Abstract

We study a financial market where risk-neutral traders are endowed with a signal that perfectly reveals the direction (but not the exact amount) of the liquidation value of a normally distributed risky asset. The impact of order flow on prices is nonlinear with a bullish/bearish information structure, which is broadly consistent with empirical evidence. Also, private information is revealed quicker than in a strategic oligopoly.
