Research in Spatial Economics (RISE)
URI permanente para esta comunidad
In our group we develop quantitative methods for spatial analysis that allow researchers, public and private institutions to attain a better understanding of their georeferenced data. Our methodologies are characterized by their multidisciplinarity, involving research domains such as operation research, econometrics and exploratory spatial data analysis.

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.

Evidence for Colombia(ELSEVIER SCIENCE SA, 2010-11-01) Ramos, Raul; Duque, Juan C.; Surinach, Jordi; Universidad EAFIT. Departamento de Economía y Finanzas; Research in Spatial Economics (RISE)Using microdata from the 2002-2006 Colombian Continuous Household Survey, we find an elasticity of individual wages to local unemployment rates of - 0.07. However, the elasticity for informal workers is significantly higher, a result which is consistent with efficiency wage theoretical models and relevant for regional labour market analysis in developing countries. © 2010 Elsevier B.V.Ítem Una aplicación con datos de sobrevivencia: Utilización de modelos de regresión parcial censurados(Fondo Editorial Universidad EAFIT, 2010-12-31) Velasquez, Hermilson; Héctor Javier Herrera; Jorge Ivan Jimenez Gomez; Universidad EAFIT.

Departamento de Economía y Finanzas; Research in Spatial Economics (RISE)The p-regions problem involves the aggregation or clustering of n small areas into p spatially contiguous regions while optimizing some criteria. The main objective of this article is to explore possible avenues for formulating this problem as a mixed integer-programming (MIP) problem. The critical issue in formulating this problem is to ensure that each region is a spatially contiguous cluster of small areas. We introduce three MIP models for solving the p regions problem. Each model minimizes the sum of dissimilarities between all pairs of areas within each region while guaranteeing contiguity. Three strategies designed to ensure contiguity are presented: (1) an adaptation of the Miller, Tucker, and Zemlin tour-breaking constraints developed for the traveling salesman problem; (2) the use of ordered-area assignment variables based upon an extension of an approach by Cova and Church for the geographical site design problem; and (3) the use of flow constraints based upon an extension of work by Shirabe. We test the efficacy of each formulation as well as specify a strategy to reduce overall problem size. © 2011 The Ohio State University.Ítem Research networks and scientific production in Economics: The recent Spanish Experience(Universidad EAFIT, 2011-03-01) Duque, J, C.; Ramos, Raul; Rayuela, Vicente; Universidad EAFIT.

Departamento de Economía y Finanzas; Research in Spatial Economics (RISE)In this paper, we present an efficiency improvement for the algorithm called AMOEBA, A Multidirectional Optimum Ecotope-Based Algorithm, devised by Aldstadt and Getis (Geogr Anal 38(4):327-343, 2006). AMOEBA embeds a local spatial autocorrelation statistic in an iterative procedure in order to identify spatial clusters (ecotopes) of related spatial units. We provide an analysis of the computational complexity of the original AMOEBA and develop an alternative formulation that reduces computational time without losing optimality. Empirical evidence is provided using georeferenced socio-demographic data in Accra, Ghana. © 2010 Springer-Verlag.Ítem A Stepwise Procedure to Determinate a Suitable Scale for the Spatial Delimitation of Urban Slums(2012-01-01) Duque, Juan CarlosÍtem A stepwise procedure to determinate a suitable scale for the spatial delimitation of urban slums(SPRINGER, 2012-01-01) Duque JC; Royuela, Vicente; Noreña, Miguel
