Valuación de opciones de tipo de cambio asumiendo distribuciones α-estables

This paper aims to present the valuation of options using the Black-Scholes method assuming α-stable distributions as an alternative option valuation in the Mexican market. The use of α-stable distributions for modelling financial series allows to overcome the classical valuation main weakness which assumes normality, by capturing the presence of heavy tails and asymmetry in financial time series. One of the main results is the price differential between the two models and the effect of alpha and beta parameters on prices; to show the difference valuation is made of a call option and a put option for the peso-dollar exchange rate. Likewise, basic sensitivity measurements of options (delta, gamma, and rho) were made and the effect of the stability parameter (α) was made on the implied volatility of options assuming the α-stable price as the market price.     

Las incapacidades de aprendizaje organizacional y su relación con los estilos de aprendizaje organizacional en la Mipyme

In this study, we examined 200 micro, small and medium enterprises from Durango City, Mexico, in order to find the possible relationship between learning disabilities and organizational learning styles, and its impact on organizational learning. To achieve this we applied a measuring instrument to the aforementioned companies, it was duly adapted to the context, tested and validated, and the responses were analyzed using a linear regression model, which used the seven learning disabilities as predictors of the four learning styles. We found statistically significant evidence that there is a relationship between learning disabilities and learning styles in the studied enterprises.     

Estudio de la relación entre satisfacción laboral y el desempeño de los trabajadores de las ferias libres

This study analyzes and discloses the relationship between Job Satisfaction and Performance variables of a total population of 264 workers in Chilean Free Fairs. Out of the total population to which this research applies (264 individuals), the sample taken corresponds to 60% of each Fair, which is equivalent to 158 individuals. In order to obtain the objectives we applied a 54-item instrument. The first part collects general information about respondent; the second part collects average information of sales and salary to measure the workers’ productivity and the third part studies job satisfaction. Once performed the analysis of data collected, the results show that the dimensions of job satisfaction, boss relationship satisfaction and recognition satisfaction have a statistically significant relationship with productivity: daily sales/daily working hours. Good management of these can positively contribute to an increased competitiveness of Free Fairs. Another outstanding aspect included in this study is satisfaction with the physical environment, which has a statistically significant relationship between daily and monthly salary, which significantly contributes to the hours spent at work by individuals as well as the wage they perceive.     

Valuación de un producto estructurado de compra sobre el SX5E cuando la incertidumbre de los rendimientos está modelada con procesos log-estables

We report the participation level, we pricing a first generation's European call options on the Eurostoxx structured product, when returns’ uncertainty is modeled by log-stable processes, we present the basic statistics of the index's returns, we estimate the α-estable parameters, and we compare the structured products pricing by the both log-stable and log-Gaussian models using inputs of the debt markets. We conclude that investors get higher returns than debt markets using both models and returns’ differences depend of the participation level and the maturity.     

Evaluación del comportamiento de los indicadores de productividad y rentabilidad financiera del sector petróleo y gas en Colombia mediante el análisis discriminante

This research paper presents the results of the behavior of productivity and profitability indicators in the oil and gas sector in Colombia in the years 2008 and 2010 by means of discriminant analysis. Initially there is an analysis of the sector and a theoretical review of the financial management assessment, strategic leverage, stakeholders, agency theory, productivity and profitability indicators and basic concepts of discriminant analysis. In the methodology used, productivity and profitability indicators were calculated for 116 companies in the oil and gas sector from the financial statements in the periods of study. Then, the discriminant analysis technique was used to explain the belonging and discrimination of the indicators studied. From the discriminant function and the means obtained it can be concluded that the analyzed indicators do not present significant differences, which shows a period of stagnation in the periods studied. With the research work it was concluded, by discriminant analysis, that there is a significant difference just for the indicator gross margin. The discriminant function model allows an effective classification of 57.3%.     

Aprendizaje,innovación y gestión tecnológica en la pequeña empresa: Un estudio de las industrias metalmecánica y de tecnologías de información en Sonora

In the industrial development in Northwestern Mexico stands out the limited capacity of local firms to integrate into the global value chains and there is an emergent participation of the metalworking sector and information technology as suppliers of goods and services for large exporters. Recent local researches analyze the accumulation of technological capabilities, but they have not researched the relationship with technology management strategies. This paper presents the results of an empirical study of micro, small and medium enterprises in such areas, which allows the guessing of a direct correlation between the level of accumulated skills and the level of technology management.     

La oralidad y la escritura en el proceso de aprendizaje Aplicación del método aprende a escuchar,pensar y escribir

Research design is quasi-experimental, field, with four longitudinal assessments for two groups (one experimental and one control) of students with irregularity student. Intervention, learns listen-think-write (lltw) method. population, 488 students. With a sample conditioned (students with irregular registration) of 170 students from two university careers of accounting and administration, both manner, 24.3 years old. Material, Raven’s Progressive Matrices test and Learning strategies ACRA test. The impact obtained by the intervention (LLTW) was 23%, significant difference between follow-up evaluation 6 and 12 months. Regarding the improvement of learning skills in post-test measurement showed a general increase in average by 28%. Also it is necessary to say, the decline was failed subjects in the two groups evolving 12 months in control group was 3 to 4 and the experimental group was 1 to 2.     

Los efectos de largo plazo de la asimetría y persistencia en la predicción de la volatilidad: evidencia para mercados accionarios de América Latina

This article proposes an extension to the CGARCH model in order to capture the characteristics of short-run and long-run asymmetry and persistence, and examine their effects in modeling and forecasting the conditional volatility of the stock markets from the region of Latin America during the period from 2 January 1992 to 31 December 2014. In the sample analysis, the estimation results of the CGARCH-class model family reveal the presence of short-run and long-run significant asymmetric effects and long-run persistency in the structure of stock price return volatility. The empirical results also show that the use of symmetric and asymmetric loss functions and the statistical test of Hansen (2005) are sound alternatives for evaluating the predictive ability of the asymmetric CGARCH models. In addition, the inclusion of long-run asymmetry and long-run persistency in the variance equation improves significantly the out of sample volatility forecasts for emerging stock markets of Argentina and Mexico.
