Working Papers  

Analyst Proximity and Earnings Management,” with Yue Tang, 2012. (under initial submission at Journal of Financial Economics)


This paper explores the hypothesis that the geographical proximity of analysts to the firms they cover influences the earnings management of those firms. Using a unique, hand-collected database of analyst locations, we show that firms with a higher level of local analyst coverage manage their earnings less. These firms are less likely to overinvest and make empire-building acquisition bids. They also have better operating performance and lower risks. The results indicate that geographical proximity facilitates analysts’ monitoring by reducing monitoring cost.


Do Anomalies Exist Ex Ante?” with Lu Zhang, 2012. (revise and resubmit at the Review of Finance, presented in Western Finance Association Conference 2009)


The anomalies literature in capital markets research is based almost exclusively on average realized returns. In contrast, we construct accounting-based expected returns for dollar neutral long-short trading strategies formed on a wide array of anomaly variables, including book-to-market, size, composite issuance, net stock issues, abnormal investment, asset growth, investment-to-assets, accruals, earnings surprises, failure probability, return on assets, and short-term prior returns. Our findings are striking. Except for the value premium, cost of equity estimates differ drastically from average realized returns. If accounting-based costs of equity are reasonable proxies for expected returns, the evidence implies that returns of most anomalies are unexpected by the market, and that mispricing, not risk, is the main driving force of capital markets anomalies.


Divergence of Opinion, Arbitrage Costs and Stock Returns,” 2012. (under initial submission at the Journal of Business Finance and Accounting, presented in European Finance Association Conference 2006)


We develop a new proxy for divergence of opinion and examine how divergence of opinion affects cross-sectional asset returns for stocks with different arbitrage costs. We generalize Tauchen and Pitts’ (1983) Mixture of Distribution Hypothesis (MDH), which links asset volume and volatility in a way that derives a proxy for divergence of opinion among all investors. In our empirical analysis, we establish that the negative relation between divergence of opinion and future returns are especially pronounced for stocks with higher arbitrage costs, such as idiosyncratic risks, short sale costs, and other transaction costs.


“Social Connections and Corporate Bond Underwriting,” with Yue Tang, 2012.


This paper examines whether social connections between investment bank underwriters and bond issuers are an important channel for banks to obtain information advantage, which may allow banks to better evaluate issuers, and therefore charge lower fees and sell bonds at lower yields. We find that bank-issuer connections significantly reduce the fees and bond yields. Furthermore, the impact of social connections on the fees and yields is stronger for bonds with lower credit ratings and bonds that are not rated. These findings suggest that investment banks gain information advantage through social connections.


Stock Market Microstructure Measures of Information Asymmetry Are Related to Marketwide Information,” with Clara Vega, 2006.


In this paper, we show that adverse selection costs estimated using stock market data are also related to macroeconomic information, and that these measures do not necessarily proxy the degree of opaqueness of the firm but rather how sensitive firms are to macro shocks. Our results help explain the widely documented commonality in liquidity because commonality in adverse selection costs is an important source of liquidity co-movement. This explanation has been previously ruled out as Goodhart and O.Hara (1997, p. 102) summarize, “how could private information be expected to have a global impact?”  Similarly, Chordia, Sarkar and Subrahmanyam (2006, p. 93) mention that “adverse selection is unlikely to be a major issue in bond markets,” hence stock and bond market liquidity co-movement can’t be due to commonality in adverse selection costs. Contrary to this common wisdom, we document that adverse selection costs are also a source of co-movement across stocks and between stock and bond market liquidity.
