RT Journal Article SR Electronic T1 Detecting and Preventing Cheating in Exams JF Journal of Human Resources FD University of Wisconsin Press SP 210 OP 241 DO 10.3368/jhr.0620-10947R1 VO 59 IS 1 A1 Cagala, Tobias A1 Glogowsky, Ulrich A1 Rincke, Johannes YR 2024 UL http://jhr.uwpress.org/content/59/1/210.abstract AB This work examines how to detect, document, and prevent plagiarism in exams. First, to identify and quantify plagiarism, we propose methods that compare similarities in multiple-choice answers between seat neighbors and nonneighbors. Second, we document cheating in undergraduate exams. Under baseline monitoring, at least 7.7 percent of the row-wise neighbor pairs plagiarized. Pairs composed of academically weaker students cheated more. Third, using a field experiment, we demonstrate that close monitoring eliminated cheating. By contrast, signing an honesty declaration doubled cheating relative to the control group. Complementary experiments suggest that the declaration backfired because it weakened the social norm of academic integrity.
