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 SNP thinks it knows how to kill hard Brexit

The Supreme Court ruled MPs must have a say in triggering Article 50. But the opposition must unite to succeed. 

For a few minutes on Tuesday morning, the crowd in the Supreme Court listened as the verdict was read out. Parliament must have the right to authorise the triggering of Article 50. The devolved nations would not get a veto. 

There was a moment of silence. And then the opponents of hard Brexit hit the phones. 

For the Scottish government, the pro-Remain members of the Welsh Assembly and Sinn Féin in Northern Ireland, the victory was bittersweet. 

The ruling prompted Scotland’s First Minister, Nicola Sturgeon, to ask: “Is it better that we take our future into our own hands?”

Ever the pragmatist, though, Sturgeon has simultaneously released her Westminster attack dogs. 

Within minutes of the ruling, the SNP had vowed to put forward 50 amendments (see what they did there) to UK government legislation before Article 50 is enacted. 

This includes the demand for a Brexit white paper – shared by MPs from all parties – to a clause designed to prevent the UK reverting to World Trade Organisation rules if a deal is not agreed. 

But with Labour planning to approve the triggering of Article 50, can the SNP cause havoc with the government’s plans, or will it simply be a chorus of disapproval in the rest of Parliament’s ear?

The SNP can expect some support. Individual SNP MPs have already successfully worked with Labour MPs on issues such as benefit cuts. Pro-Remain Labour backbenchers opposed to Article 50 will not rule out “holding hands with the devil to cross the bridge”, as one insider put it. The sole Green MP, Caroline Lucas, will consider backing SNP amendments she agrees with as well as tabling her own. 

But meanwhile, other opposition parties are seeking their own amendments. Jeremy Corbyn said Labour will seek amendments to stop the Conservatives turning the UK “into a bargain basement tax haven” and is demanding tariff-free access to the EU. 

Separately, the Liberal Democrats are seeking three main amendments – single market membership, rights for EU nationals and a referendum on the deal, which is a “red line”.

Meanwhile, pro-Remain Tory backbenchers are watching their leadership closely to decide how far to stray from the party line. 

But if the Article 50 ruling has woken Parliament up, the initial reaction has been chaotic rather than collaborative. Despite the Lib Dems’ position as the most UK-wide anti-Brexit voice, neither the SNP nor Labour managed to co-ordinate with them. 

Indeed, the Lib Dems look set to vote against Labour’s tariff-free amendment on the grounds it is not good enough, while expecting Labour to vote against their demand of membership of the single market. 

The question for all opposition parties is whether they can find enough amendments to agree on to force the government onto the defensive. Otherwise, this defeat for the government is hardly a defeat at all.
