Recent Developments in Workmen's Compensation Insurance Rate Making

The rate making program adopted by the National Council on Compensation Insurance in 1925 and described in the paper captioned "The 'Permanent' Rate Making Method adopted by The National Council on Compensation Insurance" (Proceedings, Vol. XII, page 253) is, with two exceptions, the procedure now being followed by the National Council in the establishment of rates for workmen's compensation insurance. This paper will deal only with the amendments to the established program, both of which amendments have resulted from a study of experience by size of risk. The first relates to expense and the second, to pure premium or loss cost.
