    This confirms the results of von Weizäcker [1999], who lacks the θ(t)-uncertainty and finds thus no diversification potential between the pension pillars.Google Scholar

    Note that as Merton [1983, p. 331] remarks one could alternatively define the price of human capital securities based on the net value of human capital; then they would not yield this extra payoff. The applied definition is without consequences for the equilibrium result and purely for convenience to apply the usual accumulation equation.Google Scholar

    See Bundesministerium für Gesundheit und Soziale Sicherung [2003, p. 103]. Note that already the later revoked reform of 1999 would have made such an adjust?ment: the effect of Rürup’s sustainability-factor is essentially the same as that of the early proposed demographic-factor. Admittedly, it must also be mentioned that the financing problems are partially caused by structural problems on the labor market resulting in economic and unemployment sclerosis. Yet, the transmission mechanism for the PAYGO problems is the same: less workers and a high wage level.Google Scholar
