The Ramsey rule for the consumption rate of discount assumes a transfer of money of a (representative) agent at one point in time to the same agent at another point in time. Climate policy (implicitly) transfers money not just over time but also between agents. I propose three alternative...

Uncertainty plays a significant role in evaluating climate policy, and fattailed uncertainty may dominate policy advice. Should we make our utmost effort to prevent the arbitrarily large impacts of climate change under deep uncertainty? In order to answer to this question we propose an new way...

This paper investigates the economic implications of a comprehensive approach to sustainable greenhouse policies that strives to stabilise the atmospheric concentration of the five major greenhouse gases at an ecologically determined threshold level. In a theoretical optimisation model...

Recent contributions have questioned whether biofuels policies actually lead to emissions reductions, and thus lower climate costs. In this paper we make two contributions to the literature. First, we study the market effects of a renewable fuel standard. Opposed to most previous studies we...

This paper provides an overview of the U.S. experience with market-based instruments with four categories: emission charges, tradeable permit systems,market friction reduction, and government subsidy reduction. Following that, I examine normative lessons that can be learned from these...

Environmental policies typically combine the identification of a goal with some means to achieve that goal. This chapter for the forthcoming Handbook of Environmental Economics focuses exclusively on the second component, the means - the "instruments" - of environmental policy, and considers, in...

This study develops a theoretical general equilibrium model to examine optimal externality tax policy in the presence of externalities linked to one another through markets rather than technical production relationships. Analytical results reveal that the second-best externality tax rate may be...

Die globale Erwärmung und die daraus resultierenden ökonomischen und sozialen Konsequenzen sind eng verbunden mit dem Ausstoß von Treibhausgasen. Dem Kyoto-Protokoll nach ist die Europäische Union verpflichtet, die Emissionen dieser Gase bis zum Zeitraum 2008/2012 um 8% gegenüber 1990 zu...
