The economists who support the use of social distancing measures to slow the spread of COVID-19 are not only in the majority, they are also more certain of their opinions than those who do not.
A realistic estimate of the economic costs of a two-year lockdown amounts to $90 billion. The benefit in lives saved amounts to at $1.1 trillion.
The lock-downs are saving more lives than they cost, but eventually the costs will rise to the point where they exceed the value of lives saved.

We’ve prevented many deaths, many of them at the cost of other deaths. The accounting ought to be made clear.
When we unlock, we should do it cautiously, starting with small social gatherings, and we should test widely.
It is possible to calculate the impact impact of fires, but not using GDP.
GDP is well suited to many things, but not to measuring the impact of disasters.

We are getting closer to being able to apply private sector rigour to the examination of public sector projects with social benefits.

Prisons are big business in Australia. Companies not only run entire prisons but provide many of the services. But what does the research say about the impact?
Which links are most important in road and information networks?
When planning major infrastructure investments, it’s important to know which road, freight and information networks are most important – and which proposals might make things worse, not better.
A new Grattan Institute report suggests solar panels in Australia might be more trouble than they are worth.
The Grattan Institute has reported that the costs of solar panels have outweighed the benefits by almost A$10 billion in Australia. But the real benefits of cutting greenhouse emissions are much larger.
The NBN cost-benefit analysis plays down many potential benefits.
When the Rudd government announced the construction of the National Broadband Network in 2009 with an estimated cost of A$36 billion (and public sector contribution of $28 billion), it did so based on…
Tony Abbott has the support of business leaders, but will it last?
In his victory speech on election night last September, prime minister Tony Abbott declared Australia was “under new management and … once more open for business”. There were, of course, specific promises…
The NBN was not subjected to a cost benefit analysis - but this may not have circumvented controversy around the merits of the project.
Big infrastructure projects, such as the National Broadband Network, cost big money. So, how do we use public money wisely? For communications minister Malcolm Turnbull and the Coalition government, a…
