Resumen de Climate and international trade policies when emissions affect production possibilities

Christos Kotsogiannis, Alan Woodland

• In this paper, we develop a model of international trade and climate change in which emission discharges arising from production have a feedback effect on national production sectors by impacting upon effective factor endowments. With this context, the objectives are, first, to provide a general characterization of Pareto-efficient climate and trade policies and, second, to examine the possibility � starting from non-Pareto-efficient equilibria � for Pareto-improving environmental policies. We provide conditions under which several particular reforms of carbon taxes are welfare improving.
