“…A substantial body of literature confirms the importance of psychological factors on the decision-outcome with respect to tax evasion, like framing effects (e.g., Chang, Nichols and Schultz, 1987;Kirchler and Maciejovsky, 2001;Robben, Webley Elffers and Hessing, 1990;Schepanski and Shearer, 1995), perceived justice and fairness (e.g., Dornstein, 1987;Kirchler, 1997;Spicer and Becker, 1980;Spicer and Lundstedt, 1976), the importance of attitudinal aspects (e.g., Kirchler, 1999;Lewis, 1979;Vogel, 1974), the role of opportunity (e.g., Clotfelter, 1983;Groenland and van Veldhoven, 1983;Porcano, 1988;Wärneryd and Walerud, 1982;Wallschutzky, 1984;Weigel, Hessing and Elffers, 1987), etc. There are also other studies focussing on legal tax avoidance, indicating that respondents believe that the "ordinary people" have to bear most of the tax burden (Kinsey, 1984) and that they wish to reduce tax-loopholes (Song and Yarbrough, 1978).…”
