Estimating the impact of regional policy: A review of applied research methods

This paper provides a critical review of the methodological approaches that have been used to estimate the impacts of regional economic policies. A considerable variety of approaches are examined, ranging from questionnaire studies through single- and multiple-equation regression models to cost-benefits analysis, and attention is focused on the pros and cons of these approaches and the reliability of the impact assessments derived. The paper concludes with some suggestions for further research in this field.
