With the prospects of weaker global economic growth and continuing worries about trade wars, central banks have been loosening monetary policy. The US central bank, the Federal Reserve, lowered its target Federal Funds rate in both July and September. Each time it reduced the rate by a quarter of a percentage point, so that it now stands at between 1.75% and 2%.

The ECB has also cut rates. In September it reduced the overnight deposit rate for banks from –0.4% to –0.5%, leaving the main rate at 0%. It also introduced a further round of quantitative easing, with asset purchases of €20 billion per month from 1 November and lasting until the ECB starts raising interest rates.

The Australian Reserve Bank has cut its ‘cash rate‘ three times this year and it now stands at an historically low level of 0.75%. Analysts are predicting that it may be forced to introduce quantitative easing if lower interest rates fail to stimulate growth.

Japan continues with its programme of quantitative easing (QE) and other central banks are considering lowering interest rates and/or (further) QE.

But there are two key issues with looser monetary policy.

The first is whether it will be sufficient to provide the desired stimulus. With interest rates already at or near historic lows (although slightly above in the case of the USA), there is little scope for further reductions. QE may help, but without a rise in confidence, the main effect of the extra money may simply be a rise in the price of assets, such as property and shares. It may result in very little extra spending on consumption and investment – in other words, very little extra aggregate demand.

The second is the effect on inequality. By inflating asset prices, QE rewards asset owners. The wealthier people are, the more they will gain.

Many economists and commentators are thus calling for the looser monetary policy to be backed up by expansionary fiscal policy. The boost to aggregate demand, they argue, should come from higher public spending, with governments able to borrow at very low interest rates because of the loose monetary policy. Targeted spending on infrastructure would have a supply-side benefit as well as a demand-side one.

There is increasing recognition that the world is facing a climate emergency. Concerns are growing about the damaging effects of global warming on weather patterns, with increasing droughts, forest fires, floods and hurricanes. Ice sheets are melting and glaciers retreating, with consequent rising sea levels. Habitats and livelihoods are being destroyed. And many of the effects seem to be occurring more rapidly than had previously been expected.

Extinction Rebellion has staged protests in many countries; the period from 20 to 27 September saw a worldwide climate strike (see also), with millions of people marching and children leaving school to protest; a Climate Action Summit took place at the United Nations, with a rousing speech by Greta Thunberg, the 16 year-old Swedish activist; the UN’s Intergovernmental Panel on Climate Change (IPCC) has just released a report with evidence showing that the melting of ice sheets and rising sea levels is more rapid than previously thought; at its annual party conference in Brighton, the Labour Party pledged that, in government, it would bring forward the UK’s target for zero net carbon emissions from 2050 to 2030.

Increasingly attention is focusing on what can be done. At first sight, it might seem as if the answer lies solely with climate scientists, environmentalists, technologists, politicians and industry. When the matter is discussed in the media, it is often the environment correspondent, the science correspondent, the political correspondent or the business correspondent who reports on developments in policy. But economics has an absolutely central role to play in both the analysis of the problem and in examining the effectiveness of alternative solutions.

One of the key things that economists do is to examine incentives and how they impact on human behaviour. Indeed, understanding the design and effectiveness of incentives is one of the 15 Threshold Concepts we identify in the Sloman books.

One of the most influential studies of the impact of climate change and means of addressing it was the study back in 2006, The Economics of Climate Change: The Stern Review, led by the economist Sir Nicholas Stern. The Review reflected economists’ arguments that climate change represents a massive failure of markets and of governments too. Firms and individuals can emit greenhouse gases into the atmosphere at no charge to themselves, even though it imposes costs on others. These external costs are possible because the atmosphere is a public good, which is free to exploit.

Part of the solution is to ‘internalise’ these externalities by imposing charges on people and firms for their emissions, such as imposing higher taxes on cars with high exhaust emissions or on coal-fired power stations. This can be done through the tax system, with ‘green’ taxes and charges. Economists study the effectiveness of these and how much they are likely to change people’s behaviour.

Another part of the solution is to subsidise green alternatives, such as solar and wind power, that provide positive environmental externalities. But again, just how responsive will demand be? This again is something that economists study.

