We present an MNE model and conditions for parametric and nonparametric identification. Prior studies rarely found wages to affect MNE employment. We document a complementarity bias when the extensive margin is excluded and detect salient labor substitution at both margins for German manufacturing MNEs. With a one-percent increase in home wages, for instance, MNEs add 2,000 jobs in Eastern Europe at the extensive margin and 4,000 jobs overall; a converse one-percent drop in Eastern European wages removes 730 German MNE jobs.
