Over the last few decades, state and local governments increasingly have adopted tax and other policies to encourage economic development within their borders. These programs have recently come under attack as potentially inconsistent with the U.S. Supreme Court's dormant Commerce Clause jurisprudence. In an opinion issued in late 2004, the Sixth Circuit Court of Appeals invalidated Ohio's investment tax credit, contending that it discriminates against interstate commerce. The U.S. Supreme Court has granted certiorari in the case. In the meantime, similar litigation is underway in other states. In reaction to these developments, legislation has been introduced in Congress to protect the right of states to provide tax incentives. To shed light on the issues involved in these ongoing controversies, we offer an introduction to existing research concerning the economic effects of state tax incentives. There is a voluminous literature concerning the efficacy of state business subsidies. Surprisingly, however, very few econometric studies have examined the multistate impact of tax credits for physical investment (for example, the investment tax credit) or research and development (R&D tax credits). This focus may be due in part to the fact that, up until now, the issue was primarily one for state and local policymakers. Yet the interstate economic effects have significance for the Commerce Clause analysis of state tax incentives. Our goal is to provide a general introduction to these issues and to shed some light on the complexities involved in evaluating interstate economic effects.
