This document examines foreign direct investment (FDI) when multinationals and labour unions bargain over labour contracts and lobby the self-interested government for taxation and labour market regulation. We demonstrate that right-to-manage bargaining predicts higher returns for FDI than does non-unionization or efficient bargaining. This advantage is further magnified in the presence of credible wage contracts. When the labour market is nonunionized, or there is a bargain over employment, the ruling elite reaps the surplus of FDI through taxation or regulation. In the absence of credible contracts, unions have incentives to claim a bigger share of the revenue of FDI.
