Concentration In The Property And Liability Insurance Market By Line Of Insurance, Edward Nissan, Regina Caveny
Concentration In The Property And Liability Insurance Market By Line Of Insurance, Edward Nissan, Regina Caveny
Journal of Actuarial Practice (1993-2006)
This paper uses an National Association of Insurance Commissioners (NAIC) 1995 data set to examine the concentration of property and liability insurance by line of insurance in the U.S. The primary measure of concentration used is the Herfindahl index. The largest 100 affiliates are divided into three largest sets of 20, 30, and 50. We find that the homeowners line is the most concentrated line and commercial auto physical damage is the least concentrated line, with the top 20 affiliates commanding the largest between-set and within-set contributions.
Nonmedical Limits In Individual Life Insurance, James B. Ross, Shalini E. Perumpral
Nonmedical Limits In Individual Life Insurance, James B. Ross, Shalini E. Perumpral
Journal of Actuarial Practice (1993-2006)
This paper shows data that illustrate the substantial variation among nonmedical schedules and the dramatic increase in their amount limits from 1972 through 1992. Coefficients of variation are analyzed for several data subsets. We find that the variation of schedules in the sample of all firms has increased throughout the 1972-1992 period for issue ages up to 30, but has declined for issue ages beyond 30 during the 1982-1992 period. For the non-New York and stock companies our statistical tests indicate an increase in the variability of schedules over the full period 1972 to 1992.
