Network analysis has been applied to identify systemically important financial institutions after the 2008 financial crisis. Such applications have stressed the importance of centrality within the too-connected-to-fail concept. Yet, despite their well-known importance for financial stability,...

Since correlation may be interpreted as a measure of the influence across time-series, it may be conveniently mapped into a distance and into a weighted adjacency matrix. Based on such matrix, network theory has attempted to filter out the noise in correlation matrices by extracting the dominant...

Este documento expone cómo se conforma y articula el mercado OTC de valores en el caso colombiano. Así mismo, en el marco del mercado de deuda pública local, con base en el análisis de redes complejas, este documento describe, caracteriza y compara al mercado OTC con los organizados (SEN y...

En el presente trabajo se muestra evidencia para rechazar la Hipótesis de Mercado Eficiente (HME) a través de la anomalía efecto día (day effect). Se utilizan dos aproximaciones: la primera, bajo el supuesto de normalidad, estima un modelo lineal que corrobora los hallazgos de estudios...
