Only someone who had never visited China and seen the scale of the place woukd say such a thing. It's like saying I locked down all the termite colonies in Australia.
The U.S. is steering itself toward a year-or-more-long issue that has people fearfully avoiding stores, deliveries, workplaces, and the consequences of this will ricochet. A recession happens when people and businesses restrict spending and hiring, and that's exactly what this scenario causes in a chronic way.
But who knows? Maybe Gilead's experimental antiviral will be approved within a month or two, and maybe that will be enough to make people not fearful and regain economic confidence.
I do think there will be a point when going out becomes less of a concern and there will be a lot of pent up demand for travel. The recovery will likely be sharp (V-shaped).
To relate the strategy to that formal definition of a recession, if everybody stayed home for a month this quarter, we might lose 1/3 of the quarter’s GDP. But if that break is structured so that it’s expected and we resume normal activity afterward, then in the next quarter we would see the GDP “grow“ a ton, if only back to normal because people are working and spending for the full three months, and we would cleanly avoid this formal definition for a recession.
But people not doing stuff basically means a recession, if not depression is guaranteed.
