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.

The footie is back. Three weeks in and what have we learned so far?

Barcleys, boots and big names... the Prem is back.

Another season, another reason for making whoopee cushions and giving them to Spurs fans to cheer them up during the long winter afternoons ahead. What have we learned so far?

Big names are vital. Just ask the manager of the Man United shop. The arrival of Schneiderlin and Schweinsteiger has done wonders for the sale of repro tops and they’ve run out of letters. Benedict Cumberbatch, please join Carlisle United. They’re desperate for some extra income.

Beards are still in. The whole Prem is bristling with them, the skinniest, weediest player convinced he’s Andrea Pirlo. Even my young friend and neighbour Ed Miliband has grown a beard, according to his holiday snaps. Sign him.

Boots Not always had my best specs on, but here and abroad I detect a new form of bootee creeping in – slightly higher on the ankle, not heavy-plated as in the old days but very light, probably made from the bums of newborn babies.

Barclays Still driving me mad. Now it’s screaming from the perimeter boards that it’s “Championing the true Spirit of the Game”. What the hell does that mean? Thank God this is its last season as proud sponsor of the Prem.

Pitches Some groundsmen have clearly been on the weeds. How else can you explain the Stoke pitch suddenly having concentric circles, while Southampton and Portsmouth have acquired tartan stripes? Go easy on the mowers, chaps. Footballers find it hard enough to pass in straight lines.

Strips Have you seen the Everton third kit top? Like a cheap market-stall T-shirt, but the colour, my dears, the colour is gorgeous – it’s Thames green. Yes, the very same we painted our front door back in the Seventies. The whole street copied, then le toot middle classes everywhere.

Scott Spedding Which international team do you think he plays for? I switched on the telly to find it was rugby, heard his name and thought, goodo, must be Scotland, come on, Scotland. Turned out to be the England-France game. Hmm, must be a member of that famous Cumbrian family, the Speddings from Mirehouse, where Tennyson imagined King Arthur’s Excalibur coming out the lake. Blow me, Scott Spedding turns out to be a Frenchman. Though he only acquired French citizenship last year, having been born and bred in South Africa. What’s in a name, eh?

Footballers are just so last season. Wayne Rooney and Harry Kane can’t score. The really good ones won’t come here – all we get is the crocks, the elderly, the bench-warmers, yet still we look to them to be our saviour. Oh my God, let’s hope we sign Falcao, he’s a genius, will make all the difference, so prayed all the Man United fans. Hold on: Chelsea fans. I’ve forgotten now where he went. They seek him here, they seek him there, is he alive or on the stairs, who feckin’ cares?

John Stones of Everton – brilliant season so far, now he is a genius, the solution to all of Chelsea’s problems, the heir to John Terry, captain of England for decades. Once he gets out of short trousers and learns to tie his own laces . . .

Managers are the real interest. So refreshing to have three young British managers in the Prem – Alex Neil at Norwich (34), Eddie Howe at Bournemouth (37) and that old hand at Swansea, Garry Monk, (36). Young Master Howe looks like a ball boy. Or a tea boy.

Mourinho is, of course, the main attraction. He has given us the best start to any of his seasons on this planet. Can you ever take your eyes off him? That handsome hooded look, that sarcastic sneer, the imperious hand in the air – and in his hair – all those languages, he’s so clearly brilliant, and yet, like many clever people, often lacking in common sense. How could he come down so heavily on Eva Carneiro, his Chelsea doctor? Just because you’re losing? Yes, José has been the best fun so far – plus Chelsea’s poor start. God, please don’t let him fall out with Abramovich. José, we need you.
