As we saw in the blog post The UK’s poor productivity record, the UK’s productivity, as measured by output per hour worked, has grown much slower than in other major developed countries since the financial crisis. In fact, output per hour is lower now than in 2008. In France and Germany it is around 3 per higher than in 2008; in Japan it is nearly 6% higher; in the USA it is over 8% higher; and in Ireland it is 12% higher.

The chart below shows international comparisons of labour productivity from 2000 to 2014. (Click here for a PowerPoint of the chart.)

And it is not just labour productivity that has fallen in the UK. Total factor productivity of labour and capital combined has also fallen. This reflects the fall in business investment after the financial crisis and, more recently, meeting the demand for extra output by employing more labour rather than by investing in extra capital.

In his first major speech since the election, the Chancellor of the Exchequer, George Osborne, told the CBI that the government was intent on tackling the problem of low and stagnant productivity. This would require investment in infrastructure, such as high-speed rail, better roads, superfast broadband and a new runway in the south east. It would require investment in education, training and research; it would involve cutting red tape for business; it would require making it easier for both parents in a family to work by cutting the cost of childcare. The details of the government’s policies would be made clear in the soon-to-be published Productivity Plan.

But how much difference can the government make? Are there intractable problems that will prove virtually impossible to overcome? How much, indeed, can a government do, however much it would like to? The articles explore the issues.

Questions

  1. Define (a) labour productivity; (b) capital productivity; (c) total factor productivity.
  2. Why has the UK experienced lower productivity than other developed countries?
  3. Why may the UK’s lower unemployment than other countries in the post-recession period be the direct consequence of lower productivity growth?
  4. For what reasons might it be difficult for the government to achieve a significant increase in UK productivity?
  5. How might demand-side policy negatively impact on the supply-side policies that the government might adopt to increase productivity?
  6. How might the period up to and beyond the referendum in the UK on continuing EU membership impact on productivity?
  7. How might poor productivity be tackled?

The period from the end of the Second World War until the financial crisis of 2007–8 was one of increasing globalisation. World trade rose considerably faster than world GDP. The average annual growth in world GDP from 1950 to 2007 was 4.2%; the average annual growth in world merchandise exports was 6.7%.

And there were other ways in which the world was becoming increasingly interconnected. Cross-border financial flows grew strongly, especially in the 1990s and up to 2007. In the early 1990s, global cross-border capital flows were around 4% of world annual GDP; by 2007, they had risen to over 20%. The increasing spread of multinational corporations, improvements in transport, greater international movement of labour and improved communications were all factors that contributed to a deepening of globalisation.

But have things begun to change? Have we entered into an era of ‘deglobalisation’? Certainly some indicators would suggest this. In the three years 2012–14, world exports grew more slowly than world GDP. Global cross-border financial flows remain at about one-third of their 2007 peak. Increased banking regulations are making it harder for financial institutions to engage in international speculative activities.

What is more, with political turmoil in many countries, multinational corporations are more cautious about investing in such markets. Many countries are seeking to contain immigration. Fears of global instability are encouraging many firms to look inwards. After more than 13 years, settlement of the Doha round of international trade negotiations still seems a long way off. Protectionist measures abound, often amount to giving favourable treatment to domestic firms.

The Observer article considers whether the process of increased globalisation is now dead. Or will better banking regulations ultimately encourage capital flows to grow again; and will the inexorable march of technological progress give international trade and investment a renewed boost? Will lower energy and commodity prices help to reboot the global economy? Will the ‘Great Recession’ have resulted in what turns out to be merely a blip in the continued integration of the global economy? Is it, as the Huffington Post article states, that ‘globalization has a gravitational pull that is hard to resist’? See what the articles and speech have to say and what they conclude.

  2. How does globalisation affect the distribution of income (a) between countries; (b) within countries?
  3. Why has the Doha round of trade negotiations stalled?
  4. Examine the factors that might be leading to deglobalisation.
  5. What are the implications of banking deglobalisation for the UK?
  6. Are protectionist measures always undesirable in terms of increasing global GDP?
  7. What forces of globalisation are hard to resist?

The CPI index fell by 0.1% in the 12 months to April 2015. This is partly the result of lower air and sea fares, as the upward ‘blip’ in these fares at Easter last year was not present in mid-April this year as Easter fell outside the period when the statistics are collected. What is more significant is that fuel, commodity and retail food prices have fallen over the past 12 months, and the exchange rate has risen, especially against the euro.

But how do we define what’s happened and how significant is it? It might seem highly significant as it’s the first time in 55 years that the CPI has fallen over a 12-month period. In fact, the effect is likely to be temporary, as fuel prices are now rising again and commodity prices generally are beginning to rise too. What is more, the pound seems to have peaked against the euro. Thus although aggregate demand remains relatively dampened, the main causes of falling prices and potential rises in the coming months are largely to be found on the cost side. This then brings us on to the definition of a falling CPI.

A falling CPI over a 12-month period can be defined as negative inflation. This is unambiguous. But is this ‘deflation’? The problem with the term ‘deflation’ is that it is ambiguous. On the one hand it can be defined simply as negative inflation. In that case, by definition, the UK has experienced deflation. But on the other, it is used to describe a situation of persistent falling prices as a result of declining aggregate demand.

