The literature on capital controls has (at least) four very serious apples-to-oranges problems: (i) There is no unified theoretical framework to analyze the macroeconomic consequences of controls; (ii) there is significant heterogeneity across countries and time in the control measures...

The European and Asian financial crises are the two most recent major regional crises. This paper compares their origins and evolution. The origins of the two sets of crises were different in some respects, but broadly similar. The two sets of crises also shared similarities in their evolution,...

Debt sustainability is fundamentally a probabilistic concept: Debt is rarely sustainable with probability one. We propose an index of external debt sustainability that reflects this uncertainty. Namely we construct the index as the probability that, at the current exchange rate, net external...

This paper traces the evolution of the Federal Reserve and its engagement with the global economy over the last three decades of the 20th century: 1970 to 2000. The paper examines the Federal Reserve's role in international economic and financial policy and analysis covering four areas: the...

This paper analyzes prudential controls on capital flows to emerging markets from the perspective of a Pigouvian tax that addresses externalities associated with the deleveraging cycle. It presents a model in which restricting capital inflows during boom times reduces the potential outflows...

This paper addresses the agenda for the Group of Twenty (G-20) leaders' meeting in Seoul, Korea in November 2010. This is an opportunity and challenge for Asian leaders in particular. Their test will be, first, to demonstrate that they can responsibly advance economic recovery. They must also...

This paper addresses two central questions for Asia and the world: (1) What is the purpose of Asian regional policy coordination going forward? (2) Will Asian regional policy coordination substitute or complement global policy coordination? The paper examines the potential coverage and content...

This paper presents a simple model of how a small open economy can undervalue its real exchange rate using its capital account policies. The paper presents several properties of such policies, and proposes a rule of thumb to assess their welfare cost. The model is applied to an analysis of...

Over the past 10 years, central banks and governments throughout the developing world have accumulated foreign exchange reserves and other official assets at an unprecedented rate. This paper shows that this official asset accumulation has driven a substantial portion of the recent large global...

Official purchases of foreign assets -- a broad definition of currency intervention -- are strongly correlated with current account (trade) imbalances. Causality runs in both directions, but statistical analysis using instrumental variables reveals that the effect of official asset purchases on...
