To comprehensively grasp, predict, and address the complexity of white collar crime, robust measurement tools are imperative. The burgeoning interdisciplinary interest in this domain has spurred the development of diverse assessment tools aimed at capturing offending behavior and its proxies. In the present paper, we provide an overview of the strengths and weaknesses of several commonly employed measures, including official statistics, victimization surveys, self‐report surveys, and (quasi)experimental measures. Drawing insights from this review, we then introduce a novel behavioral measure: the donation method. Although the task was originally designed to examine behaviors of interest to behavioral economists, we carefully outline strategies to refine and implement the donation method to assess white collar crime, addressing challenges such as task suitability and controlling for respondent behavior. Additionally, we provide a sample task to illustrate how such a tool could be used within this field. We conclude by underlining the appeal of adopting innovative measurement tools like the donation method to advance our collective understanding of white collar crime. By advocating for its widespread adoption and providing guidance for its use, we endeavor to catalyze progress in the field, facilitating unique insights and, potentially, more efficacious strategies for confronting and surmounting the methodological obstacles inherent in studying this elusive form of criminal activity.
