“…Lastly, I also examine regime‐switches, that is, two regimes with switching at the unconditional mean and standard deviation levels, for the respective net pairwise return spillover indices: gathered from Diebold and Yilmaz's (2012) spillovers framework (Hamilton, 1989; Schaller & Norden, 1997; Singh, 2020; Singh, 2021): where PS t is the net pairwise return spillover series at time t , and a 0 , a 1 , σ 0 and σ 1 are the mean and standard deviation levels across the respective regimes. The model follows a first‐order Markov chain, wherein the probability of a given state depends on the state last period ( S t ).…”
