Abstract
Este documento tiene como propósito diseñar un mecanismo que permita explicar los esquemas colusorios que potencialmente pueden presentarse en una licitación para proyectos de obras en Colombia. Para el efecto, se toma una licitación estándar en Colombia en temas de concesión vial y siguiendo la propuesta metodológica de Harsanyi (1963), se utilizan funciones de mejor respuesta para que los entes coludidos definan sus estrategias cuando la propuesta de un tercer agente no coludido sea perfectamente previsible. También se estudia la estrategia de este cartel cuando se presentan más de tres licitantes. Al final, se enumeran algunas recomendaciones para reducir la formación de carteles en licitaciones.
This paper is intended to design a framework that allows explaining the collusive that can arise in some types of public procurement processes that imply construction works in Colombia. For that purpose, a standard Colombian public procurement process for road works is taken as the base and, using a Harsanyi framework, best response functions are used in order to define the strategies of the colluded firms when facing competition from another non-colluded firm, whose offer will be perfectly foreseeable. The strategy of the cartel when facing more than one non-colluded firms is also studied. At the end, some recommendations to hinder the formation of these cartels are listed.
