Many or us make New Year’s resolutions: going on a diet, doing exercise, spending more time studying. But few people stick to them, even though they say they would like to. So how can people be motivated to keep to their resolutions? Well, the experiments of behavioural economists provide a number of insights into the problem. They also suggest various incentives that can be used to motivate people to stick to their plans.
Central to the problem is that people have ‘time inconsistency’. They put a higher weight on the benefits of things that are good for them in the future and less weight on these benefits when they have to act now. You might strongly believe that going to the gym is good for you and plan to go next Monday. But when Monday comes, you can’t face it.
Another part of the time inconsistency problem is the relatively high weighting given to short-term gratification – eating chocolates, watching TV, spending time on social media, staying in bed. 
When thinking about whether you would like to do these things in, say, a couple of days’ time, you put a low weight on the pleasures. But thinking about doing them right now, you put a much higher weight on them. As the well-known saying goes, ‘Hard work often pays off after time, but laziness pays off now’.
So how can people be motivated to stick to their resolutions? Behavioural economists have studied various systems of incentives to see what works. Some of the findings are as follows:
|
|
| • |
People are generally loss averse. To get us to stick to New Year’s resolutions, we could devise a system of penalties for breaking them, such as paying 20p each time you swear! |
| • |
Given people’s time inconsistency, devising a system whereby you get treats after doing something you feel is good for you: e.g. watching TV for 30 minutes after you’ve done an hour’s revision. Rewards should follow effort, not precede them. |
| • |
Having simple clear goals. Thus rather than merely saying ‘I’ll eat less’, you devise a meal plan with menus that meet calorie and other dietary goals. Rather than saying, ‘I’ll exercise more’, you commit to going to the gym at specific times each week and doing a specific amount of each exercise. |
| • |
Ritualising. This is where you devise a regime that is feasible to stick to. For example, you could always write a shopping list to meet your dietary goals and then only buy what’s on that list; or you and your flatmates could have a rota for household chores. |
| • |
Social reinforcement. This is where people have a joint plan and help each other stick to it, such as going to the gym at specific times with a friend or group of friends, or joining a support group (e.g. to lose weight, or give up drinking or smoking). |
| • |
Avoiding temptation. For example, if you want to give up chocolate, don’t have any in the house. |
| • |
Using praise rather than criticism. People generally respond better to positive incentives than negative ones. |
Behavioural economists test these different incentive mechanisms to see what works best and then to see how they can be refined. The testing could be done experimentally, with volunteers being given different incentives and seeing how they respond. Alternatively, data could be collected on the effects of different incentive mechanisms that people have actually used, whether at home or at work.
The advertising and marketing industry analyses consumer trends and how people respond to pricing, quality, display, packaging, advertising, etc. They want to understand human behaviour so that they can ‘direct’ it in their favour of their clients. Governments too are keen to find ways of encouraging people to do more of things that are good for them and less of things that are bad.
The UK government’s Behavioural Insights Team looks at ways people can be ‘nudged’ into changing their behaviour, see the blog A nudge in the right direction?
But back to New Year’s resolutions, have you made any? And, if so, have you thought about how you might stick to them? Have you thought about the incentives?

