‘Most emerging and developing economies face a persistent foreign exchange gap. Holding foreign exchange reserves, even in large amounts, does not eradicate the gap that essentially produces persistently foreign exchange constrained economies. This book is a very helpful collection of chapters that elucidates the various manifestations for the foreign exchange constraint. It covers a wide number of important topics such as capital flows, foreign debt, exchange rate policy, the role of MNCs, financial crisis, and others. The collection will be very helpful to researchers and policymakers.’
