We study the impact of the MeToo movement on coauthorships in economics, by analyzing NBER and CEPR working papers between January 2004 and December 2020. Compared to pre-MeToo levels, collaborations across genders increased: we estimate a 12.5% increase of women coauthors per 100 men-authored papers. However, the movement led to an overall decline in new coauthorships, with senior researchers reducing new collaborations, especially with junior authors. In particular, they reduced their new collaborations with junior women by an estimated 33% per 100 senior-authored papers. The Covid-19 pandemic partially reversed the first of these two trends.
