Debt Dilution and Sovereign Default Risk
Description: We propose a modification to a baseline sovereign default framework that allows us to quantify the importance of debt dilution in accounting for the level and volatility of the interest rate spread paid by sovereigns. We measure the effects of debt dilution by comparing the simulations of the baseline model (with debt dilution) with the ones of the modified model without dilution. We calibrate the baseline model to mimic the mean and standard deviation of the spread, as well as the external debt level, the mean debt duration and a measure of default frequency in the data. We find that, even without commitment to future repayment policies and withoutcontingency of sovereign debt, if the sovereign could eliminate debt dilution, the number of default per 100 years decreases from 3.10 to 0.42. The mean spread decreases from 7.38% to 0.57%. The standard deviation of the spread decreases from 2.45 to 0.72. Default risk falls in part because of a reduction of the level of sovereign debt (36% of the face value and of 11% of the market value). But we show that the most important effect of dilution on default risk results from a shift in the set of government's borrowing opportunities. Our analysis is also relevant for the study of other credit markets where the debt dilution problem could be present.

Sovereign Rating News and Financial Markets Spillovers: Evidence from the European Debt Crisis
Description: This paper examines the spillover effects of sovereign rating news on European financial markets during the period 2007-2010. Our main finding is that sovereign rating downgrades have statistically and economically significant spillover effects both across countries and financial markets. The sign and magnitude of the spillover effects depend both on the type of announcements, the source country experiencing the downgrade and the rating agency from which the announcements originates. However, we also find evidence that downgrades to near speculative grade ratings for relatively large economies such as Greece have a systematic spillover effects across Euro zone countries. Rating-based triggers used in banking regulation, CDS contracts, and investment mandates may help explain these results.

Capital Flows to EU New Member States: Does Sector Destination Matter?
Description: The recent boom-bust episode in Emerging Europe was largely the product of surges and sudden stops in capital inflows. This paper empirically argues that the sectors into which capital flows determines their impact on GDP growth. Applying data from EU New Member States, it is found that capital flows into real estate have a greater impact on swings in GDP than other sectors, irrespective of a country's exchange rate or fiscal policy. Consequently, as new waves of capital inflows spread to emerging markets, policies may usefully focus on supporting capital inflows towards economic sectors that minimize large swings in GDP.

Making OTC Derivatives Safe—A Fresh Look
Description: Recent regulatory efforts, especially in the U.S. and Europe, are aimed at reducing moral hazard so that the next financial crisis is not bailed out by tax payers. This paper looks at the possibility that central counterparties (CCPs) may be too-big-to-fail entities in the making. The present regulatory and reform efforts may not remove the systemic risk from OTC derivatives but rather shift them from banks to CCPs. Under the present regulatory overhaul, the OTC derivative market could become more fragmented. Furthermore, another taxpayer bailout cannot be ruled out. A reexamination of the two key issues of (i) the interoperability of CCPs, and (ii) the cost of moving to CCPs with access to central bank funding, indicates that the proposed changes may not provide the best solution. The paper suggests that a tax on derivative liabilities could make the OTC derivatives market safer, particularly in the transition to a stable clearing infrastructure. It also suggests reconsideration of a "public utility" model for the OTC market infrastructure.

Creditless Recoveries
Description: Recoveries that occur in the absence of credit growth are often dubbed miracles and named after mythical creatures. Yet these are not rare animals, and are not always miracles. About one out of five recoveries is "creditless", and average growth during these episodes is about a third lower than during "normal" recoveries. Aggregate and sectoral data suggest that impaired financial intermediation is the culprit. Creditless recoveries are more common after banking crises and credit booms. Furthermore, sectors more dependent on external finance grow relatively less and more financially dependent activities (such as investment) are curtailed more during creditless recoveries.

Evaluating GDP Forecasting Models for Korea
Description: This paper develops a new forecasting framework for GDP growth in Korea to complement and further enhance existing forecasting approaches. First, a range of forecast models, including indicator- and pure time-series models, are evaluated for their forecasting performance. Based on the evaluation results, a new forecasting framework is developed for GDP projections. The framework also generates a data-driven reference band for the projections, and is therefore convenient to update. The framework is applied to the current World Economic Outlook (WEO) forecast period and the Great Recession to compare its performance to past projections. Results show that the performance of the new framework often improves the forecasts, especially at quarterly frequency, and the forecasting exercise will be better informed by cross-checking with the new data-driven framework projections.

How Big (Small?) are Fiscal Multipliers?
Description: We contribute to the intense debate on the real effects of fiscal stimuli by showing that the impact of government expenditure shocks depends crucially on key country characteristics, such as the level of development, exchange rate regime, openness to trade, and public indebtedness. Based on a novel quarterly dataset of government expenditure in 44 countries, we find that (i) the output effect of an increase in government consumption is larger in industrial than in developing countries, (ii) the fisscal multiplier is relatively large in economies operating under predetermined exchange rate but zero in economies operating under flexible exchange rates; (iii) fiscal multipliers in open economies are lower than in closed economies and (iv) fiscal multipliers in high-debt countries are also zero.

Fiscal Expectations Under the Stability and Growth Pact: Evidence from Survey Data
Description: The paper uses survey data to analyze whether financial market expectations on government budget deficits changed in France, Germany, Italy, and the United Kingdom during the period of the Stability and Growth Pact (SGP). Our findings indicate that accuracy of financial expert deficit forecasts increased in France. Convergence between the European Commission's and market experts’ deficit forecasts also increased in France, Italy, and the United Kingdom, particularly during the period after SGP’s reform in 2005. Yet, convergence between markets’ forecasts and those of the French, German, and Italian national fiscal authorities seems not to have increased significantly during the SGP.

Current Account Rebalancing and Real Exchange Rate Adjustment Between the U.S. and Emerging Asia
Description: A reduction in the U.S. current account deficit vis-à-vis emerging Asia involves a shift in demand from U.S. to emerging Asia tradable goods and a change in international relative prices. This paper quantifies the required adjustment in the terms of trade and real exchange rates in a three-country open economy model of the U.S., China, and other emerging Asia. We compare scenarios where both Chinese and other emerging Asian export prices change by the same proportion to the case where export prices remain constant in one country and increase in the other. Our results are robust to different assumptions about elasticities of substitution and to introducing a high degree of vertical fragmentation in production in the model.

Sovereign Credit Ratings and Spreads in Emerging Markets: Does Investment Grade Matter?
Description: Sovereign investment grade status is often associated with lower spreads in international markets. Using a panel framework for 35 emerging markets between 1997 and 2010, thispaper finds that investment grade status reduces spreads by 36 percent, above and beyond what is implied by macroeconomic fundamentals. This compares to a 5-10 percent reduction in spreads following upgrades within the investment grade asset class, and no impact formovements within the speculative grade asset class, ceteris paribus. While global financial conditions play a central role in determining spreads, market sentiment improves with lower external public debt to GDP levels and higher domestic growth rates.
