  • 详情 CHINESE BOND MARKET AND INTERBANK MARKET
    Over the past twenty years, especially the past decade, China has taken enormous strides to develop its bond market as an integral step of financial reform. This paper aims to provide the most up-to-date overview of Chinese bond markets, by highlighting two distinct and largely segmented markets: Over-the-Counter based interbank market, and centralized exchange market. We explain various bond instruments traded in these two markets, highlighting their inherent connection with the banking system, and many multi-layer regulatory bodies who are interacting with each other in an intricate way. We also covers the credit ratings and rating agencies in Chinese market, and offer an account of ever-rising default incidents in China starting 2014. Finally, we discuss the recent regulatory tightening of shadow banking since late 2017 and its impact on bond investors, and the forces behind the internalization of Chinese bond markets in the near future.
  • 详情 以生存分析方法构造信用风险模型
    现阶段,学术界主要通过结构模型和简化模型对信用风险进行建模, 并以此为基础对信用衍生品定价。由于信用风险评估的实质是度量在 一定时间内发生违约事件的概率,与流行病学领域的生存分析有相似 之处,本文借用生存分析常用方法重新定义信用风险模型,并在此基 础上构建信用衍生品定价模型。本文着重介绍生存分析基本函数、生 存分析常用参数模型和半参数模型在信用风险度量中的应用。
