Despite ample investigation into the influence of ambient temperature on behavior, and especially on criminal activity, little research exists on the impact of temperature on police behavior. As such, this analysis tests the “heat hypothesis” over 5 years of traffic stops by the City of Pittsburgh Police Department. Across a range of specifications, police officers are more likely to issue traffic citations when temperatures are warmer—holding constant driving behavior—and the magnitude of the increase is comparable to citation rate discrepancies between black and white drivers.

热点：温度，警察行为和执法

尽管对环境温度对行为特别是对犯罪行为的影响进行了充分的调查，但很少有人研究温度对警察行为的影响。因此，这项分析检验了匹兹堡市警察局在过去5年的交通停靠中的“热量假说”。在各种规范中，警官在温度较高时（保持恒定的驾驶行为）更可能发出交通事故的引证，其增加幅度可与黑人和白人驾驶员的引证率差异相媲美。
