This paper implements a machine learning approach to estimate intra-generational economic mobility using cross-sectional data. A Least Absolute Shrinkage and Selection Operator (Lasso) procedure is applied to explore poverty dynamics and household-level welfare growth in the absence of panel data sets that follow individuals over time. The method is validated by sampling repeated cross-sections of actual panel data from Peru. In general, the approach performs well at estimating intra-generational poverty transitions; most of the mobility estimates fall within the 95 percent confidence intervals of poverty mobility from the actual panel data. The validation also confirms that the Lasso regularization procedure performs well at estimating household-level welfare growth between two years. Overall, the results are sufficiently encouraging to estimate economic mobility in settings where panel data are not available or, if they are, to improve panel data when they suffer from serious non-random attrition problems.

Fiscal policy is central to not only macroeconomic stability and growth, but also to poverty and inequality reduction. This paper provides the most comprehensive assessment of the distributional incidence of Turkey's fiscal policy to date. It analyzes the combined and individual incidence of direct and indirect taxes, transfers, and social spending and benchmarks Turkey's achievements against peer countries. The results show that fiscal policy significantly reduces income inequality in Turkey, driven by social spending on education and health, and complemented by direct taxes and transfer schemes that countervail the inequality-increasing impact of indirect taxes. At the bottom of the income distribution, targeted transfers are insufficient to compensate for the effect of taxes, resulting in net increases in poverty. In the context of upper-middle-income countries, Turkey's performance is below the median. This is driven by the relatively larger negative impacts of indirect taxes and the more limited positive impacts of direct transfers and taxes. From a policy perspective, the paper contributes to identifying entry points for improving the equity impact of the fiscal package. Among these, targeting the minimum subsistence allowance (AGI) program toward the poor could be an efficient way forward. More broadly, the study represents a platform to simulate the distributional implications of a variety of fiscal changes to inform stakeholders and the policy debate.

Food price inflation in Brazil in the twelve months to June 2008 was 18 percent, while overall inflation was 5.3 percent. This paper uses spatially disaggregated monthly data on consumer prices and two different household surveys to estimate the welfare consequences of these food price increases, and their distribution across households. Because Brazil is a large food producer, with a predominantly wage-earning agricultural labor force, our estimates include general equilibrium effects on market and transfer incomes, as well as the standard estimates of changes in consumer surplus. While the expenditure (or consumer surplus) effects were large, negative and markedly regressive everywhere, the market income effect was positive and progressive, particularly in rural areas. Because of this effect on the rural poor, and of the partial protection afforded by increases in two large social assistance benefits, the overall impact of higher food prices in Brazil was U-shaped, with the middle-income groups suffering larger proportional losses than the very poor. Nevertheless, since Brazil is 80 percent urban, higher food prices still led to a greater incidence and depth of poverty at the national level.

This paper validates a recently proposed method to estimate intra-generational mobility through repeated cross-sectional surveys. The technique allows the creation of a "synthetic panel" - done by predicting future or past household income using a set of simple modeling and error structure assumptions - and thus permits the estimation of lower and upper bounds on directional mobility measures. The authors validate the approach in three different settings where good panel data also exist (Chile, Nicaragua, and Peru). In doing so, they also carry out a number of refinements to the validation procedure. The results are broadly encouraging: the methodology performs well in all three settings, especially in cases where richer model specifications can be estimated. The technique does equally well in predicting short and long-term mobility patterns and is robust to a broad set of additional "stress" and sensitivity tests. Overall, the paper lends support to the application of this approach to settings where panel data are absent.

Over the past decade (2003-12), Latin America has experienced strong income growth and a notable reduction in income inequality, with the region's Gini coefficient falling from 55.6 to 51.8. Previous studies have warned about the sustainability
