This essay presents a general outlook and an analysis of the rationale behind the use of qualitative methods, including their being applied in research in Management. According to the views of methodological monism, the contribution of the conclusions which these methods yield, which are essentially subjective and not susceptible of being generalized, is considered too limited; while for advocates of constructivism and pluralism they are valuable in probing the depth of the phenomena of these disciplines. In fact, a lack of consensus prevails in these areas even in connection with what are qualitative methods and what are qualitative research techniques, associated to an indistinct use of these terms by some authors; which together with the number and diversity of qualitative methods makes it difficult to understand what actually is qualitative research.
Pronóstico de los índices accionarios DAX y S&P 500 con redes neuronales diferenciales Fecha de recepción: 11.12.2012 Fecha de aceptación: 12.04.2013
ResumenEn este trabajo se utiliza una red neuronal diferencial (RND) para describir las series de valores de cierre diarios de los índices accionarios DAX de Alemania y S&P 500 de Estados Unidos entre el periodo del 3 de julio de 2000 y el 13 de enero de 2012. Con la RND se lleva a cabo el pronóstico de los valores de cierre diarios de esos índices durante un periodo de cuatro semanas (del 16 de enero al 10 de febrero de 2012). Los resultados obtenidos confirman el hecho de que las redes neuronales diferenciales pueden constituirse en una de las herramientas más poderosas y precisas para poder pronosticar valores futuros de activos financieros.
<p>El objetivo del artículo es analizar si la relación entre la inflación y el crecimiento económico en México durante 1993-2018 fue lineal o no; a tal efecto, elaboramos un modelo dinámico de rezagos distribuidos no lineales. La hipótesis nula es que esa relación es lineal y la hipótesis alternativa acepta que no es lineal. Si la evidencia empírica documenta una relación lineal, la hipótesis nula implicaría que: 1) la inflación es un fenómeno puramente monetario <em>a la</em> Friedman (1968); 2) la estabilidad de precios alcanzada mediante la política monetaria del nuevo consenso macroeconómico es condición necesaria y suficiente para la aceleración del crecimiento y la superación del prolongado estancamiento de la economía mexicana, y 3) el dinero es neutral. Por el contrario, si los datos muestran una relación no lineal, se rechazarían la hipótesis nula y las implicaciones antes enunciadas.</p><p><strong> </strong></p><p align="center">ECONOMIC GROWTH AND INFLATION IN MEXICO, 1993-2018: A LINEAR OR NON-LINEAR RELATIONSHIP?</p><p align="center"> </p><p align="center"><strong>ABSTRACT</strong></p>The paper is aimed at assessing whether the relationship between Mexico’s economic growth and inflation has been linear or non-linear over the period 1993-2018. A non-linear dynamic autorregresive distributive lag model is elaborated to test both the null hypothesis of a linear relationship between the involved variables and the alternative hypothesis of a non-linear relationship. An empirical support for the the null hypothesis would imply that: 1) inflation is purely a monetary phenomenon (Friedman, 1968); 2) price stability, as achieved by means of the monetary policy framework of the new macroeconomic consensus, is both a necessary and sufficient condition for output growth acceleration and for overcoming the protracted stagnation of the Mexican economy, and 3) money is neutral. By contrast, if the empirical evidence confirms a non-linear relationship, both the null hypothesis and its ensuing implications would be rejected.
Applying a multifactor beta model, this papers examines the case of the NAFTA countries, Mexico, Canada and United States. Its objectives are, first, identifying the relationship between local macroeconomic factors and asset pricing at each market; and, second, examine the integration of each market to global market macroeconomic variables. Results show that local factors weight more than international factors at each market, revealing mild segmentation among these markets. The level of integration of local markets with global variables is greater for United States, while for Mexico is the lowest.
