Union Endogeneity and Self-Selection
Abstract
The nature of union endogeneity is examined in the light of recently proposed estimators for union wage differentials. The instrumental variable (IV) approach adopted by Duncan and Leigh is shown to yield little information on the precise nature of the endogenous process. In particular it cannot be used to sign the direction of selection into the union and nonunion sectors since by construction the IV estimates impose opposite signs on the selection terms.
