The main results are as follows. First, the equilibrium price differential is not a linear function of the highest quality valuation (accident probability) and the maximum and minimum quality differentials. Second, a high quality insurance firm does not always receive greater equilibrium expected profit, even if its average cost is the same as that of a low-quality insurance firm. Finally, a change in the highest quality valuation has an ambiguous effect on the equilibrium expected profit differential., International Journal of Economics and Business Modeling, 1(2), pp.12-14; 2010}, pages = {12--14}, title = {The Vertical Differentiation Model in the Insurance Market}, volume = {1}, year = {2010} }
