The role of exchange rate policies in economic development is still largely debated. This column argues that there are theoretical foundations for policies that guarantee competitive and stable real exchange rates. When there are constraints on the available set of policy instruments, the complementary use of competitive exchange rates with export taxes for traditional export sectors would result in effectively multiple real exchange rates. The empirical evidence suggests that both foreign exchange interventions and capital account regulations can be effectively used for maintaining competitive exchange rates and for dampening the effects of boom-bust cycles in external financing and the terms of trade on the exchange rate, thereby promoting growth and stability.