Of course, changing human behaviour is not just about raising the prices of activities that create negative environmental externalities and lowering the prices of those that create positive ones. Part of the solution lies in education to make people aware of the environmental impacts of their activities and what can be done about it. The problem here is that there is a lack of information – a classic market failure. Making people aware of the consequences of their actions can play a key part in the economic decisions they make. Economists study the extent that imperfect information distorts decision making and how informed decision making can improve outcomes.

Another part of the solution may be direct government investment in green technologies or the use of legislation to prevent or restrict activities that contribute to global warming. But in each case, economists are well placed to examine the efficacy and the costs and benefits of alternative policies. Economists have the tools to make cost–benefit appraisals.

Economists also study the motivations of people and how they affect their decisions, including decisions about whether or not to take part in activities with high emissions, such air travel, and decisions on ‘green’ activities, such as eating less meat and more vegetables.

If you are starting out on an economics degree, you will soon see that economists are at the centre of the analysis of some of the biggest issues of the day, such as climate change and the environment generally, inequality and poverty, working conditions, the work–life balance, the price of accommodation, the effects of populism and the retreat from global responsibility and, in the UK especially, the effects of Brexit, of whatever form.

  4. In what ways would you suggest incentivising (a) individuals and (b) firms to reduce carbon emissions? Explain your reasoning.
  5. For what reasons are the burdens of climate changed shared unequally between people across the globe?

Many of you may have heard of nudge – the idea that governments can help people make better decisions by carefully designing the way a policy is structured and presented. Have you heard of sludge?

The most widely cited example of a nudge is changing a default option. The default option is what happens if you do nothing. For example, when you start a new job, are you automatically enrolled into the pension scheme or do you have to do something (i.e. fill-in an on-line form) to opt-in to the scheme. Changing the default option to one of being automatically enrolled in a scheme seems to have a big impact on the choices people make.

Recently, policy makers have started referring to ‘sludge’. Sludge is the opposite of nudge: i.e. characteristics about design and presentation that make it more difficult for people to make good decisions. Some businesses may use sludge to encourage consumers to spend more on their goods than they ever intended.

One interesting application of sludge is in the design of websites – referred to as Dark Patterns. The following are a number of different categories of dark pattern:

The last example, Forced Continuity, refers to the use of free trial periods and automatic renewal of contracts. Many people sign up for a free trial or special offer with the full intention of cancelling before the account automatically switches to the standard price.

How often do people simply forget or never quite get around to cancelling these deals when the time comes? Some recent evidence comes from a YouGov Survey. Forty-seven percent of respondents to this survey reported having accidently signed up for an annual subscription because they either forgot or were unable to cancel their account. The estimated total cost of unwanted subscriptions per year was £837 million. The same YouGov survey found that one in eight people kept paying for over four months before finally getting around to cancelling.

One business has recently seen an opportunity to help people deal with this problem. Free Trial Surfing is a new App developed by the company, Do Not Pay. It became available via Apple’s App store in September but is not yet compatible with Android devices. It works in the following way.

When customers download the app, they receive a new credit card number and a false name. Although Do Not Pay register the card details to their own business, the customer can use the information to sign up for a free trial of a good or service. In effect, Do Not Pay acts as an intermediary between the firm offering the promotion and the user. Once the free trial period ends, the app automatically cancels the subscription. Importantly, the new credit card details only work when someone signs up for a free trial. Consumers cannot use it to purchase any other products. Obviously one major drawback to the app is that a consumer would have to sign up again with their own personal credit card if they wanted to continue to use the service after the free trial ends. Businesses may also try to block the use of Do Not Pay credit card numbers for their services.

It will be interesting to see if other businesses come up with interesting ways of helping us to deal with sludge.

With university fees for home students in England of £9250 per year and with many students receiving maintenance loans of around £9000 per year, many students are graduating with debts in excess of £50 000. Loans are repaid at a marginal rate of 9% on incomes over £25 716.

Many students also study for a masters degree. The average fee for a taught, classroom-based masters (MA) is £7392 and for a laboratory-based masters (MSc) is £8167 but can be considerably higher at some prestigious universities where demand is high. Government loans of up to £10 906 are available to contribute towards fees and maintenance. These are paid back at a marginal rate of 6% for people earning over £21 000, giving a combined marginal rate of 15% for first and masters degrees.

For high earners on the 40% income tax rate, the combined marginal rate of payment out of income is 40% tax, plus 2% national insurance, plus 15% for those with undergraduate and masters loans. This gives a combined marginal rate of 57%.

