The annual Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, normally known as the Nobel Prize in Economics, has been awarded 49 times since it was founded in 1969. Many well-known economists have been recipients of the award. This year it had been awarded to Richard Thaler for his research in behavioural economics. The award recognises his work in integrating economics with psychology.

Richard H. Thaler has incorporated psychologically realistic assumptions into analyses of economic decision-making. By exploring the consequences of limited rationality, social preferences, and lack of self-control, he has shown how these human traits systematically affect individual decisions as well as market outcomes.

In total, Richard Thaler’s contributions have built a bridge between the economic and psychological analyses of individual decision-making. His empirical findings and theoretical insights have been instrumental in creating the new and rapidly expanding field of behavioural economics, which has had a profound impact on many areas of economic research and policy.

Instead of making the assumption that people are rational maximisers, behavioural economists look at how people actually behave and respond to various incentives.

For example, people may be motivated by concepts of fairness and be prepared to make personal sacrifices for the sake of others. Such concepts of fairness tend to depend on the social context in which choices are made and can be influenced by the way choices are framed.

Also people may not weigh up costs and benefits but use simple rules of thumb, or heuristics, when making decisions. This might be an example of rational behaviour when time or information is limited, but the use of such heuristics often becomes engrained in behaviour and the rules become just habit.

People may also suffer from a lack of willpower or ‘present bias’. They may spend more than they can afford because they cannot resist the temptation to have a product. They may overeat because of the short-term pleasure it brings and ignore the long-term effects on their health.

Understanding how people make choices and the temptations to which they succumb can help policymakers devise incentives to change behaviour to achieve various social goals.

One type of incentive is nudging. A well-known example is people’s choice about whether to become an organ donor in the event of their death. If people are required to opt in to such a scheme, they may never get round to doing so. However, if they are required to opt out if they do not want to participate, many more people would thereby be donors and more organs would become available.

Another form of nudge is making desirable things fun. A well-known experiment here was encouraging people to use the stairs rather than the escalator when exiting a subway by making the stairs like a musical keyboard. See here for more examples.

The UK government set up a Behavioural Insights Team – also known as the Nudge Unit (now independent of government) to find ways of encouraging people to behave in their own or society’s best interests.

But it is not just governments which use the insights of behavioural economists such as Thaler. The advertising and marketing industry is always examining the most effective means of influencing behaviour. A classic example is the loss leader, where consumers are tempted into a shop with a special offer and then end up buying more expensive items there rather than elsewhere.

Firms and advertisers know only too well the gains from tempting people to buy items that give them short-term gratification – such as putting chocolate bars by the tills in supermarkets.

Understanding consumer psychology helps firms to manipulate people’s choices. And such manipulation may not be in our best interests. If we are being persuaded to buy this product or that, are we fully aware of what’s going on and how our tastes are being affected? Would we, by standing back and reflecting, make the same choices as we do on impulse or out of habit?

And governments too can seek to manipulate people in ways that some may find undesirable. Governments may try to influence us to follow their particular political agenda – as may newspapers. Certainly, during election or referendum campaigns, we are being nudged to vote a particular way.

It is important then for us to understand when we are being nudged or otherwise persuaded. Do we really want to behave in that way? Just as it is important, then, for governments and firms to understand individuals’ behaviour, so too it is important for individuals to understand their own behaviour.

Ten years ago (on 9 August 2007), the French bank BNP Paribas sparked international concern when it admitted that it didn’t know what many of its investments in the US sub-prime property market were worth and froze three of its hedge funds. This kicked off the financial crisis and the beginning of the credit crunch.

In September 2007 there was a run on the Northern Rock bank in the UK, forcing the Bank of England to provide emergency funding. Northern Rock was eventually nationalised in February 2008. In July 2008, the US financial authorities had to provide emergency assistance to America’s two largest mortgage lenders, Fannie Mae and Freddie Mac.

Then in September 2008, the financial crisis really took hold. The US bank, Lehman Brothers, filed for bankruptcy, sending shock waves around the global economy. In the UK, Lloyds TSB announced that it was taking over the UK’s largest mortgage lender, Halifax Bank Of Scotland (HBOS), after a run on HBOS shares.

