This study examines the time series properties of inflation in order to emphasize the nature of the shocks to the process. In particular, we offer evidence that US inflation may be characterized by low frequency permanent shocks, as opposed to the high frequency permanent shocks that is commonly...

An extension of the Holly and Gardiol (2000) and Baltagi et al. (2009) papers to the two way context, with heteroskedastic and spatially correlated disturbances is considered. One then derives a joint LM test for homoskedasticity and no spatial correlation. In addition, two conditional LM tests...

We re-examine the causality between the twin deficits by testing for Granger non-causality between BD and CAD based on extended causality tests initially developed by Toda and Yamamoto (1995). Using international data from a sample of twenty developed and developing countries, we find evidence...

This paper uses both linear and nonlinear causality tests to reexamine the causal relationship between the returns on large and small firms. Consistent with previous results, we find that large firms linearly lead small firms. We also find a significant linear causality in the direction from...
