We perform a comprehensive investigation of the illiquidity premium in international stock markets. We examine several established liquidity measures in 45 countries for the years 1990–2020. Our findings provide convincing evidence that liquidity pricing depends strongly on firm size. Although the premium is globally present, it exists only among microcap stocks, which have negligible economic significance. Outside the microcap universe, virtually no liquidity effect can be observed.
