This book offers cross-national evidence of the effectiveness of financial and physical incentives for regional development. It challenges the traditional wisdom that competition is harmful for regional development or can be zero-sum. It answers questions such as: What are the effects of tax incentives on the rest of the economy? Do such incentives merely redistribute employment? Do tax and infrastructure incentives have any effect on the unemployment rate of areas adopting them?It takes a labour market perspective to benefits from regional development. It reports some evidence of how much Americans are willing to take home as pay, given certain characteristics. Further, it reports findings regarding the effectiveness of regional development policies in India, firms' location decisions, and their contribution to communities where they locate, based on quantitative and qualitative evidence.
