Interaction terms play an important role in empirical economic research. At the same time, standardization is often applied to make results comparable. Using both raises the question of the correct order, namely should one interact the standardized variables or standardize the interacted variables? Replicating prominent and highly cited papers, we show that both approaches potentially lead to substantially diferent results and explore the reasons for that. Accordingly, the aim of this paper is to strengthen the awareness of empirical esearchers for this issue in order to avoid unsuitable interpretations of standardized coefcients when using interaction terms.
