This document provides recent evidence about the persistency of wage gaps between formal and informal workers in Colombia by using a non-parametric method proposed by Ñopo (2008a). Over a rich dataset at a household level during 2008-2012, it is found that formal workers earn between 30 to 60 percent more, on average, than informal workers. Despite of the formality definition adopted, it is clear that formal workers have more economic advantages than informal ones, but after controlling by demographic and labor variables an important fraction of the gap still remains unexplained.
