The growing area of "mathematical social sciences" has provided valued insights for several disciplines, but a key aspect of this development desperately needs help from mathematicians who are skilled in dynamical systems. Namely, although "change" obviously is a central feature for all of the social sciences, it is not clear how it should be modeled. Indeed, in a real sense, this article is a call for help; it is an appeal for more people from the dynamical systems community to become involved. What makes the challenge attractive is that, once the appropriate dynamics are discovered, they most surely will involve features that differ from what we currently see in the literature. To introduce what causes some of the complexities of these areas, results and difficulties associated with price dynamics are described. As it will become clear, much less is known about how prices change than the reader might have expected.
