This paper examines how risk in trading activity can affect the volatility of asset prices. We look for this relationship in the behavior of interest rate swap spreads and in the volume and interest rates of repurchase contracts. Specifically, we focus on convergence trading, in which...

We propose a theory of asset prices that emphasizes heterogeneous information as the main element determining prices of different securities. Our main analytical innovation is in formulating a model of noisy information aggregation through asset prices, which is parsimonious and tractable, yet...

Using a large sample of firms listed on the Korea Stock Exchange over the 1992-2002 period, this paper investigates a hitherto unexplored question of whether and how trading by foreign and domestic institutional investors improves the extent to which firm-specific information is incorporated...

We examine the well studied Day of the Week effect (DWE), which is for many authors the effect that the day of the week has on the daily differences of the general index (GI). We try to clarify differences between the DWE and the impact that the day has on the GI. We also examine the impact that...

These shocks induce speculative and liquidity-motivated order flow, taking into account the price impact of trading. The...

The overwhelming empirical support of the Efficient Market Hypothesis makes it one of the widely accepted understandings in modern economics. The internal contradiction, relating to the fact that if inefficiencies didn't exist, opportunists would not search for them, which would in turn give...

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...

The financial services industry is among the leading industries in IT-spending. Still, little research exists which investigates how IT influences the financial services sector. Against this background, we study how a technology which emerged within the last years affects securities trading:...

This paper investigates the patterns of directors' trades and returns around takeover announcements. We find that the pre-announcement net value (the difference between buy value and sell value) of directors' trading is positively related to acquirers' announcement period abnormal returns. This...
