Koji Shirai   ''A generalization of monotone comparative statics'' ( 2008, Vol. 3 No.39 )     In this paper, we generalize the lattice theoretical comparative statics by Li Calzi and Veinott, and Milgrom and Shannon. While their theorem is constructed on lattices, particularly on partially ordered sets, we do not require the antisymmetry on a binary relation defined on the set. On the basis of this result, we can deal with the comparative statics of constrained optimization problems, including the cases with nonlinear constraints, in a very intuitive, but considerably general fashion. Specifically, we can extend the gvalue order methodsh proposed by Antoniadou and Mirman and Ruble in the context of consumer problems with linear constraints. It is also worth noting that our results on the value order can be applicable for any comparative criterion as long as it is a complete preorder on the domain of the objective function.     Keywords: JEL: C6 - Mathematical Methods and Programming: General   Manuscript Received : Jul 26 2008   Manuscript Accepted : Aug 04 2008   This abstract has been downloaded 1730 times                The Full PDF of this paper has been downloaded 166541 times
