We consider whether pollution-intensive FDI tends to outflow from a country which maintains stringent environmental regulations and into countries with weak environmental regulations. We consider this issue by incorporating the predictions from the recent heterogeneous firm models of international trade into an empirical model of outward FDI by UK firms. We find that environmental regulations a...

The opening of new markets or trade routes has resulted in the deliberate or accidental introduction of new species, while the growth in the volume of trade has increased the frequency of species introductions. We model the connection between landscape heterogeneity, resource extraction, the level of biodiversity, and the level of trade. We show that the invasion risks of trade reduce the socia...

Fiscal instruments are potentially among the most effective, and cost-effective, options for addressing externalities related to poor air quality, urban road congestion, and greenhouse gases. This paper takes a case study, focused on Mauritius (a pioneer in the use of green taxes) to illustrate how existing taxes, especially on fuels and vehicles, could be reformed to better address these exter...

This paper introduces endogenous and directed technical change in a growth model with environmental constraints. The final good is produced from "dirty" and "clean" inputs. We show that: (i) when inputs are sufficiently substitutable, sustainable growth can be achieved with temporary taxes/subsidies that redirect innovation toward clean inputs; (ii) optimal policy involves both "carbon taxes" a...

Sea level rise will cause spatial shifts in economic activity over the next 200 years. Using a spatially disaggregated, dynamic model of world economy, this paper estimates consequences probabilistic projections local sea changes. Under an intermediate scenario greenhouse gas emissions, permanent flooding is projected to reduce global real GDP by 0.19 percent present value terms. By year 2200, ...
