PAYG and funding may and do coexist in social security systems. The proportions of this coexistence, however, are quite variable from country to country. The paper examines the US and a number of European countries, looking at both the present state and the foreseeable trends in future decades. The impact of a mixed system is analysed under the relevant viewpoints, with special reference to the adequacy and sustainability of the overall structure and to the distribution of risk.
