Governors' Party Affiliation and Unions
利用美国近三十年州长选举的断点回归设计，研究州长党派（民主党或共和党）对工人加入工会、工会工人工作时间和收入的因果影响，发现党派归属并无显著作用。
Employing a regression discontinuity (RD) approach on gubernatorial elections in the United States over the last three decades, this paper investigates the causal effects of governors' party affiliation (Democrat versus Republican) on unionization of workers, and unionized workers' working hours and earnings. Surprisingly, we find no significant impact from the party affiliation of governors on union membership and union workers' labor‐market outcomes.
