We propose a Pareto-improving policy which reduces the overall wage taxburden in an economy with intergenerational trade in a fixed factor ofproduction, here labelled as land. We analyse a second-best environmentin which the government cannot resort to non-distortionary land taxes.Reducing the social security contribution rate encourages investment inhuman capital. Future efficiency gains accruing to complementary landare capitalized in its value. The capital gains may compensateland-owning pensioners for reduced benefits. We also explain why theunfunded pension system may have lost its appeal even for pensionersafter its introduction.
