Coronavirus: Out of Many, One

What the US Federal Government and the States Should Do to Fight the Coronavirus

1. The Current Situation in US States

In the previous graph I showed countries with 50 cases or more. Now I’m showing countries with 1000 cases or more. There’s 181 countries with coronavirus cases, or over 90% of the total.
I use absolute numbers (total cases) instead of relative numbers (cases per capita) because here we’re trying to assess whether there’s an outbreak or not. Absolute numbers show if there’s a cluster and how big it is. Per capita doesn’t show this. Eg, if Liechtenstein had 5 cases, it would look like a national emergency in relative numbers, but it’s nothing. When assessing outbreaks, absolute numbers are more relevant. When assessing how bad the situation was a posteriori, relative numbers will be more relevant. The other reason is that relative numbers are much harder to process.

The Coronavirus Kills Republican-Leaning Voters More

This graph shows how flu epidemics impact 600 US cities based on their size. Bigger cities are more to the right and have bigger circles, so the small bubbles on the left show smaller cities. The vertical axis represents how concentrated the flu season is in particular weeks. We can see that big cities concentrate at the bottom right, which means their epidemics are spread over many weeks. Conversely, the smaller cities are, the more they tend to be at the top left, meaning their epidemics are concentrated in fewer weeks. This is believed to be caused partially by the fact that there is always some transmission, and hence ongoing herd immunity, in urban areas. This won’t be the case with the coronavirus, since there’s no herd immunity yet, but what this does illustrate is that smaller cities don’t get spared because they’re small. They do get hit, and when they do, the epidemic also hits hard.

So Which One Is Better, Mitigation or Suppression?

This is one of the more complex graphs in this entire article, so let’s explain it a bit. Red dots are cities that had weaker social distancing measures than the average city. Green dots are cities that had stronger social distancing measures than the average. The line shows the trend: more mortality meant less employment after the pandemic. The grey area shows the confidence interval: the true trend is likely to be within that area, meaning that it’s extremely likely that it was a downward trend. Because the virus hit the East Coast first, cities in the West had time to learn from cities in the East and take stronger, faster measures. That, however, generates a bias. There are more biases, such as that wealthier cities could manage the healthcare crisis better, but might be hit worse by the virus, or cities with more density could be hit more. So researchers controlled for factors such as density, wealth, population… Their controls were the 1910 agriculture employment share, 1910 manufacturing employment share, 1910 urban population share, 1910 income per capita, and log 1910 population.

The Price of a Life

Notes: some people have asked me how it is possible that the value of some people’s lives is comparable to the size of GDP. GDP is broadly the value created in a year, not the total wealth we have. The total wealth we have in the US is approximately $1 million per person on average, which means the US’s wealth is ~$320 trillion. That does not account for the wealth in terms of life, but puts the cost of $15 trillion in lives into perspective. Also I haven’t talked about the costs to the economy of the Dance phase of the Suppression strategy, once heavy social distancing measures subside. That’s because, if done well, countries can “dance” with only a small subset of measures that don’t cost much: testing, contact tracing, quarantines, isolation, hygiene education, and travel bans. Note finally that a suppression strategy would cost all of society but would benefit older people more, as they are the ones most likely to be saved by these measures. As such, they are a transfer of wealth from all of society towards our seniors, who in the US tend to vote Republican.
