Vital signs: Government lockdown costs may be exaggerated over COVID-19’s direct economic impact

Confusion abounds over economic cost of the virus compared to cost of lockdowns.

As a second COVID-19 lockdown looms in New South Wales, there is much discussion about the economic costs of doing so.

But since the start of this pandemic there has been profound confusion in many quarters about the economic cost of the virus compared to the economic cost of lockdowns.

It should come as no surprise that having a highly contagious virus with a significant fatality rate running through the community is bad for the economy.

People are afraid to congregate in public or catch public transport or taxis. People don’t want to spend much money when they have debts to pay and their job might be at risk.

This leads to what I have called a “self-lockdown”. No matter what the government mandates, people cut back on economic activity.

Of course, government-coordinated lockdowns entail an extra short-term cost to the economy. Closing pubs and restaurants means those businesses, for a time, have zero revenue.

But how much of the reduction in economic activity is due to the virus, and how much to government lockdowns?

It is crucial to understand this. Because it is the incremental cost of the lockdowns that represents the investment we make in the economy of the future by getting the virus under control. If we think the cost of lockdowns is higher than it really is, we won’t enact them in cases where on balance we should.

Evidence from the United States
The best evidence to date on this matter comes from a remarkable paper circulated in June by University of Chicago economists Austan Goolsbee and Chad Syverson.

To analyse the causal effect of government policy on the US economy during the initial spread of COVID-19, they used mobile phone data to measure foot traffic at 2.25 million individual businesses across 110 industries in the US.

To estimate what proportion of lower foot traffic was due to self-lockdown rather than government-imposed lockdown, they looked at differences between businesses with customer ‘commuting zones’ spanning state or county jurisdictions with different legal restrictions. As they put it:

This leverages two related types of variation: businesses in border-spanning commuting zones where jurisdictions impose shelter-in-place orders at different times (e.g., northern Illinois when Illinois placed a sheltering order on 20 March while Wisconsin waited until the following week), and businesses in commuting zones where a jurisdiction never imposed an order (e.g., the Quad Cities area, where the Illinois towns of Moline and Rock Island faced stay-at-home orders but bordering Davenport and Bettendorf, Iowa, did not).

Goolsbee and Syverson found total consumer traffic fell by 60 percentage points, but legal restrictions accounted for just 7 percentage points of this. That is, it caused less than 12 per cent of the total effect.

Breaking down the data further, they show fear of infection largely drove individual decisions to reduce activity.

In fact, foot traffic “started dropping before the legal orders were in place; was highly influenced by the number of COVID deaths reported in the county; and showed a clear shift by consumers away from busier, more crowded stores toward smaller, less busy stores in the same industry”.

Strikingly, US states that decided to repeal shutdown orders witnessed recoveries of a similar, symmetric size. This is further evidence of the modest incremental impact of lockdowns relative to the larger impact of the virus itself.

Lessons for Australia
We need to stop thinking about lockdowns as representing the total economic hit we take from COVID-19. The virus itself is hugely damaging. Lockdowns add to that, but come with an important benefit – getting the virus under control.

Early in the pandemic, the Australian Treasury estimated Australia’s GDP would fall 10–12 per cent in the June quarter.

Since Treasurer Josh Frydenberg cited this estimate in his National Press Club address on 5 May, many have used it to calculate the cost of a national lockdown at $4 billion a week.

That is, Australia’s GDP is about $2 trillion annually, so a 10 per cent contraction is $200 billion a year, or about $4 billion a week.

But is this really the cost of the lockdown? How much of the estimated 10 per cent drop in GDP for the June quarter is due to the virus and self-lockdown, not government lockdowns?

If the Goolsbee-Syverson numbers translate to Australia, then the lockdown cost is closer to $450 million a week.

That’s still a lot, but a six-week nationwide investment of $2.7 billion to get the virus under control and boost consumer and business confidence was money well spent.

Berejiklian’s dilemma
NSW Premier Gladys Berejiklian has said she doesn’t want to enact a second lockdown because of the hit to economy.

If the current outbreak can be dealt with through rapid contract tracing, testing and isolation, this may be wise.

But if the number of daily cases gets beyond a manageable point, a lockdown might be the only way to stop the spread of the virus.

The best evidence to date shows we cannot have a well-functioning economy with COVID-19 running rampant. That leads to a very costly self-lockdown, regardless of what the government does.The Conversation

    No Not exxagerated. The medium size shopping centre I go to once a fortnight, near empty. about 15% of the shops closed, more now. I spy in the buses that go by. empty now. Where are all the people?. those commuters, would get off the buses and go buy food/drinks. No more. A venue near me which runs a very popular restaurant. Nothing. So no people buying food, no workers, food not being bought for the restaurant. The Chain of buying/spending goes down deep. Not over exagerated at all.

    The small village i live in has been the opposite. The little general store has twice as much produce including fresh veg and fruit, the butcher, baker and yes there is a candlestick/pottery shop are seeing a big increase in trade.

    The chemist is doing well and there are several cafes and restaurants all doing more trade in take away. There is a post office and a BWS.

    We may have abandoned the centres but the villages are coming back.

    Prices are a bit higher but somehow it feels safer.

    What is the true cost of covid-19? What are the true costs of the responses? I refer to a Blog posted in the London Review of Books on the 20th of July 2020 by Ms Sophie Cousins. Ms Cousins reports on research undertaken by McGill University. I am reproducing the results of the research here. Doubting Thomas's can read the article for themselves. McGill University's results are that there will be 400,000 additional deaths from malaria this year alone; 700,000 additional deaths from HIV in Africa alone; 15 million additional pregnancies; up to 1.4 million extra deaths from TB by 2025; 80 million children under age one at risk of vaccine preventable diseases such as measles, rubella and polio as a result of disruptions to immunization services in almost 70 countries; 113,000 additional maternal deaths in the next 12 months due to disruptions to pre-natal, during pregnancy, and post-natal care; and that global poverty, a major driver of poor health, is set worsen. When the economic devastation is added to that list, how does a decent, intelligent and humane person weigh the costs of covid-19 against the costs of the responses? What should our responses really be when the global effects are gathered in?

    In my post on the costs of covid-19 I incorrectly dated the blog in the LRB I refer to as the 20th of July; the correct date is 9th of July. My apologies.

    Well, let us hope that it is overestimated, and not treat that as being a bad thing
