DISCUSSION.

The article presents discussions by economists on some papers that are published in the May 1, 1970 issue of the journal "American Economic Review." The author states that his comments are directed mainly to the paper by economist R. Radner and L.S. Miller. The author is particularly interested in the data Radner and Miller have assembled on variations in faculty-student ratios among groups of institutions and over time. However, before commenting on that aspect of their paper, the author wants to know how student aid is treated in their analysis. The author cannot tell from the paper itself how this variable has been handled and yet it is clearly of great importance in many cases. To return to the faculty-student ratios, the intriguing question is, of course, related to observed patterns. The difficulty that Radner and Miller have had to-date in finding systematic relationships between faculty-student ratios and other variables, or even in presenting much in the way of conjectures, attests to the complexity of the problem. It also serves as a challenge to economists to come up with some ideas of their own. In this spirit, the author suggests that variations in faculty-student ratios can be understood only in the context of more complete behavioral models for various groups of institutions.
