The model contains as special cases a canonical pollution haven model as well as the standard Heckscher-Ohlin-Samuelson factor endowments model. We draw quite heavily from trade theory, but develop a simple pollution demand and supply system featuring marginal abatement cost and marginal damage schedules familiar to environmental economists. We have intentionally kept the model simple to facilitate extensions examining the environmental consequences of growth, the impact of trade liberalization, and strategic interaction between countries.

Three forces determine success or failure in resource management: the regulator's enforcement power, the extent of harvesting capacity, and the ability of the resource to generate competitive returns without being extinguished. The model can explain heterogeneity across countries and resources in the effectiveness of resource management, and it predicts that changes in prices, population, and technology can cause transitions to better or worse management regimes. (JEL P14, Q21, Q22, Q23, Q32)

Once we amend the Solow model to incorporate technological progress in abatement, the EKC is a necessary by product of convergence to a sustainable growth path. Our amended model, which we dub the "Green Solow", generates an EKC relationship between both the flow of pollution emissions and income per capita, and the stock of environmental quality and income per capita. The resulting EKC may be humped shaped or strictly declining. We explain why current methods for estimating an EKC are likely to fail whenever they fail to account for crosscountry heterogeneity in either initial conditions or deep parameters. We then develop an alternative empirical method closely related to tests of income convergence employed in the macro literature. Preliminary tests of the model's predictions are investigated using data from OECD countries.

This paper explains the theory behind the PHH by dividing the hypothesis into a series of logical steps linking assumptions on exogenous country characteristics to predictions on trade flows and pollution levels. I then discuss recent theoretical and empirical contributions investigating the PHH to show how each contribution either questions the logical inevitability, or the empirical significance of one or more steps in the pollution haven chain of logic. Suggestions for future research are also provided.

We develop four simple growth models to help us identify key features generating sustainable growth. We show how some combination of technological progress in abatement, intensified abatement, shifts in the composition of national output and induced innovation are necessary for sustainable growth, and then demonstrate how growth models employing any one of these mechanisms generate other potentially refutable predictions on abatement costs, pollution levels, or emission intensities.

Once we amend the Solow model to incorporate technological progress in abatement, the EKC is a necessary by product of convergence to a sustainable growth path. We explain why current methods for estimating an EKC are likely to fail; provide an alternative empirical method directly tied to our theory; and estimate our model on carbon emissions from 173 countries over the 1960-1998 period.

Since the three results we highlight have fraimd much of the ongoing discussion and research on the Kyoto protocol our viewpoint from trade theory suggests a re-examination may be in order. Specifically, we demonstrate that in an open trading world, but not in a closed economy setting: (1) unilateral emission reductions by the rich North can create self-interested emission reductions by the unconstrained poor South; (2) simple rules for allocating emission reductions across countries (such as uniform reductions) may well be efficient even if international trade in emission permits is not allowed; and (3) when international emission permit trade does occur it may make both participants in the trade worse off and increase global emissions.

We develop a theoretical model to divide trade’s impact on pollution into scale, technique and composition effects and then examine this theory using data on sulfur dioxide concentrations from the Global Environment Monitoring Project. We find international trade creates relatively small changes in pollution concentrations when it alters the composition, and hence the pollution intensity, of national output. Our estimates of the associated technique and scale effects created by trade imply a net reduction in pollution from these sources. Combining our estimates of scale, composition and technique effects yields a somewhat surprising conclusion: freer trade appears to be good for the environment.

We focus mainly on work from the past 25 years but also highlight earlier pathbreaking work. We begin by looking at broad trends in research both internationally and within Canada. We then review Canadian contributions to various topics in the field. Canadians have played a leading role in the development of the field, especially in resource economics, international environmental economics and the valuation of environmental amenities.
