Distributional Effects of Oil Price Changeson Household Expenditures: Evidence From Mali
Description: Using an input-output approach, this paper assesses the distributional effects of a rise in various petroleum product prices in Mali. The results show that, although rising gasoline and diesel prices affect mainly nonpoor households, rising kerosene prices are most harmful to the poor. Overall, the impact of fuel prices on household budgets displays a U-shaped relationship with expenditure per capita. Regardless of the oil product considered, highincome households would benefit disproportionately from oil price subsidies. This suggests that a petroleum price subsidy is an ineffective mechanism for protecting the income of poor households compared with a targeted subsidy.

Hong Kong Special Administrative Region: Macroeconomic Impact of an Aging Population in a Highly Open Economy
Description: Hong Kong SAR's population is aging rapidly. This paper concludes that, without a change in policies, aging could adversely affect growth and living standards. While higher labor productivity growth and increased migration of younger skilled workers from the Chinese mainland, would attenuate the economic impact of aging, they would not offset it fully. Aging will also put pressure on public finances, particularly as a result of rising health care costs. There is a relatively narrow window of opportunity to implement policies to lessen the impact of aging, given that the demographic effects could start setting in as early as 2015 when the working population's support ratio peaks. In recent years, the Hong Kong SAR authorities have been focusing on policies that could help limit the fiscal impact of aging, including continued expenditure restraint on non-age-sensitive areas, reform of health care financing (including introducing private health insurance system), and tax reforms.

Adopting Full Dollarization in Postconflict Economies: Would the Gains Compensate for the Losses in Liberia?
Description: This paper discusses whether adopting the U.S. dollar as the sole legal tender could help Liberia, a postconflict economy, to boost growth and strengthen fiscal discipline. In view of the performance of exchange rate regimes in many countries and Liberia's own experience with dollarization, we conclude that Liberia should not adopt full dollarization for the following reasons: (i) the alleged benefits voiced by the proponents of dollarization, in terms of enhanced fiscal discipline and faster economic growth, are not supported by the empirical evidence; (ii) dollarization would increase the Liberian economy's vulnerability to external shocks and Liberia's social fragility; (iii) banks in fully dollarized economies face additional capitalization requirements that Liberian banks cannot meet at present; and (iv) dollarization would be costly in terms of real resources because of the loss of seigniorage.

A Practical Model-Based Approach to Monetary Policy Analysis—Overview
Description: This paper motivates and describes an approach to forecasting and monetary policy analysis based on the use of a simple structural macroeconomic model, along the lines of those in use in a number of central banks. It contrasts this approach with financial programming and its emphasis on monetary aggregates, as well as with more econometrically driven analyses. It presents illustrative results from an application to Canada. A companion paper provides a more detailed how-to guide and introduces a set of tools designed to facilitate this approach.

International Financial Integration, Sovereignty, and Constraints on Macroeconomic Policies
Description: This paper considers the consequences of international financial market integration for national fiscal and monetary policies that derive from the absence of an international sovereign authority to define and enforce contractual obligations across borders. The sovereign immunity of national governments serves as a fundamental constraint on international finance and is used to derive intertemporal budget constraints for sovereign nations and their governments. It is shown that the appropriate debt limit for a country allows for state-contingent repayment. With noncontingent debt instruments, debt renegotiation occurs in equilibrium with positive probability. A model of tax smoothing is adopted to show how information imperfections lead to conventional bond contracts that are renegotiated when a critical level of indebtedness is reached. Renegotiation is interpreted in terms of nominal and real denominated bonds, and implications are drawn about the intertemporal borrowing constraint for monetary policies, the accumulation of reserve assets, and current account sustainability.

Are Asset Price Guarantees Useful for Preventing Sudden Stops?A Quantitative Investigation of the Globalization Hazard-Moral Hazard Tradeoff
Description: An implication of the "globalization hazard" hypothesis is that sudden stops could be prevented by offering foreign investors price guarantees on emerging markets assets. These guarantees create a tradeoff, however, because they weaken globalization hazard by creating international moral hazard. We study this tradeoff using an equilibrium asset-pricing model. Without guarantees, margin calls and trading costs cause Sudden Stops driven by Fisher's debt-deflation process. Price guarantees prevent this deflation by propping up foreign asset demand, but their effectiveness and welfare implications depend critically on the price elasticity of foreign demand and on making the guarantees contingent on debt levels.

Progress in China’s Banking Sector Reform: Has Bank Behavior Changed?
Description: Substantial effort has been devoted to reforming China's banking system in recent years. The authorities recapitalized three large state-owned banks, introduced new governance structures, and brought in foreign strategic investors. However, it remains unclear the extent to which currently reported data reflect the true credit risk in loan portfolios and whether lending decisions have started to be taken on a commercial basis. We examine lending growth, credit pricing, and regional patterns in lending from 1997 through 2004 to look for evidence of changing behavior of the large state-owned commercial banks (SCBs). We find that the SCBs have slowed down credit expansion, but that the pricing of credit risk remains undifferentiated and banks do not appear to take enterprise profitability into account when making lending decisions. Controlling for several factors, we find that large SCBs have continued to lose market share to other financial institutions in provinces with more profitable enterprises. The full impact of the most recent reforms will become clear only in several years, however, and these issues should be revisited in future research.

The External Wealth of Nations Mark II: Revised and Extended Estimates of Foreign Assets and Liabilities, 1970–2004
Description: We construct estimates of external assets and liabilities for 145 countries for the period 1970-2004. We describe our estimation methods and present key features of the data at the country and the global level. We focus on trends in net and gross external positions, and the composition of international portfolios, distinguishing between foreign direct investment, portfolio equity investment, official reserves, and external debt. We document the increasing importance of equity financing and the improvement in the external position for emerging markets, and the differing pace of financial integration between advanced and developing economies. We also show the existence of a global discrepancy between estimated foreign assets and liabilities, and identify the asset categories that account for this discrepancy.

Volatility of Development Aid: From the Frying Pan into the Fire?
Description: The positive impact of foreign aid is limited by the erratic behavior of aid flows. The introduction in 1999 of various initiatives anchored in Poverty Reduction Strategy Papers (PRSPs) which were aimed at strengthening coordination among donors, improving the design of financial support programs, and improving domestic records of policy implementation should have led to an improvement in the time series properties of aid flows. We find no evidence of any fundamental changes in the way aid has been delivered in the past five years. If anything, aid volatility has worsened somewhat and the information value of long-term lending commitments has declined. We take these results to mean that the main causes of the volatility and unpredictability of aid, and the broader issue of macroeconomic instability in low-income countries, have not been addressed in a systematic manner by the donor community.

Is One Watchdog Better Than Three? International Experience with Integrated Financial Sector Supervision
Description: Over the past two decades, there has been a clear trend toward integrating the regulation and supervision of banks, nonbank financial institutions, and securities markets. This paper reviews the international experience with integrated supervision. We survey the theoretical arguments for and against the integrated supervisory model, and use data on compliance with international standards to assess the validity of some of these arguments. We find that (i) full integration is associated with higher quality of supervision in insurance and securities and greater consistency of supervision across sectors, after controlling for the level of development; and (ii) fully integrated supervision is not associated with a significant reduction in supervisory staff.
