Must-Read: Simon Wren-Lewis: Attacking Economics is a Diversionary Tactic: "The financial crisis in the UK was the result of losses by banks on overseas assets, originating from the collapse in the US subprime market...
...UK macroeconomists failed to pick up the impending crisis [because] they did [not] routinely monitor... bank leverage. Macroeconomists generally acknowledge that they were at fault in ignoring the crucial role that financial sector leverage can play.... Admati and Hellweg have written persuasively that we need a huge increase in bank capital requirements to bring the ‘too big to fail’ problem to an end and avoid a future banking crisis, and the work of David Miles in the UK has a similar message.

In terms of conventional monetary and fiscal policy, academic economists got the response to the crisis right, and policymakers got it very wrong....

This is not a new phenomenon, as I showed in connection with the famous letter from 364 economists.... The media did the rest of the job for them by hardly ever talking about the majority of economists who did not support austerity....
