利用对偶方法,我们证明了未定权益无差别价格 π 的几个重要性质。潜在的市场模型是非常普遍的,数学公式是基于问题自然产生的二元性。特别地,无差别价格 π 被证明是由效用函数引起的Orlicz空间上的一种凸风险度量。
Using duality methods, we prove several key properties of the indifference price π for contingent claims. The underlying market model is very general and the mathematical formulation is based on a duality naturally induced by the problem. In particular, the indifference price π turns out to be a convex risk measure on the Orlicz space induced by the utility function.
