“…They showed that the performance of early warning systems can be enhanced using a country-specific approach, while Drehmann and Juselius (2014) employed the receiver operating characteristic (ROC) curve in developing early warning indicators of banking crises for 26 countries. Besides, Voon et al (2016) and Puah et al (2016) utilised the application of warning mechanism for the property cycle in Malaysia while Wong et al (2016) and Soh et al (2019) developed a system to deal with economic crises and tourism cycle, respectively. Additionally, Megersa and Cassimon (2015), Nguyen and Duy (2017), and Puah et al 2017developed an early warning system for Ethiopia, Vietnam, and Thailand, respectively, based on the signals approach.…”
