The service sector continues to drive the UK business cycle

The latest GDP numbers from the Office for National Statistics contained in Quarterly National Accounts, Q2 2014 show the economy’s output expanded by 0.9 per cent in the second quarter. This follows on the back of a 0.7 per cent increase in output in Q1 2014. The economy’s output is now thought to be 0.7 per cent above its Q1 2008 peak. Yet, the data show very different profiles for the four principal industrial sectors. The service sector appears to be ploughing ahead while the rest (production, construction and agriculture) lag behind.

Chart 1 shows quarterly economic growth since 1980s (click here for a PowerPoint of the chart). It illustrates nicely the inherent volatility of economies – one of the threshold concepts in economics. The average quarterly rate of growth since 1980 has been 0.5 per cent. On the face of it, a quarterly growth number of 0.9 per cent would appear very robust. Of course, this has to been set in the context of the 2008/9 recession. UK output peaked in Q1 2008 (£414.424 billion at 2011 prices). The revised data now show that there followed 5 quarters of declining output (previously, data suggested the duration of the recession was 6 quarters). During this period output shrank 6 per cent (GDP at 2011 prices had fallen by Q2 2009 to £389.388 billion ).

Chart 1 highlights two earlier downturns. First, there is the recession of the early 1980s. We can see the 5-quarter recession that commenced in Q1 1980. By the end of this recession output had shrunk by 4.5 per cent. Second, there is the recession of the early 1990s which commenced in Q3 1990. Again, this recession lasted five quarters. By the time the economy had come out of recession it had shrunk 2.2 per cent.

Consider now Chart 2 (click here for a PowerPoint of the chart). It allows us to analyse more recent events by tracking how industrial output has evolved since 2006. It suggests an unbalanced recovery. From it, we observe that in Q2 2014 service-sector output was 6.5 per cent higher than in Q1 2008. However, a very different picture emerges for the other principal industrial types. Output across the production industries remains 9.7 per cent lower, 9.2 per cent lower in agriculture and 8.9 per cent lower in the construction sector.

In short, the British economy continues to struggle to rebalance its industrial base. The business cycle remains heavily dependent on the service sector.

Big Mac wages

At least once a year The Economist publishes its ‘hamburger standard’ exchange rates for currencies. It is a light-hearted attempt to see if currencies are exchanging at their purchasing-power parity rates. The test is the price at which a ‘Big Mac’ McDonald’s hamburger sells in different countries!

According to this simplified version of the purchasing-power parity theory, exchange rates should adjust so that a Big Mac costs the same in dollars everywhere (see Economics 8th edition Box 25.4).

These Big Mac exchange rates can be used to compare various prices and incomes between countries. The article linked below from The Guardian compares minimum wages between European countries in Big Mac terms.

There are 25 countries across Europe which have minimum wages. A clear pattern of minimum wage rates can be seen: although actual exchange rates understate the purchasing power of incomes in poorer European countries compared to richer ones, minimum wages, even in purchasing-power standard terms, are still higher in the richer countries.

Luxembourg’s minimum wage buys you just about three Big Macs in an hour, while most of northern Europe (and France) between 2–2.5 Big Macs. Moving south, the minimum wage nets about one Big Mac an hour. As we progress east, it begins to cost more than an hour of work on the minimum wage in order to afford a Big Mac.

Of course, there are other factors determining the dollar price of a Big Mac other than the failure of exchange rates to reflect purchasing-power parities. Nevertheless, using the Big Mac index in this way does give a useful preliminary snap shot of differences in what minimum wages can buy in different countries.

Supermarket wars: a pricing race to the bottom

In an earlier post, Elizabeth looked at oligopolistic competition between supermarkets. Although supermarkets have been accused of tacit price collusion on many occasions in the past, price competition has been growing. And recent developments show that it is likely to get a lot fiercer as the ‘big four’ try to take on the ‘deep discounters’, Aldi and Lidl.

Part of the reason for the growth in price competition has been a change in shopping behaviour. Rather than doing one big shop per week in Tesco, Sainsbury’s, Asda or Morrisons, many consumers are doing smaller shops as they seek to get more for their money. A pattern is emerging for many consumers who are getting their essentials in Aldi or Lidl, their ‘special’ items in more upmarket shops, such as Waitrose, Marks & Spencer or small high street shops (such as bakers and ethnic food shops) and getting much fewer products from the big four. Other consumers, on limited incomes, who have seen their real incomes fall as prices have risen faster than wages, are doing virtually all their shopping in the deep discounters. As the Guardian article below states:

A steely focus on price and simplicity, against a backdrop of falling living standards that has sharpened customers’ eye for a bargain, has seen the discounter grab market share from competitors and transform what we expect from our weekly shop.

The result is that the big four are seeing their market share falling, as the chart shows. (Click here for a PowerPoint of the chart.) In the past year, Tesco’s market share has fallen from 29.9% to 28.1%, Asda’s from 17.8% to 16.3%, Sainsbury’s from 16.9% to 16.2% and Morrisons’ from 11.7% to 11.0%. By contrast, Aldi’s has risen from 3.9% to 5.4% and Lidl’s from 3.1% to 4.0%, while Waitrose’s has also risen, from 4.7% to 4.9%. And it’s not just market share that has been falling for the big four. Profits have also fallen, as have share prices. Sales revenues in the four weeks to 13 September are down 1.6% on the same period a year ago; sales volumes are down 1.9%.

