DescriptionThis dissertation is comprised of three essays that study behavioral finance and market microstructure.
The first essay models a game of individual day traders' interactions in a stock trading chat room and empirically tests the model's conclusions. Trading behaviors are analyzed in an Internet chat room with free entry but secure identity, and traders' interactions are modeled as a dynamic game with informed traders, momentum traders, arbitragers and noise traders. Three empirical predictions are generated in the model's equilibrium. The unique data set consists of stock trading chat room posts of more than 1,000 individual semi-professional day traders and their interactions and transactions are investigated in a time series. All the three predictions from the model's equilibrium are affirmed by empirical tests.
The second essay assesses the effects of the entire limit order book and analyzes the market impacts of the quotes in the Shanghai and Shenzhen Stock Exchange in China, where the stock market has a pure order-driven trading mechanism without market makers. Firstly, in the empirical modeling the limit order books, the structural vector autoregressive model of Hasbrouck (1991) is used and extended to incorporate more information beyond the inside quotes. Secondly, the market impact of stocks is also analyzed cross sectionally with market capitalization, tick frequency, turnover, average price, etc. Finally, the market impacts and order imbalance of small trades are distinguished. Small trades, usually linked with individual investors, have proportionally small market impact. Besides, the volume-weighted daily order imbalances of small trades and next-day's and contemporaneous daily returns are negatively related with each other. This is in accordance with the 'pain theory' of the individual traders.
The third essay investigates microstructure characteristics of the Credit Default Swap (CDS) market. During the sample period, April 2006 -- March 2008, CDS are traded on the over-the-counter (OTC) market, through brokers' voice-based or electronic-based systems. The study analyzes CDS spread, trade-to-quote ratio, bid-ask spread, the frequency that the orders fall between the quotes, and the relationship between the order imbalance and the daily change of CDS spread.
