Crikey has recently published thought-provoking pieces by Adam Schwab on the cost of a lockdown. It is important to assess all benefits and costs of policy decisions: lives saved by the restrictions must be weighed against their human and economic costs.
But more discussion is needed than simply comparing deaths due to lockdown v deaths due to COVID-19.
No matter what is mandated, people will adjust their behaviours. Sweden’s economic output shrank by 8.6% in the June quarter, despite its oft-cited light-touch approach. The OECD predicts its economy will contract by 8% in 2020.
The Swedes have self-imposed a lockdown.

Neighbouring Denmark and Norway implemented mandatory lockdowns. Their GDP is forecast to contract by 7% and 8% respectively. Germany also imposed restrictions and its GDP is expected to shrink by a similar amount. The forecast for Australia and New Zealand is 6% and 10% respectively (figure one).
Some of these contractions are due to other countries’ travel restrictions but Sweden’s economy is larger and less reliant on tourism than its neighbours. (In fact, a falling oil price would have inflicted an additional blow on Norway’s national income.)
It seems economic costs appear decoupled from the extent of mandated restrictions.
Is the higher mortality rate worth it?
Sweden’s COVID-19 mortality rate stands at 556 per million, several orders of magnitude greater than comparator countries (figure two).
Germany and Denmark are the closest at 112 and 107, Norway at 49, Australia at 24 (88 in Victoria) and New Zealand at a minuscule 4.5.
Given the economy will contract anyway, are the additional deaths associated with the light-touch approach worth it?
The value of a statistical life in Australia is A$4.9 million (US$3.63 million). Multiplying this by the total deaths in Sweden amounts to 3.9% of GDP — almost half the projected 2020 downturn — again dwarfing the comparator countries’ numbers (figure three).
This suggests the light-touch approach has sacrificed a lot for little economic benefit. Given that 5800 Swedes have died, the strategy would need to prevent an annual economic contraction of 12% — far higher than any of the comparator countries — for the savings to exceed the aggregate value of lives lost.
Of course, because the virus kills mostly older people one could argue that the value of life should be lower because these people have fewer years left. Basing the calculation on how many life years (or even quality-adjusted life years) victims had would produce a more modest number. However, because the mortality demographics are quite similar across countries, the relative differences would remain.
Time will tell who got it right
The true cost of the pandemic and the social policy response will be revealed over time. Herd immunity may prove decisive over the coming months and years and may vindicate the light-touch approach. Although a safe, effective vaccine rolled out in sufficient numbers in 2021 would, depending on the price paid and other costs, most likely justify a stricter strategy.
Sequestering vulnerable parts of the population has also been proposed. It could work but, like all approaches, comes with its own costs and problems.
Imposing a conditional lockdown, for example, would not be easy to implement and manage over time. Letting the virus circulate through most of the population heightens the risk of successive waves, more illness and deaths, and further lockdowns.
Every strategy involves costs and trade-offs. Finding the ideal solution requires a sober analysis of all consequences based on available facts.
At this stage it’s unclear that letting the virus rip is the best, least costly, policy.

I think this statement is wrong “Sweden’s COVID-19 mortality rate stands at 556 per million, several orders of magnitude greater than comparator countries (figure two).”
“Several orders of magnitude” would imply that comparator countries had mortality rates in the realm of 0.01 per million or lower. However, Australia at 24 per million is only one order of magnitude away, and New Zealand at 4.5 is two orders away.
These arguments frequently go off the rails due to fairly basic errors or misunderstandings. Here we have
But if you follow the link in the article to see what a statistical life means you find
The covid virus fatalities are not typically young adults with at least 40 years of life ahead, so this is an absurd way of attributing a value to the total deaths.
Luke does mention this in the article: “Basing the calculation on how many life years (or even quality-adjusted life years) victims had would produce a more modest number…”
… so it’s rather odd he did not use a more modest number.
Did you miss this sentence:
However, because the mortality demographics are quite similar across countries, the relative differences would remain.
I suppose I did, but that would be because Slawomirski has used the absolute financial numbers for comparison with other numbers, not merely to provide a ranking. So he’s trying to have his cake and eat it, and his argument is somewhere between confused and dishonest.
Didn’t miss it, ignored it. Irrelevant.
Yes he mentioned it, but then went ahead using a clearly inaccurate figure to support his opinion.
Attaching a dollar value to a life nearing the end of its natural existence is highly subjective, so limiting the value of this kind of economic analysis. Estimating the lost future earnings of a young person whose current work may no longer is also imprecise. A key question is survival rates of businesses and employment opportunities under differing forms of lock down. As the article reminds us, time will tell. Wicked problems like pandemics only offer the choice of the least wicked solution.
Good article. I would add that the overall cost (incidence / severity / duration) of covid related illnesses affecting younger people has still to be assessed.
I read an article a few weeks ago that indicated that half of people hospitalised were suffering ongoing issues (i.e. damage to blood vessels and organs other than lungs). Has anyone got a link to it? I think it was in The Conversation.
This ABC article references a US CDC study:
https://www.abc.net.au/news/health/2020-07-31/coronavirus-long-and-medium-term-health-effects/12499436
The issue is -because damage to blood vessels probably have the same mechanisms the lung tissues so the smooth lining of the water [blood] pipes are damaged so the pipes to kidneys, brain,and other organs clog up – just like a heart attack – the heart pipes -arteries clog with cholesterol then the blood clots on the roughened pipe stopping flow. Now if that happens in small vessels the organ is stuffed. That is my view in a vernacular nutshell.
I think I read that young people heads were exploding years after catching Covid. The symptoms first show up around the 30th year with pressure on the eardrum, and then two years later, boom.
Given my very life long adapted frugal spending habits, my death would be a boost ,very relatively speaking, to the over all GDP/economy ( the goods n services of dug hole/burning,etc) But i’m such a stingy bastard when it comes to consumerism, that i’m putting my best efforts into staying alive..and consuming less n less of even less..
