Information is crucial in economic decision making and has been extensively used for policy purposes (e.g. nudges). However, as shown by many previous studies, providing more information does not always lead to better outcomes. In a field experiment we test how different information structures influence students’ productivity. We implement several treatments (i.e. ranking information and/or publicity) randomly to determine how midterm grades are released to students. To our surprise, all treatments adversely affect the students’ performance in their final examinations. With further analysis, we find that the information treatments have slightly positive but insignificant effects on better ranked students but cause much larger and statistically significant negative effects on lower ranked students. Survey data are then used to examine behavioral and attitude changes. Results show that students mistakenly shirk from studying due to the extra information they receive.
