This paper investigates the relationships among real, monetary and financial variables in the Australian economy using seasonally unadjusted monthly data series spanning the period January 1978 to June 1994.

In this paper, linear and non-linear Granger causality tests are used to examine the dynamic relationship between daily Korean stock returns and trading volume. We find evidence of significant bidirectional linear and non-linear causality between these two series. ARCH-type models are used to...

This paper develops a time domaine score statistic for testing fractional integration at zero and seasonal frequencies in quarterly time series models.
