It is science, not lockdowns, that will save the world
The various new vaccines announced over the past two weeks give real hope of a return to normal life. Of course, many practical questions remain. How will these vaccines be delivered? Do they stop the transmission or simply the symptoms of the virus? Exactly how effective will they be outside a controlled trial environment? But […]
The public are not to blame for the second lockdown
Justice secretary Robert Buckland last week blamed the public for England’s new lockdown. In particular, the fault was with people failing to self-isolate properly. Of course, in a purely technical sense Buckland is right. The virus spreads by contact with an infected person. If people do not self-isolate, Covid-19 will continue to percolate across the […]
Lockdown 2.0: A creative destruction revolution, or the death knell of innovation?
So Boris Johnson has failed to follow his own government’s guidelines on cost-benefit appraisal. Study after study by economists show that the costs of lockdown far exceed the benefits. The NHS — the “envy of the world” — has conspicuously failed to develop sufficient capacity to deal with a second wave, despite having had months […]
Forget the polls endorsing lockdowns and look at how people actually behave
Economics is at long last storming the bastions of the Scientific Advisory Group for Emergencies (SAGE). This citadel of epidemiologists and health professionals has for many months resisted the lessons which the so-called gloomy science can bring. In the context of Covid-19, economics is in fact a beacon of hope. This week, news broke of […]
The government must take back control of the Covid narrative
The word “narrative” is usually seen as being a posh way of saying “story”. But the idea of narratives is one which is gaining traction in economics. Last year, for example, Nobel laureate Robert Shiller of Yale published a book entitled “Narrative Economics”. He argued that it is the perception of events and the stories […]
Heavy-handed Westminster diktats have eroded trust — now only localised Covid policy can restore it
Last month, the official group of scientific advisers — SAGE — warned the government that only a quarter of those who need to self-isolate due to coronavirus symptoms were in fact doing so. This illustrates a concept which is of great practical importance: namely the conflict between individual and collective rationality. Consider Margaret Ferrier, an […]
Following the science? This government lacks a basic grasp of the scientific method
Verification and validation. It is hard to imagine a more nerdy phrase. But it is, in essence, how science makes progress. It is what we have to do to check whether a scientific claim or theory is correct. And it has been seriously neglected during the Covid-19 crisis. Just over a century ago, for example, […]
And this week’s winner for the Stupid Scientist award is…
Scepticism about the advice given by government scientists about Covid-19 is rising sharply. In areas like Bolton infections are high. Interviews with the locals reveal that so, too, is disbelief in the veracity of the statements made by members of SAGE, the government science advisory group. The scientists, rational beings themselves, may ascribe this to […]
Incentives are a better way to tackle Covid-19 than blanket lockdowns
A great deal of government policy during the Covid crisis has involved regulation. Given a choice, economists usually prefer to use incentives. Altering the relative costs and benefits of an action is a well-established way to alter behaviour. Perhaps the government has been listening. A big stick will now be waved at people who fail […]
Coronavirus fatality rates are way down – why has the government not taken this on board?
King Canute has had a bad press. The monarch sat on the beach on his throne with the deliberate intention of demonstrating to his courtiers that he could not stop the waves from coming in. But in popular thinking, he is the deranged king who believed he could control the sea. In this spirit, step […]
On coronavirus, governments have been the most irrational of us all
Decisions, whether by individuals, companies or governments, are often made with imperfect and incomplete information. This is so obvious as to hardly seem worth stating. But for well over a century economic theory assumed that decisions were made with complete information. Economists knew full well that this was not always the case. The problem was […]
Sweden shows us whether lockdown was worth the economic cost
Did Sweden get it right in its response to Covid? There is increasing interest in this question. Contrary to widespread belief, the Swedes did introduce a few legally enforceable restrictions on behaviour. For example, public gatherings of more than 50 people were forbidden in March. Private ones were exempt from the ban. But, overall, compared […]
Busting the myth of the selfless bureaucrat
There seems to be a fundamental problem with quangos. Hardly a day seems to go by without some new story of incompetence and mismanagement emerging. Public Health England (PHE) is at least going to be put out of its misery by health secretary Matt Hancock, and replaced with a new agency specifically focused on pandemics. […]
The costs of lockdown can no longer be justified
In an otherwise depressing week, two pieces of very good news emerged from India. In Mumbai, blood tests conducted by the city authorities on 6,936 randomly selected people found that some 40 per cent had coronavirus antibodies. Just 6,000 deaths have been reported so far in a city of 20 million. A similar exercise in […]
Great expectations: The Darwinian wars of economic and epidemiological forecasting
A key concept in modern economics is, to use the jargon term, rational expectations. The idea has dominated orthodox macroeconomics over the past 30 years. Not all economists have been persuaded of its merits by any means, but nevertheless, its influence has extended far beyond academia, into finance ministries and central banks around the world. […]
