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.

Let's turn RBS into a bank for the public interest

A tarnished symbol of global finance could be remade as a network of local banks. 

The Royal Bank of Scotland has now been losing money for nine consecutive years. Today’s announcement of a further £7bn yearly loss at the publicly-owned bank is just the latest evidence that RBS is essentially unsellable. The difference this time is that the Government seems finally to have accepted that fact.

Up until now, the government had been reluctant to intervene in the running of the business, instead insisting that it will be sold back to the private sector when the time is right. But these losses come just a week after the government announced that it is abandoning plans to sell Williams & Glynn – an RBS subsidiary which has over 300 branches and £22bn of customer deposits.

After a series of expensive delays and a lack of buyer interest, the government now plans to retain Williams & Glynn within the RBS group and instead attempt to boost competition in the business lending market by granting smaller "challenger banks" access to RBS’s branch infrastructure. It also plans to provide funding to encourage small businesses to switch their accounts away from RBS.

As a major public asset, RBS should be used to help achieve wider objectives. Improving how the banking sector serves small businesses should be the top priority, and it is good to see the government start to move in this direction. But to make the most of RBS, they should be going much further.

The public stake in RBS gives us a unique opportunity to create new banking institutions that will genuinely put the interests of the UK’s small businesses first. The New Economics Foundation has proposed turning RBS into a network of local banks with a public interest mandate to serve their local area, lend to small businesses and provide universal access to banking services. If the government is serious about rebalancing the economy and meeting the needs of those who feel left behind, this is the path they should take with RBS.

Small and medium sized enterprises are the lifeblood of the UK economy, and they depend on banking services to fund investment and provide a safe place to store money. For centuries a healthy relationship between businesses and banks has been a cornerstone of UK prosperity.

However, in recent decades this relationship has broken down. Small businesses have repeatedly fallen victim to exploitative practice by the big banks, including the the mis-selling of loans and instances of deliberate asset stripping. Affected business owners have not only lost their livelihoods due to the stress of their treatment at the hands of these banks, but have also experienced family break-ups and deteriorating physical and mental health. Others have been made homeless or bankrupt.

Meanwhile, many businesses struggle to get access to the finance they need to grow and expand. Small firms have always had trouble accessing finance, but in recent decades this problem has intensified as the UK banking sector has come to be dominated by a handful of large, universal, shareholder-owned banks.

Without a focus on specific geographical areas or social objectives, these banks choose to lend to the most profitable activities, and lending to local businesses tends to be less profitable than other activities such as mortgage lending and lending to other financial institutions.

The result is that since the mid-1980s the share of lending going to non-financial businesses has been falling rapidly. Today, lending to small and medium sized businesses accounts for just 4 per cent of bank lending.

Of the relatively small amount of business lending that does occur in the UK, most is heavily concentrated in London and surrounding areas. The UK’s homogenous and highly concentrated banking sector is therefore hampering economic development, starving communities of investment and making regional imbalances worse.

The government’s plans to encourage business customers to switch away from RBS to another bank will not do much to solve this problem. With the market dominated by a small number of large shareholder-owned banks who all behave in similar ways (and who have been hit by repeated scandals), businesses do not have any real choice.

If the government were to go further and turn RBS into a network of local banks, it would be a vital first step in regenerating disenfranchised communities, rebalancing the UK’s economy and staving off any economic downturn that may be on the horizon. Evidence shows that geographically limited stakeholder banks direct a much greater proportion of their capital towards lending in the real economy. By only investing in their local area, these banks help create and retain wealth regionally rather than making existing geographic imbalances worce.

Big, deep challenges require big, deep solutions. It’s time for the government to make banking work for small businesses once again.
