Who is to blame for the long, slow, painful journey from the financial crash to global recovery? In this week's column, Martin Wolf argues that the discipline of economics has a lot to learn from its failures both during and after the global financial crisis a decade ago.

The profession was caught unaware and now needs to rebuild, Martin argues. It is not enough to say that the model works in normal times. We need also to understand the risks of crises and what to to do about them.

The basic Keynesian remedies — a strong fiscal and monetary response — remain right. And you can find that view confirmed by contrasting the policies pursued by the US after the crash with those followed in the UK and eurozone. “This recovery really has not been a triumph,” Martin concludes. And furthermore, fundamental macroeconomic theory suggests substantial ignorance of how our economies work, which is far from reassuring.

The suburban doughnut
Sarah O’Connor argues that living costs in thriving cities worldwide are increasingly pushing ordinary, low-paid workers out into a doughnut of affordable housing. From here they commute to jobs in the centre in what has been called the “suburbanisation of poverty”. In the long run, this makes cities unlivable — even for the well-off, who need these workers nearby.

A fix to protect data
Julia Apostle writes that the Facebook data-harvesting affair should unsettle us. The answer to our current lack of control over our personal information online could be “self-sovereign identity,” where individuals control the data elements that form the basis of their digital identities, rather than centralised authorities such as governments and private companies.

What you’ve been saying

Unfortunate effects of Hammond’s criteria — letter from Paul Negrotti

Philip Hammond has made the criteria for loosening the purse strings contingent on the economy’s performance as assessed by the OBR. This unfortunately might have the effect of making fiscal policy pro-cyclical, where if the economy were to perform poorly and have significant slack, policy would not be stimulative, and if it were to perform well with little, policy would be expansionary.

Comment from Kassandra on After Cambridge Analytica, politicians must act to save the web

The internet is a fantastic resource. Social media is not. It was dreamed up by naive American college kids who had no sense that personal information cannot only be used for advertising. It can also be weaponized. Had they bothered to read or shown any interest in totalitarianism, they would have known. But they came of age in the early 2000’s when the march of liberal democracy and globalization seemed unstoppable. Or maybe they just didn’t care about politics. Maybe they were simply oblivious about the world around them.

Evidence does not support ‘conflict of interest’ worries — letter from Jan Bouwens

I understand that the public is cynical about whether lucrative advisory contracts can impair audit quality, and such scepticism can be healthy in professions that have a watchdog role. I also recognise the potential conflict of interest in such arrangements. However, research by leading academics over the past four decades hasn’t found actual evidence of shortcomings that would lend support for sweeping policy changes in this regard. In fact, it is found that, with the provision of advisory services, audit firms extend their knowledge base.
