The traditional theory of comparative advantage has not been well integrated with the theories of externalities and location. In this paper we develop a conceptual framework which undertakes such an integration at the firm and regional levels. We call this the General Equilibrium with Individual Spatial Heterogeneity and Externalities (GEISHE) model. We use the model to study the effect of spatial heterogeneity in emission intensity on the spatial distribution of production under a uniform emission standard. This model suggests that the introduction of an emission restriction can have differential effects on the spatial patterns of production, depending on local production intensity. We also present empirical analysis of intraprovincial movement of production for the Canadian dairy industry using 1996 and 2006 Census data. Ceteris paribus , areas that had higher dairy production intensities in 1996 also tended to experience higher declines in their dairy cow populations between 1996 and 2006, which is consistent with the GEISHE model. These results suggest that environmental pressure may change the patterns of comparative advantage within a supply managed industry, even if relocation of production across provincial boundaries is not permitted. Expression of environmental comparative advantages seems to be taking place within provinces.
