Abstract

China has promised large cuts in CO2 emissions by 2020, which is likely to have differential effects across regions. We know little about the regional effects of pollution reduction. We make a contribution to filling this gap using a small theoretical model with two regions, features of the Chinese economy and the right to emit CO2 as a factor of production. We find regionally differentiated effects on income, welfare and output and explore government policies designed to reduce these effects. The effects of fiscal policies depend crucially on whether one or both regions respond and on whether output or welfare is targeted. Boosts to productive capacity do better in terms of output but not welfare.

Resumen

China ha prometido grandes recortes en las emisiones de CO2 en 2020, lo que es probable que tenga efectos diferentes en las distintas regiones. Se sabe poco acerca de los efectos regionales de la reducción de la contaminación. Contribuimos aquí a cerrar esta brecha con un pequeño modelo teórico que utiliza dos regiones, las características de la economía China y el derecho a emitir CO2 como un factor de producción. Encontramos efectos diferenciados por regiones sobre la renta, el bienestar y la producción, y exploramos las políticas gubernamentales destinadas a reducir estos efectos. Los efectos de las políticas fiscales dependen de manera crucial de si responden una o ambas regiones, y de si se dirigen hacia la producción o hacia el bienestar. Las mejoras en la capacidad productiva resultan mejor en términos de producción, pero no en cuanto a bienestar.
