Although this epistemology can partially explain the re-creation of the Chinese legal system during the earlier period of reform and opening up, it fails to provide a comprehensive picture of the present complex situation. Taking as an example the changes in the Chinese legal profession during reform and opening up, this study employs quantitative data and empirical methods to explore the multiple dynamic impacts of the state, the market and society on the Chinese legal system. The study also proposes a theoretical framework of ＂structural constraints＂ on legal change. Since reform and opening up, the Chinese legal system has undergone a transition from state dominance to multi-agent interactions between the state, the market, society, and the legal system itself.展开更多

In this paper, the authors assume that the surplus process is the sum of a compound Poisson process and an independent Wiener process. The dual of the jump-diffusion risk model under a threshold dividend strategy is discussed. The authors derive a set of two integro-differential equations satisfied by the expected total discounted dividend until ruin. The cases where profits follow an exponential or mixtures of exponential distributions are solved. Applying the key method of the Laplace transform, the authors show how the integro-differential equations are solved. The authors also discuss the conditions for optimality and show how an optimal dividend threshold can be calculated as well.展开更多
