In this paper, the interactions between a large informed trader (IT, for short) and a high-frequency trader (HFT, for short) who can anticipate the former's incoming order are studied in an extended Kyle's model. Equilibria under various specific situations are discussed. We find that, in...

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...

This paper develops a market microstructure model with asymmetric information in order to quantify the influence which practical decision rules have on asset prices. The users of practical decision rules have incomplete information at their disposal and trade in a market with both fully informed...

This paper examines how technological innovations drive fast trading investment for both speculators and exchanges and their impact on market. The negative externality of the speed acquisition from fast speculators can result in excessive investment, which is intensified as speculators' speed...

Speed hierarchy not only motivates fast trading competition on less precise information but also renders slower traders more informative. As a result, endogenous speed acquisition in equilibrium affects how information is produced and spread. When information diffusion is characterized by its...

This paper develops a finite-period model of rational bubbles where trade of an asset takes place through a chain of middlemen. We show that there exists a unique equilibrium, and a bubble can occur due to higher-order uncertainty. Under reasonable assumptions, the equilibrium price is...

This study shows that the information content of FX transactions depends on the identity of market participants. Using spot FX transactions of a major Australian bank, we find that central banks have the greatest price impact, followed by non-bank financial institutions (NBFIs) such as hedge...

Traders differ in speed and their speed differences matter. I model strategic interactions induced when high frequency traders (HFTs) have different speeds in an extended Kyle (1985) framework. HFTs are assumed to anticipate incoming orders and trade rapidly to exploit normal-speed traders'...

Will arbitrage capital flow into markets experiencing shocks, mitigating adverse effects on price efficiency? Not necessarily. In a dynamic model with privately informed capital-constrained arbitrageurs, price efficiency plays a dual role, determining both the profitability of new arbitrage and...

In a market with informationally connected traders, the dynamics of volume, price informativeness, price-volatility, and price-impacts are severely affected by the number of information linkages every trader experiences with his neighbors. We show that in the presence of information linkages...
