Yielding to temptation

An introduction to behavioural economics.

One human weakness that we are all familiar with is that we are forever making plans for the future that involve some kind of self-improvement, but later on we renege on these plans and yield to temptation, taking an "easy way out". For example, we plan on going for a run this evening, but then decide to lay back on the couch and watch TV instead; we may go to bed planning to rise at 6am, but when the alarm rings we rapidly hit the snooze button and end up oversleeping. On a more long-term basis, we plan to make regular savings for retirement, but then decide we should spend our money on new furniture for the living room, a new set of golf clubs, and so it goes on. In general we make plans to achieve a larger benefit later, but then change our minds and settle for a smaller benefit sooner.

For a long time, economists have abstracted from such complexities of human decision making. The standard model of economic rationality suggests that we should only change our minds if and when appropriate new information is received. But often the change of mind is not caused by new information. Why humans tend to behave in this way is still a subject of controversy. However, rather than continuing to regard them as an anomaly, economists have begun treating these variations in our behaviour more seriously. Under the label of behavioural economics, new approaches to the study of decision making have been emerging which are catching the imagination of politicians.

Saving for retirement for example is a serious problem for many. Much evidence from the UK and US suggests that a large proportion of people do not save sufficiently for retirement. Various measures that have become known as ‘nudge’ policies are being suggested to address this as an issue of public policy. Unlike traditional regulation by government, nudge policies do not seek to compel us to behave in certain ways, but change what is called the ‘choice architecture’ of the situation, providing incentives for us to act in certain ways. A common nudge policy is to change the default option in a choice situation. Thus, if employers’ pension plans require employees to opt in, there will be a tendency for many to go with the default of remaining outside the scheme. Evidence from the US suggests that the simple measure of reversing this option can substantially increase the number of employees contributing to retirement plans. Furthermore, options can be framed in a way to encourage greater contributions than employees might otherwise make. For example, if people are given 3 options in terms of size of contribution, say £100, £120, and £140 per month, many will choose the middle option. Simply changing the options to £160, £180, and £200 per month automatically increases people’s willingness to contribute, as once again people tend to go for the middle option.

The UK government has taken some of these findings of behavioural economists on board. The 2011 Pensions Act has established default enrollment options which will be implemented in the UK economy over the next six years. A Behavioural Insights Team attached to the Cabinet Office is exploring further applications of nudge policies in other areas such as eating habits or organ donation. However, their effectiveness remains controversial. Many doctors doubt that nudge policies are sufficient to encourage people to change their dietary or smoking habits, and believe that more radical intervention is necessary. Wider debates have focused on the merit and scope of the underlying 'benevolent paternalism' and its implied call for the large scale engineering of choice architectures across the economy. But this does not detract from the fact that the behavioural turn in economics is proving to have a lasting impact on public policy and is rapidly reshaping the economics curriculum taught at universities today.

John McDonnell interview: "We’re going to destroy Osborne’s credibility"

The shadow chancellor on the Spending Review, Jeremy Corbyn's leadership and why trade unions will have to break the law. 

When I interviewed John McDonnell in March, before the general election, he predicted that Labour would be the largest party and confessed to a “sneaking feeling that we could win a small majority – because I think the Tory vote is really soft”. As the long-standing chair of the Socialist Campaign Group, McDonnell anticipated leading the resistance inside Labour to any spending cuts made by Ed Miliband. Eight months later, he is indeed campaigning against austerity – but as shadow chancellor against a Conservative majority government.

I meet McDonnell in his new Westminster office in Norman Shaw South, a short walk down the corridor from that of his close friend and greatest ally, Jeremy Corbyn. The day before George Osborne delivers his Spending Review and Autumn Statement, his desk is cluttered with economic papers in preparation for his response.

“The message we’re trying to get across is that this concept of the Tories’ having a ‘long-term economic plan’ is an absolute myth and they’re in chaos, really in chaos on many fronts,” he tells me. McDonnell points to the revolt against cuts to tax credits and policing, and the social care crisis, as evidence that Osborne’s programme is unravelling. On health, he says: “He’s trying to dig out money as best as he can for the NHS, he’s announced the frontloading of some of it, but that simply covers the deficits that there are. Behind that, he’s looking for £22bn of savings, so this winter the NHS is going to be in crisis again.”

Asked what Labour’s equivalent is to the Tories’ undeniably effective “long-term economic plan” message, he said: “I don’t think we’re going to get into one-liners in that way. We’ll be more sophisticated in the way that we communicate. We’re going to have an intelligent and a mature economic debate. If I hear again that they’re going to ‘fix the roof while the sun shines’ I will throw up. It’s nauseating, isn’t it? It reduces debate, intellectual debate, economic debate, to the lowest level of a slogan. That’s why we’re in the mess we are.”

Having abandoned his original support for the Chancellor’s fiscal charter, which mandated a budget surplus by 2020, McDonnell makes an unashamed case for borrowing to invest. “The biggest failure of the last five years under Osborne is the failure to invest,” he says. “Borrowing at the moment is at its cheapest level, but in addition to that I’m not even sure we’ll need to borrow great amounts, because we can get more efficient spending in terms of government spending. If we can address the tax cuts that have gone ahead, particularly around corporation tax, that will give us the resources to actually start paying again in terms of investment.”

He promises a “line-by-line budget review” when I ask whether there are any areas in which he believes spending should be reduced. “My background is hard-nosed bureaucrat . . . we’ll be looking at where we can shift expenditure into more productive areas.”

