5 Concluding remarks
Nowadays, global value chains link the different stages of a production process that are located in different countries and promote international specializations. In this paper, we investigate how the final output is distributed across countries as income under international specializations.
We find from our model that the relaxation of financial constraints in the home country is harmful (beneficial) to the opponent country if the elasticity of substitution between the two intermediate goods is sufficiently high (low). We also find that the further relaxation of financial constraints in a country with the financial development than in the opponent country widens the income inequality across the three countries, regardless of the ranking of income between the first and second countries. Moreover, the income inequality within a country is reduced as the financial sector in that country is well developed. In particular, the income inequality within a country is independent of the financial constraints in the opponent country. This result crucially depends upon the fact that there is no international financial market in which agents in the first and second countries can lend and borrow with each other internationally. The extension to introduce an international financial market is left for future research.
