Abstract We study a dynamic social choice problem in which a sequence of committees must decide how to consume a... Read more

Recent work on collective intertemporal choice suggests that non-dictatorial social preferences are generically time inconsistent. We argue that this claim... Read more

In this paper, the authors’ treatment of uncertainty in environmental applications is motivated by two leading examples: climate change and biodiversity loss. They argue that in these cases uncertainty is sufficiently far-reaching that standard decision-making tools such as expected utility theory may no longer capture important aspects of our uncertainty preferences. Richer models of decision-making, which allow us to express lack of confidence in our information, may be more desirable. Read more

The authors of this paper study the question of how important it is to predict the distant future. Read more

Abstract Experts and the general public often perceive environmental problems differently. Moreover, regulatory responses to environmental issues often do not... Read more

Paper demonstrates the potential benefits of model confirmation exercises for policy applications, demonstrating that the economic growth model used by a prominent BC-IAM had little predictive power over the 20th century. Read more

Agents exhibit pure intergenerational altruism if they care not just about the consumption utility experienced by future generations, but about... Read more

We study collective choice when individuals have heterogeneous discounted utilitarian preferences. Two attractive properties of intertemporal preferences are indistinguishable for... Read more

This paper explores the relationship between beliefs and policy choices in relation to environmental regulation. Read more

Climate change is fundamentally an `out-of-sample’ problem – our available information does not tightly constrain predictions of the consequences of... Read more

Intertemporal conflicts occur when a group of agents with heterogeneous time preferences must make a collective decision about how to... Read more

We model how heterogeneous beliefs about the uncertain consequences of long-run policy choices affect the incentives of incumbent governments. Read more

Stratospheric injection of sulphate aerosols has been advocated as an emergency geoengineering measure to tackle dangerous climate change, or as a stop-gap until atmospheric carbon dioxide levels are reduced. But it may not prove to be the game-changer that some imagine. Read more

Proceedings of the National Academy of Sciences of the USA. Disagreements about the value of the utility discount rate—the rate at which our concern for the welfare of future people declines with their distance from us in time—are at the heart of the debate about the appropriate intensity of climate policy.

Journal of Environmental Economics and Management. Recent theoretical work in the economics of climate change has suggested that climate policy is highly sensitive to ‘fat-tailed’ risks of catastrophic outcomes (Weitzman, 2009). Read more