From 1982 until 1985, John McDonnell, who is 64, was chair of finance at the Greater London Council under Ken Livingstone. After vowing to defy the Thatcher government’s rate-capping policy he was sacked by Livingstone, who accused him of manipulating figures for political purposes. “We’re going to look like the biggest fucking liars since Goebbels,” the future mayor of London told him. McDonnell, who later described Livingstone’s account as “complete fiction”, has since resolved his differences with the man now co-chairing Labour’s defence review.

After his election as the MP for Hayes and Harlington in 1997, McDonnell achieved renown as one of New Labour’s most vociferous opponents, rebelling with a frequency rivalled only by Corbyn. His appointment as shadow chancellor was the most divisive of the Labour leader’s reshuffle. “People like Jeremy even if they don’t agree with him. People don’t like John,” one MP told me at the time. Mindful of this, McDonnell has sought to transform his image. He has apologised for his past praise of the IRA and for joking about assassinating Margaret Thatcher, rebranding himself as a “boring bank manager”. But there are moments when his more radical side surfaces.

He told me that he supports workers breaking the law if the trade union bill, which would limit the right to strike, is passed. “It’s inevitable, I think it’s inevitable. If the bill is introduced in its existing form and is used against any particular trade unionist or trade union, I think it’s inevitable that people will resist. We established our rights by campaigning against unjust laws and taking the risk if necessary. I think that’s inevitable and I’ll support them.”

“Chaos” might be how McDonnell describes Osborne’s position but the same term is now daily applied to Labour. The party is riven over air strikes in Syria and the renewal of Trident and MPs are ever more scornful of Corbyn’s leadership.

While Corbyn has so far refused to offer Labour MPs a free vote on Syria, McDonnell says that he favours one and would oppose military action. “My position on wars has always been that it’s a moral issue and therefore I veer towards free votes . . . We’re waiting for Cameron’s statement; we’ll analyse that, there’ll be a discussion in shadow cabinet and in the PLP [Parliamentary Labour Party] and then we’ll make a decision. I’m still in a situation where I’ve expressed the view that I’m opposed to the bombing campaign or engagement. I think the history of the UK involvement in the Middle East has been a disaster, to say the least . . .This isn’t like the Second World War where you have a military campaign – you defeat the enemy, you sign a peace agreement and that’s it – this is asymmetric warfare. In addition to the risks that are in the battlefield there’s a risk in every community in our land as a result of it.”

Would he want any of the 14 former shadow cabinet members who refused to serve under Corbyn to return? “All of them, we’re trying to get them all back. We’ve got Yvette [Cooper] helping us on a review we’re doing about the economy and women . . . It’s an open door policy, I’m trying to meet them all over these next few weeks.”

Livingstone, a member of Labour’s National Executive Committee, recently called for Simon Danczuk, who revealed details of a private meeting with Corbyn in the Mail on Sunday, and Frank Field, who told me that MPs should run as independents if deselected, to be disciplined. But McDonnell takes a more conciliatory line. “With Simon [Danczuk] in particular and the others, it’s just a matter of saying look at the long-term interests of the party. People don’t vote for a divided party. They’ll accept, though, that within a party you can have democratic debate. As I said time and time again, don’t mistake democracy for division. It’s the way in which you express those different views that are important. All I’m saying is let people express their views, let’s have democratic engagement but please don’t personalise this. I think there’s a reaction within the community, not just the party, against personalised politics. It’s not Jeremy’s style, he never responds in that way. It’s unfortunate but we’ll get through it. It’s just minor elements of it, that’s all.”

McDonnell disavows moves by some in Momentum, the Corbyn-aligned group, to deselect critical MPs. “What we’re not into is deselecting people, what we want to try and do is make sure that everyone’s involved in a democratic engagement process, simple as that.

“So I’ve said time and time again, this isn’t about deselection or whatever. But at the same what we’re trying to say to everybody is even if you disagree, treat each other with respect. At the height of the debates around tuition fees and the Iraq war, even though we had heated disagreements we always treated each other with mutual respect and I think we’ve got to adhere to that. Anyone who’s not doing that just lets themselves down, that’s not the culture of the Labour Party.”

In private, the 90 per cent of MPs who did not support Corbyn’s leadership bid speak often of how and when he could be removed. One point of debate is whether, under the current rules, the Labour leader would automatically make the ballot if challenged or be forced to re-seek nominations. McDonnell is emphatic that the former is the case: “Oh yeah, that’s the rule, yeah.”

McDonnell’s recent media performances have been praised by MPs, and he is spoken of by some on the left as a possible replacement if Corbyn is removed or stands down before 2020. His speech to the PLP on 23 November was described to me by one shadow minister as a “leadership bid”. But McDonnell rules out standing in any future contest. “No, no, I’ve tried twice [in 2007 and 2010], I’m not going to try again, there’s no way I would.”

Despite opinion polls showing Labour as much as 15 points behind the Conservatives, McDonnell insists that the party can win in 2020. “Oh definitely, yeah, you’ll see that. I think this next year’s going to be pivotal for us. We’re going to destroy Osborne’s credibility over the next six months. But more importantly than that, we can’t just be a negative party . . . we’re going to present a positive view of what Labour’s future will be and the future of the economy.

“Over the next 18 months, we’ll be in a situation where we’ve destroyed the Tories’ economic reputation and we’ve built up our own but we’ll do it in a visionary way that presents people with a real alternative.”
