“…The first of these takes the form of endeavors to quantify the magnitude or impacts of the aggregate degree of federal income tax evasion in the macro-economy (Frey, Weck, and Pommerehne, 1982;Isachsen and Strom, 1985;Bajada, 1999;Giles, 1999;Fisman and Wei, 2004;Ledbetter, 2004Ledbetter, , 2007Cebula, 2018Cebula, , 2019Gale and Krupkin, 2019). The second component attempts to identify factors that influence the degree/extent of aggregate federal personal income tax evasion or compliance (Kirchgaessner, 1983;Hill and Kabir, 1996;Cebula, 1997Cebula, , 2004Friedman, Johnson, Kaufmann, and Zoido-Labton, 2000;Ali, Cecil, and Knoblett, 2001;Fisman and Wei, 2004;Martinez-Vazquez and Rider (2005); Richardson, 2006;Dell'Anno, 2007;Engstrom and Holmlund, 2009;Cebula and Feige, 2012;Ariyo and Belcoe, 2012;Phillips, 2014;Ameyaw and Dzaka, 2016;Chatzimichael, Kalaitzidakis, and Tzouvelekas, 2019).
