Urban poverty and the onset of the Coronavirus pandemic: Evidence from American cities
研究了美国城市贫困是否影响新冠疫情早期传播，以及出行限制政策是缓解还是加剧了这种影响。发现城市贫困增加与病例上升相关，且居家令在贫困分布不均的城市反而加速了传播。
This article investigates empirically whether urban poverty in American cities has affected the spread of COVID‐19 at the early onset of the pandemic and whether such an effect was mitigated or amplified by mobility restriction policies. Using ACS data combined with data on mobility and confirmed cases, and after addressing bias arising from measurement error and unobserved confounders, we find that an increase in urban poverty is associated with a rise in COVID‐19 cases. stay‐at‐home orders are found to be ineffective and instead reinforce the speed of contagion in cities where poverty is less evenly distributed across neighborhoods.
