This study investigates the underlying drivers of revenge buying behavior in the luxury sector during the COVID-19 pandemic. While prior research has largely treated revenge consumption as a form of compensatory behavior, the specific psychological motivations driving this phenomenon remain contested. Drawing on a cross-national dataset from 30 economically affluent countries, this study distinguishes two primary antecedents-perceived health threats and physical autonomy restrictions-and examines their respective effects on luxury consumption.
