The paper investigates whether multinational corporations (MNCs) operating in Portugal and Greece perform differently than domestic firms. Departures from normality of firms’ profitability motivated the use of quantile regression. The results suggest that ownership ties do not make a significant difference with respect to performance of firms in Portugal. Results are similar for firms in Greece. Only when firms in the upper quantiles of gross profits are compared, MNCs are found to significantly perform better than domestic firms. MNCs have to compensate for their liability of foreigness that in spite of their technological advantages they cannot persistently outperform domestic rivals. Copyright Springer 2005
