Abstract
This paper presents a dynamic macroeconomic model that captures key linkages between foreign aid, public investment, growth, and poverty. Public capital is disaggregated into education, core infrastructure, and health. Dutch disease effects associated with aid are accounted for by endogenizing changes in the relative price of domestic goods. The impact of shocks on poverty is assessed through partial elasticities and household survey data. The model is calibrated for Ethiopia and changes in the level of nonfood aid are simulated. The amount by which (nonfood) aid should increase to reach the poverty targets of the Millennium Development Goals is also calculated, under alternative assumptions about the degree of efficiency of public investment.

Publication Roads out of Poverty? Assessing the Links between Aid, Public Investment, Growth, and Poverty Reduction(World Bank, Washington, DC, 2005-01)The authors develop a macroeconomic framework that captures links between aid, public investment, growth, and poverty. Public investment is disaggregated into education, infrastructure, and health, and affects both aggregate supply and demand. Dutch disease effects are captured by accounting for changes in the relative price of domestic goods. The authors assess the impact of policy shocks on poverty by linking the model to a household survey. They calibrate the model for Ethiopia and simulate the changes in the allocation of aid and public investment. The authors also calculate the amount by which foreign aid should increase to reach the poverty targets of the Millennium Development Goals.Publication Linking Public Investment Programs and SPAHD Macro Models : Methodology and Application to Aid Requirements(World Bank, Washington, DC, 2006-06)The authors propose a "bottom up" approach to link public investment programs with a class of macro models recently developed to quantify Strategy Papers for Human Development (SPAHD) in low-income countries. The methodology involves establishing constant-price projections of investment outlays (disaggregated into infrastructure, education, and health), spending on maintenance and other goods and services, salaries, and user charges. These estimates are incorporated in a SPAHD macro framework to calculate, under alternative scenarios, domestic financing, foreign borrowing, and aid requirements. The authors also evaluate the impact on growth and indicators associated with the Millennium Development Goals. They use illustrative applications, based on a SPAHD model for Niger, to highlight the link between tax reform and aid requirements.Publication Achieving the Millennium Development Goals in Sub-Saharan Africa : A Macroeconomic Monitoring Framework(World Bank, Washington, DC, 2005-10)The authors present an integrated macroeconomic approach to monitoring progress toward achieving the Millennium Development Goals (MDGs) in Sub-Saharan Africa. At the heart of their approach is a macroeconomic model that captures key linkages between foreign aid, public investment (disaggregated into education, infrastructure, and health), the supply side, and poverty. The model is linked through cross-section regressions to indicators of malnutrition, infant mortality, life expectancy, and access to safe water. A composite MDG indicator is also calculated. The functioning of the framework is illustrated by simulating the impact of an increase in aid and a debt write-off for Niger at the MDG horizon of 2015, under alternative assumptions about the degree of efficiency of public investment. The authors' approach can serve as the building block of Strategy Papers for Human Development (SPAHD), a more encompassing concept than the current "Poverty Reduction" Strategy Papers.Publication Contracting Models of the Phillips Curve : Empirical Estimates for Middle-Income Countries(World Bank, Washington, DC, 2003-09)This paper provides empirical estimates of contracting models of the Phillips curve for four middle-income developing economies-Chile, the Republic of Korea, the Philippines, and Turkey. Following an analytical review, models with both one lead and one lag, and two lags and three leads, are then estimated using Generalized Method of Moments (GMM) techniques. The results indicate that for both Chile and Turkey past and future inflation are of about the same magnitude in affecting current inflation. In Korea past inflation has a larger impact on inflation, whereas in the Philippines it is future inflation that plays a larger role. Homogeneity restrictions are satisfied for Korea and Turkey, but not for Chile and the Philippines.Publication Linking Representative Household Models with Household Surveys for Poverty Analysis: A Comparison of Alternative Methodologies(World Bank, Washington, D.C., 2004-06)The authors compare three approaches to linking representative-household macro models with micro household income data in terms of their implications for measuring the poverty and distributional effects of policy shocks. These approaches are a simple micro-accounting method, an extension of that method to account for changes in employment structure, and the Beta distribution approach. Even though in the authors simulation exercises the three methods do not lead to fundamentally different results in absolute terms, they show that potential differences in the measurement of distributional and poverty effects of policy shocks can be very large.
