Many proxies of illiquidity have been used in the literature that relates illiquidity to asset prices. These proxies have been motivated from an empirical standpoint. In this study, we approach liquidity estimation from a theoretical perspective. Our method explicitly recognizes the analytic...

We study the effect of options trading volume on the value of the underlying firm after controlling for other variables that may affect firm value. The volume of options trading might have an effect on firm value because it helps to complete the market (allocational efficiency) and because the...

Previous studies of Treasury market illiquidity span short time-periods and focus on particular maturities. In contrast, we study the joint time-series of illiquidity for different maturities over an extended time sample. We also compare time series determinants of on-the-run and off-the-run...

This paper studies cross-sectional variations in stock trading activity for a comprehensive sample of NYSE/AMEX and Nasdaq stocks over a period of thirty-six years. Our theoretical framework indicates that trading activity depends on the extent of liquidity trading, the mass of informed agents,...

We provide a model in which irrational investors trade based upon considerations that are not inherently related to fundamentals. However, because trading activity affects market prices, and because of feedback from security prices to cash flows, the irrational trades influence underlying cash...

Market efficiency, the timely incorporation of information into prices, remains a central and controversial issue in finance. The short-horizon predictability of returns from past order flows is an inverse indicator of efficiency. We analyze this predictability for NYSE stocks that traded every...

Executive compensation has increased dramatically in recent times, but so has trading volume and individual investor access to financial markets. We provide a model in which some managers obfuscate financial statements in order to extract additional compensation. Owing to a lack of...

Given the lack of any clear evidence on the informational contributions of market intermediaries vis-agrave;-vis their clients in the extant literature, an important but unanswered question is whether intermediaries behave as passive traders or whether they actively seek and trade on information....

We study the joint time-series of daily liquidity in government bond and stock markets over the period 1991 to 1998. Innovations in liquidity are positively and significantly correlated across stock and bond markets. Further, order imbalances in the stock market impact bond and stock liquidity,...

We study the consumption-investment problem of an agent with constant relative risk aversion (CRRA) preferences who possesses private information about the future prospects of a stock. We examine the value of the information to the agent by comparing the utility equivalent with and without the...
