Political Parties and Labor-Market Outcomes: Evidence from US States
利用美国州长选举与人口调查数据，通过断点回归发现民主党州长增加了黑人相对于白人的年工作时长，缩小了种族收入差距。
This paper estimates the causal impact of the party allegiance (Republican or Democratic) of US governors on labor-market outcomes. I match gubernatorial elections with March Current Population Survey (CPS) data for income years 1977 to 2008. Using a regression discontinuity design, I find that Democratic governors cause an increase in the annual hours worked by blacks relative to whites, which leads to a reduction in the racial earnings gap between black and white workers. The results are consistent and robust to using a wide range of models, controls, and specifications.
