Some people have argued that lockdown measures were unnecessary, or ineffective. The data definitely leans the other direction, but there’s enough uncertainty in all this that I can at least consider that a serious possibility. That doesn’t mean we were wrong to use them; in the presence of high uncertainty, assuming the worst-case scenario is often the best strategy. Far better to overreact than underreact. And indeed, I’d say that right now we still can’t be confident enough that things are safe to really re-open most of the economy. Re-opening too early could make things far worse.

There’s another argument for re-opening the economy which seems far more seductive: What about the people harmed by the lockdowns? This massive unemployment is terrible too, isn’t it? In fact, what if we’re killing more people by unemployment than we are saving from the virus? The Mises Institute warns: “Unemployment Kills”. Others have speculated that the recession could cause more deaths than the virus.

But in fact, unemployment does not kill. The evidence on this is quite clear. Even in the Great Depression, with massive unemployment, terrible monetary policy, and only the most minimal social welfare measures in place, death rates did not increase. In fact, for all causes except suicide, death rates decrease during recessions—probably because pollution, traffic accidents, and work-related injury and illness go down. And the suicide rate increase isn’t enough to increase the overall death rate.

Of course, dying by suicide is not the same thing as dying from cancer—and indeed, they are most likely different people being affected in each case. So in that sense unemployment can kill people; but it typically saves more people than it kills. Almost any policy choice will cause some deaths and prevent others, so really the best we can do is look at the overall aggregate and see whether our QALY have gone up or down.

This doesn’t mean that we should go out of our way to have recessions in order to save lives; the number of lives saved is small and the loss in quality of life is probably large enough to compensate for it. (That’s why we use quality-adjusted life years after all.) But this recession isn’t arbitrary; it’s the result of trying to stop a global pandemic, so that we don’t have a repeat of what influenza did in 1918.

When the CDC says it’s okay to open back up, by all means, let’s do that. They have issued guidelines for what we need to do in order to make that happen. But until then, let’s trust in the experts—the epidemiologists who say that we still need lockdown measures, and the economists who agree that it’s worth the cost.
