This paper documents the main patterns and trends of alternative definitions of labor informality in Latin America and the Caribbean, by exploiting a large database of more than 100 household surveys covering the period 1989-2005. The evidence suggests that there are no signs of a consistent pattern of reduction in labor informality in the region. Regardless of the definition used, labor informality remains a pervasive characteristic of labor markets in LAC. In several countries the increase in labor informality seems to have been associated more to a sizeable increase in the propensity to set informal arrangements within groups, than to changes in the national employment structure toward more informal sectors.(This abstract was borrowed from another version of this item.)
