Under fairly basic rationales, this paper provides a more general microstructure model of price quotation in an order driven market. Specifically, as an extension of Handa and Schwartz (1996), we decompose the equilibrium of the bid-ask spread, which is derived as a function of the weighted...

This paper evaluates the informational content of an open limit order book by studying its role in explaining long run volatility. We separate liquidity-driven (transitory) volatility from information-driven (long run) volatility using a dynamic state-space co-integration model for ask and bid...

We study price formation in securities markets, using the sequential trade framework of Glosten and Milgrom [7]. This paper makes one basic methodological advance over previous research on sequential securities trading: we allow traders to choose from n trade sizes in a multi-period market,...

We present a model in which there is uncertainty about realization of a risky asset value for an informed trader. We introduce two states such that in the "narrow" state the informed trader has better information than in the "wide" state. Then, we show that the informed trader in the wide state...

This study examines the effect of Regulation Fair Disclosure (FD) on the relevance of company-sponsored conference calls. Measuring relevance by a conference call's ability to improve analyst forecast accuracy and consensus, I find larger improvements in both variables during the period...

Quarterly earnings conference calls are becoming a more pervasive tool for corporate disclosure. However, the extent to which the market embeds information contained in the tone (i.e. sentiment) of conference call wording is unknown. Using computer aided content analysis, we examine the...
