Many believe that a bubble was behind the high prices of Internet stocks in 1999-2000, and that short-sale restrictions prevented rational investors from driving Internet stock prices to reasonable levels. Using intraday options data from the peak of the Internet bubble, we find no evidence that...

The Nasdaq market came under intense pressure from regulators and class-action lawsuits following allegations of tacit collusion by Christie and Schultz (1994). This paper examines the changes in tranactions costs on Nasdaq over January 1993 through June 1996 using 16 million trades in 30...

SOES bandits are individual investors who day-trade primarily through Nasdaq's Small Order Execution System (SOES). They attempt to predict short-term price movements of Nasdaq stocks by observing trades and changes in market maker quotes. We find that they usually hold positions for only a few...

We examine syndicates for 1,638 IPOs from January 1997 through June 2002. We find strong evidence of information production by syndicate members. Offer prices are more likely to be revised in response to information when the syndicate has more underwriters and especially more co-managers. More...

Numerous studies document long-run underperformance by firms following equity offerings. This paper shows that underperformance is very likely to be observed ex-post in an efficient market. The premise is that more firms issue equity at higher stock prices even though they cannot predict future...

This is the first paper to examine the microstructure of how mispricing is created and resolved. We study dual class-shares with equal cash-flow rights, and show that a simple trading strategy exploiting gaps between their prices appears to create abnormal profits after transactions costs. Trade...

During five weeks over March and April 2000, internet stocks declined 58%. Almost $700 billion in capitalization was lost. This sudden collapse has been attributed to an increase in the supply of shares from lock-up expirations and equity offerings. In this paper, I show that internet stocks...

Our paper examines the impact of geographic location on liquidity for U.S. rural- and urban-based companies. Even after adjusting for size and other factors, rural firms trade much less, are covered by fewer analysts, and are owned by fewer institutions than urban firms. Trading costs are higher...

Two explanations are commonly offered for the large number of recent IPOs by Internet firms: that they are rushing to go public when Internet stock prices are irrationally high, and that they are trying to grab market share in an industry with large economies of scale. We examine the actions of...

The NASDAQ multiple dealer market is designed to produce narrow bid-ask spreads through competition for order flow among individual dealers. However, we find that odd-eighth quotes are virtually non-existent for 71 of 100 actively traded NASDAQ securities, including Apple Computer and Lotus...
