The Welfare Effects of Social Security with Individual and Aggregate Risk: A Macroeconomic Analysis

这项建议的研究计划的目的是研究当家庭在其生命周期中面临多重风险时，以及当考虑到政策改革的宏观经济反馈时，不同社会保险机构之间的互动对福利的影响。其目的是了解这些相互作用，从而提出如何联合执行教育政策、社会保障政策和再分配政策这一重要问题的答案--无论是通过养恤金制度还是通过失业保险，或者最普遍的是通过一般税收和转移制度--以便在今后几十年减轻人口结构变化带来的不利效率和分配后果。为此目的，对社会保险机构相互作用的分析将对通过退休时养老金支付与工作期间通过税收和转移支付进行福利再分配的最佳福利程度问题提供重要的见解。

The objective of the research program of this proposal is to study the welfare implications of interactions between different social insurance institutions when households face multiple risks in the course of their life-cycle and when macroeconomic feedback of policy reforms is taken into account. The aim is to understand these interactions and thereby to come up with answers to the important question how to jointly implement education policies, social security policies and redistributive policies - either through the pension system or through unemployment insurance or, most generally, the general tax and transfer system - in order to mitigate the adverse efficiency and distributional consequences of demographic change over the next decades. To this purpose, the analysis of interactions of social insurance institutions will provide important insights into the question about the welfare optimal degree of redistribution though pension payments in retirement vis-à-vis through taxation and transfer payments during the working period.
