The Influence of Risk-Taking on Bank Efficiency: Evidence from Colombia

We present a stochastic frontier model with random inefficiency parameters which is able to capture the influence of risk-taking on bank efficiency and that distingues those effects among banks with different characteristics. Cost and profit efficiency are found to be over- and underestimated...

The Factor-Portfolios Approach to Asset Management using Genetic Algorithms

We present an investment process that: (i) decomposes securities into risk factors; (ii) allows for the construction of portfolios of assets that would selectively expose the manager to desired risk factors; (iii) perform a risk allocation between these portfolios, allowing for tracking error...

The Cost of Collateralized Borrowing in the Colombian Money Market: Does Connectedness Matter?

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 (...

The case for active management from the perspective of Complexity Theory

This paper approaches active management of baskets of currencies from the perspective of Complexity theory, where the market is analysed as a Complex Adaptive system. A basket of currencies is constructed using objective probabilities (propensities) and an artificial intelligence optimization...

Scale-Free Tails in Colombian Financial Indexes: A Primer

A maximum likelihood method for estimating the power-law exponent verifies that the positive and negative tails of the Colombian stock market index (IGBC) and the Colombian peso exchange rate (TRM) approximate a scale-free distribution, whereas none of the heavy tails of a local sovereign...

Portfolio Optimization and Long-Term Dependence

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 assessment relies...

Operational Risk Management using a Fuzzy Logic Inference System

Operational Risk (OR) results from endogenous and exogenous risk factors, as diverse and complex to assess as human resources and technology, which may not be properly measured using traditional quantitative approaches.  Engineering has faced the same challenges when designing practical...

Monetary transmission under competing corporate finance regimes

The behavioral agent-based framework of De Grauwe and Gerba (2015) is extended to allow for a counterfactual exercise on the role of corporate finance arrangements for monetary transmission. Two alternative firm financial frictions are independently introduced: market-based and bank-based. We...

Leverage Pro-cyclicality and Bank Balance Sheet in Colombia

The recent financial crisis has renewed the interest of economists, both at the theoretical and empirical level, in developing a better understanding of credit and its mechanisms. A rapidly growing strand of the literature views banks as facing funding restrictions that...

Investment Horizon Dependent CAPM: Adjusting beta for long-term dependence

 

Financial Soundness Index for the Private Corporate Sector in Colombia

This paper has as main objective to build a composite metric of financial soundness for the private corporate sector in Colombia. Instead of relying on the individual and sometimes restrictive financial ratio analysis approach, the purpose of this document is to provide a single metric aimed at...

Efficient Portfolio Optimization in the Wealth Creation and Maximum Drawdown Space

First developed by Markowitz (1952), the mean-variance framework is the most widespread theoretical approximation to the portfolio problem. Nevertheless, successful application in the investment community has been limited. Assumptions such as normality of returns and a static correlation matrix...

Does the Use of Foreign Currency Derivatives Affect Colombian Firms’ Market Value?

Classic financial theory relies on the absolute perfection of capital markets, which results in one of the milestones of theoretical corporate finance: the firm’s value is invariant to the choice of capital structure. As an extension to the aforementioned proposition by Modigliani and Miller (...

Does ownership structure affect trade credit policy in small- and medium-sized firms? Evidence from China

This paper examines whether and how ownership structure affects the trade credit policies in small- and medium-sized firms (SMEs) using a sample obtained from a survey of Chinese enterprises. Specifically, we examine how ownership concentration affects SMEs’ use of trade credit through...

Credit Pro-cyclicality and Bank Balance Sheet in Colombia

The recent financial crisis has renewed the interest of economists, both at the theoretical and empirical level, in developing a better understanding of credit and its mechanisms. A rapidly growing strand of the literature views banks as facing funding restrictions that condition their borrowing...

CrashMetrics: An Application for Colombia

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...

Comparison of Methods for Estimating the Uncertainty of Value at Risk

Value at Risk (VaR) is a market risk measure widely used by risk managers and market regulatory authorities. There is a variety of methodologies proposed in the literature for the estimation of VaR. However, few of them get to say something about its distribution or its confidence intervals....
