In delivering his Budget on 22 November, Philip Hammond reported that the independent Office for Budget Responsibility had revised down its forecasts of growth in productivity and real GDP, and hence of earnings growth.

Today, median earnings are £23,000 per annum. This is £1500 less than the £24,500 that the median worker earned in 2008 in today’s prices. The OBR forecasts a growth in real household disposable income of just 0.35% per annum for the next four years.

With lower growth in earnings would come a lower growth in tax revenues. With his desire to cut the budget deficit and start eventually reducing government debt, this would give the government less scope for spending on infrastructure, training and other public-sector investment; less scope to support public services, such as health and education; less scope for increasing benefits and public-sector wages.

The normal measure of productivity, and the one used by the OBR, is the value of output produced per hour worked. This has hardly increased at all since the financial crisis of 2008. It now takes an average worker in the UK approximately five days to produce the same amount as it takes an average worker in Germany four days. Although other countries’ productivity growth has also slowed since the financial crisis, it has slowed more in the UK and from a lower base – and is now forecast to rebound less quickly.

For the past few years the OBR has been forecasting that productivity growth would return to the trend rate of just over 2% that the UK achieved prior to 2008. For example, the forecasts it made in June 2010 are shown by the grey line in the chart, which were based on the pre-crash trend rate of growth in productivity (click on chart to enlarge). And the forecasts it made in November 2016 are shown by the pale green line. Yet each year productivity has hardly changed at all. Today output per hour is less than 1% above its level in 2008.

Now the OBR believes that poorer productivity growth will persist. It is still forecasting an increase (the blue line in the chart) – but by 0.7 of a percentage point less than it was forecasting a year ago (the pale green line): click here for a PowerPoint of the chart.

We have assumed that productivity growth will pick up a little, but remain significantly lower than its pre-crisis trend rate throughout the next five years. On average, we have revised trend productivity growth down by 0.7 percentage points a year. It now rises from 0.9 per cent this year to 1.2 per cent in 2022. This reduces potential output in 2021-22 by 3.0 per cent. The ONS estimates that output per hour is currently 21 per cent below an extrapolation of its pre-crisis trend. By the beginning of 2023 we expect this to have risen to 27 per cent.

Why has there been such weak productivity growth?
Weak productivity growth has been caused by a mixture of factors.

Perhaps the most important is that investment as a percentage of GDP has been lower than before the financial crisis and lower than in other countries. Partly this has been caused by a lack of funding for investment as banks have sought to rebuild their capital and have cut down on riskier loans. Partly it has been caused by a lack of demand for investment, given sluggish rates of economic growth and the belief that austerity will continue.

And it is not just private investment. Public-sector investment in transport infrastructure, housing and education and training has been lower than in other countries. Indeed, the poor training record and low skill levels in the UK are main contributors to low productivity.

The fall in the pound since the Brexit vote has raised business costs and further dampened demand as incomes have been squeezed.

Another reason for low productivity growth has been that employers have responded to weak demand, not by laying off workers and thereby raising unemployment, but by retaining low-productivity workers on low wages. Another has been the survival of ‘zombie’ firms, which, by paying low wages and facing ultra-low interest rates, are able to survive competition from firms that do invest.

Why is weak productivity growth forecast to continue?
Looking forward, the nature of the Brexit deal will impact on confidence, investment, wages and growth. If the deal is bad for the UK, the OBR’s forecasts are likely to be too optimistic. As it is, uncertainty over the nature of the post-Brexit world is weighing heavily on investment as some businesses choose to wait before committing to new investment.

On the other hand, exports may rise faster as firms respond to the depreciation of the pound and this may stimulate investment, thereby boosting productivity.

Another factor is the effect of continuing tight Budgets. There was some easing of austerity in this Budget, as the Chancellor accepted a slower reduction in the deficit, but government spending will remain tight and this is likely to weigh on growth and investment and hence productivity.

But this may all be too gloomy. It is very difficult to forecast productivity growth, especially as it is hard to measure output in much of the service sector. It may be that the productivity growth forecasts will be revised up before too long. For example, the benefits from new technologies, such as AI, may flow through more quickly than anticipated. But they may flow through more slowly and the productivity forecasts may have to be revised down even further!

The UK Chancellor of the Exchequer, Philip Hammond, announced in the Budget this week that national insurance contributions (NICs) for self-employed people will rise from 9% to 11% by 2019. These are known as ‘Class 4’ NICs. The average self-employed person will pay around £240 more per year, but those on incomes over £45,000 will pay £777 more per year. Many of the people affected will be those working in the so-called ‘gig economy’. This sector has been growing rapidly in recent years and now has over 4 million people working in it.

Workers in the gig economy are self employed, but are often contracted to an employer. They are paid by the job (or ‘gig’: like musicians), rather than being paid a wage. Much of the work is temporary, although many in the gig economy, such as taxi drivers and delivery people stick with the same job. The gig economy is just one manifestation of the growing flexibility of labour markets, which have also seen a rise in temporary employment, part-time employment and zero-hour contracts.

