What should be the West's top priority for climate-change policy? This article is a revised and updated version of my talk to the Potsdam Global Sustainability Symposium (which drafted the Potsdam Declaration presented to the 2007 UN Climate Change Conference in Bali).

There is a large consensus among international institutions and national governments to favor urban-containment policies - the compact city - as a way to improve the ecological performance of the urban system.

This paper examines future energy and emissions scenarios in China generated by the Integrated Assessment Model WITCH. A Business-as-Usual scenario is compared with five scenarios in which Greenhouse Gases emissions are taxed, at different levels. The elasticity of China’s emissions is...

Traditional analyses of standards in international trade identify standards as government regulations and investigate the potential for distortion of trade flows. In reality, however, private industry groups exercise critical influence on the determination of technical standards. The composition...

The US Corporate Average Fuel Economy (CAFE) regulation mandates, subject to a civil penalty, producers to achieve a certain fleet average fuel economy on sales of new passenger cars. Analysing the incentive effects of CAFE, we find that it affords differential tax treatment to car models with...

This paper examines the role of liability for past environmental contamination in the privatization processes of Central and Eastern Europe. The theoretical section establishes a link between a risk-averse investor’s amount of information regarding the extent of past environmental...

The objective of this paper is to develop an analytical framework for estimation of the parameters of a structural model of an incentive contract under moral hazard, taking into account agents heterogeneity in preferences. We show that allowing the principal to strategically distribute the...
