How does informed trading affect liquidity in limit order markets, where traders can choose between market orders (demanding liquidity) and limit orders (providing liquidity)? In a dynamic model, informed trading overall helps liquidity: A higher share of informed traders (i) improves liquidity as proxied by the bid-ask spread and market resiliency, and (ii) has no effect on the price impact of orders. The model generates other testable implications, and suggests new measures of informed trading.
