The Minimum Wage in Formal and Informal Sectors: Evidence from an Inflation Shock in Colombia (Under Review)

Listed in Banco de Mexico Research Papers

I estimate the effect of the minimum wage on formal wages, informal wages, and employment in Colombia. I exploit an unexpected increase in the real minimum wage during the 1999 Colombian economic crisis to estimate short- term effects of the minimum wage along the distribution of wages in both sectors. I find evidence of wage responses, with a stronger incidence in the formal sector.

Unpacking the MPI : A Decomposition Approach of Changes in Multidimensional Poverty Headcounts

Listed in World Bank Policy Research Working Paper Series

Coverage: Vox Lacea

Blog post

Multidimensional measures of poverty have become standard as complementary indicators of poverty in many countries. This paper proposes an application of existing methodologies that decompose welfare aggregates -based on counterfactual simulations- to break up the changes of the multidimensional poverty headcount into the variation attributed to each of its dimensions.

City Minimum Wages (Job Market Paper)


Winner of the 2018 S4 Graduate Student Paper Prize

Local minimum wage laws are becoming common across U.S. cities, and their effects may be different from effects of state or nation-wide minimum wage policies. I study the effect of changes in minimum wages on spatial equilibria in local labor markets. Using residence and workplace data for the U.S., I analyze how commuting, residence and work locations change across city and state borders when minimum wages change on either side of the border.

Grading Fiscal Policy in Latin America in the Last Decade

Published in IDB Policy Briefs, 2014

Fiscal policy in Latin America has been historically imprudent and continues to be viewed with skepticism. At the same time, most countries have remained out of trouble for several years and were able to successfully conduct proactive countercyclical fiscal policy to fight the Great Recession, a historical first. This paper examines the last decade to assess progress, highlight weaknesses, and chart the way forward.
