In recent times the notion that the financial sytem can be destabilising seems blindingly obvious. And, yet, for some time macroeconomic models of the economy tended to regard the financial system as benevolent. It served our interests. We were the masters; it was our servant. Now of course we accept that credit cycles can be destabilising. Policymakers, especially central banks, follow keenly the latest private-sector credit data. Here we look back at previous patterns in private-sector debt and crucially at what patterns are currently emerging.
First a bit of theory. The idea of credit cycles is not new. But the financial crisis of the late 2000s has helped to reignite analysis and interest. Economists are trying to gain a better understanding of the relationship between flows of credit and the state of the economy and, in particular, why might flows increase as the level of real GDP rises – why might they be endogenous variables in models of the determination of GDP. One possibility is the financial accelerator. This is the idea that as real GDP rises banks perceive lending to be less risky. After all, real incomes will tend to rise and collateral values (against which borrowing can be secured) are likely to be rising too.
Another possibility is growing exuberance as the economy grows. This has gained in popularity as an idea, with economists revisiting the work of Hyman Minsky (1919–96), an American economist. Here success breeds failure as the balance sheets of people and businesses deteriorate as they become increasingly burdened with debt. The balance sheets are said to be congested leading to a point when a deleveraging starts. A balance sheet recession then follows.
Now for the data. Consider first the stocks of debt acquired by households and private non-financial corporations from MFIs (Monetary Financial Institutions). The first chart shows debt stocks as a percentage of GDP. It illustrates nicely the phenomenon of financialisation. In essence, this is the increasing importance of MFIs to the economy. At the end of 2014, these two sectors had debt stocks outstanding equivalent to 90 per cent of GDP. In fact, this is down from a peak of 129 per cent in September 2009. (Click here for a PowerPoint of the chart.)
The growth in debt, especially in the 1990s and for much of the 2000s, was through financial innovation. In particular, the bundling of assets, such as mortgages, to form financial instruments which could then be purchased by investors helped to provide financial institutions with further funds for lending. This is the process of securitisation. Some argue that this was part of a super-cycle which works alongside the normal credit cycle, albeit over a much lengthier period. It can be argued that these cycles coincided during the 1990s and for much of the 2000s until financial distress hit. The distress was hastened by central banks raising interest rates to dampen the rising rate of inflation, partly attributable to rising global commodity prices, including oil.
Some refer to 2008 as a Minsky moment. Overstretched balance sheets needed repairing. But, the collective act of repair actually caused financial well-being to worsen as asset prices and aggregate demand fell.
The global response to the events of the financial crisis has been for policy-makers to pay more attention to the aggregate level of credit provision. The Bank of England’s Financial Policy Committee (FPC) has responsibility for monitoring and helping to ensure the soundness of the UK financial system.
Undoubtedly, the FPC will have constructed a chart similar to our second chart. (Click here for a PowerPoint of the chart). This chart suggests some caution: the need for casting a ‘Minsky eye’ on lending patterns. Over 2014, the UK household sector undertook net lending (i.e. after deducting repayments) of £30 billion. While nothing like the £100 billion or so in 2007, this does mark something of a step up. Indeed it is almost exactly double the flow in 2013. In the months ahead we will continue to monitor the credit data. You can bet that the FPC will do too!

Ever been to the cinema and found it almost empty? And then wondered why you paid the full price? Perhaps you’ve taken advantage of Orange Wednesday or only go if there’s a particularly good film on? Often it might be cheaper to wait until the film is out on DVD!
Going to the cinema can be an expensive outing. The ticket, the popcorm, a drink, ice cream – it all adds up! Orange Wednesday has recently disappeared and this will definitely have an impact on consumption of movies at your local Odeon, Vue or Showcase. The impact will be on how many seats are left empty.
However, a new app could be set to generate revenues for the cinema and provide cheaper entertainment for your everyday consumer. This new app will allow cinemas to send out alerts to people in the local area advising them that a screening will have many empty seats. What’s the incentive? Perhaps a discount, or some food. But, why would they do such a thing?
