(2010) Trade, Population growth, and the Environment in Developing Countries. Journal of Population Economics 23: 1351-1370 (co-authored with Ulla Lehmijoki)

We examine pollution in a developing country where fertility is endogenous and wealth increases welfare through status. When the country has defective environmental laws, it has a comparative advantage in capital-intensive “dirty” goods. Gains from trade due to trade liberalization then increase income and boost population growth. With strong incentives to save, they also stimulate investment, which hampers population growth. Because population growth crowds out labor supply, production of capital-intensive dirty goods first increases and then decreases. This yields a typical environmental Kuznets path: pollution increases at the earlier stages but decreases at the later stages of development.
