THE EFFICIENCY OF ENTERPRISE ZONE PROGRAMS SOME CONFLICTING RESULTS?

We propose in this paper a critical review of the literature on urban enterprise zones. The results that emerge from the papers published over the last twenty years vary a lot across studies. Several explanations can account for these apparently conflicting results. Technical tools and empirical methods for the evaluation of such policies have greatly improved since the 1990’s. Moreover, it seems that the efficiency of urban enterprise zones depends on zone characteristics, industrial sector and policy design. Further research in this area should try to better take into account general equilibrium effects, in order to provide a more accurate measure of the welfare implications of these policies.
