英文摘要:
In this paper, we consider a num\\\'eraire-based utility maximization problem under constant proportional transaction costs and random endowment. Assuming that the agent cannot short sell assets and is endowed with a strictly positive contingent claim, a primal optimizer of this utility maximization problem exists. Moreover, we observe that the original market with transaction costs can be replaced by a frictionless shadow market that yields the same optimality. On the other hand, we present an example to show that in some case when these constraints are relaxed, the existence of shadow prices is still warranted.

中文摘要:
在本文中,我们考虑了在固定比例交易成本和随机捐赠条件下,基于数量的效用最大化问题。假设代理人不能卖空资产,并且被赋予严格正的未定权益,这个效用最大化问题存在一个原始优化器。此外,我们观察到,具有交易成本的原始市场可以被产生相同最优的无摩擦影子市场所取代。另一方面,我们举了一个例子来说明,在某些情况下,当这些约束条件放松时,影子价格的存在仍然是有理由的。
