Saving in Latin America and the Caribbean: Performance and Policies
Description: This paper analyzes saving patterns and determinants in Latin America and the Caribbean (LAC), including key policy variables and regimes. The review of previous empirical studies on LAC saving reveals contradictions and omissions. This paper presents empirical results of an extensive search of determinants of private and public saving rates, adding previously neglected variables (including different measures of key external prices and macroeconomic policy regimes), in linear form and in interactions with other saving determinants. It analyzes statistical differences in saving determinants between LAC and the rest of the world in a nested econometric framework, and discusses differences across three country subgroups within LAC. The results highlight commonalities and differences in saving behavior between LAC and other world regions, as well as within LAC, identifying the role of key policy variables and regimes.

Domestic and Foreign Mutual Funds in Mexico: Do They Behave Differently?
Description: This paper utilizes a new dataset of foreign and domestic mutual funds in Mexico to assess their behavior and obtains three new findings. First, foreign mutual funds are more sensitive to global financial conditions and engage more in herding and positive feedback trading than domestic mutual funds, notably during episodes of market stress. Second, the behavior of foreign funds differs substantially across types of funds: bond funds are more sensitive to global factors and engage more in positive feedback trading than equity funds; funds sold to retail investors, open-end funds, small funds, and regional funds also appear to be less stable sources of capital flows. Third, there is indicative evidence that foreign funds’ trading behavior is associated with higher local market volatilities, notably in periods of market stress; however, domestic mutual fund investors played some mitigating role.

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.

Are African Households Heterogeneous Agents?: Stylized Facts on Patterns of Consumption, Employment, Income and Earnings for Macroeconomic Modelers
Description: This paper reviews the evidence on how households in Sub-Saharan Africa segment along consumption, income and earning dimensions relevant for quantitative macroeconomic policy models which incorporate heterogeneity. Key findings include the importance of home-grown food in the income and consumption of house-holds well up the income distribution, the lack of formal financial inclusion for all but the richest households, and the importance of non-wage income. These stylized facts suggest that an externally-generated macroeconomic shock and the short-term policy response would mainly affect the behavior and welfare of these richer urban households, who are also more likely to have the means to cope. Middle class and poor households, especially in rural areas, should be insulated from these external shocks but vulnerable to a wide range of structural factors in the economy as well as idiosyncratic shocks.

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.
