Management Science
Construct-based models (e.g., PLS path modeling and CBSEM) have become a mainstay of management research. However, these models are likely overfit to the data samples upon which they are estimated. We propose a composite overfit analysis (COA) framework that applies predictive tools to describe the sources and ramifications of overfit in terms of the focal concepts important to empirical researchers. The framework employs a novel deviance tree method to group deviant cases that have similar predictive deviance and for similar theoretical reasons.
Information & Management
Users of rival technology platforms, such as Android-versus-iOS, often harbor hostile opposition to each other. We conducted an empirical study of smartphone users, where we find that the threat to technology self-esteem arises from distinct antecedents and offers a singular explanation for opposition. Moreover, we show the unintended consequences of employing lock- in strategies and provide advice on why and how to mitigate them.
