A study of cost curves in postsecondary education, using data from the top 66 research universities in the United States, estimated that the average cost per student falls with the number of students until enrollment reaches approximately 30,000 full-time undergraduate students. Consider the typical research university with an enrollment of 23,500 full-time undergraduate students (that was the average undergraduate enrollment at the top 63 public research universities in 2018/19, according to the National Science Foundation). (Ctrl) - Do these findings imply that the typical research university should grow in size (i.e., enroll more students)? Why or why not? Explain.
