From bribes to bequests and gifts to gratuities: The black, white, and shades of gray of how and why consumers pay what they want.

This conceptual paper presents a framework that integrates 11 forms of voluntary payments as seemingly disparate as bribes and bequests, and gifts and gratuities to show that "voluntary" payments vary in the shades of gray not only in terms of how much like bribes they are but also in terms of how voluntary they actually are. We provocatively suggest that these payment types might be susceptible to becoming entrenched through self‐reinforcing norms because the voluntary payments are not necessarily voluntary and to an extent akin to bribes. Specifically, it provides an overarching framework to showcase the similarities and differences between bribes, lobbying efforts, suggested fees, pay what you want, tips, bequests, legacies, charity, crowdsourcing, dowry, and gifts, identifying gaps in domains that are under‐researched. Starting with the question as to whether a service has been, is being, or will be performed for the voluntary payment, and whether payments are made to an individual or a cause, the framework highlights the following: (1) the differences in the purpose underlying these payments, (2) the different modes of payment used; (3) the economic and social norms governing the payments; and (4) external and internal emotions associated with these payment types. The integrative framework allows for an amalgam of disparate literatures ranging from morality and behavioral pricing to charity and gift giving. The process model suggests a multitude of areas for future research in the domain of consumers' voluntary payment decisions. [ABSTRACT FROM AUTHOR]
