International emissions trading and the distribution of capital

This paper compares two regimes of tradable emission permits, a regime with international permit trade (IPT) and a regime with domestic permit trade (DPT). We focus on the effects of the distribution of firms between countries. Our model combines intra-industry trade with a monopolistically competitive industry. We find that a more equal distribution of firms between countries results in higher global pollution under the DPT regime, while under the IPT regime the global pollution is invariant with the distribution of firms. We also find that international permit trade can either increase or reduce global pollution, depending on the distribution of firms.
