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.

Want to send a positive Brexit message to Europe? Back Arsene Wenger for England manager

Boris Johnson could make a gesture of goodwill. 

It is hard not to feel some sympathy for Sam Allardyce, who coveted the England job for so many years, before losing it after playing just a single match. Yet Allardyce has only himself to blame and the Football Association were right to move quickly to end his tenure.

There are many candidates for the job. The experience of Alan Pardew and the potential of Eddie Howe make them strong contenders. The FA's reported interest in Ralf Rangner sent most of us scurrying to Google to find out who the little known Leipzig manager is. But the standout contender is Arsenal's French boss Arsene Wenger, 

Would England fans accept a foreign manager? The experience of Sven Goran-Eriksson suggests so, especially when the results are good. Nobody complained about having a Swede in charge the night that England won 5-1 in Munich, though Sven's sides never won the glittering prizes, the Swede proving perhaps too rigidly English in his commitment to the 4-4-2 formation.

Fabio Capello's brief stint was less successful. He never seemed happy in the English game, preferring to give interviews in Italian. That perhaps contributed to his abrupt departure, falling out with his FA bosses after he seemed unable to understand why allegations of racial abuse by the England captain had to be taken seriously by the governing body.

Arsene Wenger could not be more different. Almost unknown when he arrived to "Arsene Who?" headlines two decades ago, he became as much part of North London folklore as all-time great Arsenal and Spurs bosses, Herbert Chapman or Bill Nicholson, his own Invicibles once dominating the premier league without losing a game all season. There has been more frustration since the move from Highbury to the Emirates, but Wenger's track record means he ranks among the greatest managers of the last hundred years - and he could surely do a job for England.

Arsene is a European Anglophile. While the media debate whether or not the FA Cup has lost its place in our hearts, Wenger has no doubt that its magic still matters, which may be why his Arsenal sides have kept on winning it so often. Wenger manages a multinational team but England's football traditions have certainly got under his skin. The Arsenal boss has changed his mind about emulating the continental innovation of a winter break. "I would cry if you changed that", he has said, citing his love of Boxing Day football as part of the popular tradition of English football.

Obviously, the FA must make this decision on football grounds. It is an important one to get right. Fifty years of hurt still haven't stopped us dreaming, but losing to Iceland this summer while watching Wales march to the semi-finals certainly tested any lingering optimism. Wenger was as gutted as anybody. "This is my second country. I was absolutely on my knees when we lost to Iceland. I couldn't believe it" he said.

The man to turn things around must clearly be chosen on merit. But I wonder if our new Foreign Secretary Boris Johnson - albeit more of a rugger man himself - might be tempted to quietly  suggest in the corridors of footballing power that the appointment could play an unlikely role in helping to get the mood music in place which would help to secure the best Brexit deal for Britain, and for Europe too.

Johnson does have one serious bit of unfinished business from the referendum campaign: to persuade his new boss Theresa May that the commitments made to European nationals in Britain must be honoured in full.  The government should speed up its response and put that guarantee in place. 

Nor should that commitment to 3m of our neighbours and friends be made grudgingly.

So Boris should also come out and back Arsene for the England job, as a very good symbolic way to show that we will continue to celebrate the Europeans here who contribute so much to our society.

British negotiators will be watching the twists and turns of the battle for the Elysee Palace, to see whether Alain Juppe, Nicolas Sarkozy end up as President. It is a reminder that other countries face domestic pressures over the negotiations to come too. So the political negotiations will be tough - but we should make sure our social and cultural relations with Europe remain warm.

More than half of Britons voted to leave the political structures of the European Union in June. Most voters on both sides of the referendum had little love of the Brussels institutions, or indeed any understanding of what they do.

But how can we ensure that our European neighbours and friends understand and hear that this was no rejection of them - and that so many of the ways that we engage with our fellow Europeans rom family ties to foreign holidays, the European contributions to making our society that bit better - the baguettes and cappuccinos, cultural links and sporting heroes remain as much loved as ever.

We will see that this weekend when nobody in the golf clubs will be asking who voted Remain and who voted Leave as we cheer on our European team - seven Brits playing in the twelve-strong side, alongside their Spanish, Belgian, German, Irish and Swedish team-mates.

And now another important opportunity to get that message across suddenly presents itself.

Wenger for England. What better post-Brexit commitment to a new Entente Cordiale could we possibly make?
