This study reveals previously undocumented geography-related diversity in information acquisition. Exploiting the Security and Exchange Commission (SEC)'s Electronic Data Gathering and Retrieval (EDGAR) server log, which tracks use by Internet Protocol (IP) address, we find that acquisition of...

Large orders, particularly from institutions, are quite common these days and hence there is interest to know if institutional trading has any bearing on the price effect associated with large trades. Recent empirical studies contradict earlier evidence of negative price effect on selling large...

Security indices are central to modern finance. Because corporate bonds trade infrequently – often less than once a month – corporate bond indices cannot rely exclusively on real time prices, and must instead estimate the value of the market portfolio. While commercial indices do this using...

We analyze how public disclosure of informed investors' trades results in manipulation, which in turn affects coordination and competition in a duopolistic setting. We show that disclosure always increases market efficiency but its effect on informed investors' profit is ambiguous. When informed...

How do banks choose their debt maturity structure when credit markets are subject to information frictions? This paper proposes a model of equilibrium maturity choice with asymmetric information and endogenous roll-over risk. We show that in the presence of public signals about firms'...

Internet message boards are inherently a world of cheap talk due to the anonymity of message authors. This paper investigates whether a pecuniary reputation system influences the adverse selection endemic to message boards. First, we find evidence that such a authors with high reputation scores...

I study the effect of public information disclosure in a market setting where private information acquisition exhibits strategic complementarity. To overcome the issue of equilibrium multiplicity, I introduce heterogeneous information cost and imperfect information on the cost distribution. The...

I show how irrational ideas and rumors can drive asset prices - not because anyone believes them, but because they are commonly known without being common knowledge. The phenomenon is driven by short-term market participants who are well-informed about the information that others have, and who...
