Gender Differences in Cooperative Environments? Evidence from The U.S. Congress
利用美国众议院法案共同发起数据，发现民主党议员中性别对合作数量无显著影响，但女性法案更少获得跨党派支持；共和党女性则招募更多共同发起人并吸引更多两党支持，表明合作主要由共同利益驱动而非性别本身。
Abstract This paper uses data on bill co-sponsorship in the U.S. House of Representatives to estimate gender differences in cooperative behaviour. We find that among Democrats there is no significant gender gap in the number of co-sponsors recruited, but women-sponsored bills tend to have fewer co-sponsors from the opposite party. On the other hand, we find robust evidence that Republican women recruit more co-sponsors and attract more bipartisan support on the bills that they sponsor. We interpret these results as evidence that cooperation is mostly driven by a commonality of interest, rather than gender per se.
