We test the traditional Ohlson model and an international version of it. The international model includes the Dow Jones index as an additional explanatory variable. We use time-series and panel-data cointegration methodologies to assess the long-run relationships among the variables postulated by both models. We use quarterly data for the period 2000:01-2010:03. The results suggest that panel-data techniques may be better than time-series ones for the assessments. They support the use of the Ohlson models and, specially, the international one. The variables are significant and have the postulated signs. These results hold when the firms are considered as a whole and for the commercial and construction firms. Furthermore, the results also suggest that the Latin American asset prices are complementary to the US ones in...

This model aims to assess the impact of Discretionary Accrual Information (DAI) on financial reporting statements, in order to identify the value relevance of "earnings quality". We applied methodological criteria of Chung et al (2005) and Mukit & Iskandar (2009). We analyzed financial information of the 35 stock included in the Index of Prices and Quotations (IPC) of the Mexican Stock Exchange (BMV) for the period 2000 to 2011. 19 companies met the specifications of the model, for 48 quarters of information. The analysis was done in three parts: first, an analysis of the modified Jonesmodel under panel data considerations by using fixed effects and adjustments of performing autocorrelation of order 1; second, a correlation analysis between the residuals of the modified Jones´ model and the return of stock price in 3 annual closings years of study: 2007, 2008 and 2009; and third, we incorpo...

The volatility of oil returns is described through a TGARCH process. Conditional probability jumps are incorporated through uniform, double exponential and normal jump intensity distributions. We found that the volatility of oil returns follows the stylized facts of leptokurtosis, leverage effect and volatility clustering. The abnormal information that causes the jumps, can cause another type of unexpected changes in the following period and the intensity of the jumps has a negative effect on the probability of jumps in the next period. The dynamic model proposed can be extended to other markets and to multivariate time series modeling considering the dependence among the markets’ returns. The main contribution of this work is the estimation of the conditional probability of jumps depending on the previous behavior leading to a better description of the stochastic dynamics of crude oil prices. This will be usefu...

Se construye un modelo con tecnicas de analisis de datos de panel, encontrando que las variables macroeconomicas son relevantes, no asi las contable-financieras. / In this study, we presented factorial model review by incorporating macroeconomic and accounting-financial variables, in order to identify the value relevance of them on the return of the Mexican Stock Market. We used a model under the panel data considerations and we found that only the macroeconomic variables were significant, but not the accounting-financial variables.

This is made for the Mexican stock market returns. The parameters of the NIG and t-Student distributions are estimated by maximum likelihood. The rejection of normality is contundent using the omnibus test. The results are very clear: the adjustment of the NIG distribution is better than the adjustment for the Normal distribution. At the same time we used de Kolmogorov-Smirnov test to compare t-Student and NIG distributions.

The data is used on a quarterly basis from January 2000 to December 2011. It also makes reference to the impact of having the distinction "Socially Responsible Company" (Corporate Social Responsibility), in the Mexican stock market price reaction. Our main interest is to be pioneers in the search for relationships between topics that are currently treated as "alien" (CSR and Innovation) in formal academic publications, but we intuitively know that they are related inside organizations.

El mismo se construye usando la metodología de Fernández y Steel (1998) y el modelo TGARCH tradicional desarrollado por Zakoian (1994). El modelo se usa para describir series de rendimientos bursátiles y para evaluar la validez de las hipótesis de racionalidad en Latinoamérica. Los resultados sugieren que: 1) Las series de rendimientos analizadas pueden describirse adecuadamente con el modelo propuesto;

It is added the beta coefficient to the traditional Ohlson model. The econometric analysis was done using time series and panel-data cointegration methodologies. It was found that the analysis under panel-data techniques is better for the Mexican data. The results show the correct signs in the variables (for both models) but the beta is only statistically significant in the stock prices of firms with short operating cycles.

Symmetric Joe-Clayton copula is used and conditional probabilities of increases (decreases) in Mexico stock index when there are increases (decreases) in the U.S. stock index are estimated. For the marginal distributions, AR-TGARCH and AR-EGARCH models with a standardized Student's t distribution for innovations are proposed. Empirical results suggest that there is a high degree of conditional dependence in the tails, presenting higher volatility on the upper (right) tail throughout the period.

We use the model for modelling series of stock-market returns and for investigating some risk-management criteria prevailing in the Latin-American stock markets. The main results support the usefulness of the model. Particularly, they suggest that hedging and diversification practices among the markets may be useful for risk-management purposes. Moreover, they suggest that the most risk-averse investors are in Argentina and the least risk-averse ones in Colombia. Furthermore, they imply that the behaviour of investors may be more complex than the one postulated by the mean-variance paradigm.

This means that, in addition to the conditional mean and variance, we assume that the skewness describes the behavior of the time-series. Analytically, we use the methodology proposed by Fernandez and Steel (1998) to define the behavior of the innovations of the model. We use the approach developed by Brooks, et. al., (2005), to build it. Moreover, we show its usefulness by modeling the daily returns of the Mexican Stock Market Index (IPC) during the period between January 3rd, 2008 and September 29th, 2009.

Implicit volatility is included in each regimen as an indicator of fear among informed investors. Conditional variance equation includes factors that represent investor’s overconfidence to determine if this emotional bias affects returns

Se parte la muestra en tres periodos: antes, durante y después de la crisis de 2008. El comportamiento de las distribuciones marginales se describe mediante modelos AR(1)-TGARCH que resultan modelos adecuados para describir el comportamiento de los rendimientos y su volatilidad. Encontramos que los mercados de valores latinoamericanos presentan una mayor probabilidad de pérdidas extremas que de ganancias extremas y que la estructura de dependencia entre ellos se fortalece más en los períodos de crisis.

EL PROPÓSITO DEL ESTUDIO ES PROBAR EL PODER EXPLICATIVO DE LAS VARIABLES CONTABLES EN EL PRECIO DE MERCADO DE LAS ACCIONES DE LAS EMPRESAS QUE COTIZAN EN LA BOLSA MEXICANA DE VALORES, DE 1991 A 2003. EL VALOR DE RELEVANCIA SE ANALIZA UTILIZANDO EL MODELO DE OHLSON (1995) DE LA LÍNEA DE INVESTIGACIÓN CONTABLE BASADA EN EL COMPORTAMIENTO DEL MERCADO.

Las pruebas de cointegración se realizaron de forma individual y a nivel de grupo total y por grupo de sectores. Las empresas estudiadas pertenecen a los sectores económicos de alimentos y bebidas, comercial y construcción, que cotizan en el Mercado Accionario Mexicano. Los datos utilizados fueron trimestrales de 1997 a 2008. Los resultados empíricos, basados en la prueba de Johansen, muestran que existen relaciones individuales de cointegración. Los resultados de las pruebas de cointegración en panel indican que las variables del modelo de Ohlson no están cointegradas para el sector de construcción, pero sí lo están para los sectores comercial y de alimentos y bebidas.

Resumen En este estudio se analiza la relación entre el precio del petróleo (bajo la referencia del Precio Brent) y la rentabilidad de las empresas que cotizan en la Bolsa Mexicana de Valores. El periodo de análisis fue semanal de 2006 a 2010 (siendo 208 observaciones). Se encontró correlación positiva condicional utilizando un modelo de BEKK. Se presentan gráficas del comportamiento de cada empresa y el precio del petróleo.
