We investigate the Hartwick rule for saving of a nation necessary to sustain a constant level of private consumption for a small open economy with an exhaustible stock of natural resources. The amount by which a country saves and invests less than the marginal resource rents equals the expected...

Many resource-rich countries have poor economic performance and suffer from negative genuine saving rates, especially if they have many rival factions and badly functioning legal systems. We attempt to shed light on these stylized facts by analyzing a power struggle about the control of natural...

This paper examines the role of the burden of proof (BoP) in National Treatment (NT) disputes under trade agreements. In the situation under study, imports may cause environmental damage, in which case less favorable treatment of imported products may be globally desirable from an international...

This paper develops a model of trade and CO2 emissions with heterogenous firms, where firms make abatement investments and thereby have an impact on their level of emissions. The model shows that investments in abatements are positively related to firm productivity and firm exports. Emission...

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).

Combining unique data bases on emissions with sectoral output and employment data, we study the sources of the fall in world-wide SO2 emissions and estimate the impact of trade on emissions. Contrarily to concerns raised by environmentalists, an emission-decomposition exercise shows that scale...

The outcome of the 15th conference of the Parties to the UNFCC showed a shift from a top-down approach with a collective target favoring environmental objectives to a bottom-up accord favoring political feasibility with no meaningful binding agreement in sight as the global climate regime and...

The latest round of international negotiations in Copenhagen led to a set of commitments on emission reduction which are unlikely to stabilise global warming below or around 2°C. As a consequence, in the absence of additional ambitious policy measures, adaptation will be needed to address...

We study the determinants of comparative advantage in polluting industries. We combine data on environmental policy at the country level with data on pollution intensity at the industry level to show that countries with laxer environmental regulation have a comparative advantage in polluting...

This paper discusses the state of knowledge about the trade-related environmental consequences of a country’s development strategy along three channels: (i) direct trade-environment linkages (overexploitation of natural resources and trade-related transport costs);(ii) ‘virtual trade’ in...
