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 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,...

This paper studies the relation between order imbalances and daily returns of individual stocks. Our tests are motivated by a theoretical framework, whose distinguishing feature is that it explicitly considers how market makers with inventory concerns dynamically accommodate autocorrelated...

This paper analyzes the effects of a finite tick size and the practice of 'payment-for-order-flow' on competition between NYSE and non-NYSE market makers. Due to the presence of non-specialist market makers, order submitters find that their NYSE orders are sometimes executed at better than...

Do order flows in index derivatives play an informational role? Weekly index put order flow on the International Securities Exchange positively and robustly predicts weekly S&P 500 index returns. This result obtains mainly for net put buying and is stronger in high VIX periods and in periods...

A significant fraction of firms' financing occurs via public debt markets. Accordingly, we investigate whether financial statement characteristics and other variables that predict equity returns also predict corporate bond returns. Profitability, asset growth, and equity market capitalization...

We propose that the volatility of order flow is a proxy for costs of information asymmetry, as order flow volatility varies positively with parameters that also influence adverse selection costs of trading. Empirically, order flow volatility is significantly higher prior to earnings or merger...

Given the evidence that the level of liquidity affects asset returns, a reasonable hypothesis is that the second moment of liquidity should be positively related to asset returns, provided agents care about the risk associated with fluctuations in liquidity. Motivated by this observation, we...
