Los efectos de un incremento en el salario mínimo real en los sectores formal e informal

6 minute read

Published:

Estimo el efecto de un incremento en el salario mínimo real en los salarios formales e informales, y en el empleo en Colombia. Encuentro evidencia de respuestas positivas de los salarios cercanos al mínimo. Los resultados muestran que los salarios alrededor del mínimo aumentan más en el sector formal que en el informal. No encuentro que los salarios informales reaccionen al salario mínimo de manera indirecta, a través de vínculos entre el mercado formal y el informal.

The Effects of a Real Minimum Wage Increase in the Formal and Informal Sectors

Published:

I estimate the effect of a real minimum wage increase on formal and informal wages, and on employment in Colombia. I find evidence of positive wage responses for wages close to the minimum wage. The results show that wages increase more in the formal than in the informal sector. I do not find that informal wages react to the minimum wage indirectly, through the linkages between the formal and the informal market.

Descomponiendo la incidencia de la pobreza multidimensional

Published:

Las medidas de pobreza multidimensional se han vuelto estándar como indicadores complementarios de la pobreza en varios países. Proponemos una aplicación de metodologías existentes que descomponen agregados de bienestar, basadas en simulaciones contrafactuales, para dividir los cambios en la pobreza multidimensional en la variación atribuida a cada una de las dimensiones.

Decomposing multidimensional poverty headcounts

Published:

Multidimensional measures of poverty have become standard as complementary indicators of poverty in many countries. We propose 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.

The Consumption of Colombian Households, 2006-2007: Estimation of Demand Systems (In spanish)

Published in Desarrollo y Sociedad, 2010

Using household data from the 2006-2007 Households Income and Expenditure survey, we estimate four different specifications of demand systems for Colombia. We also calculate expenditure, income and price elasticities for different groups of goods.

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.

City Minimum Wages (Job Market Paper)

2017

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.

Consumption Responses to Household Shocks in Colombia

We study the effects of household shocks on consumption across different goods in rural Colombia, using a panel dataset of households. We contrast the estimated effects to those obtained using a structural model of demand.

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

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.
