We investigate volatility contagion across G7 stock markets and the market for crude oil for the period between 2007 and 2021. Following the work of Balcilar et al. (2021), we utilise the TVP-VAR extended joint connectedness method and compare results to the standard TVP-VAR method that...

In this paper we test for the presence of fractional integration, or long memory, in the daily returns of exchange rates using ARFIMA(p,d,q) models. We consider 34 exchange rates against the US dollar (USD) covering the period April 1991 to April 2006. The results suggest that 17 exchange rates...
