And gets it wrong of course:
In April, UK GDP was 25% below its level in February. While such a rapid fall in output is unprecedented, so are the reasons for it. Unfortunately many Conservative MPs seem to think the collapse in output is due to the lockdown, whereas in reality it is due to the pandemic. If there had been no lockdown, and the epidemic had run its course unhindered, we would have seen a fall in output of similar size.
No, there are two effects going on. One is the simple and individual reaction to a pandemic, the other is the effect of the lockdown. The effect of the lockdown possibly being additional to that individual change in behaviour and at least in theory it could be a negative, reducing that effect.
To claim that lockdown had no additional effect at all is to insist that Sweden will have exactly the same GDP fall as Norway and Denmark – two broadly similar economies with different lockdown policies. That is, we can test this proposition – anyone feeling confident enough to join Simon Wren-Lewis in his claim?
