“…There are many studies which build theoretical models to understand the effects of a VAT on informality (Araujo & Rodrigues, 2016; Boadway & Sato, 2009; de Paula & Scheinkman, 2010; Emran & Stiglitz, 2005; Joshi, Prichard, & Heady, 2014; Kanbur & Keen, 2014; Keen & Mintz, 2004; Keen, 2008; Piggott & Whalley, 2001; Tumen, 2017).
