Sources of Nominal Exchange Rate Fluctuations in South Africa
Description: This paper investigates the sources of fluctuations in the rand-U.S. dollar exchange rate in 2001 and 2002 using an empirical exchange rate model which identifies aggregate supply, aggregate demand, and nominal disturbances as possible sources for exchange rate fluctuations. According to our results, nominal disturbances explain by far most of the rand depreciation in the final quarter of 2001. The fact that the nominal effective exchange rate also depreciated sharply suggests the nominal disturbances were domestically generated. From a preliminary examination of the relative movements in policy interest rates in South Africa and the United States, along with growth rates in both narrow and broad monetary aggregates in South Africa, it is difficult to isolate the underlying cause of the nominal disturbances in 2001 and 2002. Clearly, the task remains a challenging one with the empirical tools available.

External Debt, Public Investment, and Growth in Low-Income Countries
Description: This paper examines the channels through which external debt affects growth in low-income countries. Our results suggest that the substantial reduction in the stock of external debt projected for highly indebted poor countries (HIPCs) would directly increase per capita income growth by about 1 percentage point per annum. Reductions in external debt service could also provide an indirect boost to growth through their effects on public investment. If half of all debt-service relief were channeled for such purposes without increasing the budget deficit, then growth could accelerate in some HIPCs by an additional 0.5 percentage point per annum.

Volatility and Comovement in a Globalized World Economy: An Empirical Exploration
Description: This paper analyzes the evolution of volatility and cross-country comovement in output, consumption, and investment fluctuations using two distinct datasets. The results suggest that there has been a significant decline in the volatility of business cycle fluctuations and a slight increase in the degree of cyclical comovement among industrialized countries over time. However, for emerging market economies, financial globalization appears to have been associated, on average, with an increase in macroeconomic volatility as well as declines in the degree of comovement of output and consumption growth with their corresponding world aggregates.

China'S Integration Into the World Economy: Implications for Developing Countries
Description: Although the rest of the world had waited a long time for China to open up, feelings were mixed when it actually did and began to integrate rapidly with the world economy. With the country’s recent accession to the World Trade Organization (WTO), many of its trading partners are increasingly concerned that China’s competition in the world goods and capital markets may adversely affect their own growth prospects. This paper examines the implications of China’s WTO accession for other developing countries in the context of the country’s long-term process of growth and opening up. The paper argues that China’s integration into the world economy will inevitably impose adjustment costs on its trading partners in the short-to-medium term, but the benefits it generates are likely to dominate in the long run.

Evolution and Performance of Exchange Rate Regimes
Description: Using recent advances in the classification of exchange rate regimes, this paper finds no support for the popular bipolar view that countries will tend over time to move to the polar extremes of free float or rigid peg. Rather, intermediate regimes have shown remarkable durability. The analysis suggests that as economies mature, the value of exchange rate flexibility rises. For countries at a relatively early stage of financial development and integration, fixed or relatively rigid regimes appear to offer some anti-inflation credibility gain without compromising growth objectives. As countries develop economically and institutionally, there appear to be considerable benefits to more flexible regimes. For developed countries that are not in a currency union, relatively flexible exchange rate regimes appear to offer higher growth without any cost in credibility.

Are Credit Default Swaps Spreads High in Emerging Markets: An Alternative Methodology for Proxying Recovery Value
Description: In times of distress when a country loses access to markets, there is evidence that credit default swap (CDS) spreads are a leading indicator for sovereign risk than the EMBI+ sub-index for the country. However, it is not easy to discern the variables that determine the level of CDS spreads in Emerging Markets (EM); traders only quote the CDS spreads and not the inputs that are required to calculate such spreads. This note provides some evidence from Argentina and Brazil that reveals inconsistency between theory and practice in pricing CDS spreads in EM. This note suggests an alternate methodology that links CTD (cheapest-to-deliver) bonds to recovery values assumed in CDS contracts. Furthermore, special features that pertain to CDS contracts (repo specialness, short squeezes by central banks) may also magnify the financial distress of a sovereign.

IMF and the Baltics: A Decade of Cooperation
Description: The paper is an economic history of the IMF’s involvement in the Baltic states. It describes and analyzes the initial economic stabilization; the period of consolidation and recovery; the effects of the Russian crisis of 1998; and the current growth phases of Lithuania, Latvia, and Estonia. There is also an assessment of cooperation with the Fund based on interviews with a number of ex-officials. The major conclusion is that the Baltics have been so successful because of their early commitment to change the stabilization and reform policies needed for successful transition, and their ownership of their IMF-supported programs.

Patterns of Shocks and Regional Monetary Cooperation in South Asia
Description: The member states of the South Asian Association for Regional Cooperation have set as a target the achievement of an economic union by 2020. Reaching this goal will require greater levels of monetary cooperation. How should this be achieved? Data from South Asia suggest that member states have minor trade linkages and face asymmetrical patterns of shocks. This paper concludes that, absent a clear road map for monetary cooperation, the present process must be structured so as to be harmonized with the level of regional economic integration.

U.S. Investors' Emerging Market Equity Portfolios: A Security-Level Analysis
Description: We analyze a unique data set and uncover a remarkable result that casts a new light on the home bias phenomenon. The data are comprehensive, security-level holdings of emerging market equities by U.S. investors. We document, as expected, that at a point in time U.S. portfolios are tilted towards firms that are large, have fewer restrictions on foreign ownership, or are cross-listed on a U.S. exchange. The size of the cross-listing effect is striking. In contrast to the well-documented underweighting of foreign stocks, emerging market equities that are cross-listed on a U.S. exchange are incorporated into U.S. portfolios at full international capital asset pricing model (CAPM) weights. Our results suggest that information asymmetries play an important role in equity home bias and that the benefits of international risk sharing are limited to select firms.

Financial Globalization, Portfolio Diversification, and the Pattern of International Trade
Description: The paper provides a general-equilibrium model where incomplete international financial markets lead to insufficient industrial specialization and low international trade. As international portfolio diversification is limited and productivity is uncertain, investors wish to maintain a diversified industrial structure rather than specializing according to their comparative advantage. Financial globalization then induces more specialization and more trade. The present framework yields explicit closed-form solutions for the volume and the structure of trade. Empirical results support the implications of the theory. Trade in financially open countries is (i) higher, (ii) more dependent on productivity differences, and (iii) less sensitive to industry risks.
