We study the regulation of a morally responsible agent in the context of a negative consumption externality and motivation crowding. In particular, we analyze how various governmental interventions affect the agent's motivation to assume moral responsibility. Employing a motivation-crowding...

Mit der Einführung des europäischen Emissionshandelssystems kommt es zwangs-läufig zu einer Überschneidung der Regelungsbereiche mit der in Deutschland be-reits existierenden Ökosteuer. In diesem Artikel wird diskutiert, inwieweit durch die direkte und indirekte Interaktion beider...

Starting in 2005, the EU will implement a CO2 emissions trading scheme. In this paper we show that the outspoken goals of economic efficiency and free allocation of allowances are incompatible with harmonized allocation rules. In general, the assignment of allowances is endogenous and differs...

This article provides a review of economic studies analyzing the use of multiple policies - a socalled policy mix - to cope with single pollution problems. To guide and structure the review, an analytical framework is developed and applied. The framework integrates transaction costs into the...

The combination of emissions trading and emissions taxes is usually rejected as redundant or inefficient. This conclusion is based on the restrictive assumption that both policies are exclusively meant to control pollution. However, particularly taxes may pursue a variety of other policy...

Based on a case study on Bombay, we argue that urban infrastructure, like the sewage system and the municipal waste collection, is an important instrument for urban environmental policy. We develop a spatial general equilibrium model of a monocentric city, where infrastructure serves as a public...

International offset certificates have systematically traded at a lower price than European Union Allowances (EUAs), although they are perfect substitutes. Firms therefore had a strong incentive to use the cheaper certificates up to the maximum quantity fixed by the regulator. This study...

Climate policies overlapping a cap-and-trade scheme are generally considered not to change domestic emissions. In a two-sector general equilibrium model where only one sector is covered by a cap, we find that such policies do have a net impact on carbon emissions through inter-sectoral leakage....

This paper develops an analytical framework for studying the Baumol-Oates efficiency of traditional single instrument abatement policies vis-a-vis green defaults in the face of price inertia and deliberate defaulting of subpopulations. In this special case of behavioural heterogeneity command...

Putting a price on carbon is considered a crucial step for China's endeavor of harnessing the market forces to reduce its energy consumption and carbon emissions. Indeed, aligned with China's grand experiment with low-carbon provinces and low-carbon cities in six provinces and thirty-six cities,...
