Enterprise zones have been part of American urban policy for over 20 years. In this book, the authors (urban and regional planning, the University of Iowa) use a hypothetical firm methodology to measure the value of enterprise zone incentives to business, involving construction of a set of financial statements for typical firms and application of tax code and incentives to those firms. They briefly discuss this model (with technical information on the model included in an appendix), and look at the results of enterprise zone programs in place in 13 states.

Peters and Fisher perform very detailed analysis on the effectiveness of the incentives used in enterprise zones and produce rather more discouraging findings on their effectiveness.

We take up two questions that have not been explored in research on enterprise zones. First, does a considerably longer-run perspective on the effects of state enterprise zones lead to different answers? And second, are there heterogeneous effects of enterprise zones that depend on the set of incentives these programs offer, which can vary widely? Our results indicate that whether we look at state enterprise zone programs through a longer-term lens, or through the lens of program heterogeneity, we generally do not find any consistent indication of beneficial effects of state enterprise zone programs, and if anything the longer-run effects are negative. The lack of positive effects is consistent with most of the prior evidence that focuses on effects that are short-term and homogeneous.
