“…In order to address these issues, typologies have been often used to better distinguish corrupt behaviors not only on the basis of specific mechanisms, attributes, procedures and sectors, but also in relation to precise personal attitudes and motivations. The most common classifications of corruption are those distinguishing between grand and petty corruption (Rose-Ackerman, 1978), administrative and political corruption (Gould, 1991;Huberts, 1998;Navot, 2014, Holmes, 2015OECD, 2015;World Bank, 2003), illegal and legal corruption (Kaufmann & Vicente, 2011;Maciel & De Sousa, 2018); the type of gain (tangible or intangible) involved in the transaction (UNODC, 2006;OECD, 2007;OECD, 2008;Villeneuve et al, 2019) and the principal's or agent's motivation for participating in the transaction (collusive vs. extortionary corruption) (Bauhr & Grimes, 2017;Jancsics, 2019;Ryvkin et al, 2017).…”
