Group Rate Levels in Workmen's Compensation Insurance [Discussion]

Mr. McConnell's study of group rate levels has provided us with the important fact, not definitely realized before, that rate levels will vary by industry group, even though a single rate level is used for the entire state. The use of a single rate level will produce larger increases in rate level for some groups than will the use of group rate levels, whereas other groups, which would obtain large increases in rate level through the group rate level system, will receive smaller increases when the single rate level is used. He concludes that it would not be justifiable to depart from group indications merely because a larger increase could be obtained by keying to a single rate level.
