Abstract

En este documento se utilizan herramientas de análisis de redes tradicionales para describir las características generales de la estructura del Mercado Electrónico Colombiano (MEC). Se encontró que éste está fuertemente concentrado en unos pocos agentes, con bajo nivel de conectividad, aunque con un alto grado de reciprocidad en las relaciones entre los agentes. Se calcularon indicadores de centralidad diaria para cada uno de aquéllos, buscando identificar cuáles son sistémicos según su posición relativa en la red. Este análisis permitió observar que en el MEC los agentes más grandes, los que tienen mayor número de conexiones, aquellos con mayor capacidad de intermediación, y los que tienen relaciones cercanas con agentes más importantes tienden a ser los mismos cada día. Finalmente, vía simulaciones, se buscó medir qué tan sensible es la estructura de red del MEC ante la ausencia de los agentes más conectados. Se encontró que la estructura es fuertemente dependiente de las conexiones de unos pocos agentes, que pueden clasificarse como centrales a la red.
