We examine the private information associated with insider trades using a Chinese data set. Insider buys positively forecast individual stock returns and insider sales negatively forecast individual stock returns. Classifying insiders as corporate managers and institutional investors, we find...

We provide evidence concerning the use of historical cost (HCA) versus mark-to-market (MTM) accounting in regulating financial institutions. Accounting rules, through their interactions with capital regulations, alter financial institutions' trading behavior. The insurance industry provides a...

This paper studies the price discovery dynamics in an order-driven market. Based on the transaction data on individual stocks, the paper focuses on the study of the monthly evolution of normalized volatility ratios on Euronext Paris for the CAC40 stocks before and after the implementation of the...

This paper aims at testing for time-variations in herd behavior in stock markets. In particular, we analyze how investors' behavior differs between times of market turmoil and tranquil trading periods. Thereby, we take into account herding within a certain market as well as international...

Speeding up the exchange does not necessarily improve liquidity. The price quotes of high-frequency market makers are more likely to meet speculative high-frequency "bandits", thus less likely to meet liquidity traders. The bid-ask spread is raised in response. The recursive dynamic model...

If investors are differently informed about the payoff of market-traded securities, then the traditional market portfolio is not a relevant benchmark for testing the CAPM. Each investor appraises expected returns and builds his optimal portfolio conditionally on his information. Which proxy to...

It is a ubiquitous corporate governance phenomenon in many countries that shareholders pledge their ownership as collateral to obtain personal loans, while Chinese market provides a specific institutional background to study controlling shareholders. With a sample consisted of 21,921 firm-year...

It is a stylized fact that trade indicator models (e.g. Madhavan, Richardson, and Roomans (1997) and Huang and Stoll (1997)) underestimate the bid-ask spread. We argue that this negative bias is due to an endogeneity problem which is caused by a negative correlation between the arrival of public...

We develop an information risk measure (ECIN) based on the price discovery of large trades. As the price series of large trades and small trades are cointegrated, the price discovery of trades can be easily estimated via the vector error-correction model (VECM). Intuitively, we use the VECM to...
