“…Changes in oil prices, using level value or log-differences as proxy variables, have been applied in many empirical literature; but an attempt to break oil price fluctuations into four sources has only recently been documented in the literature (Baumeister and Hamilton, 2019), as a follow-up to the initial attempt to disaggregate oil shocks into their various components to determine their distinct impacts (Kilian, 2009;Kilian and Park, 2009). These oil shocks, which include economic activity, supply, aggregate demand, and precautionary demand shocks, are defined based on perceived causes of oil price fluctuations, and are now being increasingly used in the literature (see Adekoya and Oliyide, 2020;Salisu and Gupta, 2020;Adekoya, Ogunbowale, Akinseye and Oduyemi, 2021). Supply shock expectations of oil are majorly influenced by the availability of crude oil supply and the uncertainty regarding its continuous availability of its production.…”
