The Campbell and Vuolteenaho (Am Econ Rev 94(5):1249–1275, 2004) two–beta model decomposes the systematic risk in the sensitivity of cash flow and discount rate change. We employed this model, which we call the Two Beta Decomposition Model (TBDM) and found that this model is useful to compute the cost of capital for unlisted companies (UCs) via a p...
Article
The Disposition Effect (DE) describes the disposition of selling winners too early and of keeping losers for too long. Conventionally the DE is measure using trades and the average purchase price. Being more rigorous with its measure, we found that US institutional and mutual fund present some evidence of DE when we used trades as the unit of measu...

Purpose We test the informational efficiency of Venezuelan USD sovereign bond yields when the black market exchange-rate premium (BMERP) changes. Design We use a non-parametric, asymmetric, Granger causality test to test our hypothesis. Findings We find that the bond market with less than or equal to 5 years of maturity seems to be efficient when...

We test whether the differences in the national exam that measures student performance (Saber Pro) between public and private institutions is statistically significant by employing a propensity matching score approach bas...
Article
Purpose The purpose of this paper is to perform an event study using high frequency data on peso-denominated Colombian government bonds to measure the effects of news during the global financial crisis (GFC). Design/methodology/approach Using standard event study methodology, the authors want to see if a surprise (originating from macroeconomic ne...

This article investigates the informational efficiency of the Colombian stock market with regard to the information contained in the exchange rates as well as the yield to maturity. Since the underlying data is non-normal with time-varying volatility we make use of tests that are based on bootstrap simulations with leverage adjustments in order to...
Article
Full-text available
The purpose of this paper is to study if there is a Granger causality relationship between the price of oil and the prices of the stocks that compose the Integrated Latin American Market (MILA) index. Our analysis found that from the perspective of the efficient market hypothesis, there is no empirical evidence that there is a Granger causality rel...
Article
Finance literature suggests the use of the Accounting Beta (BACC) as a proxy for the Capital Asset Pricing Model (CAPM) market beta to estimate the cost of equity capital when the stock price is not available. Previous researchers have aimed to achieve this objective by determining the correlation between accounting variables and the market beta. H...

Full-text available
We analyse the effect of the Global Financial Crisis (GFC) on portfolios of USD denominated sovereign bonds. We use propensity matching estimators in order to measure the average difference in the volatility of sovereign spreads between the non-crisis and crisis period. We use a parsimonious factor model of local and global variables to create a se...
Article
The present paper calculates systematic risk within the context of the Capital Asset Pricing Model in order to investigate the significance of financial leverage. It develops a multinomial model with two theoretically predicted targets in the unleveraged/leveraged process, namely the proxy levered beta and an error term. This model allows us to add...

EVA® (Economic Value Added) is a commonly used financial indicator that measures the real profitability of a firm for a specific period of time. The main concept behind EVA® is that the real profitability of the firm is a function of its cost of capital, net operational profits after taxes (NOPAT) and the invested capital in the firm (IC). Is withi...

To that end, the proposed methodology is used to valuate this type of instrument in the company Transportadora de Gas del Interior Internacional Ltda. (TGI). In the...

Article
Many financial consultants, authors and teachers include changes in liquid assets (potential dividends) in the cash flows. This practice is against basic financial theory. We present economic, theoretical and empirical arguments to support the position to use only paid dividends in the cash flows. Hence when valuing cash flows we should consider pa...

The purpose of this paper is to clarify some of the difficulties that a practitioner may find in implementing the binomial model for valuing a corporate bond with multiple embedded options in emerging markets. Especially, when faced with the dilemma of determining which should be the proxy variables for the risk-free rate, sovereign risk and countr...

Muchos consultores, autores y profesores de Finanzas incluyen los cambios en los activos liquidos (dividendos “potenciales”) en los flujos de caja. Esta practica es contraria a la teoria basica de las finanzas. Presentamos razones economicas, teoricas, y empiricas para apoyar la tesis. Por lo tanto, al valorar flujos de caja, debemos considerar sol...

Article
An extensive body of knowledge has been developed around the theoretical relationship between the assumption that support the theory of the cost of capital and those that support the Portfolio-Capital Asset Pricing Model. The main discussion concerning how these theories are related is focused in the use of beta as a measure of systematic risk for...

Real Option Analysis (ROA) has become a very interesting method to evaluate real investment projects as it supports decision-making on project selection and timing. Black and Scholes' method was initially applied to financial options, but it has turned out an interesting method to evaluate real investment projects and it is a good tool for investor...

The purpose of this paper is to address how well the technique holds in an illiquid stock environment, such as the one in the Colombian stock market. Our objective is to measure the efficiency of Valueat-Risk in terms of the coefficient of variatio...

The Weighted Internal Rate of Return (WIRRo) is used to eliminate inconsistencies of traditional Internal Rate of Return (IRR) assumptions and instead to explicitly include Net Present Value NPV assumptions. The WIRR has been developed by authors who have analyzed the model. However, when implementing each author’s proposals, procedures and solutio...
