摘要
This paper provides an existence theorem for a class of infinite-dimensional non-convex problems arising in symmetric and asymmetric information models. Sufficient conditions for monotonicity of solutions are also given. The proofs are very simple and rely on rearrangement techniques and the concept of supermodularity. Several applications to insurance are given. (c) 2005 Elsevier B.V. All rights reserved.
