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...

In this paper, we view health insurance as a combined hedge against the two consequences of falling ill: treatment expenditures and loss in income. We discuss how an individual’s ability when healthy affects her decision on whether to buy health insurance with treatment to full recovery if ill...

This paper provides two conditions of epistemic robustness, robustness to alternative best replies and robustness to non-best replies, and uses them to characterize variants of curb sets in finite games, including the set of rationalizable strategies.

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...

Following Arrow et al. (2003), this paper considers green national accounting when population is changing and instantaneous well-being depends not only on per capita consumption, but also population size. It is shown that welfare improvement can be indicated by an expanded “genuine savings...
