Fig. 5: High frequency treatment effects over a 7-month follow-up.

The figure plots the 7-day running mean treatment effects for each day during the 4-week intervention period and the subsequent 7-month follow-up period for each experimental arm, as estimated by Eq. (2). Dashed vertical lines represent each of the four messages delivered to the apartments. The yellow shaded area indicates local lockdowns due to the COVID-19 pandemic. Driscoll and Kraay's standard errors were used. Errors were not clustered, given that the randomization was performed at the apartment level.
