In this paper we introduce inverse demand systems that include quadratic scale terms. These systems are similar to regular quadratic demand systems introduced by Howe, Pollak, and Wales. A unique feature of these specifications is that they maintain linear scale curves as a special case. For...

Mathematical programming models can incorporate multiple objectives. Shadow prices in such models reflect a mixture of all of the objectives. A procedure is implemented to develop decomposed shadow prices applicable to the individual objectives. The procedure is demonstrated in a GAMS...
