The impact of social security reform on the labor market: The case of Colombia

This paper simulates the effects of three increasingly bolder reforms in the Colombian social protection system: the equalization of salaried and self-employed labor contributions; the removal of payroll taxes, parafiscales; and the complete delinking of social protection benefits from labor status. We collect nationally representative information concerning individual willingness to pay for several packages of social security benefits; identify and quantify for the first time three specific distortions caused by existing social security and social assistance systems; and simulate the gains that social protection reforms would bring about in terms of reduced labor distortions. We find that workers in Colombia, regardless of occupation, have a very similar willingness to pay for the full insurance package below 20% of their labor earnings and very similar valuation of social protection services about 50% below par. Labor distortions are large, as expected from very high labor costs, but we quantify an implicit formality tax and informality subsidy ranging between 2 and 27 percent of different representative workers' earnings. Critically, the long-discussed reforms in Colombia including the elimination of parafiscales will not reduce substantially the multiple distortions in its labor market.
