Quantifying the Inefficiency of the US Social Insurance System

Author

Abstract

How far is the US social insurance system from an efficient system? We answer this question within a model where agents receive idiosyncratic, labor-productivity shocks that are privately observed. When social security and income taxation comprise the social insurance system, the maximum possible efficiency gain is equivalent to a 10:5 percent increase in consumption. This occurs when labor productivity diferences are set to the permanent diferences estimated in US data.
