The proposed cost function is C(I) = {co, Co + Cl + kl, if! = 0; if I > 0; (22) where Cl is a per-claim fixed cost covering costs to estimate damage and related costs. It is shown that a policy with a partially disappearing deductible is optimal in this case: 1(0) = {O,x - D, if 0 :5 L; if 0> L, (23) with L > D. With this policy, nuisance claims less than L - D are not paid simply because the equilibrium contingent prices for these 0 E [D, L] - which include fixed costs - exceed the shadow prices charged by consumers.
