High Liquidity Creation and Bank Failures: Do They Behave Differently?
Description: We formulate the “High Liquidity Creation Hypothesis” (HLCH) that a proliferation in the core activity of bank liquidity creation increases failure probability. We test the HLCH in the context of Russian banking, which provides a natural field experiment due to numerous failures experienced over the past decade. Using Berger and Bouwman’s (2009) liquidity creation measures as a comprehensive proxy for overall bank output, we find that high liquidity creation significantly increases the probability of bank failure; this finding survives multiple robustness checks. Our results suggest that regulatory authorities can mitigate systemic distress and reduce the costs of bank failures to society through early identification of high liquidity creators and enhanced monitoring of their funding and investment activities.

Energy Subsidies and Public Social Spending: Theory and Evidence
Description: This paper shows that high energy subsidies and low public social spending can emerge as an equilibrium outcome of a political game between the elite and the middle-class when the provision of public goods is subject to bottlenecks, reflecting weak domestic institutions. We test this and other predictions of our model using a large cross-section of emerging markets and low-income countries. The main empirical challenge is that subsidies and social spending could be jointly determined (e.g., at the time of the budget), leading to a simultaneity bias in OLS estimates. To address this concern, we adopt an identification strategy whereby subsidies in a given country are instrumented by the level of subsidies in neighboring countries. Our Instrumental Variable (IV) estimations suggest that public expenditures in education and health were on average lower by 0.6 percentage point of GDP in countries where energy subsidies were 1 percentage point of GDP higher. Moreover, we find that the crowding-out was stronger in the presence of weak domestic institutions, narrow fiscal space, and among the net oil importers.

Does Basel Compliance Matter for Bank Performance?
Description: The global financial crisis underscored the importance of regulation and supervision to a well-functioning banking system that efficiently channels financial resources into investment. In this paper, we contribute to the ongoing policy debate by assessing whether compliance with international regulatory standards and protocols enchances bank operating efficiency. We focus specifically on the adoption of international capital standards and the Basel Core Principles for Effective Bank Supervision (BCP). The relationship between bank efficiency and regulatory compliance is investigated using the (Simar and Wilson 2007) double bootstrapping approach on an international sample of publicly listed banks. Our results indicate that overall BCP compliance, or indeed compliance with any of its individual chapters, has no association with bank efficiency.

How to Improve the Effectiveness of Monetary Policy in the West African Economic and Monetary Union
Description: The West African Economic and Monetary Union (WAEMU) is a currency union with a fixed exchange rate and limited capital mobility and, therefore, an independent monetary policy in the short run. The Central Bank of West African States (BCEAO) is conducting the single monetary policy with the main goal of preserving price stability and supporting economic growth. However, the effectiveness of its monetary policy remains low, with a weak reaction of market interest rates and inflation to BCEAO’s policy actions. The paper concludes that, while the institutional setup and the instruments of monetary policy are adequate, the transmission mechanism of monetary policy remains constrained by liquidity management practices, shallow and segmented financial markets, and interest rate rigidities. To improve the effectiveness of monetary policy the BCEAO should be more proactive in determining the stance of fiscal policies, develop financial markets, and liberalize controlled interest rates. The BCEAO is undertaking important reforms in these directions.

Tax Policy in MENA Countries: Looking Back and Forward
Description: This paper reviews trends in taxation and revenue in MENA countries over 1990-2012, with a focus on non-resource taxes. On average, non-resource revenues declined slightly, while resource revenues soared. Country experiences vary: rates of main taxes and their revenues tend to be higher in the Magreb than in the Mashreq, except for the value-added tax, where lower rates are associated with equal or higher revenue; most oil producers raise little tax revenues—generally less than 5 percent of GDP—and most have reduced them since the late 1990s. But there are similarities: unlike common experience around the world, income taxes (not indirect taxes) have partially compensated for lost revenue from trade liberalization; revenues from indirect taxes have remained stable; personal income taxes have played an unimportant role as a revenue tool; and fees and stamp duties are significant revenue sources. Looking forward, tax reform challenges will also vary across countries: the Maghreb needs to focus on efficiency-enhancing reforms, especially in capital income and consumption taxes; the Mashreq have some room to increase revenue; and, there are ample opportunities to improve equity and reduce complexity of tax systems in all countries. Finally, the recent decline in oil prices and revenues is a reminder that even resource-rich GCC countries need to lay the basis of a tax system for the future.

