This paper develops a formal model that looks at the mutually endogenous determination of foreign direct investments in natural resource-rich countries, the decision of host governments to expropriate these investments, and the level of corruption. Higher resource production makes expropriation more attractive from the perspective of national governments. A low expropriation risk is in turn an important determinant of international investments and is therefore associated with high levels of production. Moreover, resource production leads to high levels of corruption. Theoretical results are confirmed by estimations of a simultaneous equation model for 50 resource-rich countries in which the authors endogenize expropriation risk, corruption, and resource production.
