Previous studies of the U.S. market regard short-term reversal as compensation for liquidity provision. However, we find that intraday reversal has no significant dependence on stock liquidity for the Chinese market. Hence, based on a stylized framework, we propose an alternative explanation:...

What drives intraday reversal? Previous studies of the U.S. market regard short-term reversal as compensation for liquidity provision. However, in this paper, we find that intraday reversal has no significant dependence on stock liquidity for the Chinese market. Hence, based on a stylized...

We analyze a nonlinear rational expectations equilibrium model with an ex post endogenous liquidity provision decision. Speed and information technology advantages allow endogenous liquidity providers (ELPs) to switch between limit and market orders after observing private information. This...

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 study theoretically explores the impact of market segmentation uncertainty on producers' production decisions and their subsequent effects on producers' profits, consumer surplus, and social welfare. This uncertainty creates a mismatch between the producer's supply and consumer demand,...

Information-based reinforcement learning is effective for trading and price discovery in limit order markets. It helps traders to learn a statistical equilibrium in which traders' expected payoffs and out-sample payoffs are highly correlated. Consistent with rational equilibrium models, the...
