We propose a new and direct measure of investor attention using search frequency in Google (Search Volume Index (SVI)). In a sample of Russell 3000 stocks from 2004 to 2008, we find that SVI (1) is correlated with but different from existing proxies of investor attention; (2) captures investor attention in a more timely fashion and (3) likely measures the(More)
We use daily Internet search volume from millions of households to reveal market-level sentiment. By aggregating the volume of queries related to household concerns (e.g., " recession, " " unemployment, " and " bankruptcy "), we construct a Financial and Economic Attitudes Revealed by Search (FEARS) index as a new measure of investor sentiment.

An additional connection to an executive or director outside the firm increases compensation by about $17,000 on average, more so for " important " members, such as CEOs of big firms. Pay-for-connectivity is unrelated to several measures of corporate governance, evidence in favor of an(More)

These rate concessions do not appear to reflect sweetheart deals. Subsequent firm performance, such as future(More)
Disentangling the causal impact of media reporting from the impact of the events being reported is challenging. We solve this problem by comparing the behaviors of investors with access to different media coverage of the same information event. We use zip codes to identify 19 mutually exclusive trading regions corresponding with large U.S. cities. For all(More)

/&rmnary circulation in isolated rabbit lungs. Am, J. Physiol. 1g6(2): 401-414. 1959.-A new method has been devised for measuring the compliance (volume change + pressure change) of the pulmonary arterial tree (down to the capil-laries), in isolated, Krebs-Ringer-perfused rabbit lungs. The lungs were suspended in a plethysmograph and inflated with NZO.(More)
Combining a database of short sellers' trading patterns with a database of news releases, we show that short sellers' trading advantage comes largely from their ability to analyze publicly available information. Specifically, the prior finding that short sellers' trades predict future negative returns (e. (2005)) is more than twice as strong in the presence(More)
We explore financial conflicts of interest faced by doctors. Pharmaceutical firms frequently pay physicians in the form of meals, travel, and speaking fees. Over half of the 334,000 physicians in our sample receive payment of some kind. When a doctor is paid, we find that he is more likely to prescribe a drug of the paying firm, both relative to close(More)
