Environmental Regulations, Producer Responses, and ...

This paper derives a production analysis framework for modeling secondary benefits from environmental regulation, i.e. induced changes in yet unregulated pollutants. We emphasize the various ways in which the producers can respond to environmental regulations, and evaluate them in terms of their costs and their generation of secondary benefits. An application on the …
