Time to complicate things

If we stop trying to simplify our economic models, we can improve policy.

According to the increasingly influential school of complexity economics, decisions that at the "micro" level might seem rational, when they become manifest at the "macro" level produce outcomes that are detrimental to all. Several "rights" often combine to produce a "wrong". This can help to explain problems like why there is such an unequal distribution of wealth in many developed economies and why some regions remain depressed for long periods of time.

Neo-classical economics finds it difficult to account for such emergent problems because it is based on a framework of simple, bilateral exchanges between individuals (people and firms). It is forced to regard economy-wide problems as the result of some external disruption to the normal running of free bilateral exchange. As a result, it has failed to develop an adequate theory that makes a connection between individual decisions and developments in the aggregate economy.  

The new fields of complexity theory and network theory help us to understand the economy as a dynamic network, rather than as the static model of bilateral exchange, which underlies orthodox economics. With this new understanding, we can start to develop policy options that might respond more effectively to problems like inequality of wealth.  

Although the school of complexity economics and the idea of emergent phenomena are relatively new, the recognition of system-wide economic problems is clearly not. But, for a long time, most economic thinking has held that many of our fundamental challenges, such as inequality and climate issues, are the result of market failures and can only be solved by using the power of the state to correct any such failures.  

A complexity perspective suggests the state’s top-down bureaucracy cannot, as it currently operates, offer effective and sustainable solutions to emergent economic problems. The state's policy-making incorporates the idea that society acts like a machine that responds automatically to a stimulus (such as a tax cut) in the same way each time, in large part because mainstream economics has taken a very narrow view of human nature and interaction. This has been explored most recently by Paul Ormerod in his book, Positive Linking.

Complexity theory is based on the core observation that social systems are dynamic, evolving networks in which individual and collective behaviour can shift and change rapidly and unexpectedly. The fluidity of this system means attempts to control an economy by gathering data, making forecasts and developing policy will always be subject to a high risk of failure. Mechanistic approaches to policy can be extremely problematic, for at least four broad reasons:  

  1. Idiosyncrasies matter and it is a near impossibility for a centrally determined policy to remain sensitive to local circumstances.
  2. Remotely set targets can be inaccurate proxies for real aims.
  3. Network effects can drown out the very incentives that form the core of most policy responses.
  4. Incentives are often set as if people were selfish maximisers of their own utility - but this is very often untrue.  

The neoclassical approach is comforting in the sense it implies that following simple, easy to devise, mechanical policy rules can solve some problems. But it is misleading because the economy does not work in the way it suggests, which often leads to inappropriate policy ideas. With the complexity approach things are, roughly speaking, the other way around. It suggests policy responses to certain problems will be hard to draw up, and the right answer might be found only after experimentation, simulation, and pilot studies. But the policy formed as a result is more likely to be suited to the policy challenge.  

The new fields of complexity and network theory advocate building up an understanding of the real world from the ground up. In doing so, they paint a picture of the real world that is much more recognisable than the abstractions of neoclassical economics. As such, they have the potential to offer new approaches to seemingly intractable policy problems, and, because these approaches are inherently apolitical, they ought to be of interest to all political parties.

Labour is launching a stealthy Scottish comeback - thanks to Jeremy Corbyn and the Daily Mail

The Scottish Labour strategy is paying off - and hard evidence that it works may be more plentiful come 8 June 2017

When I suggested to a senior Scottish Labour figure earlier this year that the party was a car crash, he rejected my assertion.

“We’re past that,” he said gloomily. “Now we’re the burnt-out wreck in a field that no-one even notices anymore.”

And yet, just as the election campaign has seen Jeremy Corbyn transformed from an outdated jalopy into Chitty Chitty Bang Bang magically soaring in the polls, Scottish Labour is beginning to look roadworthy again.

And it’s all down to two apparently contradictory forces – Corbyn and The Daily Mail.

Kezia Dugdale’s decision to hire Alan Roden, then the Scottish Daily Mail’s political editor, as her spin doctor in chief last summer was said to have lost her some party members. It may win her some new members of parliament just nine months later.

Roden’s undoubted nose for a story and nous in driving the news agenda, learned in his years at the Mail, has seen Nicola Sturgeon repeatedly forced to defend her government record on health and education in recent weeks, even though her Holyrood administration is not up for election next month.

On ITV’s leaders debate she confessed that, despite 10 years in power, the Scottish education system is in need of some attention. And a few days later she was taken to task during a BBC debate involving the Scottish leaders by a nurse who told her she had to visit a food bank to get by. The subsequent SNP attempt to smear that nurse was a pathetic mis-step by the party that suggested their media operation had gone awry.

It’s not the Tories putting Sturgeon on the defence. They, like the SNP, are happy to contend the general election on constitutional issues in the hope of corralling the unionist vote or even just the votes of those that don’t yet want a second independence referendum. It is Labour who are spotting the opportunities and maximising them.

However, that would not be enough alone. For although folk like Dugdale as a person – as evidenced in Lord Ashcroft’s latest polling - she lacks the policy chops to build on that. Witness her dopey proposal ahead of the last Holyrood election to raise income tax.

Dugdale may be a self-confessed Blairite but what’s powering Scottish Labour just now is Jeremy Corbyn’s more left-wing policy platform.

For as Brexit has dropped down the agenda at this election, and bread and butter stuff like health and education has moved centre stage, Scots are seeing that for all the SNP’s left wing rhetoric, after 10 years in power in Holyrood, there’s not a lot of progressive policy to show for it.

Corbyn’s manifesto, even though huge chunks of it won’t apply in Scotland, is progressive. The evidence is anecdotal at the moment, but it seems some Scots voters find it more attractive than the timid managerialism of the SNP. This is particularly the case with another independence referendum looking very unlikely before the 2020s, on either the nationalists' or the Conservatives' timetable.

Evidence that the Scottish Labour strategy has worked may be more plentiful come 8 June 2017. The polls, albeit with small sample sizes so best approached with caution, have Ian Murray streets ahead in the battle to defend Edinburgh South. There’s a lot of optimism in East Lothian where Labour won the council earlier in May and MSP Iain Gray increased his majority at the Scottish election last year. Labour have chosen their local candidate well in local teacher Martin Whitfield, and if the unionist vote swings behind him he could overhaul sitting MP George Kerevan’s 7,000 majority. (As we learned in 2015, apparently safe majorities mean nothing in the face of larger electoral forces). In East Renfrewshire, Labour's Blair McDougall, the man who led Better Together in 2014, can out-unionist the Tory candidate.

But, while in April, it was suggested that these three seats would be the sole focus of the Scottish Labour campaign, that attitude has changed after the local elections. Labour lost Glasgow but did not implode. In chunks of their former west of Scotland heartlands there was signs of life.

Mhairi Black’s a media darling, but her reputation as a local MP rather than a local celebrity is not great. Labour would love to unseat her, in what would be a huge upset, or perhaps more realistically go after Gavin Newlands in the neighbouring Paisley seat.

They are also sniffing Glasgow East. With Natalie McGarry’s stint as MP ending in tears – a police investigation, voting in her wedding dress and fainting in the chamber sums up her two years in Westminster – Labour ought to be in with a chance in the deprived neighbourhoods of Glasgow’s east end.

Labour in Scotland doesn’t feel like such a wreck anymore. Alan Roden’s Daily Mail-honed media nous has grabbed attention. Corbyn’s progressive policies have put fuel in the tank.

After polling day, the party will be able to fit all its Scottish MPs comfortably in a small hatchback, compared to the double decker bus necessary just a few years back.

But this general election could give the party the necessary shove to get on to the long road back.
