“…In this regard, the Gini index has traditionally been used for analyzing spatial location patterns of manufacturing industries (KRUGMAN, 1991;AMITI, 1999;BRÜLHART, 2001;SUEDEKUM, 2006, inter alia). More recently, the generalized entropy family of indexes (GE, henceforth) has been used as well because of its advantages in terms of decomposability (BRÜLHART and TRAEGER, 2005;BRAKMAN et al, 2005;PÉREZ-XIMÉNEZ and SANZ-GRACIA, 2007;CUTRINI, 2009). The properties of the inequality measures on which these concentration indexes are based are well known because the literature on income distribution has dealt with inequality from an axiomatic perspective; however, the corresponding geographical concentration measures are being applied without explicitly stating the consequences of using them.…”
