The paper clarifies the link between changes in risk aversion and the effect on the consumption discount rate. In a general framework that can cope with various forms of uncertainty, it is shown that the response of the consumption discount rate to a change in risk aversion depends on some...

The Stern/Nordhaus controversy has polarized the widely disparate beliefs about what to do in order to tackle the climate challenge. To explain differences in results and policy recommendations, comments following the publication of the Stern Review have mainly focused on the role played by the...

In this paper we use Pindyck’s model (2002) to show that the discount rate may play an important role in explaining for the income-pollution pattern observed in the real world. Low levels of income involve high values of discount rate, that are obstacles to the adoption of a pollution...

Cost-benefit analyses require comparing costs and benefits that occur at different points in time. Doing so, however, creates conflicts between short-term considerations — a discounting scheme has to be consistent with observed behaviours — and long-term ethical issues — a discounting...

This paper addresses the conditions for setting up strict civil liability schemes. For that it compares the social efficiency of two main civil liability regimes usually enforced to protect the environment: the strict liability regime and the “capped strict liability scheme”. First, it shows...

This paper studies the delegation of activities that pose serious risks to health and the environment in an economy regulated by strict liability schemes. Strict liability induces judgment-proof possibilities. Two civil liability regimes are then compared: a strict liability scheme and a capped...
