The Impact of Colombia's Pension and Health Insurance Systems on Informality
This paper examines how changes in the legislation governing health and pension benefits that took place between 2003 and 2008 in Colombia affected the informal and formal labor markets. In particular, this paper examines two major changes in the legislation. First, it looks at the effects of imposing the requirement to use the same base income to contribute to both health insurance and pensions for independent workers using a difference-in-differences strategy.
