利用美国邮政服务和 Zillow 的数据，我们量化了 Covid-19 对美国城市内部和城市之间的移民模式和房地产市场的影响。我们发现两个关键结果。首先，在美国大城市内，家庭、企业和房地产需求已从密集的中央商务区 (CBD) 转向密度较低的郊区。我们将此称为“甜甜圈效应”，反映了活动从市中心向郊区环线的转移。其次，虽然观察到的重新分配发生在城市内部，但我们没有看到跨城市的重大重新分配。也就是说，很少有证据表明活动大规模地从美国大城市转移到较小的地区城市或城镇。我们通过指出大流行后的工作模式通常会是混合的来合理化这些发现，工人通常每周三天通勤到他们的营业场所。这种通勤水平低于大流行前，使得郊区相对更受欢迎，但过于频繁，不允许员工离开雇主所在的城市。
Using data from the US Postal Service and Zillow, we quantify the effect of Covid-19 on migration patterns and real estate markets within and across US cities. We find two key results. First, within large US cities, households, businesses, and real estate demand have moved from dense central business districts (CBDs) towards lower density suburban zip-codes. We label this the “Donut Effect” reflecting the movement of activity out of city centers to the suburban ring. Second, while this observed reallocation occurs within cities, we do not see major reallocation across cities. That is, there is less evidence for large-scale movement of activity from large US cities to smaller regional cities or towns. We rationalize these findings by noting that working patterns post pandemic will frequently be hybrid, with workers commuting to their business premises typically three days per week. This level of commuting is less than pre-pandemic, making suburbs relatively more popular, but too frequent to allow employees to leave the cities containing their employer.
