We study the role of alternative intertemporal preference representations in a model of economic growth, stock pollutant and endogenous risk of catastrophic collapse. We contrast the traditional "discounted utility" model, which assumes risk neutrality with respect to intertemporal utility, with...

The paper investigates a climate-economy model with an iso-elastic welfare function in which one parameter gamma measures relative risk-aversion and a distinct parameter rho measures resistance to intertemporal substitution. We show both theoretically and numerically that climate policy responds...

We explore different possible definitions for conditional Choquet integrals and their implications for updating capacities. Many recent works consider relaxing dynamic consistency within Choquet Expected Utility models, but all of them deal with models where time is not explicitly introduced. We...

We assume a population of in nitely-lived households of the economy split into two groups : one with a high discount factor (the patient) and one with a low one (the impatient). The environmental quality is deteriorated by rm's polluting emissions. The governmen tal policy consists in proposing...

Policymakers have good reasons to prefer capital-based policies - such as CAFE standards or feebates programs - over a carbon price. A carbon price minimizes the discounted cost of a climate policy, but may result in existing capital being under-utilized or scrapped before its scheduled...

This paper analyzes the double dividend and distributional issues within an overlapping generations models framework with involuntary unemployment. We characterize the necessary conditions for the obtention of a double dividend when the revenue of the environmental tax is recycled by a variation...
