Biography
Sergio Olivieri is an economist in the Poverty Reduction and Equity department of the World Bank, based in Washington, DC.  His main research areas are ex-ante analysis of the distributional impact of macroeconomic shocks, understanding the main channels through which economic growth affects poverty reduction, income distribution and multidimensional poverty. Olivieri has published articles about labor informality, polarization, mobility and inequality issues, most of them focused on Latin-American countries. He has also contributed to research reports on inequality, poverty, social cohesion and macroeconomic shocks. Before joining the Bank, Olivieri worked as a consultant for the Inter-American Development Bank, the United Nation Development Program and the European Commission. He has taught courses on micro-simulation and micro-decomposition techniques for public servants and staff in international organizations around the world. He has also worked as an assistant professor of labor economics in the Department of Economics of Universidad National de La Plata in Buenos Aires, and as a researcher in the university's Center of Distributional, Labor and Social Studies.

    Losing the Gains of the Past: The Welfare and Distributional Impacts of the Twin Crises in Iraq 2014
    (World Bank, Washington, DC, 2016-02) Krishnan, Nandini; Olivieri, Sergio
    Iraq was plunged into two simultaneous crises in the second half of 2014, one driven by a sharp decline in oil prices, the other, by the war against the Islamic State in Iraq and Syria. The severity and recurrent nature of these crises demand a fast understanding and quantification of their welfare impact, which is critical for policy makers. This paper employs an innovative extension of the micro-simulation methodology to provide an ex ante estimate and analysis of the complex and dynamic poverty and distributional impact of the twin crises. The results show an almost complete erosion of the welfare gains of the past, with poverty falling back to 2007 levels and a 20 percent increase in the number of the poor. While the incidence of poverty is higher among internally displaced persons than the rest of the population (except in the Islamic State–affected governorates, where poverty is higher), internally displaced persons make up only a small proportion of Iraq's eight million poor in 2014. The rest comprise of households who already lived below the poverty line, or those who have fallen below the poverty line in the face of the massive economic disruptions the country is facing. The welfare impact of the crises varies widely across space, with the largest increases in poverty headcount rates in Kurdistan and the Islamic State–affected governorates. Yet, the poorest regions in the 2014 crisis scenario are the same as in 2012, the currently Islamic State–affected, and the South, with poverty rates of 40 and 30 percent, respectively. Although the simulated results are not strictly comparable to ex post micro data estimates, because of survey coverage constraints, overall the results are very much in line, particularly in Kurdistan and the South.

    Housing, Imputed Rent, and Households' Welfare
    (World Bank, Washington, DC, 2019-08) Ceriani, Lidia; Olivieri, Sergio; Ranzani, Marco
    Housing is the largest durable good consumed by households. As such, any consumption-based measure of welfare, to be comprehensive, must include the value of the flow of services households derive from their dwellings, the so-called imputed rent. However, estimating imputed rents is a daunting task, which researchers and practitioners tend to overlook. This paper is the first attempt to assess the distributional impact of including housing in the welfare aggregate; the paper tests two estimation methods and analyzes four developing countries. The distributional impact cannot be predicted a priori, and evidence suggests it is context and method specific. Although changes in poverty and inequality are always statistically significant, they are only occasionally larger than one percentage point. By contrast, shared prosperity exhibits sizable changes, which might also determine international re-rankings. Albeit the inclusion of imputed rents reshuffles the set of poor households, observed changes in the socioeconomic profiling of the poor are unlikely to affect pro-poor policy design.
