Capital income taxation in endogenous fertility model


  • Watanabe, Minoru
  • Miyake, Yusuke
  • Yasuoka, Masaya


We build a standard overlapping generations model with endogenous fertility and involuntary unemployment. Being different from a log utility function, the capital income tax affects saving at the model of constant relative risk-averse utility function (CRRA function). In the parameter condition, to have the case of non-substitution between consumption in different periods, the capital income tax raises saving to compensate for consumption in the future. Then, results show that a capital income tax improves fertility and unemployment with no social security system.
