I calibrate a Multi-Risk SIR model on the covid pandemic to analyze the impact of the age-specific confinement and PCR testing policies on incomes and mortality. Two polar strategies emerge as potentially optimal. The suppression policy would crush the curve by confining 90% of the population for 4...

The econometrics challenges are presented, in particular the problem of multiple equilibria and some solutions used in the literature are exposed. We...
