As mentioned before, the respondents have been asked to evaluate four situations: two situations
without the inclusion of ageing effects (BS and LC or BS and HC), and two with the inclusion of
ageing effects (LB and EB). To get an idea of the evaluations of these variants, the average grades
given by the respondents are presented in table 4.2, both for the total sample and for the separate
generations7.

There appears to be hardly any difference between the evaluations of the basic situation (BS) by the
various generations: all generations prefer the basic situation to all other alternatives presented. The
variation in the evaluations of the situation without ageing, lower contributions and lower public
pension benefits (LC) is also rather small. The middle-aged generation classifies the situation without
ageing and with higher contributions and higher public pension benefits (HC) relatively high, even

6In the questionnaire, respondents got either the situation LC or HC.
