The Puzzle of Brazil's High Interest Rates
Description: This paper highlights that real interest rates in Brazil have declined substantially over time, but are still well above the average of emerging market inflation targeting regimes. The adoption of an inflation-targeting regime and better economic fundamentals (reduction in inflation volatility and improvements in the fiscal and external positions) has helped Brazil sustain significantly lower real interest rates than in the past. Going forward, the paper shows that Brazil can converge towards lower equilibrium real interest rates if domestic savings increase to the level of other emerging market countries. The effect is particularly pronounced if the increase in domestic savings is achieved through higher levels of public savings. Still, econometric results suggest that, controlling for everything else in the model, real interest rates in Brazil are about two full percentage points higher than in other countries in the sample, suggesting that there are still Brazil-specific factors that have not been captured by the empirical analysis. Some of these factors may include credit market segmentation and inflation inertia generated by still pervasive indexation practices.

Current Account Imbalances: Can Structural Policies Make a Difference?
Description: The discussion of global and regional imbalances has put the spotlight on the possible link between current accounts and structural policies. Drawing on standard empirical current account models, the paper finds that the commonly recommended structural factors cannot explain the widening of imbalances prior to the 2008 - 09 crisis. That said, structural factors do help explain some part of long-standing cross-country differences in the current account levels. In particular, countries with stricter credit market regulation, higher taxes on businesses, lower minimum wage (in particular,in slow growing economies) and generous unemployment benefits tend to have higher current account balances than others.

Does Central Bank Capital Matter for Monetary Policy?
Description: Heavy foreign exchange intervention by central banks of emerging markets have lead to sizeable expansions of their balance sheets in recent years?accumulating foreign assets and non-money domestic liabilities (the latter due to sterilization operations). With domestic liabilities being mostly of short-term maturity and denominated in local currency, movements in domestic monetary policy interest rates can have sizable effects on central bank's net worth. In this paper we examine empirically whether balance sheet considerations influence the conduct of monetary policy. Our methodology involves the estimation of interest rate rules for a sample of 41 countries and testing whether deviations from the rule can be explained by a measure of central bank financial strength. Our findings, using linear and nonlinear techniques, suggests that central bank financial strength can be a statistically significant factor explaining large negative interest rate deviations from "optimal" levels.

Systemic Real and Financial Risks: Measurement, Forecasting, and Stress Testing
Description: This paper formulates a novel modeling framework that delivers: (a) forecasts of indicators of systemic real risk and systemic financial risk based on density forecasts of indicators of real activity and financial health; (b) stress-tests as measures of the dynamics of responses of systemic risk indicators to structural shocks identified by standard macroeconomic and banking theory. Using a large number of quarterly time series of the G-7 economies in 1980Q1-2010Q2, we show that the model exhibits significant out-of sample forecasting power for tail real and financial risk realizations, and that stress testing provides useful early warnings on the build-up of real and financial vulnerabilities.

India's Growth Spillovers to South Asia
Description: This study investigates the role of India's economy in explaining the observed growth in South Asia, taking into consideration other sources of growth endogenous to the countries in the region. Since a review of key variables indicates that India's bilateral trade and financial linkages with South Asian countries (SAC) are relatively weak, the paper analyses the spillover effects by focusing on growth more generally with India's growth as an explanatory variable. The results of the panel growth regressions suggest that India's growth has good explanatory power for growth in other SAC after 1995.

Coincident Indicators of Capital Flows
Description: Capital flows data from Balance of Payments statistics often lag 3-6 months, which renders timely surveillance and policy deliberation difficult. To address the tension, we propose two coincident composite indicators for capital flows that improve upon existing proxies. We find that the most widely used proxy, the capital tracker, often overpredicts net flows by 30 percent. We augment the tracker into a composite indicator by assigning to it a lesser but optimally estimated weight while incorporating other regional and global coincident correlates of capital flows. The proposed composite indicator of net flows outperforms the capital tracker in its original format. To complement the indicator with an even timelier variant, we also utilize the EPFR high frequency coverage of gross bond and equity flows as an indicator on foreign investors' sentiment.

Can Institutional Reform Reduce Job Destruction and Unemployment Duration? Yes it Can
Description: We read search theory's unemployment equilibrium condition as an Iso-Unemployment Curve(IUC).The IUC is the locus of job destruction rates and expected unemployment durations rendering the same unemployment level. A country's position along the curve reveals its preferences over the destruction-duration mix, while its distance from the origin indicates the unemployment level at which such preferences are satisfied Using a panel of 20 OECD countries over 1985-2008, we find employment protection legislation to have opposing efects on destructions and durations, while the effects of the remaining key institutional factors on both variables tend to reinforce each other. Implementing the right reforms could reduce job destruction rates by about 0.05 to 0.25 percentage points and shorten unemployment spells by around 10 to 60 days. Consistent with this, unemployment rates would decline by between 0.75 and 5.5 percentage points, depending on a country's starting position.

Short-Term Wholesale Funding and Systemic Risk: A Global Covar Approach
Description: In this paper we identify some of the main factors behind systemic risk in a set of international large-scale complex banks using the novel CoVaR approach. We find that short-term wholesale funding is a key determinant in triggering systemic risk episodes. In contrast, we find no evidence that a larger size increases systemic risk within the class of large global banks. We also show that the sensitivity of system-wide risk to an individual bank is asymmetric across episodes of positive and negative asset returns. Since short-term wholesale funding emerges as the most relevant systemic factor, our results support the Basel Committee's proposal to introduce a net stable funding ratio, penalizing excessive exposure to liquidity risk.

Fiscal Performance, Institutional Design and Decentralization in European Union Countries
Description: This paper analyzes the impact of decentralization on overall fiscal performance in the European Union, taking into account fiscal institutional arrangements. We find that spending decentralization has been associated with sizably better fiscal performance, especially when transfer dependency of subnational governments is low. However, subnational fiscal rules do not seem to be associated with better performance.

Precautionary Savings in the Great Recession
Description: Heightened uncertainty since the onset of the Great Recession has materially increased saving rates, contributing to lower consumption and GDP growth. Consistent with a model of precautionary savings in the face of uncertainty, we find for a panel of advanced economies that greater labor income uncertainty is significantly associated with higher household savings. These results are robust to controlling for other determinants of saving rates, including wealth-to-income ratios, the government fiscal balance, demographics, credit conditions, and global growth and financial stress. Our estimates imply that at least two-fifths of the sharp increase in household saving rates between 2007 and 2009 can be attributed to the precautionary savings motive.
