Just finished this research with Daron Acemoglu, Victor Chernozhukov & Mike Whinston (I know, lucky for such an awesome eclectic team!)

I'm exhausted from many late-night meetings, after kids in bed, so happy to see it out.

Where to start? 

COVID-19 has one incredibly striking feature. Its severity varies strongly with age, hitting the elderly hard, but sparing most of the young. 

We are talking ORDERS of MAGNITUDE.  Estimates vary, but there is much agreement on this. 2/nFor example, Fergurson's numbers for mortality

  0.1%  20-49

  1%     50-64

  6%    65+

You can find different and lower numbers, but the pattern is similar. 

To us these are facts to grapple with, not to be ignored.Before I continue, let me leave this here.
