摘要翻译：
在一个金融市场的不完全半鞅模型中，我们考虑了几个规避风险的金融代理人，他们协商一束未定权益的价格。假设代理人的风险偏好以凸资本需求为模型，定义和分析了代理人的需求函数，并提出了局部均衡价格的概念。除了存在唯一性的充分条件外，我们还证明了均衡价格对于代理人风险偏好的不规范是稳定的。

英文摘要：
In an incomplete semimartingale model of a financial market, we consider several risk-averse financial agents who negotiate the price of a bundle of contingent claims. Assuming that the agents' risk preferences are modelled by convex capital requirements, we define and analyze their demand functions and propose a notion of a partial equilibrium price. In addition to sufficient conditions for the existence and uniqueness, we also show that the equilibrium prices are stable with respect to misspecifications of agents' risk preferences.