Questions
- Explain what is meant by time inconsistent behaviour. Is this the same as giving future costs and benefits a lower weighting than present ones (and hence having to discount future costs and benefits)?
- Give some examples of ways in which your own behaviour exhibits time inconsistency. Would it be accurate to describe this as ‘present bias’?
- Would you describe not sticking to New Year’s resolutions as ‘irrational behaviour’?
- Have you made any New Year’s resolutions, or do you have any plans to achieve goals? Could you alter your own personal incentives and, if so, how, to make it more likely that you will stick to your resolutions/goals?
- Give some examples of ways in which the government could ‘nudge’ us to behave in ways that were more in our own individual interests or those of society or the environment?
- Do you think it’s desirable that the advertising industry should employ psychologists and behavioural economists to help it achieve its goals?
The articles below examine the rise of the sharing economy and how technology might allow it to develop. A sharing economy is where owners of property, equipment, vehicles, tools, etc. rent them out for periods of time, perhaps very short periods. The point about such a system is that the renter deals directly with the property owner – although sometimes initially through an agency. Airbnb and Uber are two examples.
So far the sharing economy has not developed very far. But the development of smart technology will soon make a whole range of short-term renting contracts possible. It will allow the contracts to be enforced without the need for administrators, lawyers, accountants, bankers or the police. Payments will be made electronically and automatically, and penalties, too, could be applied automatically for not abiding by the contract.
One development that will aid this process is a secure electronic way of keeping records and processing payments without the need for a central authority, such as a government, a bank or a company. It involves the use of ‘blockchains‘ (see also). The technology, used in Bitcoin, involves storing data widely across networks, which allows the data to be shared. The data are secure and access is via individuals having a ‘private key’ to parts of the database relevant to them. The database builds in blocks, where each block records a set of transactions. The blocks build over time and are linked to each other in a logical order (i.e. in ‘chains’) to allow tracking back to previous blocks.
Blockchain technology could help the sharing economy to grow substantially. It could significantly cut down the cost of sharing information about possible rental opportunities and demands, and allow minimal-cost secure transactions between owner and renter. As the IBM developerWorks article states:
Rather than use Uber, Airbnb or eBay to connect with other people, blockchain services allow individuals to connect, share, and transact directly, ushering in the real sharing economy. Blockchain is the platform that enables real peer-to-peer transactions and a true ‘sharing economy’.

Can behavioural economics be applied to the case of Sweden? The Swedish government is trying this out by changing government policy in a way that may encourage its residents to change their behaviour.
People in many countries in the world live in what is often called a ‘throwaway society’. If something breaks, it’s often easier and cheaper simply to get rid of it and buy a new one. But with changes in government policy, including VAT cuts on repairs to white goods, the objective is to encourage consumers to repair their goods, rather than buying new ones. This is also contributing towards the wider objective of sustainable consumption, which is being promoted by the Swedish government.
Per Bolund, who is one of Sweden’s six Green Ministers, spoke about this policy commenting that:
“Consumers are quite active in changing both what they buy and how they buy in Sweden … We believe that getting lower costs for labour is a big part in making it more rational to repair rather than just to buy cheap and throw away …If we don’t change the economic incentives the change will never come.”
Whether or not this policy works will take some time to see, but it’s certainly an interesting test of how changing incentives affect consumer behaviour. You can read about other examples of nudging in the following blog A nudge in the right direction?.

Behavioural economists study how people’s buying, selling and other behaviour responds to various incentives and social situations. They don’t accept the simplistic notion that people are always rational maximisers. As the Livemint article below states, “According to behavioural economists, the human brain neither has the time nor the ability to process all the information involved in decision making, as assumed by the rational model.” Instead, rationality is bounded: people use simple rules of thumb in making decisions – rules they have developed over time in the light of experience.
So can people’s behaviour be altered by understanding their limited rationality? Advertisers are only too well aware of a number of psychological ‘tricks’ to change people’s purchasing behaviour. For example, wanting to be approved of by your friends is used by advertisers to sell various fashion products and toiletries. Often, people need only a relatively small ‘nudge’ to change the way they behave.
And it is not just advertisers who are using the insights of behavioural economics. Governments are increasingly trying to find ways of nudging people to behave in ways that are better for themselves or for society.
In 2010, David Cameron set up a ‘Nudge Unit’, formally know as ‘The Behavioural Insights Team‘. It has produced a number of academic papers on topics as diverse as tax compliance, incentives for university attendance, charitable giving in the workplace and using SMS reminders to reduce missed hospital appointments. The academic evidence can then be use as the basis for policy.
Another nudge unit has been set up in Australia (see second article below). The USA, Singapore and various other countries are increasingly using the insights of behavioural economics to devise policy to affect human behaviour.
Two recent pieces of work by the UK team concern ways of discouraging doctors from over-prescribing antibiotics and using encouraging text messages to FE students to reduce dropout rates. Another nudge has been used by the tax authorities (HMRC) who have been sending out texts to remind people to pay their taxes on time and to make them aware that they are being monitored. The message read, “Most people pay on time to avoid penalties”.
The articles below look at these recent initiatives and how human behaviour can be changed in a relatively low-cost way. In most cases this involves a simple nudge.

