Determinants of Banks' Net Interest Margins in Honduras
Description: This paper analyzes the determinants of banks’ net interest margins in Honduras during 1998 to 2013—a period characterized by increasing banks’ net interest margins, foreign bank participation and consolidation. In line with findings in the previous literature, we find that operating costs are the most important drivers of banks’ net interest margins. We also find that competition among banks has led to higher concentration and that funding by parent banks positively impacts foreign banks’ net interest margins. Together, these results suggest that banks, particularly foreign banks, are under pressure to consolidate and reduce operating costs in order to offer competitive interest margins. We conclude that further structural reforms and consolidation may lower banks’ net interest margins.

Sovereign Debt Composition in Advanced Economies: A Historical Perspective
Description: We examine how the composition of public debt, broken down by currency, maturity, holder profile and marketability, has responded to major debt accumulation and consolidation episodes during 1900-2011. Covering thirteen advanced economies, we focus on debt structure shifts that occurred around the two World Wars and global economic downturns, and the subsequent debt consolidations. Notwithstanding data gaps, we are able to recover some broad common patterns. Episodes of large debt accumulation—essentially, large increases in debt supply— were typically absorbed by increases in short-term, foreign currency-denominated, and banking-system-held debt. However, this pattern did not hold during the debt build-ups starting in the 1980s and 1990s, which were compositionally skewed toward long-term local-currency debt. We attribute this change to higher structural demand for sovereign paper, linked to capital account liberalization in advanced economies, the emergence of a large contractual saving sector, and innovative sovereign debt products. With regard to debt consolidations, we find support for the financial repression-cum-inflation channel for post World War II debt reductions. However, the scope for a repeat of this strategy appears limited unless financial liberalization and globalization were materially rolled back or the current globally agreed monetary policy regime built around price stability abandoned. Neither are significant favorable structural demand shifts, as witnessed in the 1980s and 1990s, likely.

Measuring External Risks for Peru: Insights from a Macroeconomic Model for a Small Open and Partially Dollarized Economy
Description: This paper quantifies the effects of external risks for Peru, with particular attention to two major external risks, China’s investment slowdown and the U.S. monetary policy tightening. In particular, a macroeconomic model for a small open and partially dollarized economy is developed and estimated for Peru to measure the risk spillovers, and simulate domestic macroeconomic responses in different scenarios with these two external risks. The simulation results suggest that Peru’s output is vulnerable to both risks, particularly the U.S. monetary policy tightening. Simulations also highlight the importance of higher exchange rate flexiblity and a lower degree of dollarization, which could help mitigate the negative spillover effects of these external risks.

Conventional and Insidious Macroeconomic Balance-Sheet Crises
Description: This paper describes the anatomy of two types of balance-sheet macroeconomic crises. Conventional balance-sheet crises are triggered by external imbalances and balance sheet vulnerabilities. They typically occur after capital inflows have led to a substantial build up of foreign currency exposure. Insidious crises are triggered by internal imbalances and balance sheet vulnerabilities. They occur in high-growth economies when an initially equilibrating shift in relative prices and resources and credit in favor of the nontraded sector overshoots equilibrium. The paper argues that policymakers are now better able to forestall conventional crises, but they are much less capable of early detection and avoidance of insidious crises.

Introducing a Semi-Structural Macroeconomic Model for Rwanda
Description: We develop a simple semistructural model for the Rwandan economy to better understand the monetary policy transmission mechanism. A key feature of the model is the introduction of a modified uncovered interest parity condition to capture key structural features of Rwanda’s economy and policy framework, such as the limited degree of capital mobility. A filtration of the observed data through the model allows us to illustrate the contribution of various factors to inflation dynamics and its deviations from the inflation target. Our results, consistent with evidence for other countries in the region, suggest that food and oil prices as well as the exchange rate have accounted for the bulk of inflation dynamics in Rwanda.

Pacific Island Countries: In Search of a Trade Strategy
Description: International trade is vital for economic prosperity in Pacific island countries, but their trade performance has been weak over the past decade with the exception of resource-rich countries. Small country size and remoteness from global economic centers may have contributed to this relatively poor performance. However, the emergence of Asia as a global economic center presents Pacific island countries with an unprecedented opportunity to develop trade with Asia, particularly in tourism for a number of PICs. Moreover, if a strong two-way linkage is established between tourism and agriculture, Pacific island countries stands a better chance to improve broad-based growth.

Capital Flows, Financial Intermediation and Macroprudential Policies
Description: This paper develops an open-economy DSGE model with an optimizing banking sector to assess the role of capital flows, macro-financial linkages, and macroprudential policies in emerging Asia. The key result is that macro-prudential measures can usefully complement monetary policy. Countercyclical macroprudential polices can help reduce macroeconomic volatility and enhance welfare. The results also demonstrate the importance of capital flows and financial stability for business cycle fluctuations as well as the role of supply side financial accelerator effects in the amplification and propagation of shocks.

Portfolio Flows, Global Risk Aversion and Asset Prices in Emerging Markets
Description: In recent years, portfolio flows to emerging markets have become increasingly large and volatile. Using weekly portfolio fund flows data, the paper finds that their short-run dynamics are driven mostly by global “push” factors. To what extent do these cross-border flows and global risk aversion drive asset volatility in emerging markets? We use a Dynamic Conditional Correlation (DCC) Multivariate GARCH framework to estimate the impact of portfolio flows and the VIX index on three asset prices, namely equity returns, bond yields and exchange rates, in 17 emerging economies. The analysis shows that global risk aversion has a significant impact on the volatility of asset prices, while the magnitude of that impact correlates with country characteristics, including financial openness, the exchange rate regime, as well as macroeconomic fundamentals such as inflation and the current account balance. In line with earlier literature, portfolio flows to emerging markets are also found to affect the level of asset prices, as was the case in particular during the global financial crisis.

Macro-Prudential Policies to Mitigate Financial System Vulnerabilities
Description: Macro-prudential policies aimed at mitigating systemic financial risks have become part of the policy toolkit in many emerging markets and some advanced countries. Their effectiveness and efficacy are not well-known, however. Using panel data regressions, we analyze how changes in balance sheets of some 2,800 banks in 48 countries over 2000–2010 respond to specific macro-prudential policies. Controlling for endogeneity, we find that measures aimed at borrowers––caps on debt-to-income and loan-to-value ratios––and at financial institutions––limits on credit growth and foreign currency lending––are effective in reducing asset growth. Countercyclical buffers are little effective through the cycle, and some measures are even counterproductive during downswings, serving to aggravate declines, consistent with the ex-ante nature of macro-prudential tools.

Unemployment and Structural Unemployment in the Baltics
Description: While the unemployment rate in the Baltics has fallen sharply from its crisis-peaks, it remains close to double digits. This paper estimates the structural component of the jobless rate in the three Baltic countries and analyzes its causes. Our main findings are that the current still elevated levels of unemployment mostly reflect structural factors. We then turn to why structural unemployment is so high. This paper points to skill mismatches, high tax wedges, and unemployment and inactivity traps as potential causes.
