Virus modellers must admit their mistakes and learn from the practice of transparency

By now, we all know about the poor track record of prediction by the academic modelling teams advising the Scientific Advisory Group for Emergencies – Sage. The unreliable nature of economic projections is also evident, as analysis of  the Survey of Professional Forecasters (SPF) database shows. Yet the epidemiologists could still  learn from the experience […]

Want people to get the Covid vaccine? Pay them

The vaccines seem to be coming thick and fast. The task now is to ensure that enough people get them to keep the virus under control. The first issue is one of logistics. The track record of the UK’s health bureaucracy during the crisis has not been good. But the NHS does have experience of […]

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

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 […]
