The German Retirement Benefit Formula: Drawbacks and Alternatives
نویسندگان
چکیده
In this paper we identify a number of objectionable features of the German retirement benefit formula. We show that groups of insureds with higher than average life expectancy, in particular high-income groups, are subsidized by the rest of the membership because the formula neglects differences in group-specific life expectancy. Furthermore, the current formula leads to undesirable long-run effects if the earnings ceilings is raised, mandatory membership is extended, life expectancy rises or the rate of population growth declines. We present two alternative formulas which take group-specific life expectancy into account. In particular, a return-rate formula which rewards each Euro of contributions with the internal rate of return of the pay-as-you-go pension system proves to be superior to the current formula. JEL-classification: H55, H22, J18.

In most of the multi–criteria decision–analysis (MCDA) problems in which the Choquet integral is used as aggregation function, the coefficients of Choquet integral (capacity) are not known in advance. Actually, they could be calculated by capacity definition methods. In these methods, the preference information of decision maker (DM) is used to constitute a possible solution space. ...
