Building Supervisory Structures in Sub-Saharan Africa: An Analytical Framework
Description: Current trends in financial sector development in sub-Saharan Africa are prompting policymakers to focus on the design of appropriate supervisory structures. Against the backdrop of worldwide efforts to remodel supervisory structures, this paper develops an analytical framework for designing a regulatory strategy that could assist in prioritizing the needs for regulation and supervision over time. Such a strategy should facilitate the design of a supervisory structure suitable for an individual country's current and future needs. The paper emphasizes that in the case of sub-Saharan Africa, any such strategy is constrained by the reality of capacity limitations and should take into account the need to keep the central bank involved in the process. Building on the framework, the paper identifies a number of supervisory structures that could meet sub-Saharan Africa's needs.

What Should Macroeconomists Know about Health Care Policy?
Description: This primer aims to provide IMF macroeconomists with the essential information they need to address issues concerning health sector policy, particularly when they have significant macroeconomic implications. Such issues can also affect equity and growth and are fundamental to any strategy of poverty reduction. The primer highlights the appropriate roles for the state and market in health care financing and provision. It also suggests situations in which macroeconomists should engage health sector specialists in policy formulation exercises. Finally, it reviews the different health policy issues that confront countries at alternative stages of economic development and the range of appropriate policy options.

Public Debt and Fiscal Vulnerability in the Middle East
Description: Public debt in the Middle East increased during the mid-1990s mainly because of fiscal expansions. It decreased in recent years, thanks to high oil revenue, economic growth, some primary non-oil fiscal adjustment, and debt relief. While countries in the Middle East appear to have adequately reacted to high indebtedness in the past, public debt levels remain uncomfortably high in many, particularly non-oil producing countries and middle income oil producers. Non-oil countries adjust mainly by increasing revenues, whereas oil countries adjust expenditure. For non-oil producing countries, substantial fiscal adjustment would be needed to bring debt down to below 50 percent of GDP. Oil producers as a group appear to follow sustainable, though procyclical, fiscal policies. Middle-income (but not high-income) oil producing countries would need to adjust somewhat to bring their policies in line with the permanent oil income benchmark.

Role of Debt Maturity Structureon Firm Fixed Assets During Sudden Stop Episodes: Evidence From Thailand
Description: This paper studies the detrimental effect of sudden stops on the growth of Thai firms' fixed assets. We focus on the fixed assets adjustment that firms undertake at times of financial constraints. We derive our results from balance sheet data for 284 nonfinancial Thai listed firms. Our data demonstrate that Thai firms faced severe declines in the growth of their fixed assets starting in 1996. Regression results demonstrate, after controlling for firms' characteristics and lagged dependent variables, that holding longer-term debt maturity structure is the factor that works in the firms' favor during sudden stop episodes, while it is their profitability that matters during tranquil periods.

Collateral Damage: Exchange Controls and International Trade
Description: While new conventional wisdom warns that developing countries should be aware of the risks of premature capital account liberalization, the costs of not removing exchange controls have received much less attention. This paper investigates the negative effects of exchange controls on trade. To minimize evasion of controls, countries often intensify inspections at the border and increase documentation requirements. Thus, the cost of conducting trade rises. The paper finds that a one standard-deviation increase in the controls on trade payment has the same negative effect on trade as an increase in tariff by about 14 percentage points. A one standard-deviation increase in the controls on FX transactions reduces trade by the same amount as a rise in tariff by 11 percentage points. Therefore, the collateral damage in terms of foregone trade is sizable.

Can a Rule-Based Monetary Policy Framework Work in a Developing Country? The Case of Yemen
Description: Monetary policy in Yemen is largely rudimentary and ad hoc in nature. The Central Bank of Yemen's (CBY) approach has been based on discretionary targeting of broad money without any clear target to anchor inflation expectations. This paper argues in favor of a new formal monetary policy framework for Yemen emphasizing a proactive and rule-based approach with a greater direct focus on price stability in the context of a flexible management of the exchange rate. Although, as in many developing countries, institutional capacity is a concern, adopting a more formal framework could impel the kind of changes that are required to strengthen the ability of the CBY in achieving low and stable rates of inflation over the medium term.

Banking Sector Integration and Competition in CEMAC
Description: This paper considers the extent of retail banking integration in the Communauté Economique et Monétaire d'Afrique Centrale (CEMAC) and the level of bank competition at the regional level. Using a mix of quantitative and qualitative indicators, the paper finds some evidence of price convergence in average interest rate spreads. However, this observed fact is not supported by an increase in cross-border flows in retail loans and deposits, and price convergence may merely reflect excess liquidity in the region. Other data also indicate that bank competition within the CEMAC as a region is limited, complementing the findings on integration. Addressing shortfalls in legal and regulatory frameworks, infrastructure, and markets would facilitate integration.

Cooperative Banks and Financial Stability
Description: Cooperative banks are an important, and growing, part of many financial systems. This paper empirically analyzes the role of cooperative banks in financial stability. Contrary to some suggestions in the literature, we find that cooperative banks are more stable than commercial banks. This finding is due to the lower volatility of the cooperative banks' returns, which more than offsets their lower profitability and capitalization. This is most likely due to cooperative banks' ability to use customer surplus as a cushion in weaker periods. We also find that in systems with a high presence of cooperative banks, weak commercial banks are less stable than they would be otherwise. The overall impact of a higher cooperative presence on bank stability is positive on average but insignificant in some specifications.

Policy Credibility and Sovereign Credit: The Case of New EU Member States
Description: References to policy credibility, particularly with regard to fiscal policy, are ubiquitous in both economic literature and financial markets, even though it is not directly observable. The case of the EU new member states (NMS)-emerging markets joining a supranational entity that is generally considered to have higher policy credibility-provides a unique experiment to assess the effects of credibility on sovereign credit. This paper examines the impact of EU accession on three key variables that can reflect in varying degrees policy credibility: sovereign ratings, foreign currency spreads, and local currency yields. The results suggest that the NMS appear to have enjoyed higher credibility compared to their peers.

Brazil’s Long-Term Growth Performance—Trying to Explain the Puzzle
Description: This paper assesses Brazil's growth performance from a long-term perspective, using crosscountry and panel estimation techniques, building on the vast empirical literature on growth. The empirical evidence presented in this paper confirms that macroeconomic stability and several reforms have helped raise per capita growth in Brazil since the mid-1990s. The results also show that some long-standing structural weaknesses continue to weigh negatively on per capita growth. Reducing the high level of government consumption would help lower the overall consumption level in the economy and lower its intertemporal price-the real interest rate-thus helping to foster investment and growth.
