We document, for a global sample, that firms with greater transparency (based on accounting standards, auditor choice, earnings management, analyst following and forecast accuracy) experience less liquidity volatility, fewer extreme illiquidity events and lower correlations between firm-level liquidity and both market liquidity and market returns. Results are robust to numerous sensitivity analyses, including controls for endogeneity and propensity matching. Results are particularly pronounced during crises, when liquidity variances, covariances and extreme illiquidity events increase substantially, but less so for transparent firms. Finally, liquidity variance, covariance and the frequency of extreme illiquidity events are all negatively correlated with Tobin's Q.
