We study how fuel price changes affect cost-minimizing choices by airlines that have implications for the extent of this externality. The airline industry's capital stock can be easily inventoried as a set of long-lived, durable aircraft. This portfolio approach allows us to study the utilization and composition of the capital stock at a highly disaggregated level. Changes in airline operations directed toward conserving fuel can be an important path toward lower emissions.}, keywords={carbon dioxide emissions;energy conservation;airline fuel consumption}, }
