 (April 6). Our analyses show that many socially costly NPIs can be avoided through strong
 rapid testing policies.
 
+Two of the most contentious NPIs concern schools and mandates to work from home. In many
+countries, schools switched to remote instruction during the first wave, so did Germany.
+After the summer break, they were operating at full capacity with increased hygiene
+measures, before being closed again from mid-December onward. Some states started opening
+them gradually in late February, but operation at normal capacity did not resume until
+the beginning of June. Figure~\ref{fig:school_scenarios} shows the effects of different
+policies regarding schools starting after Easter, at which point rapid tests had become
+widely available. We estimate the realized scenario to have essentially the same effect
+as a situation with closed schools. Under fully opened schools with mandatory tests,
+total infections would have been 6\% higher; this number rises to 20\% without tests.
+These effect sizes are broadly in line with empirical studies (e.g. \citet{Vlachos2021,
+Berger2021}, see Section~\ref{subsec:model_validation} for a comparison). In light of the
+large negative effects school closures have on children and parents \citep{Luijten2021,
+Melegari2021}---and in particular on those with low socio-economic status---these results
+in conjunction with hindsight bias suggest that opening schools combined with a testing
+strategy would have been beneficial. In other situations, and particular when rapid test
+are not available at scale, trade-offs may well be different.

+Figure~\ref{fig:workplace_scenarios} shows that with a large fraction of workers
+receiving tests, testing at the workplace has larger effects than mandating employees to
+work from home. Whether the share of workers working at the usual workplace is reduced
+or increased by ten percent changes infection rates by 2.5\% or less in either
+direction. Making testing mandatory twice a week---assuming independent compliance by
+employers and workers of 95\% each---would have reduced infections by 23\%. Reducing
+rapid tests offers by employers to the level of March would have increased infections by
+13\%.

 Figure~\ref{fig:work_scenarios_detailed} shows the effects of different work policies on
 the infections in the general population. We compare four scenarios with our baseline
 scenario: Keeping the share of workers having physical work contacts the same as in our

+\textbf{Main point}
+\vskip1ex
+
+\noindent
+Our main methodological contribution is to calibrate a very detailed and flexible agent
+based model to a long time series of data during the CoVid-19 pandemic. Our core
+substantive result is the quantitative importance of rapid testing as a supplement to
+NPIs. Due to the slow vaccine roll-out in most countries, this will remain topical for
+some time.
