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.

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.

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.

We’ve considered Keynesian economics and policy in several blogs. For example, a year ago in the post, What would Keynes say?, we looked at two articles arguing for Keynesian expansionary polices. More recently, in the blogs, End of the era of liquidity traps? and A risky dose of Keynesianism at the heart of Trumponomics, we looked at whether Donald Trump’s proposed policies are more Keynesian than his predecessor’s and at the opportunities and risks of such policies.
The article below, Larry Elliott updates the story by asking what Keynes would recommend today if he were alive. It also links to two other articles which add to the story.
Elliott asks his imaginary Keynes, for his analysis of the financial crisis of 2008 and of what has happened since. Keynes, he argues, would explain the crisis in terms of excessive borrowing, both private and public, and asset price bubbles. The bubbles then burst and people cut back on spending to claw down their debts.
Keynes, says Elliott, would approve of the initial response to the crisis: expansionary monetary policy (both lower interest rates and then quantitative easing) backed up by expansionary fiscal policy in 2009. But expansionary fiscal policies were short lived. Instead, austerity fiscal policies were adopted in an attempt to reduce public-sector deficits and, ultimately, public-sector debt. This slowed down the recovery and meant that much of the monetary expansion went into inflating the prices of assets, such as housing and shares, rather than in financing higher investment.
He also asks his imaginary Keynes what he’d recommend as the way forward today. Keynes outlines three alternatives to the current austerity policies, each involving expansionary fiscal policy:
|
|
| • |
Trump’s policies of tax cuts combined with some increase in infrastructure spending. The problems with this are that there would be too little of the public infrastructure spending that the US economy needs and that the stimulus would be poorly focused. |
| • |
Government taking advantage of exceptionally low interest rates to borrow to invest in infrastructure. “Governments could do this without alarming the markets, Keynes says, if they followed his teachings and borrowed solely to invest.” |
| • |
Use money created through quantitative easing to finance public-sector investment in infrastructure and housing. “Building homes with QE makes sense; inflating house prices with QE does not.” (See the blogs, A flawed model of monetary policy and Global warning). |
Increased government spending on infrastructure has been recommended by international organisations, such as the OECD and the IMF (see OECD goes public and The world economic outlook – as seen by the IMF). With the rise in populism and worries about low economic growth throughout much of the developed world, perhaps Keynesian fiscal policy will become more popular with governments.

Keynesian economics: is it time for the theory to rise from the dead?, The Guardian, Larry Elliott (11/12/16)
Questions
- What are the main factors determining a country’s long-term rate of economic growth?
- What are the benefits and limitations of using fiscal policy to raise global economic growth?
- What are the benefits and limitations of using new money created by the central bank to fund infrastructure spending?
- Draw an AD/AS diagram to illustrate the effect of a successful programme of public-sector infrastructure projects on GDP and prices.
- Draw a Keynesian 45° line diagram to illustrate the effect of a successful programme of public-sector infrastructure projects on actual and potential GDP.
- Why might an individual country benefit more from a co-ordinated expansionary fiscal policy of all countries rather than being the only country to pursue such a policy?
- Compare the relative effectiveness of increased government investment in infrastructure and tax cuts as alterative forms of expansionary fiscal policy.
- What determines the size of the multiplier effect of such policies?
- What supply-side policies could the government adopt to back up monetary and fiscal policy? Are the there lessons here from the Japanese government’s ‘three arrows’?
The first article below, from The Economist, examines likely macroeconomic policy under Donald Trump. He has stated that he plans to cut taxes, including reducing the top rates of income tax and reducing taxes on corporate income and capital gains. At the same time he has pledged to increase infrastructure spending.
This expansionary fiscal policy is unlikely to be accompanied by accommodating monetary policy. Interest rates would therefore rise to tackle the inflationary pressures from the fiscal policy. One effect of this would be to drive up the dollar and therein lies significant risks.
The first is that the value of dollar-denominated debt would rise in foreign currency terms, thereby making it difficult for countries with high levels of dollar debt to service those debts, possibly leading to default and resulting international instability. At the same time, a rising dollar may encourage capital 
flight from weaker countries to the US (see The Economist article, ‘Emerging markets: Reversal of fortune’).
The second risk is that a rising dollar would worsen the US balance of trade account as US exports became less competitive and imports became more so. This may encourage Donald Trump to impose tariffs on various imports – something alluded to in campaign speeches. But, as we saw in the blog, Trump and Trade, “With complex modern supply chains, many products use components and services, such as design and logistics, from many different countries. Imposing restrictions on imports may lead to damage to products which are seen as US products”.
The third risk is that the main beneficiaries of Trump’s likely fiscal measures will be the rich, who would end up paying significantly less tax. With all the concerns from poor Americans, including people who voted for Trump, about growing inequality, measures that increase this inequality are unlikely to prove popular.
