Externalities of Investment, Education and Economic Growth
نویسندگان
چکیده
We present a growth model in which investment in physical capital shows positive externalities which build up knowledge capital. A prerequisite for these spillovers to take place is that a country devotes time to education. Externalities associated with investment need education to raise the stock of knowledge capital. Analyzing the competitive economy we demonstrate that the model may explain why some low income countries show convergence whereas others do not. Further, we demonstrate that in the social optimum the level of investment is always higher than in the competitive economy whereas the time spent for education may be lower or higher. We also show how the competitive economy may replicate the social optimum for an appropriate choice of a lump-sum tax and an investment subsidy. Empirical evidence is provided in order to demonstrate the plausibility of our model. JEL: O41

We investigate how multinational companies can foster economic development of the host country at the micro level. Traditionally the empirical literature measuring spillovers to the host economy arising from foreign direct investment has focused on productivity spillovers, i.e., technological externalities.
