Undiscounted utilitarianism as a criterion of intergeneration justice has been questioned for different reasons: It has been argued (1) that any complete ordering of allocations with an infinite number of generations guaranteeing an optimal allocation must involve discounting, and (2) that...

Weitzman shows that capital gains should be excluded from NNP. This result is somewhat deceptive since, with his assumption of a constant interest rate, there are no aggregate capital gains, while capital gains in each open economy should be included fully. Here, the implications of Weitzman...

We describe a new approach to the problem of resolving distributional conflicts between an infinite and countable number of generations. We impose conditions on the social preferences that capture the following idea: If preference (or indifference) holds between truncated paths for infinitely...

Following Arrow et al. (2003), this paper considers green national accounting when population is changing and instantaneous well-being depends both on per capita consumption and population size. Welfare improvement is shown to be indicated by an expanded "genuine savings indicator", taking into...

This paper presents a distributional argument for the use of supply-side climate policies whereby carbon emissions are controlled through (i) depletion quotas or (ii) permanent confiscation of a fraction of the in situ carbon stocks. The modeling considers intertemporal competitive equilibria in...

This paper summarizes assumptions made and results obtained in parts of the literature on welfare and sustainability accounting. I consider five di®erent assumptions that can be imposed independently of each other, producing 32 di®erent combinations. This taxonomy is used to organize results...
