North-South Trade and Industry-Specific Pollutants

Discussion Papers

In this paper, we examine the Pollution Haven Hypothesis (PHH) for the case inwhich every industry emits an industry-specific pollutant. When pollution intensities for individual pollutants are measured in terms of elasticity, there appears a clear trade pattern of the PHH. Developing countries export pollution-intensive goods while developed countries export less pollution-intensive goods. However, pollutants that are harmful to consumers may increase in either country as a result of trade liberalization. This suggests that in empirical studies, simple inclusion of harmfulness of pollutants in construction of a pollution intensity measure may mislead the result. We also find that consumers in different countries may exhibit different rankings of detestable pollutants, even though they have identical utility functions. Thus when international policy recommendations are made regarding how to set priorities among pollutants to be regulated, the experience of one country may not simply be applied to other countries.
