In September 2008, a six-year-old article about the 2002 bankruptcy of United Airlines' parent company resurfaced on the Internet and was mistakenly believed to be reporting a new bankruptcy filing by the company. This episode caused the company's stock price to drop by as much as 76 percent in...

We provide robust evidence of deviations from the Covered Interest Parity (CIP) relation since the onset of the crisis in August 2007. The CIP deviations exist with respect to different dollar interest rates and exchange rate pairs of the dollar vis-à-vis other currencies. The results show that...

We develop a new likelihood-based approach to sign trades in the absence of quotes. It is equally efficient as existing MCMC methods, but more than 10 times faster. It can deal with the occurrence of multiple trades at the same time, and noisily observed trade times. We apply this method to a...

We infer motives for trade initiation from market sidedness. We define trading as more two-sided (one-sided) if the correlation between the numbers of buyer- and seller-initiated trades increases (decreases), and assess changes in sidedness (relative to a control sample) around events that...

We show that equity markets are typically two-sided and that trades cluster in certain trading intervals for both NYSE and Nasdaq stocks under a broad range of conditions - news and non-news days, different times of the day, and a spectrum of trade sizes. By quot;two-sidedquot; we mean that the...

This paper examines the mechanism by which the incorporation of information into prices leads to cross-autocorrelations in stock returns. We present a simple model where trading on private information occurs first in the large stocks and is transmitted to small stocks with a lag. Such trading...

Does the presence of arbitrageurs decrease equilibrium asset price volatility? I study an economy with arbitrageurs, informed investors, and noise traders. Arbitrageurs face a trade-off between arbitrage and inference: they would like to buy assets in response to temporary price declines (the...

Ratios that indicate the statistical significance of a fund's alpha typically appraise its performance. A growing literature suggests that even in the absence of any ability to predict returns, holding options positions on the benchmark assets or trading frequently can significantly enhance...

Do investors confuse the quality of a firm with its attractiveness as an investment? If so, shares of well-run companies will be bid up too high and subsequently earn negative abnormal returns. Our analysis of Fortune magazine's annual survey of quot;America's Most Admired Companiesquot; for...

We examine how professional traders behave in two financial market experiments; we contrast professional traders' behavior to that of undergraduate students, the typical experimental subject pool. In our first experiment, both sets of participants trade an asset over multiple periods after...
