Short-sale constraints are prevalent in many financial markets and have been actively adjusted by regulators to tackle various problems in markets. However, theories of the impact of short-sale constraints on market liquidity and information quality are largely absent. In this paper, we extend Liu and Wang (2013) to study this impact in the presence of information asymmetry, inventory risk, and imperfect competition among market makers. In contrast to Diamond and Verrecchia (1987), we show that shortsale ban decreases bid price, increases ask price, implying an increase in bid-ask spread. In addition, short-sale constraints increase the volatility of bid-ask spreads. The presence of asymmetry information can further magnify the adverse impact of short-sale constraints on market liquidity. On the other hand, the presence of shortsale constraints may increase investors’ incentive to produce more precise information and thus improve aggregate information quality.
