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.

    When Job Earnings Are Behind Poverty Reduction
    (World Bank, Washington, DC, 2012-11) Inchauste, Gabriela ; Azevedo, João Pedro ; Olivieri, Sergio ; Saavedra, Jaime ; Winkler, Hernan
    Improvement in labor market conditions has been the main explanation behind many of the poverty success stories observed in the last decade, that is the primary conclusion of an analysis of changes in poverty by income source. Changes in labor earnings were the largest contributor to poverty reduction for a sample of 16 countries where poverty increased substantially. In 10 of these countries, labor income explained more than half of the change in poverty, and in another 4 countries, it accounted for more than 40 percent of the reduction in poverty. A declining dependency rate accounts for over a fifth of the reduction in poverty in 10 out of 16 countries, while transfers and other non-earned incomes account for more than a quarter of the reduction in poverty in 9 of these countries. A further decomposition of the contribution of labor income to poverty reduction in Bangladesh, Peru, and Thailand found that changes in individual characteristics (education, work experience, and region of residence) were important, but that overall, increases in real earnings among the poor matter the most.

    Understanding Changes in Poverty
    (World Bank Group, Washington, DC, 2014-08-12) Inchauste, Gabriela ; Azevedo, João Pedro ; Essama-Nssah, B. ; Olivieri, Sergio ; Van Nguyen, Trang ; Saavedra-Chanduvi, Jaime ; Winkler, Hernan
    Understanding Changes in Poverty brings together different methods to decompose the contributions to poverty reduction. A simple approach quantifies the contribution of changes in demographics, employment, earnings, public transfers, and remittances to poverty reduction. A more complex approach quantifies the contributions to poverty reduction from changes in individual and household characteristics, including changes in the sectoral, occupational, and educational structure of the workforce, as well as changes in the returns to individual and household characteristics. Understanding Changes in Poverty implements these approaches and finds that labor income growth that is, growth in income per worker rather than an increase in the number of employed workers was the largest contributor to moderate poverty reduction in 21 countries experiencing substantial reductions in poverty over the past decade. Changes in demographics, public transfers, and remittances helped, but made relatively smaller contributions to poverty reduction. Further decompositions in three countries find that labor income grew mainly because of higher returns to human capital endowments, signaling increases in productivity, higher relative price of labor, or both. Understanding Changes in Poverty will be of particular relevance to development practitioners interested in better understanding distributional changes over time. The methods and tools presented in this book can also be applied to better understand changes in inequality or any other distributional change.

    Is Labor Income Responsible for Poverty Reduction? A Decomposition Approach
    (World Bank, Washington, DC, 2013-04) Azevedo, Joao Pedro ; Inchauste, Gabriela ; Olivieri, Sergio ; Saavedra, Jaime ; Winkler, Hernan
    Demographics, labor income, public transfers, or remittances: Which factor contributes the most to observed reductions in poverty? Using counterfactual simulations, this paper accounts for the contribution labor income has made to the observed changes in poverty over the past decade for a set of 16 countries that have experienced substantial declines in poverty. In contrast to methods that focus on aggregate summary statistics, the analysis generates entire counterfactual distributions that allow assessing the contributions of different factors to observed distributional changes. Decompositions across all possible paths are calculated so the estimates are not subject to path-dependence. The analysis shows that for most countries in the sample, labor income is the most important contributor to changes in poverty. In ten of the countries, labor income explains more than half of the change in moderate poverty; in another four, it accounts for more than 40 percent of the reduction in poverty. Although public and private transfers were relatively more important in explaining the reduction in extreme poverty, more and better-paying jobs were the key factors behind poverty reduction over the past decade.