Average student debt in England is higher even than in the USA, where the average is $37 000. US university courses are more expensive than in the UK, costing an average of $34 000 per year in tuition alone. But undergraduates can borrow less. They can borrow between $5500 and $12 500 per year in federal loans towards both fees and maintenance, and some private loans are also available. Most students do some paid work during their studies to make up the difference or rely on parents contributing. Parental contributions mean that students from poor families end up owing more. According to a Guardian article:

Race is a huge factor. Black students owe an average of $7400 more than white students when they graduate, the Brookings Institution found. After graduation, the debt gap continues to widen. Four years after graduation, black graduates owe an average of nearly $53 000 – nearly double that of white graduates.

Student debt looks to become one of the key issues in the 2020 US presidential election.

Pressure to cancel student fees and debt in the USA

Most of the Democratic candidates are promising to address student fees and debt. Student debt, they claim, places an unfair burden on the younger generation and makes it hard for people to buy a house, or car or other major consumer durables. This also has a dampening effect on aggregate demand.

The most radical proposal comes from Bernie Sanders. He has vowed, if elected, to abolish student fees and to cancel all undergraduate and graduate debt of all Americans. Other candidates are promising to cut fees and/or debt.

Although most politicians and commentators agree that the USA has a serious problem of student debt, there is little agreement on what, if anything, to do about it. There are already a number of ways in which student debt can be written off or reduced. For example, if you work in the public sector for more than 10 years, remaining debt will be cancelled. However, none of the existing schemes is as radical as that being proposed by many Democrats.

Criticisms of the Democrats’ plans are mainly of two types.

The first is the sheer cost. Overall debt is around $1.6tn. What is more, making student tuition free would place a huge ongoing burden on government finances. Bernie Sanders proposes introducing a financial transactions tax on stock trading. This would be similar to a Tobin tax (sometimes dubbed a ‘Robin Hood tax’) and would include a 0.5% tax on stock transactions, a 0.1% tax on bond trades and a 0.005% tax on transactions in derivatives. He argues that the public bailed out the financial sector in 2008 and that it is now the turn of the financial sector to come to the aid of students and graduates.

The other type of criticism concerns the incentive effects of the proposal. The core of the criticism is that loan forgiveness involves moral hazard.

The moral hazard of loan forgiveness

The argument is that cancelling debt, or the promise to do so, encourages people to take on more debt. Generally, moral hazard occurs when people are protected from the consequences of their actions and are thus encouraged to make riskier decisions. For example, if you are ensured against theft, you may be less careful with your belongings. As the Orange County Register article linked below states:

If the taxpayers pay the debts of everyone with outstanding student loans, how will that affect the decisions made by current students thinking about their choices for financing higher education? What’s the message? Borrow as much as you can and wait for the debt to be canceled during the next presidential primary campaign?

Not only would more students be encouraged to go to college, but they would be encouraged to apply for more costly courses if they were free.

Universities would be encouraged to exaggerate their costs to warrant higher fees charged to the government. The government (federal, state or local) would have to be very careful in auditing courses to ensure costs were genuine. Universities could end up being squeezed for finance as government may try to cut payments by claiming that courses were overpriced.

Even if fees were not abolished, cancelling debts would encourage students to take on larger debt, if that was to be cleared at some point in the future. What is more, students (or their parents) who could afford to pay, would choose to borrow the money instead.

But many countries do have free or highly subsidised higher education. Universities are given grants which are designed to reflect fair costs.

The latest UK house price index reveals that annual house price growth in the UK slowed to just 1.2 per cent in May. This is the lowest rate of growth since January 2013. This is being driven, in part, by the London market where annual house price inflation rates have now been negative for 15 consecutive months. In May the annual rate of house price inflation in London fell to -4.4 per cent, it lowest since August 2009 as the financial crisis was unfolding. However, closer inspection of the figures show that while many other parts of the country continue to experience positive rates of annual house price inflation, once general inflation is accounted for, there is widespread evidence of widespread real house price deflation.

The average UK house price in May 2019 was £229,000. As Chart 1 shows, this masks considerable differences across the UK. In England the average price was £246,000 (an annual increase of 1.0 per cent), in Scotland it was £153,000 (an increase of 2.8 per cent), in Wales £159,000 (an increase of 3.0 per cent) and in Northern Ireland it was £137,000 (an increase of 2.1 per cent). (Click here to download a PowerPoint copy of the chart.)

