The purpose of this study is to investigate the relation between investor protection and firm liquidity. We posit that less protective environments lead to wider bid-ask spreads and thinner depths because they fail to minimize information asymmetries. The Hong Kong equity market provides a unique opportunity to compare liquidity costs across distinct investor protection environments, but still within a common trading mechanism and currency. Our empirical findings verify that firm liquidity is significantly affected by investor protection. Regression and matched-sample results show that Hong Kong-based equities exhibit narrower spreads and thicker depths than their China-based counterparts.
