Poverty and Social Impact Analysis: Linking Macroeconomic Policies to Poverty Outcomes: Summary of Early Experiences
Description: The objective of this paper is to present some early experiences of poverty and social impact analysis (PSIA) from the PRGF-supported programs in the African Department. The paper illustrates that many staff country reports have taken a first step toward PSIA by making more explicit the links between poverty and policies. Various examples highlight that even though relationships can be complex and analysis, as a result, may not be definitive, it is possible to assess some of the potential poverty effects even in countries with limited data, and therefore contribute to a more informed policy debate and design. The paper concludes that PSIA can help design policies that are more pro-poor, better define appropriate compensatory and complementary measures where appropriate, and support country ownership of reforms by promoting a public debate on trade-offs between policy choices. In light of this, the paper proposes that PRGF policy advice would benefit from more systematic PSIA and that staff country reports could report more on the potential policy trade-offs and poverty outcomes based on PSIA.

Taxation and Pricing of Petroleum Products in Developing Countries: A Framework for Analysis with Application to Nigeria
Description: Using the modern theory of public economics as the point of departure, this paper outlines a basic principle for setting taxes and/or prices of commodities based on two key criteria, efficiency and equity. The paper shows that for petroleum products, the basic principle needs modification in the presence of various externalities and market imperfections in a setting where the instruments to address the externalities and imperfections are limited. Drawing from theoretical and empirical literature, the paper provides an operational framework and then illustrates how, for a country like Nigeria, the relevant taxes/subsidies to correct the externalities and to address equity and revenue considerations can be measured with a view to setting prices of petroleum products. However, the paper refrains from making any specific suggestion for policy reform in Nigeria. The framework outlined in the paper can be applied to the analysis of petroleum product taxes and prices in other developing countries.

Exchange Rates in the Periphery and International Adjustment Under the Gold Standard
Description: The role of exchange rate flexibility in the periphery of the gold standard has been grossly overlooked. This paper builds a new dataset on trade-weighed exchange rates for the period 1870-1913 and finds that large currency movements in periphery countries operating inconvertible paper-money and silver-standard regimes induced major fluctuations in effective exchange rates worldwide. We relate the phenomenon to the international trade structure at the time and show that such currency fluctuations had powerful effects on trade flows. We conclude that nominal exchange rate flexibility in the periphery was an important ingredient of international payments adjustment under the gold standard.

The Long-Run Effects of Tradeon Income and Income Growth
Description: This paper examines the dynamic relationship between trade and income. While most economists agree that increased trade leads to an increase in average income, economic theory is ambiguous about the possible effects on the long-run growth rate of the economy. Using a dynamic panel data model, the hypotheses of no long-run effects of trade on income and on income growth are tested explicitly. The possibility of endogeneity is addressed by constructing an instrument for trade by extending Frankel and Romer's (1999) cross-sectional approach to the case of a panel data model. The empirical results indicate that trade has a large and significant effect on the level of income, but the effect on income growth is small and non-robust to model specification.

A Currency Union for the Caribbean
Description: The experiences of Caribbean Economic Community countries show that exchange rate depreciation in these countries is inflationary, and that, while changes in the relative prices of tradables may affect exports, tourism, and imports, nominal exchange rate changes have no predictable effect on those relative prices. Under these circumstances, economic literature indicates that a fixed exchange rate regime is optimal, and Caribbean countries with (quasi-) currency boards have been successful in maintaining durable exchange rate pegs. Commitment to a currency board is a potentially vital step in achieving a currency union for the Caribbean.

Early Warning Systems: A Survey and a Regime-Switching Approach
Description: Previous early-warning systems (EWSs) for currency crises have relied on models that require a priori dating of crises. This paper proposes an alternative EWS, based on a Markov-switching model, which identifies and characterizes crisis periods endogenously; this also allows the model to utilize information contained in exchange rate dynamics. The model is estimated using data for the period 1972-99 for the Asian crisis countries, taking a country-by-country approach. The model outperforms standard EWSs, both in signaling crises and reducing false alarms. Two lessons emerge. First, accounting for the dynamics of exchange rates is important. Second, different indicators matter for different countries, suggesting that the assumption of parameter constancy underlying panel estimates of EWSs may contribute to poor performance.

Some Simulation Properties of the Major Euro Area Economies in Multimod
Description: This paper was prepared as part of a euro area macroeconomic model comparisons project. Four standard macroeconomic experiments are considered to illustrate the differences in dynamic adjustment properties of two versions of MULTIMOD, the IMF's multicountry macroeconomic model. One version of MULTIMOD that is examined contains separate country blocks for the three major economies in the euro area, Germany, France, and Italy. The second, more recent version, contains a single block describing the behavior of the whole euro area.

Trade, Growth, and Poverty: A Selective Survey
Description: This survey of the recent literature asks: how important is trade policy for poverty reduction? We consider the effects of openness on poverty in two components: the effect of openness on average income growth, and the effect on distribution for a given growth rate. Evidence from a variety of sources (cross-country and panel growth regressions, industry and firm-level research, and case studies) supports the view that trade openness contributes greatly to growth. Moreover, trade openness does not have systematic effects on the poor beyond its effect on overall growth. Trade policy is only one of many determinants of growth and poverty reduction. Trade openness has important positive spillovers on other aspects of reform, however, so that the correlation of trade with other pro-reform policies speaks to the advantages of making openness a primary part of the reform package.

Economic Implications of China's Demographics in the 21st Century
Description: This study assesses the economic implications of China's changing population in the 21st century using a numerical general equilibrium model. The simulations show that lower fertility rates yield lower saving rates. Since lower fertility rates reduce the future supply of labor, capital will become less productive. Consequently, if international capital mobility is high in China, a low fertility rate implies more future capital outflows. But if capital is less mobile, low fertility today lowers the domestic return to capital and raises the domestic return to labor. In addition, the paper finds no significant link between demographic structures and per capita income growth.

The Equilibrium Real Exchange Rate of the Malagasy Franc: Estimation and Assessment
Description: Employing cointegration techniques, the long-run determinants of Madagascar's real exchange rate are examined from a stock-flow perspective. The long-run behavior of the real effective exchange rate is explained by the net foreign asset position and factors affecting trade flows. An index of the long-run equilibrium real exchange rate is developed to assess the degree of misalignment. The general conclusions are that the Malagasy franc has experienced significant misalignment in the past, but that the recent appreciation of the real effective exchange rate is consistent with changes in the fundamentals, particularly anticipated improvements in the net foreign assets position stemming from Madagascar's eligibility for assistance under the enhanced HIPC Initiative.
