1. Can we restart the economy with a two-day work week?

2. They& #39;re not attacking epidemiologists or playing stupid games with data. Just the simplest underlying models needed to explore a straightforward proposal:
Let& #39;s restart the economy with a 2-day work week, and stay at home the other 5 days of the week to reduce transmission.

3. Cyclic, scheduled closure makes a ton of sense, both from control purposes (control is hard!) and from scheduling purposes.
4. The problem is, I don& #39;t think it will work.
5. The model manages to just get R down below the critical threshold of 1. There is very little margin for error.
6. The estimate of R=2.4 during active days seems reasonable.
What I& #39;m concerned about is the estimate of R=0.3 for lockdown days. (It& #39;s attributed to the Imperial College study but I& #39;m not seeing it on a quick re-read; can someone point it out to me? https://www.imperial.ac.uk/media/imperial-college/medicine/sph/ide/gida-fellowships/Imperial-College-COVID19-NPI-modelling-16-03-2020.pdf)">https://www.imperial.ac.uk/media/imp...

7. To my knowledge, the best estimate of R during lockdown comes from the Chaolong Wang study of 25,000+ Wuhan cases. https://www.medrxiv.org/content/10.1101/2020.03.03.20030593v1

8. But that paper also estimates a much larger value of =3.86 before lockdown. I think this is anomalously high compared to other studies, but it is concerning that the two-day work week scheme wouldn& #39;t work under the Wang et al. parameters that give us R=0.3 for lockdown.
9. My bigger concern is that even if the R=2.4 estimate is right for active days, I am dubious that we in the West can get anywhere near Wuhan& #39;s R=0.3 on lockdown days, especially if interspersed with active work days. And if we don& #39;t, the two-day work week allow epidemic growth.
10. I suppose there is always the 1-day week. That would work even with R=0.7. As a teenager I thrilled at Philip José Farmer& #39;s Dayworld trilogy where people lived one day a week for the good of the collective. This could be our chance to embrace that dystopian life.
