Can the Standard International Business Cycle Model Explain the Relation Between Trade and Comovement?
Description: Recent empirical research finds that pairs of countries with stronger trade linkages tend to have more highly correlated business cycles. We assess whether the standard international business cycle framework can replicate this intuitive result. We employ a three-country model with transportation costs. We simulate the effects of increased goods market integration under two asset market structures, complete markets and international financial autarky. Our main finding is that under both asset market structures the model can generate stronger correlations for pairs of countries that trade more, but the increased correlation falls far short of the empirical findings. Even when we control for the fact that most country-pairs are small with respect to the rest of the world, the model continues to fall short. We also conduct additional simulations that allow for increased trade with the third country or increased TFP shock comovement to affect the country pair's business cycle comovement. These simulations are helpful in highlighting channels that could narrow the gap between the empirical findings and the predictions of the model.

Robbing the Riches: Capital Flight, Institutions, and Instability
Description: Capital flight may undermine economic growth and the effectiveness of debt relief and foreign aid. This paper is the first attempt to test whether unsound macroeconomic policies or weak institutions lead to capital flight, using panel data for a large set of developing, emerging market and transition countries. In addition, the paper tests the revolving door hypothesis that links debt accumulation and capital flight, and analyzes the contribution of institutions to several channels in this relationship.

Sustaining Growth Accelerations and Pro-Poor Growth in Africa
Description: Are improvements in growth in Sub-Saharan Africa (SSA) since the mid-1990s sustainable? What types of growth strategies contribute the most to reducing poverty? This paper examines these questions in four stages. First, it explores the factors contributing to the post- 1995 improvement in growth. Second, to shed some light on factors associated with substantial jumps in growth rates that are sustained in the medium term, an analysis of the correlates of growth accelerations is presented. Third, the paper examines the consistency of the SSA data with some important predictions from the literature directly linking such areas as fiscal policy, financial development, or institutions and growth. Fourth, it reviews recent evidence regarding lessons on the type of growth process that is most effective at raising the incomes of the poor.

Investment Restrictions and Contagion in Emerging Markets
Description: The objectives of this paper are: (1) to analyze an optimal portfolio rebalancing by a fund manager in response to a "volatility shock" in one of the asset markets, under sufficiently realistic assumptions about the fund manager's performance criteria and investment restrictions; and (2) to analyze the sensitivity of the equilibrium price of an asset to shocks originating in other fundamentally unrelated asset markets for a given mix of common investors. The analysis confirms that certain combinations of investment restrictions (notably short-sale constraints and benchmark-based performance criteria) can create additional transmission mechanisms for propagating shocks across fundamentally unrelated asset markets. The paper also discusses potential implications of recent and on-going changes in the investor base for emerging market securities for the asset price volatility.

FDI Flows to Asia: Did the Dragon Crowd Out the Tigers?
Description: China's dramatic success in attracting foreign direct investment (FDI) has raised concerns that it has success diverted FDI from other countries in Asia. We develop a new methodology to estimate crowding out, and we use it to investigate the impact of China's emergence on FDI flows to Asia using data from 14 Asian economies from 1984 to 2002. The results suggest that China did not have much impact on FDI to other countries. In particular, lowincome economies, which compete with China for low-wage investment, and countries with low levels of education or scientific development do not seem to have been especially affected.

Managing Systemic Liquidity Risk in Financially Dollarized Economies
Description: This paper evaluates ways to protect highly dollarized banking systems from systemic liquidity runs (such as the ones that took place recently in Argentina, Uruguay, and Paraguay). In view of the limitations of available (private or official) insurance schemes, and the distortions introduced by central bank lending of last resort (LOLR), the authors favor decentralized liquid foreign asset requirements on dollar deposits, supplemented by a scheme of "circuit breakers." The latter combines the use of limited dollar liquidity to ensure the convertibility of transactional deposits with a mechanism that automatically limits the convertibility of dollar term deposits once triggered by a predetermined decline in banks' liquidity.

Financial De-Dollarization: Is it for Real?
Description: De facto (unofficial) dollarization, defined as the holding by residents of assets and liabilities denominated in a foreign currency, is a policy concern in an increasing number of developing economies. This paper addresses the dollarization debate from this perspective, with the goal of setting the stage for a more detailed and focused discussion of whether de-dollarization should be a policy objective and, if so, how best to pursue this objective. We review existing theories of de facto dollarization and the extent to which they are supported by the available evidence, presents the main strategies for reform, and proposes a list of policy recommendations.

Financial Dollarization Equilibria: A Framework for Policy Analysis
Description: Rapidly rising dollarization and numerous related financial crises in recent years have heightened the need for policy action. This paper contributes to the policy debate by presenting a common analytic framework that examines the roots of de facto financial dollarization under different economic environments and analyzes its interplay with monetary and prudential policies. In addition to providing a systematic analysis of the existence, stability, and multiplicity of dollarization equilibria, the paper makes a few novel contributions. In particular, it stresses the key role played by monetary policy endogeneity and identifies the underlying determinants of the peso premium that are responsible for inducing a preference for the dollar in financial transactions.

The Macroeconomic Challenges of Scaling Up Aid to Africa
Description: This paper surveys the economic literature on the scaling-up of aid to Africa. It provides a checklist of issues that need to be considered when preparing a long term macroeconomic projection for a country involving the assumption of a significant increase in aid. Such scaling-up scenarios are most likely to be developed in the context of a country's efforts to achieve the Millennium Development Goals (MDGs) with the support of the international donor community. The paper stresses that when preparing a scaling-up scenario it is critical to have a detailed understanding of the likely use of additional aid flows.

Subordinated Levy Processes and Applications to Crude Oil Options
Description: One approach to oil markets is to treat oil as an asset, besides its role as a commodity. Speculative and nonspeculative activity by investors in the derivatives markets could be responsible for a sizable increase in oil prices. This paper recognizes both the consumption and investment aspects of crude oil and proposes Levy processes for modeling uncertainty and options pricing. Calibration to crude oil futures' options shows high volatility of oil futures prices, fat-tailed, and right-skewed market expectations, implying a higher probability mass on crude oil prices remaining above the futures' level. These findings support the view that demand for futures contracts by investors could lead to excessively high price volatility.
