Do people tip strategically, to improve future service? Theory and evidence

Abstract

. A central question about tipping is whether people tip strategically, to improve future service, or only because tipping is a social norm. I present a theoretical model that incorporates psychological utility associated with tipping (because it is a social norm) and allows tipping to be motivated also by future service considerations. The model predicts that if future service is a reason for tipping, the sensitivity of tips to service quality should be higher for repeating customers than for non‐repeating ones. Surveys of 597 restaurant customers are analysed and suggest that future service is not a reason for tipping. Une question centrale à propos des pourboires est la suivante: est‐ce que les gens donnent des pourboires stratégiquement pour améliorer la qualité du service ou est‐ce que le pourboire est simplement une norme sociale. L'auteur présente un modèle théorique qui incorpore à la fois l'utilité psychologique associée au pourboire (parce que c'est une norme sociale) et prend en compte que le pourboire peut être motivé aussi par des l'intention d'améliorer la qualité future du service. Le modèle prédit que si la qualité future du service est la raison pour donner des pourboires, la sensibilité des pourboires à la qualité du service devrait être plus grande pour les clients réguliers que pour les clients occasionnels. Des enquêtes auprès de 597 clients de restaurants suggèrent que la qualité future du service n'est pas la raison pour laquelle on donne des pourboires.
