This study uses individual-level data to examine whether the use of a crib sheet can boost the test performance of students in principles of economics. We find that crib sheets have the potential to significantly improve student performance, an outcome that is largely attributable to performance in principles of macroeconomics. Based on our findings, there is no clear indication that cooperative crib sheets, as implemented in this experiment, are more effective than individual crib sheets. In fact, we find that the collaborative process may hinder performance. We find that female students do worse on tests generally and that students with a higher academic classification and more academic talent tend to do better. However, we don’t find that crib sheets heterogeneously impact performance within these groups.

这项研究使用个人数据来检验使用婴儿床床单是否可以提高经济学原理的学生的考试成绩。我们发现婴儿床床单有可能显着提高学生的表现，这一结果很大程度上归因于宏观经济学原理的表现。根据我们的发现，没有明确的迹象表明，如本实验中所述，协作式婴儿床比单个婴儿床更有效。实际上，我们发现协作过程可能会影响性能。我们发现，女学生的考试成绩总体上较差，而具有较高学业成绩和更多学术才能的学生往往会做得更好。但是，我们没有发现婴儿床床单对这些组的性能有不同的影响。
