Economies won’t be able to recover after shutdowns

Posted on by

Citizens seem to be clamoring for shutdowns to prevent the spread of COVID-19. There is one major difficulty, however. Once an economy has been shut down, it is extremely difficult for the economy to recover back to the level it had reached previously. In fact, the longer the shutdown lasts, the more critical the problem is likely to be. China can shut down its economy for two weeks over the Chinese New Year, each year, without much damage. But, if the outage is longer and more widespread, damaging effects are likely.

A major reason why economies around the world will have difficulty restarting is because the world economy was in very poor shape before COVID-19 hit; shutting down major parts of the economy for a time leads to even more people with low wages or without any job. It will be very difficult and time-consuming to replace the failed businesses that provided these jobs.

When an outbreak of COVID-19 hit, epidemiologists recommended social distancing approaches that seemed to be helpful back in 1918-1919. The issue, however, is that the world economy has changed. Social distancing rules have a much more adverse impact on today’s economy than on the economy of 100 years ago.

Governments that wanted to push back found themselves up against a wall of citizen expectations. A common belief, even among economists, was that any shutdown would be short, and the recovery would be V-shaped. False information (really propaganda) published by China tended to reinforce the expectation that shutdowns could truly be helpful. But if we look at the real situation, Chinese workers are finding themselves newly laid off as they attempt to return to work. This is leading to protests in the Hubei area.

My analysis indicates that now, in 2020, the world economy cannot withstand long shutdowns. One very serious problem is the fact that the prices of many commodities (including oil, copper and lithium) will fall far too low for producers, leading to disruption in supplies. Broken supply chains can be expected to lead to the loss of many products previously available. Ultimately, the world economy may be headed for collapse.

In this post, I explain some of the reasons for my concerns. Continue reading →

It is easy to overdo COVID-19 quarantines

Posted on by

We have learned historically that if we can isolate sick people, we can often keep a communicable disease from spreading. Unfortunately, the situation with the new coronavirus causing COVID-19 is different: We can’t reliability determine which people are spreading the disease. Furthermore, the disease seems to transmit in many different ways simultaneously.

Politicians and health organizations like to show that they are “doing something.” Because of the strange nature of COVID-19, however, doing something is mostly a time-shifting exercise: With quarantines and other containment efforts, there will be fewer cases now, but this will be mostly or entirely offset by more cases later. Whether time-shifting reduces deaths and eases hospital care depends upon whether medical advances are sufficiently great during the time gained to improve outcomes.

We tend to lose sight of the fact that an economy cannot simply be shut down for a period and then start up again at close to its former level of production. China seems to have seriously overdone its use of quarantines. It seems likely that its economy can never fully recover. The permanent loss of a significant part of China’s productive output seems likely to send the world economy into a tailspin, regardless of what other economies do.

Before undertaking containment efforts of any kind, decision-makers need to look carefully at several issues:

  • Laying off workers, even for a short time, severely adversely affects the economy.
  • The expected length of delay in cases made possible by quarantines is likely to be very short, sometimes lasting not much longer than the quarantines themselves.
  • We seem to need a very rapid improvement in our ability to treat COVID-19 cases for containment efforts to make sense, if we cannot stamp out the disease completely.

Because of these issues, it is very easy to overdo quarantines and other containment efforts.

In the sections below, I explain some parts of this problem.

Easily overlooked issues regarding COVID-19

Posted on by

We read a lot in the news about the new Wuhan coronavirus and the illness it causes (COVID-19), but some important points often get left out.

[1] COVID-19 is incredibly contagious.

COVID-19 transmits extremely easily from person to person. Interpersonal contact doesn’t need to be very long; a taxi driver can get the virus from a passenger, for example. The virus may be transmissible even before an infected person develops symptoms. It may also be transmissible for a few days after a person seems to be over the virus; it is possible to get positive virus tests, even after symptoms disappear. Some people may have the disease, but never show symptoms.

[2] The virus likely remains active on inanimate surfaces such as paper, plastic, or metal for many days.

There haven’t been tests on the COVID-19 virus per se, but studies on similar viruses suggest that human pathogens may remain infectious for up to eight days. Some viruses that only infect animals can survive for more than 28 days. China is reported to be destroying paper currency from the hardest hit area, because people do not want to accept money which may have viruses on it. Clearly, surfaces in airplanes, trains and buses may also harbor viruses, long after a passenger with the virus has left, unless they have been thoroughly wiped down with disinfectant.
