The single auction equilibrium of Kyle's (1985) is studied, in which noise traders may be partially informed, or alternatively they can be manipulated. Unlike Kyle's assumption that the quantity traded by the noise traders is independent of the asset value, we assume that the noise traders are...

This paper develops and tests hypotheses regarding the relationship between D&O insurance purchase and firm size, governance characteristics, and business risk, using a unique panel dataset on Canadian firms for years 1996-2005. The rich data permit examination of the determinants of insurance...

We analyze the imperfect competition among multiple informed traders in an economy with a risky asset whose liquidation value is private information and follows a mean-reverting process. The unique linear equilibrium has an analytic form and is explicitly analyzed. When there are more auctions...

We analyze a model of informed trading where an activist shareholder accumulates shares in an anonymous market and then expends costly effort to increase the firm value. We find that equilibrium prices are affected by the position accumulated by the activist, because the level of effort...

We propose a new approach to measuring informed trading in individual securities based on a portfolio optimization model for investors facing information and liquidity shocks. These shocks induce speculative and liquidity-motivated order flow, taking into account the price impact of trading. The...

We analyse a Kyle-type continuous-time market model in which liquidity trading is correlated with a noisy public signal that is released continuously. We show that, in contrast to the previous literature, Kyle's lambda, the price sensitivity to the order flow, can even be nonmonotonic, depending...

In this article, we extend the one-period model of Jain and Mirman (1999) for asset trading with two correlated signals to a two period model. We then prove the existence and uniqueness of the Bayesian linear equilibrium. Finally, we perform comparative statics analysis with respect to Kyle...

We propose the Volume Coefficient of Variation (VCV), the ratio of the standard deviation to the mean of trading volume, as a new and easily computable measure of information asymmetry in security markets. We use a microstructure model to demonstrate that VCV is strictly increasing in the...

By exploiting the exogenous reductions of analyst coverage due to closures and mergers of brokerage firms, I examine the causal impact of information asymmetry on insider trading. I find that corporate insiders' abnormal returns increase sharply after coverage reductions. This effect is stronger...

Aim. High Frequency Trading poses a large number of ethical questions. The purpose of this study is to examine the ethical perceptions of those who work inside the HFT industry.Method. The research consisted of a case study. Participants (N=30) were high frequency traders, algorithm developers,...
