This paper analyzes the determinants of interest margins in the Colombian Financial System. Based on the model by Ho and Saun- ders (1981), interest margins are modelled as a function of the pure spread and bank-speci¯c institutional imperfections using quarterly data for the period...

The financial crisis of the late 2000's highlighted the importance of strengthening risk management systems in financial markets. Consequently, an increasing interest in strategies to quantify risk under extreme scenarios has spawned. One of such techniques is CrashMetrics, a methodology for...

Informational constraints may turn the Merton Model for corporate credit risk impractical. Applying this framework to the Colombian financial sector is limited to four stock-market-listed firms; more than a hundred banking and non-banking firms are not listed. Within the same framework, firms’...

The most widely-used measure of an asset's risk, beta, stems from an equilibrium in which investors display mean-variance behavior. This behavioral criterion assumes that portfolio risk is measured by the variance (or standard deviation) of returns, which is a questionable measure of risk. The...

Beta as a measure of risk has been under fire for many years. Although practitioners still widely use the CAPM to estimate the cost of equity of companies, they are aware of its problems and are looking for alternatives. One possible alternative is to estimate the cost of equity based on the...

In Colombia, the exposition to market risk has increased significantly since 2009. Nonetheless, the risk codependence among agents has not been analyzed yet from the perspective of this risk. Therefore, this paper presents an approach to estimate such relevance based on CoVaR and quantile...
