Free-riding is a serious challenge in group projects. While there are various methods to reduce free-riding, marketing educators still face a difficult task when selecting an appropriate method for their course. In this study, we propose a students' preferences-based approach that supports marketing educators with the selection of methods to detect and handle free-riding. To measure these preferences, students completed an online survey based on a choice task about two methods to detect free-riding and a ranking task about four methods to handle free-riding (n = 254). Their answers were analyzed using chi-squared tests, Borda scores, and rank-ordered logit models. The results show that: (1) neither Dutch nor international students have a clear preference for one of the two detection methods (the reporting system vs. the process evaluation system); (2) grade discussion (a possible reduction of the free-rider's grade based on a conversation with the course coordinator about each student's contribution) is the most preferred method to handle free-riding; and (3) international students have a stronger preference for stricter handling methods. Marketing educators can apply the proposed approach, or use our specific findings, for designing methods to reduce free-riding in their courses.
