Carbon leakage provides an efficiency argument for unilateral climate policy to differentiate emission prices in favor of emission-intensive and trade-exposed sectors. At the same time, differential emission pricing can be (mis-)used as a beggar-thy-neighbor policy to exploit terms of trade....

In the absence of effective world-wide cooperation to curb global warming, import tariffs on embodied carbon have been proposed as a potential supplement to unilateral emissions pricing. We consider alternative designs for such tariffs, and analyze their effects on global welfare within a...

Political feasibility of emission trading systems may crucially depend on the free initial allocation of emission allowances to energy-intensive industries in order to ameliorate adverse production and employment effects. We investigate the potential trade-off between such compensation and...

In a world where the prospects of a global agreement to control greenhouse gas emissions are bleak, the idea of using trade policy as an implicit regulation of foreign emission sources has gained many supporters in countries contemplating unilateral climate policies. Embodied carbon tariffs tax...

We study the effects of greenhouse gas emissions on optimum growth and environmental policy by using an expansion-in-varieties growth model with polluting non-renewable resources. Climate change harms the capital stock. Our main contribution is to introduce and extensively explore the naturally...
