Ítem Identificação de clusters industriais na Colômbia baseados na teoria de grafos(Elsevier, 2009-01-01) Duque, J.C.; Rey, S.J.; Gómez, D.A.; Universidad EAFIT. Departamento de Economía y Finanzas; Research in Spatial Economics (RISE)This paper presents a new way to identify and understand the industry clusters in the Colombian economy. The analysis relies on a recent methodology proposed by Duque and Rey (2008) where intricate input-output linkages between industries are simplified using network analysis. In addition to other techniques for cluster identification available in the literature, this novel methodology allows us not only to classify each industry in a given cluster, but also to understand how industries are related to each other within their clusters. This methodology offers a conciliatory approach to two radically different views about the economic unit from which policy makers should design their strategies for resource allocation: Porter's cluster strategy versus Hausmann's industrial targeting.Ítem Identifying industry clusters in Colombia based on graph theory(Elsevier, 2009-01-01) Duque, J.C.; Rey, S.J.; Gómez, D.A.; Universidad EAFIT.

Departamento de Economía y Finanzas; Research in Spatial Economics (RISE)In this paper, we introduce a new spatially constrained clustering problem called the max-p-regions problem. It involves the clustering of a set of geographic areas into the maximum number of homogeneous regions such that the value of a spatially extensive regional attribute is above a predefined threshold value. We formulate the max-p-regions problem as a mixed integer programming (MIP) problem, and propose a heuristic solution. © 2011, Wiley Periodicals, Inc..
