We find that men's performance is significantly affected by psychological momentum, while women's is not. This result is robust to different specifications and estimation strategies. Our results are in line with evidence in the biological literature that testosterone, which is known to enhance performance of both men and women, commonly increases following victory and decreases following loss only among men. Implications of our findings for contest design are also discussed. KW - psychological momentum KW - contest KW - gender differences KW - performance ER -
