-Mainar and Montuenga-Gómez [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.
