Abstract
A Theil's entropy index utilizing premiums written as units is employed to measure trends in concentration of the largest 200 property-casualty companies in the United States between 1985 and 1993 based on Best's Insurance Report data. Each of the indexes confirms that concentration trends experienced no increase for the whole period for all 200 firms, the top 20, and subsets of lower ranked companies. Significant differences are observed, however, between groups of companies for the same period.
