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...

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...

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...

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 set a dynamic stochastic model for the interbank daily market forfunds in Colombia. The framework features exogenous reserve requirements and requirement period, competitive trading among heterogeneouscommercial banks, daily open market operations held by the Central Bank(auctions and window...

Poco se sabe en Colombia acerca de las competencias académicas de los maestros. Este documento investiga sobre el estándar académico de las personas que cursan y se gradúan de programas superiores en educación. Los resultados indican que existe una relación inversa entre el desempeño en la...

The most recent financial crisis unveiled that liquidity risk is far more important and intricate than regulation have conceived. The shift from bank-based to market-based financial systems and from Deferred Net Systems to liquidity-demanding Real-Time Gross Settlement of payments explains some...
