Whether free movement of international capital induces greater risk of foreign exchange rate and balance-of-payments volatility, or not, is an important question in international finance and economic policy making. The paper employs propensity score matching methodologies to estimate the impact of maintaining open capital accounts on the volatility of international capital flows and foreign exchange rates using data for 69 countries, in the sample period 1980-2011. The findings of the study suggest that maintaining an open capital account could contribute to lower foreign exchange rate volatility. It also finds that capital flow management measures may not have an effect on the volatility of short- and long-term capital flows.
