The talk is about the research within SWECOV, a large research pogram on the COVID-19 pandemic. The program is built on a rich set of medical, social and economic microdata from Sweden and was started when I served on the Swedish Corona Commission. In the seminar, I will give three examples of concrete projects. The first escribes the inequaltites, along different social gradients, in the medical, social and economic outfalls of the pandemic. The second project analyzes how pandemic shocks affected outputs across individual firms in exposed sectors, and the earnings across individual workers in those sectors. The third project will gauge the real-world vaccine effectiveness estimated from a set of natural experiments associated with the roll-out of the vaccine — as opposed to the vaccine efficacy estimated from RCTs before vaccine approval.
