Productivity Growth and the Political Economy of Social Security

The present paper provides an analysis of unfunded social securityas the outcome of a public decision making process in an endogenousgrowth economy. It employs a model in which there is a non-monotonic relationship beween productivity growth and the scale ofpublic intergenerational redistribution. The paper shows thatalthough unfunded social security need not harm growth in general,it is likely to harm growth in a democracy. This effect isreinforced by population aging.
