“…Taking an even broader view, occupational differences in tipping and their implications for tipping policies represent just one of many tipping related topics of relevance to economists. Also relevant to economists are the effects on tipping of variables such as consumer personality and/or motivation (Lynn, 2015b), new technologies and/or payment methods (Haggag and Paci, 2014), and national identity, culture and/or values (Lynn and Starbuck, 2015) as well as tipping's effects on consumers, employees, sales, and/or profits as a form of buyer monitoring (Jacob and Page, 1980), conspicuous consumption (Lynn, 1997), voluntary pricing (Natter and Kaufmann, 2015), price partitioning (Lynn and Wang, 2013), price discrimination (Schwartz, 1997), service-guarantee/risk-reducer (Holland, 2009), employee incentive/reward (Azar, 2004), and feedback about consumer satisfaction (Voss et.al., 2004) as well as its effects on economic-efficiency (Conlin et.al., 2002) and socialwelfare (Azar, 2005b). Some research investigating these aspects of tipping has been conducted (see cited papers above), but much more is needed.…”
