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...

Our aim is to examine whether sectorial production shocks have predominated in Mexico’s long annual real output, and whether shocks from different sectors are correlated. We study the long-run movement and comovements of 6 production sectors, using long, low frequency data for the Mexican...

The literature on spurious regressions has 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 for the dependent and explanatory variables. This paper...

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...
