C. Gollier et H. Schlesinger, ARROWS THEOREM ON THE OPTIMALITY OF DEDUCTIBLES - A STOCHASTIC-DOMINANCE APPROACH, Economic theory, 7(2), 1996, pp. 359-363
We provide a new proof for the optimality of deductible insurance that
does not depend on the expected-utility hypothesis. Our model uses on
ly first- and second-degree stochastic dominance arguments.
