      abstract = {Measuring the effect of peers on individuals' outcomes is  a challenging problem, in part because individuals often  select peers who are similar in both observable and  unobservable ways. Group formation experiments avoid this  problem by randomly assigning individuals to groups and  observing their responses; for example, do first-year  students have better grades when they are randomly assigned  roommates who have stronger academic backgrounds? In this  paper, we propose randomization-based permutation tests for  group formation experiments, extending classical Fisher  Randomization Tests to this setting. The proposed tests are  justified by the randomization itself, require relatively  few assumptions, and are exact in finite samples. This  approach can also complement existing strategies, such as  linear-in-means models, by using a regression coefficient  as the test statistic. We apply the proposed tests to two  recent group formation experiments.},
