In this paper, we study the empirical relationship between credit funding sources and the financial vulnerability of the Colombian banking system. We propose a statistical model to measure and predict banking-fragility episodes associated with credit funding sources classified into retail...

We study the network of Colombian sovereign securities settlements. With data from the settlement market infrastructure we study financial institutions’ transactions from three different trading and registering individual networks that we combine into a multi-layer network. Examining this...

La existencia de memoria de largo plazo en las series financieras implica que los retornos de un activo hoy pueden tener incidencia sobre los retornos futuros, incluso más allá del corto plazo. En presencia de dicha memoria el horizonte de inversión elegido puede resultar en diferentes...

Abstract Whilst emphasis has been given to short-term dependence of financial returns, long-term dependence remains overlooked. Despite financial literature provides evidence of long-term´s memory existence, serial-independence assumption prevails. This document´s long-term dependence...

Financial basics and intuition stresses the importance of investment horizon for risk management and asset allocation. However, the beta parameter of the Capital Asset Pricing Model (CAPM) is invariant to the holding period. Such contradiction is due to the assumption of long-term independence...

Scale-free (inhomogeneous) connective structures with modular (highly clustered) hierarchies are ubiquitous in real–world networks. Evidence from the main Colombian payment and settlement systems verifies that local financial networks have self-organized into a modular scale-free architecture...

We study the effect of relationship lending on small firms´ failure probability using a uniquely rich data set comprised of information on individual loans of a large number of small firms in Colombia. We control for firm-specific variables and find that small firms involved in long-term...

An interacting network coupling financial institutions’ multiplex (i.e. multi-layer) and financial market infrastructures’ single-layer networks gives an accurate picture of a financial system’s true connective architecture. We examine and compare the main properties of Colombian multiplex...

This study provides new evidence on the relationship between abnormal loan growth and banks´ risk taking behavior, using data from a rich panel of Colombian financial institutions. We show that abnormal credit growth during a prolonged period of time leads to an increase in banks´ riskiness,...

En este documento se realiza una exploración inicial sobre los determinantes del número de relaciones bancarias del sector corporativo privado de Colombia. Siguiendo otros estudios similares que se han realizado para distintos países, se utilizan modelos de datos de cuenta y se estima un...
