Discretionary accruals are positively associated with stock returns at the aggregate level but negatively so in the cross section. Using Baker-Wurgler investor sentiment index, we find that a significant presence of sentiment-driven investors is important in accounting for both patterns. We...

We analyze in this study cause of herding in a stock market. Information cascades have often been considered as a primary choice. However, we propose alternative explanations in this study. Employing intraday order book data, we suggest including an alternative theory based on search cost of...

This paper studies a rational expectation equilibrium (REE) model of the delegated portfolio management in which the fund managers care about the relative performance. I show that, in the case of symmetric information, the relative performance does not matter since all the fund managers submit...

This paper develops an equilibrium model of speculative bubbles that can be used to explore the role of various policies in either giving rise to or eliminating the possibility of asset bubbles, e.g. restricting the use of certain types of loan contracts, imposing down-payment restrictions, and...

Over the past two decades, hedge fund activism has emerged as a new mechanism of corporate governance that brings about operational, financial and governance reforms to a corporation. Many prominent business executives and legal scholars are convinced that the entire American economy will suffer...

We propose a new approach to measuring informed trading in individual securities based on a portfolio optimization model for investors facing information and liquidity shocks. These shocks induce speculative and liquidity-motivated order flow, taking into account the price impact of trading. The...

Applying a recently developed approach, the paper estimates the daily arrival rates of buy and sell orders originated from different trading motives for each stock in a sample of NYSE-listed companies. Based on these arrival rates, it shows that stock return tends to continue on consecutive days...

We construct a measure of abnormal relative attention (ARA), reflecting unusual changes in attention paid to a stock by local relative to non-local investors, to measure local information advantages. An increase in this measure predicts higher returns in the short term. This predictive power is...
