Abstract

The appropriateness of physical distances as a proxy for interpersonal networks is examined using data on peer evaluation scores collected from undergraduate student presentations in econometrics courses during the spring 2010 and spring 2011 semesters at Franklin & Marshall College. Employing the Tobit regression technique and decomposing the resulting coefficient estimates into marginal effects, we find that greater physical distance is negatively related to peer evaluation scores in the sense that greater distance lowers scores and reduces the likelihood that the evaluating student will assign the maximum possible score. Similarly, evaluating students assign higher scores to those student presenters they consider friends.
