Economic forecasting came in for much criticism at the time of the financial crisis and credit crunch. Few economists had predicted the crisis and its consequences. Even Queen Elizabeth II, on a visit to the London School of Economics in November 2008, asked why economists had got it so wrong. Similar criticisms have emerged since the Brexit vote, with economic forecasters being accused of being excessively pessimistic about the outcome.
The accuracy of economic forecasts was one of the topics discussed by Andy Haldane, Chief Economist at the Bank of England. Speaking at the Institute for Government in London, he compared economic forecasting to weather forecasting (see section from 15’20” in the webcast):
“Remember that? Michael Fish getting up: ‘There’s no hurricane coming but it will be very windy in Spain.’ Very similar to the sort of reports central banks – naming no names – issued pre-crisis, ‘There is no hurricane coming but it might be very windy in the sub-prime sector.” (18’40”)
The problem with the standard economic models which were used for forecasting is that they were essentially equilibrium models which work reasonably well in ‘normal’ times. But when there is a large shock to the economic system, they work much less well. First, the shocks themselves are hard to predict. For example, the sub-prime crisis in 2007/8 was not foreseen by most economists.
Then there is the effect of the shocks. Large shocks are much harder to model as they can trigger strong reactions by consumers and firms, and governments too. These reactions are often hugely affected by sentiment. Bouts of pessimism or even panic can grip markets, as happened in late 2008 with the collapse of Lehman Brothers. Markets can tumble way beyond what would be expected by a calm adjustment to a shock.
It can work the other way too. Economists generally predicted that the Brexit vote would lead to a fall in GDP. However, despite a large depreciation of sterling, consumer sentiment held up better than was expected and the economy kept growing.
But is it fair to compare economic forecasting with weather forecasting? Weather forecasting is concerned with natural phenomena and only seeks to forecast with any accuracy a few days ahead. Economic forecasting, if used correctly, highlights the drivers of economic change, such as government policy or the Brexit vote, and their likely consequences, other things being equal. Given that economies are constantly being affected by economic shocks, including government or central bank actions, it is impossible to forecast the state of the macroeconomy with any accuracy.
This does not mean that forecasting is useless, as it can highlight the likely effects of policies and take into account the latest surveys of, say, consumer and business confidence. It can also give the most likely central forecast of the economy and the likely probabilities of variance from this central forecast. This is why many forecasts use ‘fan charts’: see, for example, Bank of England forecasts.
What economic forecasts cannot do is to predict the precise state of the economy in the future. However, they can be refined to take into account more realistic modelling, including the modelling of human behaviour, and more accurate data, including survey data. But, however refined they become, they can only ever give likely values for various economic variables or likely effects of policy measures.

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 economic climate remains uncertain and, as we enter 2017, we look towards a new President in the USA, challenging negotiations in the EU and continuing troubles for High Street stores. One such example is Next, a High Street retailer that has recently seen a significant fall in share price.
Prices of clothing and footwear increased in December for the first time in two years, according to the British Retail Consortium, and Next is just one company that will suffer from these pressures. This retail chain is well established, with over 500 stores in the UK and Eire. It has embraced the internet, launching its online shopping in 1999 and it trades with customers in over 70 countries. However, despite all of the positive actions, Next has seen its share price fall by nearly 12% and is forecasting profits in 2017 to be hit, with a lack of growth in earnings reducing consumer spending and thus hitting sales.
The sales trends for Next are reminiscent of many other stores, with in-store sales falling and online sales rising. In the days leading up to Christmas, in-store sales fell by 3.5%, while online sales increased by over 5%. However, this is not the only trend that this latest data suggests. It also indicates that consumer spending on clothing and footwear is falling, with consumers instead spending more money on technology and other forms of entertainment. Kirsty McGregor from Drapers magazine said:
“I think what we’re seeing there is an underlying move away from spending so much money on clothing and footwear. People seem to be spending more money on going out and on technology, things like that.”
Furthermore, with price inflation expected to rise in 2017, and possibly above wage inflation, spending power is likely to be hit and it is spending on those more luxury items that will be cut. With Next’s share price falling, the retail sector overall was also hit, with other companies seeing their share prices fall as well, although some, such as B&M, bucked the trend. However, the problems facing Next are similar to those facing other stores.
But for Next there is more bad news. It appears that the retail chain has simply been underperforming for some time. We have seen other stores facing similar issues, such as BHS and Marks & Spencer. Neil Wilson from ETX Capital said:
“The simple problem is that Next is underperforming the market … UK retail sales have held up in the months following the Brexit vote but Next has suffered. It’s been suffering for a while and needs a turnaround plan … The brand is struggling for relevancy, and risks going the way of Marks & Spencer on the clothing front, appealing to an ever-narrower customer base.”
Brand identity and targeting customers are becoming ever more important in a highly competitive High Street that is facing growing competition from online traders. Next is not the first company to suffer from this and will certainly not be the last as we enter what many see as one of the most economically uncertain years since the financial crisis.

