Sick pay pays sick people to stay home but to defeat the virus we also want lots of healthy people to stay home. We also want to support people who are at home because they can’t find work. We can accomplish these goals by subsidizing work using services like Upwork or Mechanical Turk. Jobs on platforms like Upwork are the shovel-ready work of the 21st century. A 21st century jobs program would pay people to stay home and isolate, support people without work, and produce some useful output all at the same time.
More generally, how about paying people to take online courses? i.e. an income support program and a human capital investment program at the same time. Of course, not everyone would do well and people would cheat but think of these programs as a combination of paying people to isolate, maintaining aggregate demand and providing a source of income when low-wage restaurant and other service-jobs are declining but with a work requirement.