Working in the gig economy provides a number of benefits for workers. Workers have greater flexibility in their choice of hours and many work wholly or partly from home. Many do several ‘gigs’ simultaneously, which gives variety and interest.

In terms of economic theory, this flexibility gives workers a greater opportunity to work the optimal amount of time. This optimum involves working up to the point where the marginal benefit from work, in terms of pay and enjoyment, equals the marginal cost, in terms of effort and sacrificed leisure.

For firms using people from the gig economy, it has a number of advantages. They are generally cheaper to employ, as they do not need to be paid sick pay, holiday pay or redundancy; they are not entitled to parental leave; there are no employers’ national insurance contributions to pay (which are at a rate of 13.8% for employers); the minimum wage does not apply to such workers as they are not paid a ‘wage’. Also the firm using such workers has greater flexibility in determining how much work individuals should do: it chooses the amount of service it buys in a similar way that consumers decide how much to buy.

Many of these advantages to firms are disadvantages to the workers in the gig economy. Many have little bargaining power, whereas many firms using their services do. It is not surprising then that the Chancellor’s announcement of a 2 percentage point rise in NICs for such people has met with such dismay by the people affected. They will still pay less than employed people, but they claim that this is now not enough to compensate for the lack of benefits they receive from the state or from the firms paying for their services.

Some of the workers in the gig economy can be seen as budding entrepreneurs. If you have a specialist skill, you may use working in the gig economy as the route to setting up your own business and employing other people. A self-employed plumber may set up a plumbing company; a management consultant may set up a management consultancy agency. Another criticism of the rise in Class 4 NICs is that this will discourage such budding entrepreneurs and have longer-term adverse supply-side effects on the economy.

As far as the government is concerned, there is a worry about people moving from employment to self-employment as it tends to reduce tax revenues. Not only will considerably less NIC be paid by previous employers, but the scope for tax evasion is greater in self-employment. There is thus a trade-off between the extra output and small-scale investment that self-employment might bring and the lower NIC/tax revenue for the government.

As the Chancellor of the Exchequer, Philip Hammond, delivers his first Autumn statement, both the Office for Budget Responsibility (OBR) and the National Institute for Economic and Social Research (NIESR) have published updated forecasts for government borrowing and government debt.

They show a rise in government borrowing compared with previous forecasts. The main reason for this is a likely slowdown in the rate of economic growth and hence in tax revenues, especially in 2017. Last March, the OBR forecast GDP growth of 2.2% for 2017; it has now revised this down to 1.4%.

This forecast slowdown is because of a likely decline in the growth of aggregate demand caused by a decline in investment as businesses become more cautious given the uncertainty about the UK’s relationships with the rest of the world post Brexit. There is also likely to be a slowdown in real consumer expenditure as inflation rises following the fall in the pound of around 15%.

But what might be more surprising is that the public finances are not forecast to deteriorate even further. The OBR forecasts that the deficit will increase by a total of £122bn to £216bn over the period from 2016/17 to 2020/21. The NIESR predicts that it will rise by only £50bn to £187bn – but this is before the additional infrastructure spending and other measures announced in the Autumn Statement.

One reason is looser monetary policy. Following the Brexit vote, the Bank of England cut Bank Rate from 0.5% to 0.25% and introduced further quantitative easing. This makes it cheaper to finance government borrowing. What is more, the additional holdings of bonds by the Bank mean that the Bank returns to the government much of the interest (coupon payments) that would otherwise have been paid to the private sector.

Then, depending on the nature of the UK’s post-Brexit relationships with the EU, there could be savings in contributions to the EU budget – but just how much, no-one knows at this stage.

Finally, it depends on just what effects the measures announced in the Autumn Statement will have on tax revenues and government spending. We will examine this in a separate blog.

But even though public-sector borrowing is likely to fall more slowly than before the Brexit vote, the trajectory is still downward. Indeed, the previous Chancellor, George Osborne, had set a target of achieving a public-sector surplus by 2019/20.

But, would eventually bringing the public finances into surplus be desirable? Apart from the dampening effect on aggregate demand, such a policy could lead to underinvestment in infrastructure and other public-sector capital. There is thus a strong argument for continuing to run a deficit on the public-sector capital account to fund public-sector investment – such investment will increase incomes and social wellbeing in the future. It makes sense for the government to borrow for investment, just as it makes sense for the private sector to do so.

Back in October, we looked at the growing pressure in the UK for a sugar tax. The issue of childhood obesity was considered by the Parliamentary Health Select Committee and a sugar tax, either on sugar generally, or specifically on soft drinks, was one of the proposals being considered to tackle the problem. The committee studied a report by Public Health England, which stated that:

Research studies and impact data from countries that have already taken action suggest that price increases, such as by taxation, can influence purchasing of sugar sweetened drinks and other high sugar products at least in the short-term with the effect being larger at higher levels of taxation.

In his Budget on 16 March, the Chancellor announced that a tax would be imposed on manufacturers of soft drinks from April 2018. This will be at a rate of 18p per litre on drinks containing between 5g and 8g of sugar per 100ml, such as Dr Pepper, Fanta and Sprite, and 24p per litre for drinks with more than 8g per 100ml, such as Coca-Cola, Pepsi and Red Bull.

