将Grossman（J Polit Econ 80：223-255，1972）的健康资本模型扩展为随机模型，我们分析了关于医疗保健功效的不确定性的存在如何影响个人的最优健康投资行为。使用吉尔博亚和Schmeidler（J数学经济学18：141-153，1989）的最大最小期望效用（MMEU）模型与多个先验，我们表明，代理人保留初始水平的健康资本，如果医疗保健的价格在一定范围内。我们还表明，无投资的范围扩大的程度的不确定性的上升。
Extending the Grossman (J Polit Econ 80:223-255, 1972) model of health capital into a stochastic one, we analyze how the presence of Knightian uncertainty about the efficacy of health care affects the optimal health investment behavior of individuals. Using Gilboa and Schmeidler's (J Math Econ 18:141-153, 1989) model of maxmin expected utility (MMEU) with multiple priors, we show that an agent retains the initial level of health capital if the price of health care lies within a certain range. We also show that the no-investment range expands as the degree of Knightian uncertainty rises.
