El mercado interbancario juega un papel muy importante como distribuidor de recursos líquidos. No obstante, si muchas entidades enfrentan simultáneamente problemas de liquidez, la oferta agregada de liquidez sería menor que la demanda y los bancos estarían obligados a acudir al banco central...

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,...

Levels of interest rates below historical norms may have enhanced financial instability in developed and developing economies during the 2000's. The risk taking channel of monetary policy transmission is a recent theory that explains the interaction between risk perceptions of the financial...
