The pandemic triggered a large, lasting shift to work from home (WFH). To study this shift, we survey full-time workers who finished primary school in twenty-seven countries as of mid-2021 and early 2022. Our cross-country comparisons control for age, gender, education, and industry and treat the United States mean as the baseline. We find, first, that WFH averages 1.5 days per week in our sample, ranging widely across countries. Second, employers plan an average of 0.7 WFH days per week after the pandemic, but workers want 1.7 days. Third, employees value the option to WFH two to three days per week at 5 percent of pay, on average, with higher valuations for women, people with children, and those with longer commutes. Fourth, most employees were favorably surprised by their WFH productivity during the pandemic. Fifth, looking across individuals, employer plans for WFH levels after the pandemic rise strongly with WFH productivity surprises during the pandemic. Sixth, looking across countries, planned WFH levels rise with the cumulative stringency of government-mandated lockdowns during the pandemic. We draw on these results to explain the big shift to WFH and to consider some implications for workers, organization, cities, and the pace of innovation.

这场大流行引发了大规模、持久的在家工作（WFH）转变。为了研究这一转变，我们调查了截至 2021 年中和 2022 年初在 27 个国家完成小学学业的全职工人。我们的跨国比较控制了年龄、性别、教育和行业，并将美国的平均值视为作为基线。首先，我们发现，在我们的样本中，在家办公的时间平均为每周 1.5 天，各个国家的情况差异很大。其次，雇主计划在疫情结束后平均每周在家办公 0.7 天，但工人想要 1.7 天。第三，员工平均每周享受 2 至 3 天在家办公、工资为 5% 的选择，其中对女性、有孩子的人和通勤时间较长的人的评价更高。第四，大多数员工对疫情期间在家办公的生产力感到惊讶。第五，纵观个人，随着疫情期间在家办公生产力的惊人增长，雇主对大流行后在家办公水平的计划大幅上升。第六，纵观各国，随着疫情期间政府强制实施的封锁措施日趋严格，计划在家办公的水平有所上升。我们利用这些结果来解释向在家办公的重大转变，并考虑对工人、组织、城市和创新步伐的一些影响。
