Testing for contagion from oil and developed markets to emerging markets : an empirical analysis using systemic risk parameter
This paper analyses the volatility transmission from changes in prices in oil and developed stock markets to emerging markets. We test for volatility contagion from these two factors while allowing for interaction between them in order to account for diversification effects using the M-GARCH framework in a traditional two-factor market model. We find evidence that for all the periods under observation the covariance between developed markets and oil prices is negative. This negative covariance leads to a diversification effect, which lowers the impact of developed market prices on the systemic risk of emerging markets and gives support for the decoupling hypothesis concerning emerging market volatility during the beginning of the global financial crisis (GFC).https://orcid.org/0000-0002-4113-5521https://orcid.org/0000-0001-5986-4813https://www.scopus.com/authid/detail.uri?authorId=56395390800https://www.scopus.com/authid/detail.uri?authorId=5719646546
A test of the efficient market hypothesis with regard to the exchange rates and the yield to maturity in Colombia
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 create reliable critical values. The results show that neither the exchange rates nor the yield to maturity is causing the stock price index. This is interpreted as empirical support for the efficient market hypothesis in that the Colombian stock market is with regard to these two main variables.https://orcid.org/0000-0001-5986-4813https://orcid.org/0000-0002-6212-1292https://orcid.org/0000-0002-4113-5521https://www.scopus.com/authid/detail.uri?authorId=57196465468https://www.scopus.com/authid/detail.uri?authorId=6603559832https://www.scopus.com/authid/detail.uri?authorId=5639539080
Does attending a public or private university make a difference for students in Colombia?
In this paper, we explore the difference in quality between public and private higher education institutions (HEIs) in Colombia. 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 based on common financial characteristics to avoid issues of selection bias. The results indicate that the difference in student performance between public and private institutions is positive and statistically significant. There is evidence that students in private HEIs perform better in most areas of the Saber Pro than their public counterparts. This performance difference can be attributed to the substantial differences in the patterns of teaching expenditures and income per student between public and private HEIs. The results are robust, since we controlled for statistical differences between private and public universities in terms of growth of revenue, number of undergraduates, number of full-time professors, and income per student by using propensity matching estimators for counterfactual samples.https://orcid.org/0000-0002-4113-5521https://orcid.org/0000-0003-3958-3701https://orcid.org/0000-0001-5986-4813https://www.scopus.com/authid/detail.uri?authorId=56395390800https://www.scopus.com/authid/detail.uri?authorId=56424018700https://www.scopus.com/authid/detail.uri?authorId=5719646546
POTENTIAL DIVIDENDS AND ACTUAL CASH FLOW. A REGIONAL LATIN AMERICAN ANALYSIS
We examine the value market assigns to components of the cash flow to equity including potential dividends. We study non financial publicly traded firms from five Latin American countries. The model includes four variables: market value of equity, dividends paid, change in equity investment and change in liquid assets (potential dividends) and are regressed with actual equity value as dependent variable. Tests applied give robust results. The main conclusions: Market assigns less than one dollar to a future dollar for any of the variables studied. Potential dividends destroy value. A dollar invested in liquid assets has a negative Net Present Value and it is not zero NPV investments. We confirm the agency costs of keeping undistributed cash flows.Cash flow to equity, potential dividends, equity value.
