Abstract

This paper incorporates applied econometrics, causal machine learning and theories of reference-dependent preferences to test whether consuming in a restaurant on special occasions, such as one's birthday, anniversary, graduation, etc., would raise one's expectations of the restaurant and would increase consumers' tendency to rate their consumption experiences lower. Furthermore, our study is closely linked to the emerging literature of attribution bias in economics and psychology and provides a scenario in which we can empirically test two leading theories of attribution bias. In our paper, we analyzed reviews from Yelp and combined the text analyses with regressions, matching techniques and causal machine learning. Through a series of models, we found evidence that consumers' ratings for restaurants are indeed lower when they go to restaurants on special occasions. This result can be explained by one theory of attribution bias according to which people have higher expectations about restaurants on special occasions and then misattribute their disappointment to the quality of the restaurants. From the connection between our empirical analysis and theories of attribution bias, this paper provides evidence of how attribution bias influences people's perceptions and behaviors.
