International Trade in Oil, Gas and Carbon Emission Rights: An Intertemporal General Equilibrium Model

This paper employs a five-region intertemporal model to examine three issues related to carbon emission restrictions. First, we investigate the possible impact of such limits upon future oil prices. We show that carbon limits are likely to differ in their near- and long-term impact. Second, we analyze the problem of "leakage" which could arise if the OECD countries were to adopt unilateral limits upon carbon emissions. Third, we quantify some of the gainsfrom trade in carbon emission rights. Each of these issues have been studied before, but to our knowledge this is the first study based on a multi-regional, forward-looking model. We show that sequential joint maximization can be an effective way to compute equilibria for intertemporal general equilibrium models of international trade.