The London market distorts considerably the English house price figures. In London the average house price in May 2019 was £457,000 (an annual decrease of 4.4 per cent). House prices were lowest in the North East region of England at £128,000. The North East was the only other English region alongside London to witness a negative rate of annual house price inflation, with house prices falling in the year to May 2019 by 0.7 per cent.

Chart 2 allows us to see more readily the rates of house price growth. It plots the annual rates of house price inflation across London, the UK and its nations. What is readily apparent is the volatility of house price growth. This is evidence of frequent imbalances between the flows of property on to the market to sell (instructions to sell) and the number of people looking to buy (instructions to buy). An increase in instructions to buy relative to those to sell puts upwards pressure on prices whereas an increase in the relative number of instructions to sell puts downward pressure on prices. (Click here to download a PowerPoint copy of the chart.)

Despite the volatility in house prices, the longer-term trend in house prices is positive. The average annual rate of growth in house prices between January 1970 and May 2019 in the UK is 9.1 per cent. For England the figure is 9.4 per cent, for Wales 8.8 per cent, for Scotland 8.5 per cent and for Northern Ireland 8.3 per cent. In London the average rate of growth is 10.4 per cent per annum.

As Chart 3 illustrates, the longer-term growth in actual house prices cannot be fully explained by the growth in consumer prices. It shows house price values as if consumer prices, as measured by the Retail Prices Index (RPI), were fixed at their January 1987 levels. We see real increases in house prices or, expressed differently, in house prices relative to consumer prices. In real terms, UK house prices were 3.6 times higher in May 2019 compared to January 1970. For England the figure is 4.1 times, for Wales 3.1 times, for Scotland 2.9 times and for Northern Ireland 2.1 times. In London inflation-adjusted house prices were 5.7 times higher. (Click here to download a PowerPoint copy of the chart.)

The volatility in house prices continues to be evident when adjusted for changes in consumer prices. The UK’s annual rate of real house price inflation was as high as 40 per in January 1973, yet, on the other hand, in June 1975 inflation-adjusted house prices were 16 per cent lower than a year earlier. Over the period from January 1970 to May 2019, the average annual rate of real house price inflation was 3.2 per cent. Hence house prices have, on average, grown at an annual rate of consumer price inflation plus 3.2 per cent.

Chart 4 shows annual rates of real house price inflation since 2008 and, hence, from around the time the financial crisis began to unfold. The period is characterised by acute volatility and with real house prices across the UK falling at an annual rate of 16 per cent in 2009 and by as much 29 per cent in Northern Ireland. (Click here to download a PowerPoint copy of the chart.)

The UK saw a rebound in nominal and real house price growth in the period from 2013, driven by a strong surge in prices in London and the South East, and supported by government initiatives such as Help to Buy designed to help people afford to buy property. But house price growth then began to ease from early/mid 2016. Some of the easing may be partly due to any excessive fizz ebbing from the market, especially in London, and the impact on the demand for buy-to-let investments resulting from reductions in tax relief on interest payments on buy-to-let mortgages.

However, the housing market is notoriously sensitive to uncertainty, which is not surprising when you think of the size of the investment people are making when they enter the market. The uncertainty surrounding Brexit and the UK’s future trading relationships will have been a drag on demand and hence on house prices.

Chart 4 shows that by May 2019 all the UK nations were experiencing negative rates of real house price inflation, despite still experiencing positive rates of nominal house price inflation. In Wales the real annual house price inflation rate was -0.1 per cent, in Scotland -0.2 per cent, in Northern Ireland -0.9 per cent and in England -2.0 per cent. Meanwhile in London, where annual house price deflation has been evident for 15 consecutive months, real house prices in May 2019 were falling at an annual rate of 7.2 per cent.

Going forward the OBR’s Fiscal Risks Report predicts that, in the event of a no-deal, no-transition exit of the UK from the European Union, nominal UK house prices would fall by almost 10 per cent between the start of 2019 and mid-2021. This forecast is driven by the assumption that the UK would enter a year-long recession from the final quarter of 2019. It argues that property transactions and prices ‘move disproportionately’ during recessions. (See John’s blog The costs of a no-deal Brexit for a fuller discussion of the economics of a no-deal Brexit). The danger therefore is that the housing market becomes characterised by both nominal and real house price falls.
