This paper focuses on the factors that significantly influence an individual’s decision in establishing a price for a standardised product under so-called pay-what-you-want (PWYW) circumstances. Current research has identified seven influential constructs that are assumed to be the main drivers of consumer behaviour when making a pricing decision in a PWYW environment: fairness, altruism, loyalty, price consciousness, income, satisfaction and reference price. This paper extends the list of influential factors with an additional construct, situational factors and examines the constructs’ relative importance with regard to their influence on a PWYW decision. Moreover, the positive effect of personal interaction on a buyer’s willingness to pay during a payment situation in the PWYW context was confirmed.
