It has been found that the t-statistic for testing the null of no relationship between two independent variables diverges asymptotically under a wide variety of nonstationary data generating processes. This paper introduces a simple method which guarantees convergence of this t-statistic to a...

En este estudio se analiza la hipótesis de convergencia entre regiones de la República Mexicana desde 1940, con particular interés en el periodo posterior a la liberación económica. Un análisis de series de tiempo muestra que la diferencia en ingreso per capita entre la región Capital y...

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...

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,...
