We develop a model of price formation in a dealership market where monitoring of the information flow requires costly effort. The result is imperfect monitoring, which creates profit opportunities for speculators who pick off "stale quotes". Externalities associated with monitoring give rise to...

We develop a model of price formation in a dealership market where monitoring of the information flow requires costly effort. The result is imperfect monitoring, which creates profit opportunities for speculators, who do not act as dealers but simply monitor the information flow and quote...

We analyze the costs and benefits of providing and using liquidity in a limit order market. Using a large and comprehensive data set which details the complete histories of orders and trades on the Vancouver Stock Exchange, we are able to model the order flow and measure market liquidity as it...

This paper analyzes order placement strategies in a limit order market. Traders submitting market or limit orders to the limit order book trade off the order price, the execution probability, and the winner's curse risk associated with different feasible order choices. Their optimal order...

Adverse Selection and Competitive Market Making: Empirical Evidence from a Pure Limit Order Market<p> Patrik Sandas<p> Review of Financial Studies, Volume 14, 2001, pp. 705-734

This article presents a new methodology for testing economic restrictions on the price schedules offered in a limit order book that are based on (i) break-even conditions for marginal limit orders and (ii) rational updating conditions for order book revisions over time. Using order flow data...

A call option price is always an increasing and convex function of the underlying asset price whenever the underlying asset price follows a diffusion whose volatility depends only on time and the concurrent asset price-a one-dimensional diffusion. We empirically examine how often the observed...

We re-examine the co-movements of index options and futures quotes first studied in Bakshi, Cao, and Chen (2000). We show that the frequency of quote co-movements that are inconsistent with standard option pricing models is significantly higher around option trades. We examine empirically two...
