In this paper, we investigate a linear-quadratic(LQ) optimal control problem for partially observed forward-backward stochastic systems with random jumps, where the observation’s drift term is linear with respect to the state x and control variable v. In our model, the observation process is no longer a Brownian motion but a controlled stochastic process driven by Brownian motions and Poisson random measures,which also have correlated noises with the state equation. Applying a backward separation approach to decompose the state and observation, we overcome the problem of cyclic dependence of control and ***, the necessary and sufficient conditions for optimal control are derived. We also obtain the feedback representation of optimal control and provide two special cases to illustrate the significance of our ***, we also provide a financial application to demonstrate the practical significance of our results.

In this paper, we investigate a kind of partial information linear-quadratic optimal control problem driven by a backward stochastic differential equation, where the state equation and the cost functional contain diffusion terms. Using maximum principle, we derive the corresponding Hamiltonian system, which is a conditional mean-field forward-backward stochastic differential equation. By the backward separation approach and the filtering technique, we get two Riccati equations, and a backward and a forward optimal filtering equations. Then a feedback form of optimal control is obtained. We also extend the control problem to the case of mean-field backward stochastic differential equation under partial information. A corresponding feedback form of optimal control is also obtained.

This paper is concerned with a linear-quadratic stochastic Stackelberg differential game, where players have asymmetric roles, with one leader and one follower in the context of two-person game. It is required that the information available to the follower is a sub-σ-algebra of the one of the leader. By maximum principle and optimal filtering, a feedback Stackelberg equilibrium of the game is given. A special example is used to elaborate the result.

提级问责是党和国家用以矫正常态治理失效的一种手段,一定程度上可以破解突发事件应急管理难题,提高应急管理绩效。以2014—2022年29个被提级调查的突发事件为研究对象,采用模糊集定性比较分析方法(fsQCA)探析事故类型、事故严重程度、权力类型、责任类型、领导批示及舆论压力六个具体条件变量相互依赖对提级问责结果的复杂影响机制。基于委托—代理理论和注意力理论,构建“事件属性—权责结构—注意力分配”的三维分析框架,解释何种变量组合共同影响了提级问责结果。研究发现:事故类型和事故严重程度是影响突发事件提级问责结果的必要条件和充分条件;提级问责结果的影响路径共有五种,具有“殊途同归”效果,具体概括为外部舆论助推型、内部压力主导型和内外联合驱动型三种模式。结果表明,事件属性是影响突发事件提级问责结果的核心要素,权责结构是影响突发事件提级问责结果的结构化因素,上级领导和公众的注意力分配是影响突发事件提级问责结果的主要力量。为了有效发挥提级问责机制应对突发事件的效能,应注重提升提级问责的制度化和法治化水平。
