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. Read more

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.

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. Read more
