Consumption externalities and the effects of international income transfers on the global environment

In this paper, we extend the standard model of private provision of public goods by including consumption externalities to characterize a situation in which economic activities pollute the environment. We consider a case in which there are an industrial country which can afford to invest in the environment and a developing country which cannot. Then, we show that international income transfers in both directions can improve the global environmental quality as well as the welfare of each country. We also show that the results have important implications for policies such as official development assistance or the assignment of tradable emission permits.
