“…Several theoretical and empirical studies have shown inflation being influenced by both demand- and supply-side factors (Bandara, 1996; Colombage, 2005; Cooray, 2008; Deyshappriya, 2014; Jayawardena & Jayasinghe, 2016; Kulatunge, 2012; Nicholas, 1993; Ratnasiri, 2009; Rupananda, 1994; Weerasekara, 1992). Furthermore, the literature on inflation has discussed, inter alia , inflation persistence across exchange rate regimes (Harischandra, 2007), the magnitude of pass-through rates (Wimalasuriya, 2007), monetary policy impact on growth and inflation (Amarasekara, 2008), inflation–unemployment trade-off (Amarasekara & Bratsiotis, 2015), inflation–output trade-off (Kesavarajah & Middleditch, 2019) and the contribution of oil price (Perera, 2005) and other factors to the inflation in Sri Lanka (De Silva, 2017).…”
