We analyze the impact of women on corporate boards of directors on product quality. We innovate firstly by integrating the broad but fragmented research on the topic, offering a first simultaneously testing of a larger set of variables identified to be significant in earlier studies. Second, we add alternative indicators of female representation in board of directors as a potential determinant of product quality. Third, we use evaluation scores of goods by the nonprofit foundation “Stiftung Warentest” as a quality indicator, thus adding to a regionally diversified evidence. We find a significant positive effect of female board directors on product quality.
