Vehicle taxation based on CO2 emissions is increasingly being adopted worldwide in order to shift consumer purchases to low-carbon cars, yet little is known about the effectiveness and overall economic impact of these schemes. We focus on feebate schemes, which impose a fee on high-carbon...

Climate change mitigation programs classify two types of carbon offsets: Additional and non-additional. Additional offsets are offsets that correspond to actual reductions in emissions. In contrast, non-additional offsets are offsets that do not correspond to emissions reductions. These offsets...

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 approach overlooks a fundamental fact: what matters for the ecological outcome of...

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...

International markets for tradable emission permits (TEP) co-exist with national energy taxation. A firm trading emission permits in the international market also pays energy taxes in its host country, thus creating an interaction between the international TEP-market and national energy taxes....

This paper studies fiscal federalism when regions differ in voters’ ability to monitor public officials. We develop a model of political agency in which rent-seeking politicians provide public goods to win support from heterogeneously informed voters. In equilibrium, voter information...

We analyse the impact of micro-founded political institutions on environmental policy and economic growth. We model an overlapping-generations economy, where individuals differ in preferences over the environment (as well as in age). Labour taxation and capital taxation is used to finance a...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

Unilateral second-best carbon taxes are analysed in a two-period, two-country model with international trade in final goods, oil and bonds. Acceleration of global warming resulting from a future carbon tax is large if the price elasticities of oil demand are large and that of oil supply is...
