Mrázová and Neary (2017) introduce the notion of the Demand Manifold which expresses the relationship between the elasticity and curvature of a demand function. They argue that this determines many important comparative static properties of firm behavior. This paper gives necessary and sufficient conditions for two demand functions to have the same demand manifold and so to have similar comparative static properties.

需求函数和需求流形

Mrázová和Neary（2017）引入了需求流形的概念，该概念表达了需求函数的弹性和曲率之间的关系。他们认为，这决定了企业行为的许多重要的比较静态属性。本文给出了两个需求函数具有相同需求流形并因此具有相似比较静态特性的必要和充分条件。
