We argue that anti-density zoning increases black residential segregation in U.S. metropolitan areas by reducing the quantity of affordable housing in white jurisdictions. Drawing on census data and local regulation indicators compiled by Pendall, we estimate a series of regression models to measure the effect of maximum density zoning on black segregation. Results estimated using ordinary leas...

The idea is to extract some knowledge from the confusion matrices in order to make the zoning process less 21 empirical. The feature set considered in this work is based on concavities/convexities deficiencies, which are obtained by labeling the b...
