Despite the introduction of several restrictive regulations in the past decades, evidence of gender wage discrimination is still commonly found in the Netherlands. This study aims to create a better understanding of this phenomenon by linking it with the firm size-wage effect, a commonly observed relationship between firm size and wages. An extensive Mincerian wage equation is estimated using a generalized linear model with Huber-White standard errors on yearly panel data. The results indicate the existence of a significant interaction effect between the FSWE and gender wage discrimination in the Netherlands