Questions
- Explain what is meant by bounded rationality.
- Give some examples from your own behaviour of decisions made using rules of thumb.
- Should we abandon models based on the assumption of rational maximising behaviour (e.g. attempts to maximise consumer surplus or to maximise profit)?
- Find out some other examples of how people might be nudged to behave in ways that are in their own interest or that of society.
- How might people be nudged to eat more healthily or to give up smoking?

- Why, do you think, the message by an Australian hospital, “if you attend, the hospital will not lose the $125 we lose when a patient does not turn up” was successful in reducing missed appointments by 20%, while the message, “if you do not attend, the hospital loses $125” was not as effective?
When people think about healthcare in the UK they tend to associate it with the NHS. However, there is a £5 billion private healthcare market. Concerns have been expressed about the lack of effective competition in this sector and it has been investigated by the competition authorities over a 5-year period.
Approximately 4 million people in the UK have a private medical insurance policy. The majority of these are paid for by employers, although some people pay directly. Four companies dominate the health insurance market (AXA PPP, Bupa, Pru Health and Aviva) with a combined market share of over 90%.
Health insurance companies purchase healthcare services for their policy holders from private hospitals. The majority of private hospitals in the UK are owned by the following businesses – BMI, HCA, Nuffield, Ramsey and Spire. Some concerns have been expressed about the lack of competition between private hospitals in some areas of the country.
After its initial analysis into the sector, the Office of Fair Trading (OFT) referred the case to the Competition Commission (CC) in April 2012 to carry out a full market investigation. This process was then taken over by the Competition and Markets Authority (CMA) when it replaced the OFT and CC. The final report was published on April 2nd 2014.
One specific region that was identified in this report as having a lack of effective competition was central London for patients with health insurance. In particular it was concluded that:
|
|
| • |
The market in central London was heavily concentrated and HCA had a dominant market position – its aggregated share of admissions across 16 specialities (e.g. Oncology, Cardiology, Neurology, Dermatology etc.) was 45% to 55%. |
| • |
There were significant barriers to entry including substantial sunk costs. A particular issue for a new entrant or existing business was the problem of securing suitable sites in central London to build new hospitals and in obtaining planning permission. It was pointed out in the report that the market structure in central London had changed very little in the previous 10 years despite a rapidly growing demand for private healthcare. |
| • |
HCA was charging insured patients higher prices for similar treatments than its leading rival – The London Clinic. HCA was also found to be making returns that were in excess of the cost of capital. |
One of the key recommendations of the report was that HCA should be forced to sell–off one or two of the hospitals that it owned in central London to increase the level of competition.
Unsurprisingly HCA was very unhappy with the decision and applied to the Competition Appeal Tribunal (CAT) for a review of the case. During this review, economists working for HCA found errors with the analysis carried out by the CMA into the pricing of health services for insured customers.
In January 2015 the CAT concluded that the findings and recommendations of the report on insured patients in central London should be overturned and the CMA should reconsider the case. In November 2015 the CMA announced that having reviewed the case it had come to a similar set of conclusions: i.e. there was a lack of effective competition and HCA should be forced to sell off two of its hospitals in London.
HCA still claimed that the pricing analysis was incorrect because it did not fully take into account that HCA treated patients with more complex conditions than TLC and that was why their prices were higher.
On March 22nd 2016 the CMA announced that it had reversed its ruling and HCA would no longer be expected to sell off any of its hospitals. The reason given for this change in recommendation was the appearance of new entrants into the market. For example, Cleveland Clinic a US-based private healthcare provider has purchased a long-term lease on a property in Belgravia, central London. It plans to convert the office space into a private hospital with 2015 beds.
A spokesperson for Bupa commented that:
“The CMA has confirmed again that there isn’t enough competition in central London, with HCA dominating the private hospital market and charging higher prices. We ask the CMA to act now to address this gap.”
It will be interesting to see the impact these new entrants have on the market in the future.