Later in the month, Fortis, the huge Belgian banking, finance and insurance company, was partly nationalised to prevent its bankruptcy. Also the UK government was forced to take control of mortgage-lender, Bradford & Bingley’s, mortgages and loans, with the rest of the business sold to Santander.

Early in October 2008, trading was suspended in the main Icelandic banks. Later in the month, the UK government announced a £37 billion rescue package for Royal Bank of Scotland (RBS), Lloyds TSB and HBOS. Then in November it partially nationalised RBS by taking a 58% share in the bank. Meanwhile various other rescue packages and emergency loans to the banking sector were taking place in other parts of the world. See here for a timeline of the financial crisis.

So, ten years on from the start of the crisis, have the lessons of the crisis been learnt. Could a similar crisis occur again?

The following articles look at this question and the answers are mixed.

On the positive side, banks are much more highly capitalised than they were ten years ago. Moves by the Basel Committee on Banking Supervision in its Basel III regulatory framework have ensured that banks are much more highly capitalised and operate with higher levels of liquidity. What is more, banks are generally more cautious about investing in highly complex and risky collateralised assets.

On the negative side, increased flexibility in labour markets, although helping to keep unemployment down, has allowed a huge squeeze on real wages as austerity measures have dampened the economy. What is more, household debt is rising to possibly unsustainable levels. Over the past year, unsecured debt (e.g. personal loans and credit card debt) have risen by 10% and yet (nominal) household incomes have risen by only 1.5%. While record low interest rates make such loans relatively affordable, when interest rates do eventually start to rise, this could put a huge strain on household finances. But if households start to rein in their borrowing, this would put downward pressure on aggregate demand and jeopardise economic growth.

Following concerns about the market power of the Big Six energy suppliers in the UK and high prices for gas and electricity, the industry regulator, Ofgem, referred the industry to the Competition and Markets Authority (CMA) in June 2014. The CMA published its final report in June 2016. This argued that while there was sufficient potential for competition, consumers nevertheless needed further encouragement to switch suppliers. This would strengthen competition in the market.

To encourage switching, the CMA proposed the creation of a database that would include the details of customers who have been on a supplier’s standard variable tariff (SVT) for three or more years. Competitor energy suppliers would have access to this database to offer better deals for these customers.

There had already been calls for price caps to be imposed on suppliers. For example, in the run-up to the 2015 general election, the then Labour leader, Ed Miliband, proposed imposing a price freeze. This was criticised by the Conservatives for being too anti-market, that it would encourage energy companies to raise prices prior to the freeze and that it would be of no benefit in times of falling wholesale energy prices (which was the position in 2015).

Indeed, in its 2016 report, the CMA recommended price caps only for the 16% of people on prepayment meters and these would be variable caps not freezes. This was followed in February 2017, by Ofgem’s announcement that a temporary price cap for such customers would come into effect in April 2017. The level of the cap would vary by meter type and region. It would also be reviewed every six months to reflect changes in costs and remain in place until 2020. There would be no cap on other customers.

But in the run-up to the 2017 election, the Conservatives announced that they would, after all, introduce a price cap on SVTs – 66% of customers are on such tariffs. Before the details were announced, there was much speculation as to what form such a cap would take? It would not be a simple freeze. But there was debate as to whether caps would vary with wholesale costs or whether they would be relative to the company’s lowest tariffs or to those of its rivals.

As it turned out, the proposal was for a cap on standard variable tariffs. It would be set by Ofgem and reviewed every six months. The cap would be based on the cheapest standard variable tariffs in each part of the UK, taking into account the variable costs for transporting energy there. Ofgem will adjust the cap every six months to reflect changes in the wholesale cost of energy.

The latest figures from the ONS show that UK inflation rose to 2.3% for the 12 months to February 2017 – up from 1.9% for the 12 months to January. The rate is the highest since September 2013 and has steadily increased since late 2015.

