An. Berger et al., THE COEXISTENCE OF MULTIPLE DISTRIBUTION-SYSTEMS FOR FINANCIAL SERVICES - THE CASE OF PROPERTY-LIABILITY INSURANCE, The Journal of business, 70(4), 1997, pp. 515-546
Property-liability insurance is distributed through a direct-writer sy
stem, where agents represent one insurer, and an Independent-agency sy
stem, where agents represent several insurers. Independent-agency insu
rers have higher costs than direct writers. The market-imperfections h
ypothesis attributes the coexistence of the two types of insurers to i
mpediments to competition, while the product-quality hypothesis holds
that independent-agency insurers provide higher-quality services. We m
easure cost efficiency and profit efficiency for property liability in
surers and find strong support for the product-quality hypothesis, imp
lying that independent-agency insurers produce higher-quality outputs
and are compensated by higher revenues.
