Extended Data Fig. 4: Pre- and Post-Stimulus Trends in Public Mobility.

a, Event study results of cross-neighbourhood mobility within Seoul, b, Event study results of cross-city mobility from non-Seoul, c, Weekly new infection rate per 100 K population of Seoul. Data are presented as coefficient values (point estimate) +/- SE. (n = 27,918 homogeneous trip groups with same O-D in each week). Panels a and b present temporal changes in commuting inflows to neighbourhoods in Seoul. In South Korea, the two days in the 18th week were Children’s Day and Mother’s Day, which are peak times for family trips and parent visits. However, the impact of these holidays on public mobility and seasonality is accounted for by the weekly fixed effects.
