Many studies report lower academic productivity among women. But are women less likely to get their research published in the first place? The evidence for potential gender bias in publication and impact is mixed. This article examines the gender dimension of scientific publication in international relations (IR) based on submission data for Journal of Peace Research for the period 1983–2008. It examines the gender gap in submissions and explores whether the perceived merit of a research paper is affected by the gender of the authors and reviewers. It also investigates whether the gender of the first author influences citation counts. The data show a clear but declining gender gap. They do not indicate any significant gender bias in publication success or citations.