Determinants of Firm Profitability in Colombia’s Manufacturing Sector: Exchange Rate or Structural?
Description: The appreciation of the real exchange rate over the past several years is considered one of the key drivers behind the weak performance of Colombia’s manufacturing sector in recent years. This paper examines the effects of the real exchange rate, external and domestic demand, and structural changes on firms’ profitability in Colombia’s manufacturing sector between 2000 and 2012. While export intensive companies have suffered lower profit growth with real exchange rate appreciation,we find no strong evidence that real appreciation has, on average, negatively affected the profitability of manufacturing firms; on the contrary, we find that real appreciation may have increased firms’ profitability by reducing the cost of imported inputs as Colombian manufacturing firms become more domestically oriented. At the same time, some structural changes (related to trade disruption with Venezuela and increased trade competition from China) seem to partially explain the weakness of the manufacturing sector since 2008.

What Drives Interest Rate Spreads in Pacific Island Countries? An Empirical Investigation
Description: Growth has been sluggish in Pacific island countries (PICs). High cost of credit is likely one of the reasons. While the small scale, geographic dispersion, and vulnerability to shocks increase the cost and risk of credit in this country group, there is considerable variability in interest rate spreads both across countries and over time. This paper examines the determinants of lending rates and interest rate spreads in a panel of six PICs, extending the literature that was largely descriptive in nature or focused on a single country. Our results are in line with economic theory. We find that the size of the economy is negatively correlated with spreads, confirming the importance of scale. Inflation appears to have only marginal impact on spreads. High loan loss provisions and nonperforming loans increase the cost of credit. So does banking system concentration. Higher institutional quality is associated with lower spreads.

The Macroeconomic Effects of Public Investment: Evidence from Advanced Economies
Description: This paper provides new evidence of the macroeconomic effects of public investment in advanced economies. Using public investment forecast errors to identify the causal effect of government investment in a sample of 17 OECD economies since 1985 and model simulations, the paper finds that increased public investment raises output, both in the short term and in the long term, crowds in private investment, and reduces unemployment. Several factors shape the macroeconomic effects of public investment. When there is economic slack and monetary accommodation, demand effects are stronger, and the public-debt-to-GDP ratio may actually decline. Public investment is also more effective in boosting output in countries with higher public investment efficiency and when it is financed by issuing debt.

How Important are Debt and Growth Expectations for Interest Rates?
Description: This paper uses a dataset on private-sector risk aversion as well as expectations of long-run growth and debt to explain trends in implied forward rates on government bonds in the G-7 countries. The results show, consistent with the literature, that a one-percent rise in the long-run projected debt-to-GDP ratio causes an increase in bond yields of a relatively modest 1-to-6 basis points. Shocks to growth expectations and risk aversion have been comparatively more successful in explaining the behavior of long-term rates. The findings imply that growth policies rather than long-run projections of fiscal outcomes may be more important in helping influence long-term borrowing costs.

The Potential Macroeconomic Impact of the Unconventional Oil and Gas Boom in the United States
Description: This paper uses two of the IMF's structural macroeconomic models to estimate the potential global impact of the boom in unconventional oil and natural gas in the United States. The results suggest that the impact on the level of U.S. real GDP over roughly the next decade could be significant, but modest, ranging between 1 and 1½ percent. Further, while the impact on the U.S. energy trade balance will be large, most results suggest that its impact on the overall U.S. current account will be negligible. The impact outside of the United States will be modestly positive on average, but most countries dependent on energy exports will be affected adversely.
