We model a dynamic monopoly with environmental externalities,investigating the adoption of a tax levied on the firm's instantaneous contribution to the accumulation of pollution. The latter process is subject to a shock, which is i.i.d. across instants. We prove the existence of an optimal tax...

This paper develops an analytical framework for studying the Baumol-Oates efficiency of traditional single instrument abatementpolicies vis-à-vis green defaults in the face of price inertia and deliberate defaultingby subpopulations. In this special case ofbehavioural heterogeneity, command and...

We develop a model of optimal carbon taxation and redistribution taking into account horizontal equity concerns by considering heterogeneous energy efficiencies. By deriving first- and second-best rules for policy instruments including carbon taxes, transfers and energy subsidies, we then...

We study the introduction of new technologies when their costs are subject to idiosyncratic uncertainty and can only be fully learned through individual experience. We set up a dynamic model of clean experience goods that replace old polluting consumption options and show how optimal regulation...

This paper explores the insurmountable challenges facing orthodox economic approaches to assessing climate control as if it were a matter of weighing-up the costs of money spent to benefits as the returns on an investment. Such am appraisal method borrows form project appraisal for financial...

A basic tenet of economics posits that when consumers or firms don't face the true social cost of their actions, market outcomes are inefficient. In the case of negative externalities, Pigouvian taxes are one way to correct this market failure, where the optimal tax leads agents to internalize...

This essay revisits the question of instrument choice for the regulation of externalities in the context of climate change. The central point is that the Pigouvian prescription to equate marginal control costs with the expected marginal benefits of damage reduction should guide the design of...
