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...

This paper extends recent research on the behaviour of the t-statistic in a long-horizon regression (LHR). We assume that the explanatory and dependent variables are generated according to the following models: a linear trend stationary process, a broken trend stationary process, a unit root...

Mexican economic historiography recognizes the key role that public investment played in the country's economic performance from the post-revolutionary period until the beginning of the economic liberalization that began in the mid-1980s. However, there is no concrete empirical evidence that...

The authors construct a historical database of public investment (both total and broken down into its main components) for the period 1925 to 1981 in order to measure its impact on economic activity. Given the possible presence of crowding-out effects between public investment and private...

Polynomial specifications are widely used, not only in applied economics, but also in epidemiology, physics, political analysis and psychology, just to mention a few examples. In many cases, the data employed to estimate such specifications are time series that may exhibit stochastic...

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...
