We propose an exchange rate model which is a hybrid of the conventional specification with monetary fundamentals and the Evans-Lyons microstructure approach. It argues that the failure of the monetary model is principally due to private preference shocks which render the demand for money...

Are high–frequency traders (HFTs) informed? To address this question, we examine HFTs' activity in the call auction environment, where speed-related trading is limited and signal processing capacity becomes more relevant. To model the call market, we consider the Kyle (1989) rational...

Yes. By observing return reversals following unexpected responses to noisy public signals about market-wide common factors, we show that investors in the US equity market tend to over-respond to public signals for mature firms that are relatively easy to price—old, large, and dividend-paying...

We show evidence of a liquidity searching behaviour of informed investors in option listings, which was also found by Collin-Dufresne and Fos (2015) using stock markets. Nevertheless, and differently from Collin-Dufresne and Fos (2015), we find that the option bid-ask spread may be still a good...

We examine the effects of investor disagreement on price discovery using a recurring public information event in the highly liquid crude oil futures market, a market free of short-sale constraints. We show that prices reflect positive news within one-half second of trading, but continue to drift...

In this paper, we investigate the stock price behaviour of newly listed companies on the stock exchange market with an extremely high level of information asymmetry. We show a unique mechanism of how informed investors influence the stock prices before entering the market to consume abnormal...

We propose a rational model to explain time-series momentum. The key ingredient is word-of-mouth communication, which we introduce in a noisy rational expectations framework. Word-of-mouth communication accelerates information revelation through prices and generates momentum. Social interactions...
