En este documento se estudian los determinantes de la heterogeneidad observada en la flexibilidad de precios, empleando los resultados encontrados en una encuesta directa por Misas et al. (2009). Para esto se utilizan los modelos de conteo y se diseñan e implementan un conjunto de pruebas de...

The spurious regression phenomenon, identified by Granger and Newbold (1974) is well known in econometrics. In fact, spurious regression occurs under a wide variety of Data Generating Processes: driftless unit root, unit root with drift, trend stationarity, broken-trend stationarity,… However,...

We present a new heteroskedastic conditional variance model using NonLinear Moving Average as the basis for this specification [NLMACH(q)]. The typical problem of this class of models-i.e., noninvertibility—is solved by means of an intuitive parametric restriction; this allows us to use...

This paper shows that the evolution of the level of Mexico real and real per capita output between 1895 and 2008 can be adequately described through a trendstationary model, affected by 4 structural breaks, which occurred at dates that seem to coincide with domestic institutional arrangements,...

Spanish Abstract: Se presentan los resultados básicos de la teoría de control óptimo en contextos estocásticos y su aplicación en el planteamiento y resolución de problemas financieros. En particular se consideran los problemas de selección óptima de portafolios y la valoración de...

Migration movements in the south border of México with Guatemala, has motivated serious social, economic and politic un-stability in both countries. During the last decades of the XX-th century, the sites of the south zone have become in zones with high violence indexes, delinquency and...

It is known that, when in the linear regression model there is a high degree of multicollinearity, the results obtained by using the Ordinary Least Squares (OLS) method are unstable. As a solution to this situation, in this paper we present the raised method, the ridge method and the orthogonal...
