2019年，一家天然气工厂发生火灾且气温创历史新低，导致密歇根州出现天然气紧急短缺。全州范围内的紧急短信警报要求家庭将恒温器调至65°F。我们利用密歇根州及周边四个州的高频智能恒温器数据，结合双重差分研究设计分析该请求的有效性，发现密歇根州家庭平均将恒温器设置降低了1.1度。研究还按家庭基准恒温器设置是否高于65°F的合规目标，以及民主党州长选举得票率，检验了响应度的异质性，结果表明无线紧急警报系统的使用对构建有效的应急响应至关重要。
英文摘要
In 2019, a fire at a natural gas plant and historically low temperatures caused an emergency shortage of natural gas in Michigan. A statewide emergency text alert asked households to turn thermostats down to 65°F. We analyze the effectiveness of this request using high-frequency smart-thermostat data from Michigan and four neighboring states. Using a difference-in-differences research design, we find that Michigan households reduced thermostat settings by 1.1 degrees on average. Our results suggest that the use of the wireless emergency alert system was critical in creating an effective emergency response. We examine heterogeneity in responsiveness by whether a household's baseline thermostat setting was above or below the compliance target of 65°F and by Democratic Party gubernatorial vote share.
