First, Do No Harm: Financial Conflicts in Medicine
(joint with Chris Parsons and Nathan Tefft)
What it's about: We find that when a doctor is paid by a pharmaceutical firm he is more likely to prescribe that firm's drug, both relative to close substitutes and even generic versions of the same drug. This payment-prescription sensitivity is stronger among men and in high-corruption states.

Short Selling Risk
(joint with Adam Reed and Matt Riggenberg). forthcoming at the Journal of Finance

Invited Presentations: AFA Meeting (Chicago, 2012)



Know thy Neighbor
(joint with Arzu Ozoguz and Sean Wang), Journal of Financial and Quantitative Analysis (2017)

What it's about: We find evidence that firms located in geographic industry clusters have more efficient prices: they are more likley to be covered by analysts, held by mutual funds which already have a holding in the cluster and exhibit less price delay with respect to industry information.

Anchoring on Credit Spreads
(joint with Casey Dougal, Chris Parsons and Ed Van Wesep), Journal of Finance (2015)

What it's about:We find that the interest rate a firm happens to borrow at last time influences its current borrowing costs. The evidence suggests that borrowers
and lenders use past terms as "anchors" (Tversky and Kahneman [1974]), and that these
seemingly irrelevant reference points influence future transactions.
Invited Presentations: NBER Corporate Finance Meeting (Chicago, 2011); University of Michigan (2011); UC Irvine (Merage, 2011); SFS Cavalcade (2011); University of Washington (Foster, 2011); Florida State University (2011); AFA Meeting (Chicago, 2012), University of Oregon (Lundquist, 2012), Brigham Young University (Marriott, 2013), Tilburg University (2012), Erasmus University (Rotterdam, 2012), Duisenberg School of Finance (Amsterdam, 2012), Indiana University (Kelley, 2013)

The Sum of All FEARS: Investor Sentiment and Asset Prices
(joint with Zhi Da and Paul Gao), Review of Financial Studies (2015)

What it's about:We use search volume (for terms like "recession" and "inflation") to measure investor sentiment in real time and link investor sentiment to market-level returns, volatility and fund flows.
Invited Presentations:NBER Behavioral Economics Meeting (Chicago, 2010); Western Finance Association Meeting (Victoria, 2010)
Data: Daily FEARS updated through 12/30/2011

Network Position and Productivity: Causal Evidence from Editor Rotations
(joint with Jonathan Brogaard and Chris Parsons), Journal of Financial Economics (2014)

What it's about: We find that when a journal rotates to a new editor, members of the editor's network publish twice as many articles in the editor's journal. These "inside articles" have significantly higher ex post citation counts, suggesting that personal associations are used to improve selection decisions.
Invited Presentations: New York University (Stern, 2011); Harvard University (HBS, 2011); University of Washington (Foster, 2011); University of Alberta (2011); Florida State University (2011), HKUST (2012), Singapore Management University (2012), University of Oklahoma (2012), Nanyang Technological University (2012), UC Irvine (Merage, 2012)

The Price of a CEO's Rolodex (joint with Paul Gao and Chris Parsons), Review of Financial Studies (2013)

Invited Presentations: Western Finance Association Meeting (Victoria, 2010)

Journalists and the Stock Market
(joint with Casey Dougal, Diego Garcia and Chris Parsons), Review of Financial Studies (2012), RFS Best Paper Award (1st Prize)

What it's about: We find that individual journalists of a well-known Wall Street Journal column influence aggregate market prices. Because these journalists are randomly assigned to the column (the day they write has nothing to do with market returns), we can identify a causal effect of media on aggregate market prices.

Invited Presentations: University of Pennslyvania (Wharton, 2011); Boston College (2010); University of Arizona (2010); INSEAD (2010); University of Toronto (2010); FM/UC-Davis Napa Valley Conference (2011); SFS Cavalcade (Michigan, 2011)

How are Shorts Informed? Short Sellers, News and Information Processing (joint with Adam Reed and Matt Riggenberg), Journal of Financial Economics (2012)

What it's about: We find short-sellers have much more profitable trades on news days than off news days, evidence that short-sellers' skill may be coming from their ability to process information in news events.
Invited Presentations: Utah Winter Finance Conference (2010); American Finance Association Meeting (2011, Denver); University of Southern California (Marshall, 2011)

Friends with Money
(joint with Paul Gao and Chris Parsons), Journal of Financial Economics (2012), JFE Best Paper Award (2nd Prize)

What it's about: When firm employees share a personal connection with bank employees, loan terms are more favorable (lower rates and fewer covenants), and the firm experiences better ex-post performance (measured by credit quality and stock market returns).

The Causal Impact of Media in Financial Markets (joint with Chris Parsons), Journal of Finance (2011)

What it's about: Because it's challenging to disentangle the causal impact of media reporting from the impact of the events being reported, we solve this problem by comparing the behaviors of investors with access to different (local) media coverage of the same information event.
Invited Presentations: Financial Research Association Conference (Las Vegas, 2009); Columbia University (2009); NBER Behavioral Economics Meeting (Cambridge, 2009); Texas A&M (2009); Western Finance Association Meeting (Victoria, 2010; WINNER: Best Empirical Finance Paper)

In Search of Attention
(joint with Zhi Da and Paul Gao), Journal of Finance (2011)

What it's about: We use Google search volume for stock tickers (e.g. "AAPL") as a new, direct measure of investor attention.
Invited Presentations: PanAgora Asset Management Crowell Prize Competition (WINNER: First Prize, 2010); UC Irvine (Merage, 2009); NBER Market Microstructure Meeting (Cambridge, 2009); University of Georgia (2009); Chicago Quantitative Alliance Academic Competition (WINNER: First Prize, 2009); AFA Meeting (San Francisco, 2009); Fifth Annual Behavioral Science Conference (Yale, 2009); CEPR Summer Symposium (2010, Gerzensee)

Assessing the Temporal Variation of Macroeconomic Forecasts by a Panel of Changing Composition
(joint with Charles Manski and Jared Williams), Journal of Applied Econometrics (2010)

What it's about:We use the Survey of Professional Forecasters to call attention to the inference problem that arises under changing panel composition. For example, when the average GDP forecast rises, we do not know whether all forecasters raised their expectations of GDP or whether optimistic forecasters entered the survey panel and pessimistic ones left (or both).