The main price index used to measure inflation is now CPIH, as opposed to CPI. CPIH is the consumer prices index (CPI) adjusted for housing costs and is thus a more realsitic measure of the cost pressures facing households. As the ONS states:

CPIH extends the consumer prices index (CPI) to include a measure of the costs associated with owning, maintaining and living in one’s own home, known as owner occupiers’ housing costs (OOH), along with Council Tax. Both of these are significant expenses for many households and are not included in the CPI.

But why has inflation risen so significantly? There are a number of reasons.

The first is a rise in transport costs (contributing 0.15 percentage points to the overall inflation rate increase of 0.4 percentage points). Fuel prices rose especially rapidly, reflecting both the rise in the dollar price of oil and the depreciation of the pound. In February 2016 the oil price was $32.18; in February 2017 it was $54.87 – a rise of 70.5%. In February 2016 the exchange rate was £1 = $1.43; in February 2017 it was £1 = $1.25 – a depreciation of 12.6%.

The second biggest contributor to the rise in inflation was recreation and culture (contributing 0.08 percentage points). A wide range of items in this sector, including both goods and services, rose in price. ‘Notably, the price of personal computers (including laptops and tablets) increased by 2.3% between January 2017 and February 2017.’ Again, a large contributing factor has been the fall in the value of the pound. Apple, for example, raised its UK app store prices by a quarter in January, having raised prices for iPhones, iPads and Mac computers significantly last autumn. Microsoft has raised its prices by more than 20% this year for software services such as Office and Azure. Dell, HP and Tesla have also significantly raised their prices.

The third biggest was food and non-alcoholic beverages (contributing 0.06 percentage points). ‘Food prices, overall, rose by 0.8% between January 2017 and February 2017, compared with a smaller rise of 0.1% a year earlier.’ Part of the reason has been the fall in the pound, but part has been poor harvests in southern Europe putting up euro prices. This is the first time that overall food prices have risen for more than two-and-a-half years.

It is expected that inflation will continue to rise over the coming months as the effect of the weaker pound and higher raw material and food prices filter though. The current set of pressures could see inflation peaking at around 3%. If there is a futher fall in the pound or further international price increases, inflation could be pushed higher still – well above the Bank of England’s 2% target. (Click here for a PowerPoint of the chart.)

The higher inflation means that firms are facing a squeeze on their profits from two directions.

First, wage rises have been slowing and are now on a level with consumer price rises. It is likely that wage rises will soon drop below price rises, meaning that real wages will fall, putting downward pressure on spending and squeezing firms’ revenue.

Second, input prices are rising faster than consumer prices. In the 12 months to February 2017, input prices (materials and fuels) rose by 19.1%, putting a squeeze on producers. Producer prices (‘factory gate prices’), by contrast, rose by 3.7%. Even though input prices are only part of the costs of production, the much smaller rise of 3.7% reflects the fact that producer’s margins have been squeezed. Retailers too are facing upward pressure on costs from this 3.7% rise in the prices of products they buy from producers.

One of the worries about the squeeze on real wages and the squeeze on profits is that this could dampen investment and slow both actual and potential growth.

So will the Bank of England respond by raising interest rates? The answer is probably no – at least not for a few months. The reason is that the higher inflation is not the result of excess demand and the economy ‘overheating’. In other words, the higher inflation is not from demand-pull pressures. Instead, it is from higher costs, which are in themselves likely to dampen demand and contribute to a slowdown. Raising interest rates would cause the economy to slow further.

Economists were generally in favour of the UK remaining in the EU and highly critical of the policy proposals of Donald Trump. And yet the UK voted to leave the EU and Donald Trump was elected.

People rejected the advice of most economists. Many blamed the failure of most economists to predict the 2007/8 financial crisis and to find solutions to the growing gulf between rich and poor, with the majority stuck on low incomes.

So to what extent are economists to blame for the rise in populism – a wave that could lead to electoral upsets in various European countries? The podcast below brings together economists and politicians from across the political spectrum. It is over an hour long and provides an in-depth discussion of many of the issues and the extent to which economists can provide answers.
