 Clearly what position one takes on this will depend on whether one adopts a broadly egalitarian position on intergenerational justice or not. If one thinks that egalitarian commitments should inform our policies towards future generations, and, if one thinks that those alive in the future will be wealthier (a crucial assumption that one might at least query) then there is a case for growth discounting. So one’s verdict on growth discounting will depend on the nature of one’s principle of intergenerational justice (sufficiency, equality, priority, Llavador et al.’s formulation and so on) as well as empirical assumptions about future growth (and one’s attitude to risk and uncertainty).
