The Probability of Informed Trading (PIN) is a widely used indicator of information asymmetry risk in the trading of securities. Its estimation using maximum likelihood algorithms has been shown to be problematic, resulting in biased estimates, especially in the case of liquid and frequently...

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 simple microstructure model to demonstrate that VCV is strictly increasing in the...

We meticulously scrutinize the widely acknowledged measures of the Probability of Informed Trading (PIN) and the Volume-Synchronized Probability of Informed Trading (VPIN), initially posited by David Easley et al., which have achieved considerable eminence within the realm of financial academia....

The purpose of this paper is to introduce the R package InfoTrad for estimating the proba- bility of informed trading (PIN) initially proposed by Easley et al. (1996). PIN is a popular information asymmetry measure that proxies the proportion of informed traders in the market. This study...

I study a generalized OLG economy where asymmetrically informed agents have arbitrary investment horizons. As horizons increase, the age-adjusted risk aversion of investors fall, and the risk transfer from forced liquidators into voluntary buyers drops. Two equilibria coexist for long enough...

The paper contrasts theories that explain diverse belief by asymmetric private information (in short PI) with theories which postulate agents use subjective heterogenous beliefs (in short HB). We focus on problems where agents forecast aggregates such as profit rate of the Samp;P500 and our...

Can prices convey information about the fundamental value of an asset? This paper considers this problem in relation to the dynamic properties of the fundamental (whether it is constant or time-varying) and the structure of information available to agents. Risk-averse traders receive two...
