CREDIT DEFAULT SWAPS – WEAPON OF MASS DESTRUCTION OR RELIABLE INDICATOR?

Credit Default Swaps (CDS) are said to increase systemic vulnerability, but they also serve as an ex‐ante indicator of default probabilities, more finely‐tuned and more responsive than ratings agency reports. And they provide a useful mechanism for trading risk and an incentive for good management by businesses and governments.     

臭氧-活性炭-过氧化氢法处理染料废水的研究

采用臭氧-活性炭-过氧化氯法对染料废水进行了处理．考察了添加剂、废水初始pH值对染料废水中COD、色度、挥发酚及氰化物去除率的影响。结果表明，臭氧-活性炭-过氧化氢联合的方法对染料废水中COD、色度、挥发酚及氰化物的去除很有效，去除率均达96％以上。最佳条件下，COD、挥发酚达国家三级排放标准：色度、氰化物达国家一级排放标准。     

构建我国生态税收体系的路径选择——基于可持续发展视角

鉴于目前严峻的自然资源和环境污染状况，我国很有必要在短期内实行生态税制改革。但是考虑到我国的经济发展水平和税制的稳定性，我国的生态税制改革应循序渐进，分三阶段展开。第一阶段生态税制改革的任务是完善现行的生态税收政策，即在保持现行税制框架稳定的基础上对一些政策细则进行调整。第二阶段实行排污费的彻底费转税改革，开征环境污染税。第三阶段引入碳税，充分借鉴OECD国家的税率制定、税收收入返还方式、税收优惠等政策经验，在实现二氧化碳减排目标的同时尽量降低碳税对国民经济和高能耗企业造成的冲击。

Options Trading Based on the Forecasting of Volatility Direction with the Incorporation of Investor Sentiment

Using options price data on the Taiwanese stock market, we propose an options trading strategy based on the forecasting of volatility direction. The forecasting models are constructed with the incorporation of absolute returns, heterogeneous autoregressive-realized volatility (HAR-RV), and proxy of investor sentiment. After we take into consideration the margin-based transaction costs, the results of our simulated trading indicate that a straddle trading strategy that considers the forecasting of volatility direction with the incorporation of market turnover achieves the best Sharpe ratios. Our trading algorithm bridges the gap between options trading, market volatility, and the information content of investor overreaction.

Individuals’ Trading Prior to Earnings Announcements

This paper investigates the relationship between individuals’ net trading and stock price movements before and after annual earnings announcements for the Taiwan Stock Exchange. We conduct an event study on the effects of pre‐event individual trade imbalances on pre‐ and post‐announcement abnormal returns. With a unique and comprehensive dataset, we accurately classify executed orders by aggressiveness of order price. The evidence indicates that while individuals, as a group, are not informed about impending earnings announcements, individuals who place aggressive orders are informed as their net trading coincides with contemporaneous and future stock returns. Aggressive individuals lose their edge during the financial crisis. More importantly, the advantage (disadvantage) for individuals who adopt aggressive (passive) orders weakens when foreign institutions own concentrated equity in firms. We also find that net individual trading contains information about abnormal returns that either past returns or volume does not subsume. Controlling for past returns, trading volume and volatility, or using an alternative measure of net individual trading does not change our conclusions.     

交易透明度对证券场外交易信息效率的影响

黑池交易系统（Dark Pools）是美国近年发展较快的非公开交易平台, 其信息透明度较低,可提供匿名交易的服务,并由此实现信息的非公开传递。通过扩展后验信念收敛速率的模型来描述不同交易透明度下场外市场的信息显示速率, 发现私人信息与公共信息共存有利于信息更快地显示,因而私人信息渠道与公共信息渠道共存有利于提升信息效率,由此解释了非公开交易平台的价值,也为我国场外市场的分层发展提供可行建议.
