Some Observations on the Development of Manual Rates for Workmen'sCompensation Insurance [Discussion]

Mr. Perkins calls attention to the most difficult problem in workman's compensation rate-making. It is relatively easy to obtain a satisfactory degree of accuracy in the relativity of rates between classifications. This relativity does not, except in a few unusual industries, appear to change radically. It seems possible, therefore, to use rather a wide experience over an extended period of years to develop a schedule of relative rates and to use this scale of relativity for a period of five years or perhaps longer.