If a movie is being shown at a cinema, there will be a large fixed cost. However, what happens as each additional consumer enters the theatre? Does the cost to the cinema rise? Perhaps there is a small cost with more cleaning required, but the additional cost of actually showing the film if there 11 rather than 10 people is almost (if not equal to) zero. That is, the marginal cost of an extra user is zero. Therefore, if there is a screening with many empty seats, wouldn’t the cinema be better to offer the seats for half price. After all, if you can earn £5 from selling a ticket and the additional cost is almost zero, then it’s better to sell it for £5 than not sell it for £10! The following article and video from BBC News considers this new app and other strategies to maximise cinema usage!
Apps in pockets, bums on cinema seats BBC News, Dave Lee (27/2/15)
Questions
- What would the budget constraint look like for a cinema where a discount was offered if you purchased two cinema tickets and then received the third ticket for half price?
- Why is the marginal cost of an extra user at the cinema almost zero?
- If the MC = 0, does this mean that a cinema is a public good?
- How will this new app allow a cinema to increase total revenue and profit?
- If it is cheaper to buy a DVD rather than go to a cinema, why do people still go to the cinema?
House prices are always a good signal for the strength or direction of the economy. While there will always be certain areas that are more sought after than others and such differences will be reflected in relative house prices, the regional divide that we currently see in the UK is quite astonishing.
Prior to the financial crisis, house prices had been rising across the county, but in the year following the financial crisis, they declined by 19 per cent. It was only in 2013, when prices began to increase and, perhaps more importantly, when the variation in regional house prices began to increase significantly. In mid-2014, the UK’s annual house price inflation rate was 11.7 per cent, but the rates in London and the South East were 19.1 and 12.2 per cent, respectively. Elsewhere in the UK, the average rate was 7.9 per cent.
These regional differences have continued and figures show that the current differential between the cheapest and most expensive regional average house price is now over £350,000. In particular, data from the Land Registry shows that the average house price in London is £458,283, while in the North East, it is only £97,974.
Those people who own a house in London have benefited from such high house prices, in many cases finding that their equity in their house has grown significantly. Furthermore, any home-owners selling their house in London and moving elsewhere are benefiting from lower house prices outside London.
However, most first-time buyers looking for a house in London are being competed out of the market, finding themselves unable to gain a mortgage and deposit for the amount that they require. The opposite is, of course, happening in other parts of the country. First-time buyers are more able to enter the property market, but home-owners are finding that they have much less equity in their house.
This has also caused other problems, in particular in the labour market. Workers who are moving to jobs in London are finding the house price differentials problematic. Although wage rates are often higher in London than in other parts of the country, the house price differential is significantly bigger. This means that if someone is offered a job in London, they may find it impossible to find a house of similar size in London compared to where they had been. After all, an average family home in the North East can be purchased for under £100,000, whereas an average family home in London will cost almost £500,000.
The housing market is problematic because of particular characteristics.
Supply tends to be relatively fixed, as it can take a long time to build new houses and hence to boost supply. Furthermore, the UK has a relatively dense population, with limited available land, and so planning restrictions have to be kept quite tight, which is another reason why supply can be difficult to increase.
On the demand-side, we are seeing a change in demographics, with more single-person households; people living longer; second home purchases and many other factors. 
These things tend to push up demand and, with restricted supply, house prices rise. Furthermore, with certain areas being particularly sought after, perhaps due to greater job availability, ease of commuting, schools, etc., house price differentials can be significant.
The Conservatives, together with the other main parties, have promised to build more houses to help ease the problem, but this really is a long-run solution.
The Bank of England will undoubtedly have a role to play in the future of the housing market. The affordability of mortgages is very dependent on interest rate changes by the Bank’s Monetary Policy Committee.
Although house prices in London have recently fallen a little, the housing cost gap between living in London and other areas is unlikely to close by much as long as people continue to want to live in the capital. The following articles consider the housing market and its regional variations.

‘Employment has been strong, but productivity and real wages have been flat.’ This is one of the key observations in a new OECD report on the state of the UK economy. If real incomes for the majority of people are to be raised, then labour productivity must rise.
For many years, the UK has had a lower productivity (in terms of output per hour worked) than most other developed countries, with the exception of Japan. But from 1980 to the mid 2000s, the gap was gradually narrowing. Since then, however, the gap has been widening again. This is illustrated in Chart 1, which shows countries’ productivity relative to the UK’s (with the UK set at 100). (Click here for a PowerPoint.)
