Investigating Inflation Dynamics in Sudan
Description: This paper investigates inflation dynamics in Sudan using three different approaches: the single equation model, the structural vector-auto regression model and a vector error correction model. This is the first study in a low-income and a post-conflict country that uses these three separate techniques to understand inflation dynamics. The use of these approaches is particularly useful to check the robustness of the estimated parameters in the model for a country with limited data coverage and possible structural breaks. The estimated results suggest that money supply growth and nominal exchange rate changes affect inflation with 18-24 months time lag.

What Goes Up Must Come Down? House Price Dynamics in the United States
Description: This paper estimates the evolution of equilibrium real home prices in the United States and finds that despite recent declines, single-family homes remained 8 to 20 percent overvalued as of the first quarter of 2008. In the short run, the gap between actual and equilibrium prices does not exert powerful influence over price dynamics. Instead, that dynamics is driven by the inventory-to-sales ratio and by foreclosure starts in a highly inertial relationship. Taken together, this implies that price declines are likely to continue, including past the point where overvaluation is eliminated. The paper also finds that from the early 1990s onwards changes in regional home prices have been more synchronized than before, and that the recent movements in the average price index have reflected a nationwide housing boom, followed by a nationwide housing bust.

Rising Income Inequality: Technology, or Trade and Financial Globalization?
Description: We examine the relationship between trade and financial globalization and the rise in inequality in most countries in recent decades. We find technological progress as having a greater impact than globalization on inequality. The limited overall impact of globalization reflects two offsetting tendencies: whereas trade globalization is associated with a reduction in inequality, financial globalization-and foreign direct investment in particular-is associated with an increase. A key finding is that both globalization and technological changes increase the returns on human capital, underscoring the importance of education and training in both developed and developing countries in addressing rising inequality.

Central Bank Financial Strength and Policy Performance: An Econometric Evaluation
Description: The financial health of central banks and its relation to policy outcomes has recently been recognized as an important policy issue. While case study evidence clearly indicates that weak central bank finances can hamper effective policy implementation, the question of whether central bank financial strength influences policy performance remains controversial. This is due, in part, to a lack of econometric evidence. The paper presents a first step toward filling this gap, by providing a quantitative evaluation of the relationship between measures of central bank financial strength and policy performance, in particular inflation. The paper's major finding is that there indeed is a negative relationship between central bank financial strength and inflation outcomes. This relationship appears to be robust to the choice of alternative country samples, control variables, estimation strategies, and conceptualizations of central bank financial strength.

Determinants of Foreign Currency Borrowing in the New Member States of the EU
Description: The paper investigates the determinants of foreign currency borrowing by the private sector in the new member states of the European Union. We find that striking differences in patterns of foreign currency borrowing between countries are explained by the loan-to-deposit ratios, openness, and the interest rate differential. Joining the EU appears to have played an important role, by providing direct access to foreign funding, offering hedging opportunities through greater openness, lending credibility to exchange rate regimes, and raising expectations of imminent euro adoption. The empirical evidence suggests that regulatory policies to slow foreign currency borrowing have had only limited success.

Africa’s Oil Abundance and External Competitiveness: Do Institutions Matter?
Description: This paper examines the structural competitiveness of oil-rich economies in sub-Saharan Africa relative to other major oil-exporting developing countries, and investigates reasons for systematic differences in the non-oil export performance across these economies. The analysis reveals that oil-rich Africa lags behind other oil-exporters in terms of diversification, global market share and the overall investment climate. The poor performance of their nonoil sector can be largely attributed to weak infrastructure and institutional quality. The results also show that institutional quality is a significant determinant of the extent to which oil abundance affects the competitiveness of the non-oil sector; thereby explaining the divergent experiences of oil-rich economies across the world. This implies that oil wealth does not necessarily weaken the non-oil tradable sector; countries may mitigate the impact of Dutch disease and benefit from oil booms if revenues are used prudently to reduce oil dependence.

Natural Resource Endowments, Governance, and the Domestic Revenue Effort: Evidence from a Panel of Countries
Description: The recent development literature stresses that countries that receive large revenues from natural resource endowments typically raise less revenue from domestic taxation, and that this creates governance problems because the lower domestic tax effort reduces the incentive for the public scrutiny of government. Our results from a panel of 30 hydrocarbon producing countries indicate that the offset between hydrocarbon revenues and revenues from other domestic sources is about 20 percent but that it is invariant to governance indicators.

Do the Gulf Oil-Producing Countries Influence Regional Growth? The Impact of Financial and Remittance Flows
Description: This paper tests the association between the Gulf Cooperation Council (GCC) countries' financial and remittance outflows and regional growth in the Middle East. The findings, based on 35-year panel data, indicate that growth rates of real GDP, private consumption and private investment in regional countries are strongly associated with remittance outflows from and the accumulation of financial surpluses in the GCC. Unlike in other developing and emerging market countries, growth in regional countries is not influenced by growth in the North, and is not export led. Linkages with the GCC could help sustain output growth in the regional countries in the face of the global economic slowdown and oil price shocks and could provide diversification gains to international capital seeking markets uncorrelated with Northern and emerging market countries.

The Information Content of Money in Forecasting Euro Area Inflation
Description: This paper contributes to the debate on the role of money in monetary policy by analyzing the information content of money in forecasting euro-area inflation. We compare the predictive performance within and among various classes of structural and empirical models in a consistent framework using Bayesian and other estimation techniques. We find that money contains relevant information for inflation in some model classes. Money-based New Keynesian DSGE models and VARs incorporating money perform better than their cashless counterparts. But there are also indications that the contribution of money has its limits. The marginal contribution of money to forecasting accuracy is often small, money adds little to dynamic factor models, and it worsens forecasting accuracy of partial equilibrium models. Finally, non-monetary models dominate monetary models in an all-out horserace.

Vacation Over: Implications for the Caribbean of Opening U.S.-Cuba Tourism
Description: An opening of Cuba to U.S. tourism would represent a seismic shift in the Caribbean's tourism industry. This study models the impact of such a potential opening by estimating a counterfactual that captures the current bilateral restriction on tourism between the two countries. After controlling for natural disasters, trade agreements, and other factors, the results show that a hypothetical liberalization of Cuba-U.S. tourism would increase long-term regional arrivals. Neighboring destinations would lose the implicit protection the current restriction affords them, and Cuba would gain market share, but this would be partially offset in the short-run by the redistribution of non-U.S. tourists currently in Cuba. The results also suggest that Caribbean countries have in general not lowered their dependency on U.S. tourists, leaving them vulnerable to this potential change.