Whilst the tax has been welcomed by health campaigners, there are various questions about (a) how effective it is likely to be in reducing childhood obesity; (b) whether it will be enough or whether other measures will be needed; and (c) whether it is likely to raise the £520m in 2018/19, falling to £455m by 2020/21, as predicted by the Treasury: money the government will use for promoting school sport and breakfast clubs.

These questions are all linked. If demand for such drinks is relatively inelastic, the drinks manufacturers will find it easier to pass the tax on to consumers and the government will raise more revenue. However, it will be less effective in cutting sugar consumption and hence in tackling obesity. In other words, there is a trade off between raising revenue and cutting consumption.

This incidence of tax is not easy to predict. Part of the reason is that much of the market is a bilateral oligopoly, with giant drinks manufacturers selling to giant supermarket chains. In such circumstances, the degree to which the tax can be passed on depends on the bargaining strength and skill of both sides. Will the supermarkets be able to put pressure on the manufacturers to absorb the tax themselves and not pass it on in the wholesale price? Or will the demand be such, especially for major brands such as Coca-Cola, that the supermarkets will be willing to accept a higher price from the manufacturers and then pass it on to the consumer?

Then there is the question of the response of the manufacturers. How easy will it be for them to reformulate their drinks to reduce sugar content and yet still retain sales? For example, can they produce a product which tastes like a high sugar drink, but really contains a mix between sugar and artificial sweeteners – effectively a hybrid between a ‘normal’ and a low-cal version? How likely are they to reduce the size of cans, say from 330ml to 300ml, to avoid raising prices?

The success of the tax on soft drinks in cutting sugar consumption depends on whether it is backed up by other policies. The most obvious of these would be to impose a tax on sugar in other products, including cakes, biscuits, low-fat yoghurts, breakfast cereals and desserts, and also many savoury products, such as tinned soups, ready meals and sauces. But there are other policies too. The Public Health England report recommended a national programme to educate people on sugar in foods; reducing price promotions of sugary food and drink; removing confectionery or other sugary foods from end of aisles and till points in supermarkets; setting broader and deeper controls on advertising of high-sugar foods and drinks to children; and reducing the sugar content of the foods we buy through reformulation and portion size reduction.

During the 1970s, commentators often referred to the ‘political business cycle’. As William Nordhaus stated in a 1989 paper. “The theory of the political business cycle, which analyzes the interaction of political and economic systems, arose from the obvious facts of life that voters care about the economy while politicians care about power.”

In the past, politicians would use fiscal, and sometimes monetary, policies to manipulate aggregate demand so that the economy was growing strongly at the time of the next election. This often meant doing unpopular things in the first couple of years of office to allow for popular things, such as tax cuts and increased government transfers, as the next election approached. This tended to align the business cycle with the election cycle. The economy would slow in the early years of a parliament and expand rapidly towards the end.

To some extent, this has been the approach since 2010 of first the Coalition and now the Conservative governments. Cuts to government expenditure were made ‘in order to clear up the mess left by the previous government’. At the time it was hoped that, by the next election, the economy would be growing strongly again.

But in adopting a fiscal mandate, the current government could be doing the reverse of previous governments. George Osborne has set the target of a budget surplus by the final year of this parliament (2019–20) and has staked his reputation on achieving it.

The problem, as we saw in the blog, Hitting – or missing – the government’s self-imposed fiscal targets is that growth in the economy has slowed and this makes it more difficult to achieve the target of a budget surplus by 2019–20. Given that achieving this target is seen to be more important for his reputation for ‘sound management’ of the public finances than that the economy should be rapidly growing, it is likely that the Chancellor will be dampening aggregate demand in the run-up to the next election. Indeed, in the latest Budget, he announced that specific measures would be taken in 2019–20 to meet the target, including a further £3.5 billion of savings from departmental spending in 2019–20. In the meantime, however, taxes would be cut (such as increasing personal allowances and cutting business rates) and government spending in certain areas would be increased. As the OBR states:

Despite a weaker outlook for the economy and tax revenues, the Chancellor has announced a net tax cut and new spending commitments. But he remains on course for a £10 billion surplus in 2019–20, by rescheduling capital investment, promising other cuts in public services spending and shifting a one-off boost to corporation tax receipts into that year.

But many commentators have doubted that this will be enough to bring a surplus. Indeed Paul Johnson, Director of the Institute for Fiscal Studies, stated on BBC Radio 4’s Today Programme said that “there’s only about a 50:50 shot that he’s going to get there. If things change again, if the OBR downgrades its forecasts again, I don’t think he will be able to get away with anything like this. I think he will be forced to put some proper tax increases in or possibly find yet further proper spending cuts”.

If that is the case, he will be further dampening the economy as the next election approaches. In other words, the government may be doing the reverse of what governments did in the past. Instead of boosting the economy to increase growth at election time, the government may feel forced to make further cuts in government expenditure and/or to raise taxes to meet the fiscal target of a budget surplus.
