This study examines the effect of option volume relative to stock volume (O/S) on market response to earnings surprises. The market reaction per unit of earnings surprise is lower for firms that have high O/S prior to earnings announcement than for firms with low O/S prior to earnings...

This paper assesses the importance of the role of prices as aggregators of private information in the Samp;P 500 futures market. We estimate primitive parameters of the Hellwig (1980) noisy rational expectations model, when both prices and terminal values are observable. The variance-covariance...

XVA is a material component of a trade valuation and hence it must impact the decision to exercise options within a given netting set. This is true for both unsecured trades and secured/cleared trades where KVA and MVA play a material role even if CVA and FVA do not. However, this effect has...

The effect of self-default on the valuation of liabilities and derivatives (DVA) has been widely discussed but the effect on assets has not received similar attention. Any asset whose value depends on the status, or existence, of the firm will have a DVA. We extend Burgard&Kjaer (2011) to...

We provide an easy-to-use model that values derivatives for a privately informed agent. We introduce private forward prices that conveniently format private information for inclusion in a standard no-arbitrage framework. This framework yields simple expressions for the privately-informed value...

We derive a general expression for the value of information to a price-taking investor in a dynamic environment and provide a framework for its estimation. We study the value of both private and public information and break it down into its instrumental and psychic parts. To illustrate, we...

Early studies find that option introductions tend to raise the price of underlying stocks. More recent research indicates post-1980 option introductions are associated with negative abnormal returns in underlying stocks. Other studies document increased short-sale activities following option...

In a structural model for credit risk we endogenize inability to pay as a second independent reason for default besides overindebtedness. Inability to pay is triggered by rational behavior of incompletely informed outsiders. The firm needs to raise additional cash via secondary equity offerings...

This paper provides an up-to-date review and summary of the existing literature on the informational aspects of price processes. A common feature of these models is that prices reflect information that is dispersed among many traders. The paper begins by contrasting the Rational Expectation...
