An influential justification for placing responsibility for environmental regulation at the federal level is that otherwise states would engage in a socially undesirable "race to the bottom, " making their environmental standards too lax in an effort to attract and retain industry. After discussing the difficulties in empirically testing this theory, Professor Revesz shows that race-to-the-bottom arguments encounter no support in existing models of interurisdictional competition. He then establishes that even if there were a race to the bottom over environmental standards, federal regulation would not be an effective response: faced with strict federal environmental standards, states concerned with attracting industry would relax regulatory controls in other areas. Professor Revesz concludes by showing that in the corporate-charter and bank-charter literatures, the race-to-the-bottom label has been used to identify issues distinct from those implicated in the term in the environmental context, and he offers a conceptual typology that elucidates the relevant distinctions.
