Avoiding another lockdown by separating the elderly from the young?

Based on their ongoing research and simulations, Andrea Ichino, Carlo Favero and Aldo Rustichini argue in a recent op-ed that targeted measures to minimize close contact between the elderly and the young could bring down significantly the number of infections among higher age groups. This in turn could save lives, prevent the health care system from collapse and allow more economic activity to continue. Proposed measures include separated use of public transport, more home working arrangements for higher age groups and time slots reserved for elderly people at supermarktes.
