Heat and Observed Economic Activity in the Rich Urban Tropics
利用新加坡的时空移动数据，研究发现高温天气下人们更多前往有空调的工作场所、商场和学校，尤其是低收入居民，表明富裕城市可通过投资空调缓解高温对经济活动的负面影响，但可能加剧气候危机。
Abstract We use space- and time-resolved mobility data to assess how heat impacts Singapore, a rich city state and arguably a harbinger of what is to come in the urbanising tropics. Singapore’s offices, factories, malls, buses and trains are widely air conditioned, its public schools less so. We document increased attendance and commuting to workplaces, malls and the more air-conditioned schools on hotter relative to cooler days, particularly by low-income residents with limited use of adaptive technologies at home. Investment by rich cities may attenuate heat’s pervasive negative consequences on productive outcomes, yet this may worsen the climate emergency in the long run.
