Abstract

En este trabajo se propone una metodología para cuantificar la centralidad de los agentes que participan en el mercado interbancario, bajo un enfoque de juegos cooperativos. La metodología utiliza diferencias de valores de Shapley en juegos de transacciones con y sin restricciones de red observable, y permite construir series de tiempo para cada agente, que identifican la posición relativa de cada uno frente al mercado. Por último, se analizan propiedades del indicador y su relación con variables relacionadas con riesgo de liquidez. Se encuentra que para el caso del SEN hay una relación entre un indicador de dispersión de red y los bid-ask spread de los TES en bandas líquidas.