Compared with the UK, GDP per hour worked in 2013 (the latest data available) was 28% higher in France, 29% higher in Germany and 30% higher in the USA. What is more, GDP per hour worked 
and GDP per capita in the UK fell by 3.8% and 6.1% respectively after the financial crisis of 2007/8 (see the green and grey lines in Chart 2). And while both indicators began rising after 2009, they were still both below their 2007 levels in 2013. Average real wages also fell after 2007 but, unlike the other two indicators, kept on falling and by 2013 were 4% below their 2007 levels, as the red line in Chart 2 shows. (Click here for a PowerPoint.)
Although productivity and even real wages are rising again, the rate of increase is slow. If productivity is to rise, there must be investment. 
This could be in physical capital, human capital or, preferably, both. But for many years the UK has had a lower rate of investment than other countries, as Chart 3 shows. (Click here for a PowerPoint.) This chart measures investment in fixed capital as a percentage of GDP.
So how can investment be encouraged? Faster growth will encourage greater investment through the accelerator effect, but such an effect could well be short-lived as firms seek to re-equip but may be cautious about committing to increasing capacity. What is crucial here is maintaining 
high degrees of business confidence over an extended period of time.
More fundamentally, there are structural problems that need tackling. One is the poor state of infrastructure. This is a problem not just in the UK, but in many developed countries, which cut back on public and private investment in transport, communications and energy infrastructure in an attempt to reduce government deficits after the financial crisis. Another is the low level of skills of many workers. Greater investment in training and apprenticeships would help here.
Then there is the question of access to finance. Although interest rates are very low, banks are cautious about granting long-term loans to business. Since the financial crisis banks have become much more risk averse and long-term loans, by their nature, are relatively risky. Government initiatives to provide finance to private companies may help here. For example the government has just announced a Help to Grow scheme which will provide support for 500 small firms each year through the new British Business Bank, which will provide investment loans and also grants on a match funding basis for new investment.

In a post last August we looked at the rising number of workers employed on ‘zero-hours’ contracts. These are contracts where there are no guaranteed minimum hours. Such contracts give employers the flexibility to employ workers as much or as little as suits the business. Sometimes it benefits workers, who might be given the flexibility to request the hours that suit them, but usually workers simply have to take the hours on offer.
Latest figures published by the Office for National Statistics show that zero-hours contracts are on the increase. In 2014 quarter 4, 697,000 workers were recorded as being on zero-hours contracts. 
This represents 2.3% of people in employment. Ten years ago (2004, Q4) the figures were 108,000 or 0.4%: see chart. (Click here for a PowerPoint of the chart.)
Around one third of the 697,000 people on zero-hours contracts wanted more work if they could get it and most wanted it in their current job rather than having to move jobs. These people wanting more work can be classed as underemployed. They also include those not on a zero-hours contract who would like to work more if they could.
According to the ONS:
‘People on zero-hours contracts are more likely to be women, in full-time education or in young or older age groups when compared with other people in employment. On average, someone on a zero-hours contract usually works 25 hours a week.’ (See section 4 of the report for more details.)
As we saw in the earlier post, many public- and private-sector employers use such contracts, including many small and medium-sized enterprises and many well-known large companies, such as Sports Direct, Amazon, JD Wetherspoon and Cineworld. It gives them the flexibility to adjust the hours they employ people. It allows them to keep people in employment when demand is low. It also makes them more willing to take on staff when demand rises, as it removes the fear of being over-staffed if demand then falls back.
As we also saw, zero-hours contracts are not the only form of flexible working. Other examples include: ‘self-employed’ workers, contracted separately for each job they do for a company; people paid largely or wholly on commission; on-call working; part-time working, where the hours are specified in advance, but where these are periodically re-negotiated; overtime; people producing a product or service for a company (perhaps at home), where the company varies the amount paid per unit according to market conditions.
The extent of zero-hours contracts varies dramatically from one sector of the economy to another. Only 0.6% of workers in the Information, Finance and Professional sectors were on zero-hours contracts in 2014 Q4, whereas 10% in the Accommodation and Food sectors were.
The flexibility that such contracts give employers may make them more willing to keep on workers when demand is low – they can reduce workers’ hours rather than laying them off. It also may make them more willing to take on workers (or increase their hours) when demand is expanding, not having to worry about being over staffed later on.
However, many workers on such contracts find it hard to budget when their hours are not guaranteed and can vary significantly from week to week.
