AI 中文总结
该研究扩展有限参与模型,允许不同时间偏好系数但相同风险厌恶系数的交易者,给出确保拉德纳均衡存在的参数限制,还给出确保交易者长期生存的进一步参数限制。
AI 中文摘要
我们扩展了巴萨克和库奥科(1998年)的有限参与模型,以允许具有不同时间偏好系数但相同恒定相对风险厌恶系数的交易者。我们的主要结果给出了确保拉德纳均衡存在的参数限制。作为应用,我们给出了确保所有交易者长期生存的进一步参数限制。
英文摘要
Foster and Viswanathan (1996) extend the discrete-time setting of Kyle (1985) to multiple informed traders who have partial information about the stock's terminal dividend. We resolve two long-standing open problems in this literature. First, we prove that an equilibrium exists in the setting of Foster and Viswanathan (1996). Second, as the number of trading times goes to infinity, we prove that the discrete-time equilibrium converges to the continuous-time equilibrium already proven to exist in Back, Cao, and Willard (2000).
