The role of domestic savings in outward-oriented growth strategies

This paper presents a theory of technological catching-up in which local savings plays a key complementary role to international finance and foreign technology. Until now, the literature has primarily emphasized "outward orientation" as the key ingredient of catching-up success. It has indeed been argued that countries which have relied intensively on foreign technologies, either through capital goods imports or foreign direct investment inflows, have been successful while countries which have opted for inward-oriented growth strategy relying on domestic investment and import-substitution strategies have been unsuccessful. In this paper, we develop a sequential model of industrialization in which domestic savings is key to the success of outward-oriented growth strategies. Indeed, internal finance helps to overcome time-to-adjustment constraints which occur in the early phases of the catching-up process when both advanced foreign technologies and backward domestic ones co-exist. In this model, external finance, though international borrowing, and domestic savings are complementary, not substitutable, in the course of technological catching-up.
