【主题】Global Demographic Trends and Social Security Reform (written　by Orazio Attanasio, Sagiri Kitao, and Giovanni Violante, Journal of Monetary Economics, 2007)
【摘要】How sustainable are the current social security systems in the deve- loped economies, given the projected demographic trends? The most recent lite- rature has answered this question through dynamic general equilibrium models in a closed-economy framework. This paper provides a new quantitative bench- mark of analysis for this question represented by a two-region model (South and North) of the world economy where capital flows across regions. The timing and the extent of the demographic transition – and the associated economic forces shaping capital accumulation and equilibrium factor prices – are very different in the two regions. Thus, the projected paths of interest rate and wage rate in the North diverge substantially between closed and open economy. We perform a wide range of policy experiments under both scenarios. Our main conclusion is that if one is interested in quantifying the path of the fiscal variables needed to keep the social security system viable or to finance a transition towards a fully funded system, then these two benchmarks yield similar results.
