We present a fast and simple tree model to price simple and exotic options in Markov Regime Switching Model (MRSM) with multi-regime. We modify the trinomial tree model of Boyle (1986) by controlling the risk neutral probability measure in different regime states to ensure that the tree model can accommodate the data of all different regimes at the same(More)
In this paper we summarize the main idea and results of Yuen and Yang (2009, 2010a, 2010b) and provide some results on pricing of Parisian options under the Markov regime-switching model (MRSM). The MRSM allows the parameters of the market model depending on a Markovian process, and the model can reflect the information of the market environment which(More)
This paper focuses on the meaning and process of collaboration, particularly in the area of research and clinical practice. Much has been written about the existing gaps between research and the practice of nursing; however, action research is one mechanism that allows these elements to be drawn together. Research developed through collaborative(More)