But can the big four take on the discounters at their own game? Morrison’s has just announced a form of price match scheme called ‘Match & More’. If a shopper finds that a comparable grocery shop is cheaper in not only Tesco, Sainsbury’s or Asda, but also in Aldi or Lidl, then ‘Match & More users will automatically get the difference back in points on their card. Shoppers also will be able to collect extra points on hundreds of featured products and fuel’. When the difference has risen to a total £5 (5000 points), the shopper will get a £5 voucher at the till. The idea is to encourage customers to stay loyal to Morrisons.

But what if Tesco, Asda and Sainsbury’s do the same? What will be the impact on their prices and profits. Will there be a race to the bottom in prices, or will they be able to keep prices higher than the deep discounters, hoping that many customers will not cash in their vouchers?

But if effectively the big four felt forced to cut their prices to match Aldi and Lidl, could they afford to do so? This depends on their comparative average costs. At first sight, it might be thought that the big four could succeed in profitably matching the discounters, thereby clawing back market share. After all, they are much bigger and it might be thought that they would benefit from greater economies of scale and hence lower costs.

But it is not as simple as this. The discounters have lower costs than the big four. Their shops are typically in areas where rents or land prices are lower; their shops are smaller; they carry many fewer lines and thus gain economies of scale on each line; they have a much higher proportion of own-brand products; products are displayed in the boxes they come in, thus saving on the staff costs of unpacking them and placing them on shelves; they buy what is cheapest and thus do not always display the same brands.

So is Morrison’s a wise strategy? Will other supermarkets be forced to follow? Is there a prisoners’ dilemma here and, if so, is there any form of collusion in which the big four can engage which is not illegal? Can the big four differentiate themselves from the discounters and the up-market supermarkets in ways that will attract back customers?

It is worrying times for the big four.

‘Better Together’ Indeed

The Scottish debate revolved around a variety of issues and one of the key factors that added weight to the ‘No’ campaign was the idea of being British. But the concept of ‘Britishness’ is not just important to those who live here. It still appears to be a key signal of quality in foreign markets and it is something which foreign consumers are willing to pay a price for.

Barclays Corporate Banking has undertaken research into eight key export markets to determine the value of ‘Britain’. One of the key factors that boost demand for a product is quality and another is the idea of a brand. As quality improves and brands become more recognized, a product’s demand curve will begin to shift to the right, thus pushing up the market price. In other words, with higher quality and brand recognition, an individual’s willingness to pay rises. One brand that foreign consumers seem willing to pay a premium to purchase are those labelled ‘Made in Britain’.

The research indicates that 31% of customers in emerging markets have been prepared to and have purchased products that are from Britain, despite the higher price. Seeing the label ‘Made in Britain’ seems to send the signal of quality and this in turn creates a higher willingness to pay. Furthermore, this willingness to pay, while still good for Scottish, English and Welsh products, is higher for ‘British’ products, perhaps another indication of the truth behind the ‘Better together’ campaign.

The increase in willingness to pay between products with seemingly no country of origin and a British country of origin is 7% and this knowledge should give a confidence boost to the British export market. It should also indicate to exporters in Wales, Scotland and England that they are better to advertise as ‘Made in Britain’ than ‘Made in Wales, Scotland or England’. The expected boost from the 8 key emerging markets is around £2bn. The following articles consider the concept of ‘Brand Britain’.

Questions

  1. Using a diagram, illustrate the effect of a product’s being a well-known brand on its equilibrium price and quantity.
  2. Why is it that the relative willingness to pay a premium for British products is higher in developing countries than in developed countries?
  3. Using the concept of marginal utility theory, explain the impact of the ‘Made in Britain’ label.
  4. The BBC News article suggests, however, that some Welsh companies have not found the brand effect to be the case. What factors might explain this?
  5. To what extent are the concepts of consumer and producer surplus relevant here?

Cloudy skies ahead?

Now here’s a gloomy article from Robert Peston. He’s been looking at investors’ views about the coming years and sees a general pessimism about the prospects for long-term economic growth. And that pessimism is becoming deeper.

It is true that both the UK and the USA have recorded reasonable growth rates in recent months and do seem, at least on the surface, to be recovering from recession. But, according to investor behaviour, they:

seem to be saying, in how they place their money, that the UK’s and USA’s current reasonably rapid growth will turn out to be a short-lived period of catch-up, following the deep recession of 2008-9.

So what is it about investor behaviour that implies a deep pessimism and are investors right to be pessimistic? The article explores these issues. It does also look at an alternative explanation that investors may merely be being cautious until a clearer picture emerges about long-term growth prospects – which may turn out to be better that many currently now predict.

The article finishes by looking at a possible solution to the problem (if you regard low or zero growth as a problem). That would be for the government to ‘throw money at investment in infrastructure – to generate both short-term growth and enhance long-term productive potential.’

Note that Elizabeth also looks at this article in her blog The end of growth in the west?.
