The comparative dynamics of the feedback form of the consumption and health-investment demand functions in the health capital model of Grossman (1972) are thoroughly scrutinized for their refutable results. The usual comparative dynamics expressions, to wit, the individual partial derivatives of the demand functions with respect to the parameters and state variables, are not refutable under the basic assumptions of the theory. As a result, sufficient conditions for their falsifiability are identified. In contrast, the heretofore unknown intrinsic comparative dynamics of the demand functions are shown to be characterized by a positive semidefinite matrix of generalized Slutsky-like terms.

格罗斯曼（Grossman，1972）的健康资本模型中的消费和健康投资需求函数的反馈形式的比较动态被仔细研究了其可辩驳的结果。在该理论的基本假设下，通常的比较动力学表达式（即需求函数相对于参数和状态变量的各个偏导数）是不可辩驳的。结果，确定了对其伪造的充分条件。相反，需求函数的迄今未知的内在比较动力学显示为具有广义Slutsky类项的正半定矩阵。
