Economic activity during extreme events
本文综述了利用商业交易数据和智能手机定位数据等新型精细数据，来量化极端天气、自然灾害等事件在小区域和短时间内的经济影响，并讨论了这些数据的局限与优势。
Abstract Although extreme weather events, natural disasters or infrastructure failures potentially have important economic effects, quantifying these effects over small areas and fine time intervals has been difficult because of the fairly coarse scales available in most data sources. This paper surveys the use of relatively new and finely grained data available from some commercial sources, particularly transaction data and smartphone location data, to improve our understanding of economic effects of events. I review the limitations and challenges involved in the use of these data as well as the potential benefits that they offer.
