We document that the emergence of markets for single-name credit default swap (CDS) contracts adversely affects equity market quality. The finding that firms with traded CDS contracts on their debt have less liquid equity and less efficient stock prices is robust across a variety of market...

Using a broad panel of NYSE-listed stocks between 1983 and 2004, we study the relation between institutional shareholdings and the relative informational efficiency of prices, measured as deviations from a random walk. Stocks with greater institutional ownership are priced more efficiently, and...

We study the information content in monthly short interest using NYSE-, AMEX-, and NASDAQ-listed stocks from 1988 to 2005. We show that stocks with relatively high short interest subsequently experience negative abnormal returns, but the effect can be transient and of debatable economic...

We analyze allocations to institutional and retail investors in 441 initial public offerings (IPOs). In addition to the well known favorable first-day returns, we show that institutions also obtain more allocations in IPOs with better long-term performance. We find that initial institutional...

I analyze market order execution quality using order-based data reported in accordance with SEC Rule 11Ac1-5. These data facilitate a comprehensive investigation of multiple dimensions of execution quality, including measures of costs and speed, for large samples of common stocks on Nasdaq and...

We study pre-trade transparency by looking at the introduction of NYSE's OpenBook service that provides limit order book information to traders off the exchange floor. We find that traders attempt to manage limit order exposure: They submit smaller orders and cancel orders faster. Specialists'...
