“…The follow-up studies use the psychological approach in analyzing tax compliance, such as tax morale (Jones, 1991; Andreoni et al , 1998; Dolores et al , 2010; Cyan et al , 2016), taxpayers’ trust (Hammar et al , 2009; Dijke and Verboon, 2010; Kostritsa and Sittler, 2017; Faizal et al , 2017), social norms (Damayanti, 2012; Bobek et al , 2013) and the feeling of caring and worrying (Bayissa and Van-Dijke, 2017). Several studies also combine the economic approach with the psychological approach in investigating the tax compliance phenomenon (Kirchler et al , 2008; Kastlunger et al , 2013; Kogler et al , 2013; Palil et al , 2017) or as commonly known as the slippery slope framework.…”