- Why have shares in other retail companies also been affected following Next’s report on its profit forecast for 2017?
- Which factors have adversely affected Next’s performance over the past year? Are they the same as the factors that have affected Marks & Spencer?
- Next has seen a fall in profits. What is likely to have caused this?
- How competitive is the UK High Street? What type of market structure would you say that it fits into?
- With rising inflation expected, what will this mean for consumer spending? How might this affect economic growth?
- One of the factors affecting Next is higher import prices. Why have import prices increased and what will this mean for consumer spending and sales?
Household borrowing on credit cards and through overdrafts and loans has been growing rapidly. This ‘unsecured’ borrowing is now rising at rates not seen since well before the credit crunch of 2008 (click here for a PowerPoint of the chart below). Should this be a cause for concern?
Household confidence is generally high and, as a result, people continue to take out more loans and so household debt continues to increase. Saving rates are falling and, at 5.1% of household disposable income, are the lowest rate since 2008, mirroring the high levels of spending and borrowing.
But as long as the economy keeps growing and as long as interest rates stay at record low levels, people should be able to continue servicing this rising debt. Indeed, with generous balance transfer offers between credit cards and many people paying off their full balance each month, only 56.6% are paying any interest at all on credit card debt, the lowest level on record.
But there could be trouble ahead! Secured borrowing (i.e. on mortgages) is at record highs as house prices have soared, limiting the amount people have to left to spend, even with ultra low interest rates. Student debt is growing, putting a brake on graduate spending.
With economic growth set to slow and inflation set to rise as the effects of the lower pound filter through into retail prices, this could initially boost borrowing further as people seek to maintain levels of consumption. But then, if unemployment starts to rise and consumer confidence starts to fall, real spending could decline, putting further downward pressure on the economy.
Confidence could then fall further and we could witness a repeat of 2008–9, when people became worried about their levels of borrowing and cut back on consumption in an attempt to claw down their debt. The economy was pushed into recession.
The Bank of England is well aware of this scenario and wants banks to ensure that their customers can afford loans before offering them.

On 14 December, the US Federal Reserve announced that its 10-person Federal Open Market Committee (FOMC) had unanimously decided to raise the Fed’s benchmark interest rate by 25 basis points to a range of between 0.5% and 0.75%. This is the first rise since this time last year, which was the first rise for nearly 10 years.
The reasons for the rise are two-fold. The first is that the US economy continues to grow quite strongly, with unemployment edging downwards and confidence edging upwards. Although the rate of inflation is currently still below the 2% target, the FOMC expects inflation to rise to the target by 2018, even with the rate rise. As the Fed’s press release states:
Inflation is expected to rise to 2% over the medium term as the transitory effects of past declines in energy and import prices dissipate and the labor market strengthens further.
The second reason for the rate rise is the possible fiscal policy stance of the new Trump administration. 
If, as expected, the new president adopts an expansionary fiscal policy, with tax cuts and increased government spending on infrastructure projects, this will stimulate the economy and put upward pressure on inflation. It could also mean that the Fed will raise interest rates again more quickly. Indeed, the FOMC indicated that it expects three rate rises in 2017 rather than the two it predicted in September.
However, just how much and when the Fed will raise interest rates again is highly uncertain. Future monetary policy measures will only become more predictable when Trump’s policies and their likely effects become clearer.
