Extant research on academic cheating primarily focuses on the impact of honor codes on academic cheating. However, the influence of ethics institutionalization is curiously missing in past research. The authors developed and validated a structural equations model in the R programming language to examine the impact of formal (explicit) and informal (implicit) ways of institutionalizing ethics on reducing students' academic cheating. They found a significant mediating effect of implicit ethics institutionalization on the relationship between explicit ethics institutionalization and academic cheating among business students. Therefore, academic administrators are encouraged to place significant emphasis on implicit forms of ethics institutionalization to curb academic cheating among students.
