Real GDP depends on two things: output per hour worked and the number of hours worked. On the surface, the UK economy is currently doing relatively well, with growth in 2014 of 2.8%. After several years of poor economic growth following the financial crisis of 2007/8, growth of 2.8% represents a return to the long-run average for the 20 years prior to the crisis.
But growth since 2010 has been entirely due to an increase in hours worked. On the one hand, this is good, as it has meant an increase in employment. In this respect, the UK is doing better than other major economies. But productivity has not grown and on this front, the UK is doing worse than other countries.
The first chart shows UK output per hour worked (click here for a PowerPoint). It is based on figures released by the ONS on 1 April 2015. Average annual growth in output per hour worked was 2.3% from 2000 to 2008. Since then, productivity growth has stalled and output per hour is now lower than at the peak in 2008.
The green line projects from 2008 what output per hour would have been if its growth had remained at 2.3%. It shows that by the end of 2014 output per hour would have been nearly 18% higher if productivity growth had been maintained.
The second chart compares UK productivity growth with other countries (click here for a PowerPoint). Up to 2008, UK productivity was rising slightly faster than in the other five countries illustrated. Since then, it has performed worse than the other five countries, especially since 2011.
Productivity growth increases potential GDP. It also increases actual GDP if the productivity increase is not offset by a fall in hours worked. A rise in hours worked without a rise in productivity, however, even though it results in an increase in actual output, does not increase potential output. If real GDP growth is to be sustained over the long term, there must be an increase in productivity and not just in hours worked.
The articles below examines this poor productivity performance and looks at reasons why it has been so bad.

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.

An article in the February 2015 issue of the Economic Journal, ‘Intergenerational Wealth Mobility in England, 1858–2012: Surnames and Social Mobility’ by Gregory Clark and Neil Cummins, looks at the persistence of wealth within British families across the generations. The article shows, ‘using rare surnames to track families, that wealth is much more persistent than standard one-generation estimates would suggest. There is still a significant correlation between the wealth of families five generations apart’.
It concludes that down the generations the main determinant of wealth is inheritance, despite all efforts to improve social mobility. The intergenerational elasticity of wealth inheritance is found to be 0.70–0.75 throughout the years 1858–2012. In other words, people’s wealth on average will be between 70% and 75% of that of their parents. Thus a large proportion of each person’s wealth depends on the wealth of their parents and a relatively small amount depends on other factors. As Clark and Cummins conclude:
The implications of this model are that wealth will be surprisingly persistent in families across multiple generations. This is what allows rich rare surnames to still remain rich on average even four generations later. It also implies that wealth differences between racial, religious and ethnic groups will also be highly persistent across generations.
So it is just inherited wealth in terms of money or property that gets passed from generation to generation? Or are their other factors, such as education, social class and social contacts, that cause 
people’s wealth to depend heavily on that of their parents? Clark and Cummins consider this question.
What is the latent variable that underlies the inheritance of wealth? Evidence in other work we have done on the inheritance of education status in England suggests that families can be conceived of as having an underlying social competence, which is highly persistent across generations. This social competence generates their outcomes on all dimensions of social status but with random components on each one. In this case, social mobility between generations measured on any single aspect of status will be much greater than mobility on a more general ranking of families’ overall social status, that averages earnings, wealth, occupation, education, health and longevity.
So does this mean that attempts to create greater social mobility and greater equality are futile? The authors maintain that although it is difficult to achieve greater social mobility, income and wealth can nevertheless be redistributed through the tax and benefits system.

Questions
- What would be the implication of an intergenerational wealth elasticity (a) of 1; (b) of 0; (c) >1; (d) <0?
- For what reasons might there be a high intergenerational wealth elasticity?
- What is the likely relationship between the intergenerational distribution of wealth and the intergenerational distribution of income?
- What difficulties are there is using rare surnames as a means of establishing the intergenerational distribution of wealth?
- Discuss the advantages and disadvantages of (a) a much higher rate of inheritance tax (in the UK it’s currently 40% on the value of a person’s estate above £325,000 when they die); (b) capping the amount that can be left to any individual from an estate, with anything above this taxed at 100%; (c) capping the total amount that can be left (other than to charity), with the rest taxed at 100%.
- What measures could be adopted to increase social mobility?
- What problems would arise from using the tax and benefit system to reduce inequality? (In 2012/13 the gini coefficient of original income was 0.52 and that of both gross income (i.e. income after benefits but before tax) and post-tax-and-benefit income in the UK was 0.37: see Table 27 of The Effects of Taxes and Benefits on Household Income, 2012/13.)
Real GDP depends on two things: output per hour worked and the number of hours worked. On the surface, the UK economy is currently doing relatively well, with growth in 2014 of 2.8%. After several years of poor economic growth following the financial crisis of 2007/8, growth of 2.8% represents a return to the long-run average for the 20 years prior to the crisis.
