%0 Report %A Koethenbuerger, Marko %A Poutvaara, Panu %A Profeta, Paola %T Why Are More Redistributive Social Security Systems Smaller? A Median Voter Approach %D 2005 %8 2005 Nov %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 1831 %U https://www.iza.org/index.php/publications/dp1831 %X We suggest a political economy explanation for the stylized fact that intragenerationally more redistributive social security systems are smaller. We relate the stylized fact to an "efficiency-redistribution" trade-off to be resolved by political process. The inefficiency of social security financing is due to endogenous labor supply. Using data on eight European countries, we find that the stylized fact and a considerable degree of cross-country variation in contribution rates can be explained by the median voter model. %K public pensions %K applied political economy %K earnings-related and flat-rate benefits %K labor supply
