Gestión de las empresas prestadoras del servicio de alcantarillado: un análisis de caso

Abstract

In this article is shown a descriptive, casual, correlational and analytical study of management for the companies that provides the sewerage service in the cities; Bogota and Cartagena, Acueducto y Alcantarillado de Bogota (Aqueduct and Sewerage of Bogota) –EAAB-, and Aguas de Cartagena (Waters of Cartagena) –Acuacar, Respectively. It has been taken as theoretical referents: the institutions analyzed by North, Urrutia, Robinson and Acemoglu; the organization theory by Williamson; the analysis of the value chain by Michael Porter; and the economies of scale generated for productive clusters studied by Cuervo and González. While Bogota’s coverage is up to 100%, in Cartagena the coverage is 87.93%, it is used the model of the Cost and expenses simplified to analyze the company’s strategic management plan and to identify the strategies used in each city to improve the coverage level. In addition it is determined, which is the variable with high impact over the coverage with the Ordinary Least squares method (OLS) LOG-LOG, using monthly data from 2003 until 2011. In conclusion, it has been found that the variables with high impact over the coverage in Bogota and Cartagena are the population density, total value billed and the total given subsidy. However in Bogota, the use of expenses and administrative cost and the per capita investment in infrastructure are also significant and explicative variables related with the coverage level reached in this city.
