ارزیابی یکپارچگی مالی بین المللی در یک اقتصاد مرکز-پیرامون

Does opening up capital markets facilitate risk diversification across borders? Are all countries gradually better off in the process of international financial integration? This paper explores welfare implications for various countries in a center-periphery framework with endogenous portfolio choice. Financial integration is divided into four stages: financial autarky, two-country integration, center-periphery integration and global integration. Two effects from financial integration emerge: diversification effects and financial terms of trade effects. Results show that financial integration between the center and a new periphery in center-periphery integration generates welfare losses for the peripheral country already integrated and welfare gains for the central country. Allowing for financial integration between peripheries in global integration leads the welfare in the center to deteriorate. From two-country integration directly to global integration, the large country gains, while the small one loses.
