John Merrifield (in this issue) raises three important observations regarding this review of the literature on the competition effects of school vouchers. The first is an acknowledgment of the limited nature of current school choice markets in the United States. Merrifield's second observation is that the potential responses to competition that Egalite hypothesizes may be occurring are not actions that are typically undertaken at the school level, even though the enrollment loss threats are occurring at the school level. Merrifield's third is that rivalry behavior between schools for student enrollment may not fully explain the responses observed. Egalite responds to Merrifield's comments in this article.
