The functioning of large-value payment systems (LVPSs) can be affected when some of its participants voluntarily decide to delay their payments until they can totally fund them with the payments received from other participants. This behaviour, known as the free-rider problem, can cause an under...

En este documento presentamos una radiografía sobre el uso del efectivo y de las tarjetas débito y crédito en Colombia, haciendo énfasis en la evolución histórica de su utilización. También se discuten algunos factores que explican el alto uso del efectivo que persiste en el país. Adicionalmente...

Even though international authorities encourage open and wide access to large value payment systems, the optimal level of access, or tiering, is still an open question.

We examine how liquidity is exchanged in different types of Colombian money market networks (i.e. secured, unsecured, and central bank’s repo networks). Our examination first measures and analyzes the centralization of money market networks. Afterwards, based on a simple network optimization...

Este trabajo estudia los efectos de la política monetaria de la Reserva Federal de Estados Unidos  durante la reciente crisis financiera (2008-2009) sobre los retornos accionarios de mercados emergentes. Mediante el análisis de un estudio de eventos se encuentra evidencia significativa de...

We implement a modified version of DebtRank, a measure of systemic impact inspired in feedback centrality, to recursively measure the contagion effects caused by the default of a selected financial institution. In our case contagion is a liquidity issue, measured as the decrease in financial...

A core goal of regulators and financial authorities is to understand how market prices convey information on the financial health of its participants. From this viewpoint we build an Early-Warning Indicators System (EWIS) that allows for identifying those financial institutions perceived as...

This paper presents a methodology to estimate the intraday liquidity that systemically important entities (SIE) need to fulfill all its obligations in a timely fashion, when a simulated failure-to-pay from its main liquidity supplier by discretionary concepts of payment occurs. Using the Bank of...

Large value payment flows can be disrupted by several types of failures such as operational incidents, problems experienced by the administrator of the payments settlement system, outages in the communications networks and the inability of a participant to submit payments due to insufficient...

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 and...

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.

Recientemente, las alteraciones de las condiciones climáticas, cada vez con mayor frecuencia e intensidad, vienen afectando la producción de alimentos en Colombia y en el resto del mundo, provocando por consiguiente una creciente volatilidad de los precios de los alimentos, la cual se suma al...

In the present paper we remark that the absence of an intrinsic or fundamental value represents a problem for the stability of the bitcoin’s price as an asset. In addition, we consider some financial stability concerns that derive from the hypothesis that the bitcoin will survive as an asset...

Evidence suggests that the Colombian interbank funds market is an inhomogeneous and hierarchical network in which a few financial institutions fulfill the role of “super-spreaders” of central bank liquidity among market participants. Results concur with evidence from other interbank markets and...

La investigación tiene como objetivo revisar de manera general la situación de la educación superior en Colombia y evaluar los niveles de eficiencia de los diferentes programas e instituciones del país. Para el análisis de eficiencia se utilizan técnicas de frontera estocástica y los resultados...

Despite various payment innovations, today, cash is still heavily used to pay for low-value purchases. This paper develops a simulation model to test whether standard implications of the theory on cash management and payment choices can explain the use of payment instruments by transaction size.

Under the view that the market is a weighted and directed network (Barabási, 2003), this document is a first attempt to model the Colombian money market within a spatial econometrics framework. By estimating two standard spatial econometric models, we study the cost of collateralized borrowing (...

This document presents an enhanced and condensed version of preceding proposals for identifying systemically important financial institutions in Colombia. Three systemic importance metrics are implemented: (i) money market net exposures network hub centrality; (ii) large-value payment system...
