Following Ramsey (1928) theoretical framework, this paper develops a dynamic model where a community is assumed to be importing two forms of foreign capital: external debt and foreign direct investment (FDI). The community is assumed to derive utility from consumption of goods and positive externalities of FDI, while deriving disutility from negative externalities of external borrowing. Results suggest that: first, a higher disutility of debt implies a higher shadow interest rate.1 The higher the utility derived from FDI, however, the lower the shadow interest rate. Second, external borrowing will be attractive as long as the relevant interest rate is less or equal to the net marginal product of capital. Third, the study of the social optimum shows that the externalities that arise from foreign capital do not affect the steady state which is always a saddle point.
