Custom Comparison Groups in the Integrated Postsecondary Education Data System

: This Economic Commentary studies the behavior of colleges when they are asked to list a set of comparison group colleges in annual data reporting for the US Department of Education but are given little direction on how to do so. I find that, relative to themselves, colleges tend to list for comparison colleges that are more selective, are larger, and have better resources. One possible interpretation of these findings is that colleges overestimate where they stand relative to others, although an alternative interpretation is that colleges have accurate views but list comparison institutions based on aspirations.
