“…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). Samaratunga and Perera (2015) looked at the demand and adequacy of international reserves in Sri Lanka.…”
