The Use of Mortgage Covered Bonds
Description: The rapid mortgage credit growth experienced in recent years in mature and emerging countries has raised some stability concerns. Many European credit institutions in mature markets have reacted by increasing securitization, particularly via mortgage covered bonds. From the issuer's perspective, these instruments have become an attractive funding source and a tool for assetliability management; from the investor's perspective, covered bonds enjoy a favorable risk-return profile and a very liquid market. In this paper, we examine the two largest "jumbo" covered bond markets, Germany and Spain. We show how movements in covered bond prices can be used to analyze the credit developments of the underlying issuer and the quality of its mortgage portfolio. Our analysis also suggests that mortgage covered bonds could be of interest to other mature and emerging markets facing similar risks related to mortgage credit.

The CFA Arrangements: More than Just An Aid Substitute?
Description: The CFA franc zone has had one of the longest experiences with a fixed exchange rate for a convertible currency and regional integration of any group of developing countries. France, the anchor country, provides aid to support the zone. This paper asks whether the arrangements are more than just an aid substitute. The paper addresses this issue by evaluating the overall performance of the zone over the period 1960-2004. The analysis reveals that when the zone is hit by a negative shock, France increases its aid, thereby acting as a shock absorber. However, it also finds that the zone displays strong performance in two areas-price stability and fiscal policy. Thus the paper concludes that the arrangements are not an aid substitute; they have real macroeconomic value for the zone and complement aid.

Lucas vs. Lucas: On Inequality and Growth
Description: Lucas (2004) asserts that "Of the tendencies that are harmful to sound economics, the most seductive, and in my opinion the most poisonous, is to focus on questions of distribution... The potential for improving the lives of poor people by finding different ways of distributing current production is nothing compared to the apparently limitless potential of increasing production." In this paper we evaluate this claim using an extended version of Lucas' (1987) welfare-evaluation framework. Surprisingly, we find that the welfare costs of inequality outweigh the benefits of growth in most cases. These calculations support the case for a research agenda that treats not only growth but also inequality as a priority.

Does Trade and Technology Transmission Facilitate Inequality Convergence? An Inquiry into the Role of Technology in Reducing the Poverty of Nations
Description: Based on stylized evidence showing variation of the Gini coefficient of income inequality across skill cohorts and on the rapid rise in trade in technology-intensive goods, the ripple effects of technology transmission and income inequality are explored in a global Computable General Equilibrium (CGE) framework. An exogenous technology shock transmitted via trade from the United States induces productivity growth in developing regions. This spillover capture-aided by absorptive capability, better governance and institutions, technological symmetry and social acceptance-causes income to increase and income inequality to decline. The conjoined parameters retard growth's inequality-enhancing effect and thus facilitate long-run convergence of inequality between nations.

Mortality and Lifetime Income: Evidence from U.S. Social Security Records
Description: Studies of the empirical relationship between income and mortality often rely on data aggregated by geographic areas and broad population groups and do not distinguish disabled and nondisabled persons. We investigate the relationship between individual mortality and lifetime income with a large micro data base of current and former retired participants in the U. S. Social Security system. Logit models by gender and race confirm a negative relationship. Differences in age of death between low and high lifetime income are on the order of two to three years. Income-related mortality differences between blacks and whites are largest at low-income levels while gender differences appear to be large and persistent across income levels.

China: Strengthening Monetary Policy Implementation
Description: The People's Bank of China (PBC) has made great strides in modernizing its monetary policy frameworks but their effectiveness will diminish as the sophistication of the economy increases. Empirical evidence supports maintaining a reference to money in China's monetary strategy and enhancing the role of interest rates in its conduct. We advocate adoption of an eclectic strategy involving the monitoring of several indicators, and of a short-term interest rate as the operational target. The PBC should be granted discretion to change its policy rate, and there are no technical obstacles for such a move to occur in the near future.

Quasi-Fiscal Deficit in Non-Financial Enterprises
Description: This paper discusses two ways of evaluating the quasi-fiscal deficit (QFD) and the link between them. It also suggests how to properly account for the QFD when calculating the overall deficit of the public sector. Finally, using an example of the energy market, it shows how to untangle a web of mutual nonpayments and properly evaluate the QFD generated in a sector characterized by the presence of both private and public agents.

Monetary Policy Implementation: Results from a Survey
Description: Since the early 1990s, the IMF has been advising countries to shift to the use of indirect instruments for executing monetary policy. This paper provides information about a monetary policy instruments database, maintained by the Monetary and Capital Markets Department of the IMF. We offer an overview of the information contained in the database in the form of comparative summary tables and graphs to illustrate the use of monetary policy instruments by groups of countries (developing, emerging market and developed countries). The main trend that can be identified from the database information is the increasing reliance on money market operations for monetary policy implementation. We emphasize the relevance and usefulness of the data collected through periodic surveys of central banks, for general descriptive and analytical purposes.

Yemen: Exchange Rate Policy in the Face of Dwindling Oil Exports
Description: This paper investigates the likely implications of declining oil production on Yemen's equilibrium exchange rate, and discusses policy options to ensure a smooth transition to a nonoil economy. The empirical results suggest that, as oil production and foreign exchange earnings fall, the Yemeni rial will have to adjust downward in real effective terms to keep pace with the equilibrium exchange rate. In light of strong pass-through from exchange rate depreciation to domestic inflation, this could entail a substantial depreciation in nominal terms. Given the nature of the adjustment, a floating exchange rate regime appears to be the best option, if supported by appropriate macroeconomic policies. However, given public fixation on a exchange rate stability, a softly managed float would be a better option for Yemen whereby the central bank may have to lead the market toward the equilibrium exchange rate.

Debt Dynamics and Global Imbalances: Some Conventional Views Reconsidered
Description: We use a general-equilibrium model to explain the rise in global trade and payments imbalances since the mid-1990s, and then to construct adjustment paths to a steady state. Assuming that the shocks giving rise to the imbalances do not suddenly reverse, simulated movements in the U.S. trade deficit and exchange rate are smaller and more gradual than suggested by partial-equilibrium analyses. An important factor reducing the size of the adjustments is a simulated real interest rate on U.S. external liabilities that is below both the interest rate on external assets and the U.S. real economic growth rate. In addition, the adjustment takes place over an extended period without significantly raising the share of U.S. assets in foreign portfolios, in part because depreciation of the dollar requires continued foreign accumulation of U.S. assets just to keep their portfolio share constant.
