In this paper we study the impact of regulatory complexity, a measure of institutional quality, on the GDP, on per capita income and on the growth rate of the Italian regions. For comparative reasons we also use the duration of civil disputes as a further indicator of institutional quality used in the regressions as an alternative to the indicator of regulatory complexity. From the theoretical point of view, we use the approach of negative co‐ordination externalities, among the four sources of regulatory production that are at work at the same time. Our approach may be applied in all the countries with a multi‐level government system. Using the random effects and quantile regressions models we are able to quantify the effects of an improvement in institutional quality on the GDP and the growth rate, making a comparison between the results obtained using regulatory complexity or the duration of civil disputes as covariates. We also check for spatial dependence among variables. Econometric analysis supports the theoretical assumption that regulatory complexity is an impediment to the growth of regional GDP and per capita income. The main finding of our analysis is that a reduction in regulatory complexity would be more effective than a reduction in the duration of civil disputes in increasing the income and growth rate. This result could be useful for the policy‐maker because by reducing regulatory complexity we may obtain a considerable by‐product in the shorter duration of civil disputes. [ABSTRACT FROM AUTHOR]

Urban sprawl has evolved into an exceptionally complex public policy problem in the United States over the course of recent decades. One factor that has made it particularly difficult to deal with is its relationship to the fragmented structure of the American system of land use governance. Acting on behalf of their residents, local governments enact land use regulations to secure lifestyle preferences for low density, suburban living environments while at the same time ensuring a high quality of public service provision. This article examines the effect of this process on metropolitan spatial structure through a series of econometric models designed to test the following hypothesis: that fragmentation promotes sprawl by increasing the proportion of growth that occurs at the unincorporated urban fringe. The estimation results reveal substantive evidence that municipal fragmentation and several related factors - including special districts, infrastructure investments, and white flight processes - have a significant and enduring effect on the growth of outlying areas.
