U.S. Bank Behavior in the Wake of the 2007–2009 Financial Crisis
Description: The paper examines the slowdown of lending by large U.S. banks over the period 2007Q3 - 2009Q2, focusing on: (i) whether capital or liquidity was the binding constraint; (ii) factors influencing banks’ decision to hold capital; and (iii) their pricing behavior. Using quarterly data for the largest U.S. banks, the paper finds that capital, rather than liquidity, constrained lending. Banks took actions to increase capital by slowing lending and raising profit margins, not fully passing through the Federal Reserve’s interest rate cuts. Banks optimally choose capital based on the expected future demand for loans and the marginal cost of capital.

What Explains the Rise in Food Price Volatility?
Description: The macroeconomic effects of large food price swings can be broad and far-reaching, including the balance of payments of importers and exporters, budgets, inflation, and poverty. For market participants and policymakers, managing low frequency volatility—i.e., the component of volatility that persists for longer than one harvest year—may be more challenging as uncertainty regarding its persistence is likely to be higher. This paper measures the low frequency volatility of food commodity spot prices using the spline- GARCH approach. It finds that low frequency volatility is positively correlated across different commodities, suggesting an important role for common factors. It also identifies a number of determinants of low frequency volatility, two of which—the variation in U.S. inflation and the U.S. dollar exchange rate—explain a relatively large part of the rise in volatility since the mid-1990s.

Dynamic Loan Loss Provisions in Uruguay: Properties, Shock Absorption Capacity and Simulations Using Alternative Formulas
Description: This paper assesses the merits of countercyclical loan loss provisioning in Uruguay. Using a stress test methodology, it quantifies the protection against macroeconomic shocks provided by the stock of dynamic provisions accumulated since 2001 and finds that medium-sized shocks would be fully absorbed, offsetting the additional costs caused by rising specific provisions. In addition, the paper simulates the path of dynamic provisions under the formulas used in Spain, Peru and Bolivia, showing that the alternative paths diverge significantly from the actual buildup and in part better conform to the Uruguayan credit cycle.

Recoveries in the Middle East, North Africa, and Pakistan: Have Macroeconomic Policies Been Effective?
Description: This paper identifies and documents the properties of output gap recessions and recoveries in the Middle East, North Africa, and Pakistan (MENAP) during the 1980 to 2008 period. It goes on to investigate the key determinants of the recoveries. The duration of MENAP countries’ recessions and recoveries has increased from the 1990s to the 2000s. MENAP hydrocarbon exporting countries’ recessions were on average more pronounced in the 2000s, and hydrocarbon importing countries’ recessions milder. Fiscal policy is found to have played a key role during the recoveries to potential output, although with weaker effects for MENAP countries that are more open to trade. Monetary policy is found to have been less effective. This is likely to be related to the fact that many of the MENAP countries have fixed exchange rate regimes and hence have limited room for active monetary policy.

Fiscal Policy and the Current Account
Description: This paper examines the relationship between fiscal policy and the current account, drawing on a larger country sample than in previous studies and using panel regressions, vector autoregressions, and an analysis of large fiscal and external adjustments. On average, a strengthening in the fiscal balance by 1 percentage point of GDP is associated with a current account improvement of 0.2–0.3 percentage point of GDP. This association is as strong in emerging and low-income countries as it is in advanced economies; and significantly higher when output is above potential.

Investigating growth spillovers from Europe
Description: The paper characterizes trade exposure and regional integration in six ASEAN economies during 1997-2008. For this, the paper uses the 2000 Asian Input Output Tables which are extrapolated using National Income Accounts and COMTRADE data. On the demand side, the paper shows that the level and geographical nature of external exposure varies across the ASEANs, and has changed over time. In particular, there was a shift in the external demand exposure of ASEANs from mature markets, including the United States, to China and ROW. In addition, the share of China in East Asia’s final demand, especially investment, rose sharply while that of Japan fell. On the supply side, the paper documents the rise of China into a “global factory” and the steady shift in regional production and integration from Japan and the United States to China.

Oil Windfalls in Ghana: A DSGE Approach
Description: We use a calibrated multi-sector DSGE model to analyze the likely impact of oil windfalls on the Ghanaian economy, under alternative fiscal and monetary policy responses. We distinguish between the short-run impact, associated with demand-related pressures, and the medium run impact on competitiveness and growth. The impact on inflation and the real exchange rate could be moderate, especially if the fiscal authorities smooth oil-related spending or increase public spending’s import content. However, a policy mix that results in both a fiscal expansion and the simultaneous accumulation of the foreign currency proceeds from oil as international reserves—to offset the real appreciation—would raise demand pressures and crowd-out the private sector. In the medium term, the negative impact on competitiveness—resulting from ”Dutch Disease” effects—could be small, provided public spending increases the stock of productive public capital. These findings highlight the role of different policy responses, and their interaction, for the macroeconomic impact of oil proceeds.

Short-Versus Long-Term Credit and Economic Performance: Evidence from the WAEMU
Description: This paper studies the link between financial development and economic growth in the West African Economic and Monetary Union (WAEMU). Using panel data for WAEMU countries over the period 1995-2006, the results suggest that while financial development does support growth in the region, long-term bank financing has a greater impact on economic growth than short-term financing because long-term projects have higher returns adjusted for risks. Given that in the WAEMU short-term credit accounts for about 70 percent of credit to the private sector, WAEMU countries are less able to reap the full benefits of improvements in their financial systems. The results also highlight the importance of macroeconomic stability, a creditor-friendly environment, political stability, and the availability of long-term financial resources in fostering banks’ supply of long-term loans.

Important Elements for Inflation Targeting for Emerging Economies
Description: This is the fifth chapter of a forthcoming monograph entitled "On Implementing Full-Fledged Inflation-Targeting Regimes: Saying What You Do and Doing What You Say." It examines whether certain conditions have to be met before emerging economies can adopt an inflation-targeting regime and provides some empirical evidence on the matter. The issues analyzed are the priority of inflation targeting over other goals, the absence of fiscal dominance, central bank independence, the degree of control over the policy interest rate, a sound methodology for forecasting, and the soundness of financial institutions and markets, and resilience to changes in exchange rates and interest rates.

Fiscal Policy and Macroeconomic Stability: Automatic Stabilizers Work, Always and Everywhere
Description: The paper revisits the link between fiscal policy and macroeconomic stability. Two salient features of our analysis are (1) a systematic test for the government’s ambivalent role as a shock absorber and a shock inducer—removing a downward bias present in existing estimates of the impact of automatic stabilizers—and (2) a broad sample of advanced and emerging market economies. Results provide strong support for the view that fiscal stabilization operates mainly through automatic stabilizers. Also, the destabilizing impact of policy changes not systematically related to the business cycle may not be as robust as suggested in the literature.
