Inflation Targeting and the Crisis: An Empirical Assessment
Description: This paper appraises how countries with inflation targeting fared during the current crisis, with the goal of establishing the stylized facts that will guide and motivate future research. We find that since August 2008, IT countries lowered nominal policy rates by more and this loosening translated into an even larger differential in real interest rates relative to other countries; were less likely to face deflation scares; and saw sharp real depreciations not associated with a greater perception of risk by markets. We also find some weak evidence that IT countries did better on unemployment rates and advanced IT countries have had relatively stronger industrial production performance. Finally, we find that advanced IT countries had higher GDP growth rates than their non-IT peers, but find no such difference for emerging countries or the full sample.

Lessons and Policy Implications from the Global Financial Crisis
Description: The ongoing global financial crisis is rooted in a combination of factors common to previous financial crises and some new factors. The crisis has brought to light a number of deficiencies in financial regulation and architecture, particularly in the treatment of systemically important financial institutions, the assessments of systemic risks and vulnerabilities, and the resolution of financial institutions. The global nature of the financial crisis has made clear that financially integrated markets, while offering many benefits, can also pose significant risks, with large real economic consequences. Deep reforms are therefore needed to the international financial architecture to safeguard the stability of an increasingly financially integrated world.

Current Account Balance Estimates for Emerging Market Economies
Description: This paper uses a modified version of the methodology used by the IMF's Consultative Group on Exchange Rate Issues (CGER) to calculate equilibrium current account balances (or ?norms?) for a sample of 33 emerging market economies. We find that the fundamental determinants of the equilibrium current account balances are similar to those identified by the CGER using a sample that also comprises advanced economies. However, the fiscal balance has a considerably stronger impact on current account norms for emerging markets. This paper also offers estimates for the equilibrium current account balances of eleven smaller emerging market economies that are not currently included in the country sample used by the CGER.

Informal Labour and Credit Markets: A Survey
Description: This paper reviews the literature on the informal economy, focusing first on empirical findings and then on existing approaches to modeling informality within both partial and general equilibrium environments. We concentrate on labour and credit markets, since these tend to be most affected by informality. The phenomenon is particularly important in emerging and other developing economies, given their high degrees of informal labour and financial services and the implications these have for the effectiveness of macroeconomic policy. We emphasize the need for dynamic general equilibrium (DGE) and ultimately dynamic stochastic general equilibrium (DSGE) models for a full understanding of the costs, benefits and policy implications of informality. The survey shows that the literature on informality is quite patchy, and that there are several unexplored areas left for research.

Growth and Capital Flows with Risky Entrepreneurship
Description: This paper shows that the behavior of entrepreneurs facing incomplete financial markets and risky investment can explain why growth accelerations in developing countries tend to be associated with current account improvements. The uninsurable risk of losing invested capital forces entrepreneurs to rely on self-financing, so that when business opportunities open up entrepreneurs increase saving to finance the investment that produces growth. The key insight is that saving has to rise more than investment to allow also for the accumulation of precautionary assets. Plausibly calibrated simulations show that this net saving increase can sustain large and persistent net capital outflows.

Spillovers to Central America in Light of the Crisis: What a Difference a Year Makes
Description: This paper investigates Central America's external linkages over the last fifteen years of increased integration in light of the 2008-09 global recession. Using structural VAR models, it is found that a one percent shock to U.S. growth shifts economic activity in Central America by 0.7 to 1 percent, on average. Spillovers from global shocks and the rest of the region also affect activity in some countries. Spillovers are mostly transmitted through advanced country financial conditions and fluctuations in external demand for Central American exports. Shocks to advanced economies associated with the 2008-09 financial crisis lowered economic activity in the region by 4 to 5 percent, on average, accounting for a majority of the observed slowdown. The impact was almost twice as large as elasticities estimated on pre-crisis data would have predicted. These results underscore the importance of operating credible policy frameworks that enable a countercyclical policy response to external shocks.

Evaluation of the Oil Fiscal Regime in Russia and Proposals for Reform
Description: Oil revenue plays a central role in Russia's economic development. Thus, the recent decline in oil production and investment, and the possible contribution of the current fiscal regime to these developments, have prompted a reassessment of the oil tax system in Russia. Some important changes have already been made, while others are underway. This paper uses a simulation model to evaluate Russia's current oil fiscal regime. Based on these simulations, the paper proposes ways to make the fiscal regime more supportive of investment, while ensuring an appropriate share of oil sector profits for the government.

Optimal Monetary Policy with Overlapping Generations of Policymakers
Description: In this paper I study the effect of imperfect central bank commitment on inflationary outcomes. I present a model in which the monetary authority is a committee that consists of members who serve overlapping, finite terms. Older and younger generations of Monetary Policy Committee (MPC) members decide on policy by engaging in a bargaining process. I show that this setup gives rise to a continuous measure of the degree of monetary authority's commitment. The model suggests that the lower the churning rate or the longer the tenure time, the closer social welfare will be to that under optimal commitment policy.

Constraints on Trade in the MENA region
Description: In this paper we estimate gravity models to see whether trade volumes of countries in the MENA region are significantly lower than what would be expected given their economic, cultural and geographical characteristics. Our empirical results show that the variables used in standard gravity models cannot explain a significant part of MENA's trade performance, particularly on exports. We then go on to 'augment' the standard gravity model with relevant variables from the World Bank's Business Enterprise surveys. Our results further show that these variables, and in particular transport constraints and inefficiencies in customs clearance processes, are important in explaining the MENA region's underperformance in trade.

Constraintson Growth in the MENA Region
Description: In this paper we contribute to the empirical literature on growth in the MENA region by attempting to quantify the impact of the various constraints faced by local businesses highlighted by the World Bank’s Business Enterprise surveys. To the best of our knowledge this dataset has not been used in any empirical analysis looking at the main constraints on growth in the MENA region. Our empirical results suggest that the key direct constraints to growth in the MENA region are difficulties in access to finance, labor skill mismatches and shortages, and electricity constraints.
