Effects of international climate policy for India: evidence from a national and global CGE model

Abstract

AbstractIn order to significantly reduce global carbon emissions, it is necessary also to control CO2 emissions in fast growing emerging economies such as India. The question is how the Indian economy would be affected by including the country in an international climate regime. In this analysis we soft-link a global and a single-country computable general equilibrium model in order to be able to capture distributional issues as well as international repercussions. We analyze different options of transferring revenues from domestic carbon taxes and international transfers to different household types and the effects of different assumptions on exchange rates on transfer payments. Our results show (i) that welfare effects can differ significantly for different household types, which is generally ignored in analyses with global models, and (ii) that these effects are significantly influenced by international price repercussions and by accounting for transfers from international permit sales which is generally ignored in single-country models.