If an economy suffers from deflation in this second sense, the problem can be very serious. Persistent falling prices are likely to discourage consumers from spending on durables (such as fridges, TVs, cars and furniture) and firms from buying capital equipment. After all, why buy an item now if, by waiting, you can get it cheaper later on? This mentality of waiting to spend leads to falling aggregate demand and hence falling output. It also leads to even lower prices. In other words deflation can get worse: a deflationary spiral.

If we define deflation in this second, much more serious sense, then the UK is not suffering deflation – merely temporary negative inflation. In fact, with prices now falling (slightly) and wages rising at around 2% per year, there should be an increase in aggregate demand, which will help to drive the recovery.

For years, the UK consumer organisation, Which?, has exposed misleading supermarket pricing practices. These include bogus price reductions, ‘cheaper’ multi-buys, smaller pack sizes and confusing special offers. Claiming that these practices are still continuing, Which? has made a super-complaint (available to designated consumer bodies) to the competition regulator, the Competition and Markets Authority (CMA).

Commenting on this action, Which? executive director, Richard Lloyd said:

“Despite Which? repeatedly exposing misleading and confusing pricing tactics, and calling for voluntary change by the retailers, these dodgy offers remain on numerous supermarket shelves. Shoppers think they’re getting a bargain but in reality it’s impossible for any consumer to know if they’re genuinely getting a fair deal.

We’re saying enough is enough and using one of the most powerful legal weapons in our armoury to act on behalf of consumers by launching a super-complaint to the regulator. We want an end to misleading pricing tactics and for all retailers to use fair pricing that people can trust.”

The CMA will consider the issues raised under the super-complaint to establish whether any of them are significantly harming the interests of consumers. It will publish a response within 90 days from the receipt of the complaint on 21 April 2015. The possible outcomes include:

recommending the quality and accessibility of information for consumers is improved
encouraging businesses in the market to self-regulate
making recommendations to government to change the legislation or public policy
taking competition or consumer enforcement action
instigating a market investigation or market study
a clean bill of health

Some 40% of groceries are sold on promotion. Supermarkets are well aware that consumers love to get a bargain and use promotions to persuade consumers to buy things they might not otherwise have done.

What is more, consumer rationality is bounded by the information and time available. People are often in a hurry when shopping; prices change frequently; people are often buying numerous low-value items; and they don’t know what competitors are charging. People may thus accept an offer as genuine and not spend time investigating whether it is so. Supermarkets know this and use all sorts of tactics to try to persuade people that they are indeed getting a bargain.

The Governor of California, Jerry Brown, has issued an executive order to cut greenhouse gas emissions 40% from 1990 levels by 2030 (a 44% cut on 2012 levels). This matches the target set by the EU. It is tougher than that of the US administration, which has set a target of reducing emissions in the range of 26 to 28 percent below 2005 levels by 2025.

The former Governor of California, Arnold Schwarzenegger, had previously set a target of reducing emissions 80% below 1990 levels by 2050. Brown’s new target can be seen as an interim step toward meeting that longer-term goal.

There are several means by which it is planned to meet the Californian targets. These include:

a focus on zero- and near-zero technologies for moving freight, continued investment in renewables including solar roofs and distributed generation, greater use of low-carbon fuels including electricity and hydrogen, stronger efforts to reduce emissions of short-lived climate pollutants (methane, black carbon and fluorinated gases), and further efforts to create liveable, walkable communities and expansion of mass transit and other alternatives to travelling by car.

Some of these will be achieved through legislation, after consultations with various stakeholders. But a crucial element in driving down emissions is the California’s carbon trading scheme. This is a cap-and-trade system, similar to the EU’s Emissions Trading Scheme.

The cap-and-trade rules came into effect on January 1, 2013 and apply to large electric power plants and large industrial plants. In 2015, they will extend to fuel distributors (including distributors of heating and transportation fuels). At that stage, the program will encompass around 360 businesses throughout California and nearly 85 percent of the state’s total greenhouse gas emissions.

Under a cap-and-trade system, companies must hold enough emission allowances to cover their emissions, and are free to buy and sell allowances on the open market. California held its first auction of greenhouse gas allowances on November 14, 2012. This marked the beginning of the first greenhouse gas cap-and-trade program in the United States since the group of nine Northeastern states in the Regional Greenhouse Gas Initiative (RGGI), a greenhouse gas cap-and-trade program for power plants, held its first auction in 2008.

Since January 2014, the Californian cap-and-trade scheme has been linked to that of Quebec in Canada and discussions are under way to link it with Ontario too. Also California is working with other west-coast states/provinces, Oregon, Washington and British Columbia, to develop a co-ordinated approach to greenhouse gas reductions

To achieve sufficient reductions in emissions, it is not enough merely to have a cap-and-trade system which, through trading, encourages an efficient reduction in emissions. It is important to set the cap tight enough to achieve the targeted reductions and to ensure that the cap is enforced.

In California, emissions allowances are distributed by a mix of free allocation and quarterly auctions. Free allocations account for around 90% of the allocations, but this percentage will decrease over time. The total allowances will decline (i.e. the cap will be tightened) by 3% per year from 2015 to 2020.

At present the system applies to electric power plants, industrial plants and fuel distributors that emit, or are responsible for emissions of, 25,000 metric tons of carbon dioxide equivalent (CO2e) per year or more. The greenhouse gases covered are the six covered by the Kyoto Protocol ((CO2, CH4, N2O, HFCs, PFCs, SF6), plus NF3 and other fluoridated greenhouse gases.
