Seismonomics: Listening to the Heartbeat of the Economy
利用北京近20年连续地震仪记录数据,分离人类活动振动,构建日度振动指数来预测区域工业生产,该指数能紧密追踪商业周期波动,尤其在经济危机期间表现突出,为政策制定者提供高颗粒度经济监测新工具。
Abstract Seismometers continuously record a wide range of ground vibrations that are not necessarily related to earthquake activity, but are rather caused by human activity such as industrial processes and traffic. We isolate the human-made imprints from a huge data set made of nearly 20 years of continuously recorded seismic data in Beijing, China, and construct a new daily indicator, the Vibration Index, to forecast regional industrial production. We find that our indicator closely tracks business cycle fluctuations particularly during economic crises. Our results provide policymakers with a new tool to monitor the economy at a highly granular level.
