英文摘要:
We investigate the effects of the social interactions of a finite set of agents on an equilibrium pricing mechanism. A derivative written on non-tradable underlyings is introduced to the market and priced in an equilibrium framework by agents who assess risk using convex dynamic risk measures expressed by Backward Stochastic Differential Equations (BSDE). Each agent is not only exposed to financial and non-financial risk factors, but she also faces performance concerns with respect to the other agents. Within our proposed model we prove the existence and uniqueness of an equilibrium whose analysis involves systems of fully coupled multi-dimensional quadratic BSDEs. We extend the theory of the representative agent by showing that a non-standard aggregation of risk measures is possible via weighted-dilated infimal convolution. We analyze the impact of the problem\'s parameters on the pricing mechanism, in particular how the agents\' performance concern rates affect prices and risk perceptions. In extreme situations, we find that the concern rates destroy the equilibrium while the risk measures themselves remain stable.

中文摘要:
我们研究了一组有限代理人的社会互动对均衡定价机制的影响。非交易基础上的衍生产品被引入市场,并由代理人在均衡框架下定价,代理人使用倒向随机微分方程(BSDE)表示的凸动态风险度量来评估风险。每个代理人不仅面临财务和非财务风险因素,而且还面临其他代理人的绩效问题。在我们提出的模型中,我们证明了一个平衡点的存在性和唯一性,该平衡点的分析涉及完全耦合的多维二次BSDE系统。我们扩展了代表代理理论,证明了通过加权扩张下卷积可以实现风险度量的非标准聚集。我们分析了问题参数对定价机制的影响,特别是代理人的绩效关注率如何影响价格和风险感知。在极端情况下,我们发现关注率破坏了均衡,而风险度量本身保持稳定。
