The Chinese economy was, for some time, the beacon of the world economy, posting strong growth and giving a much needed boost to demand in other countries. However, the weakening Chinese economy is now causing serious concerns around the world and not least in China itself.
China’s stock market on Monday 11th January closed down 5.3%, with the Hong Kong Index down by 2.8%. These falls suggest a continuing downward trajectory this week, following the 10% decline on Chinese markets last week. Today, further falls were caused, at least in part, by uncertainty over the direction of the Chinese currency, the yuan. Volatility in the currency is expected to continue with ongoing depreciation pressures and adding to this is continuing concerns about deflation.
The barrage of bad news on key economic indicators may well mean significant intervention by Chinese authorities to try to avoid its slowest growth in 25 years. However, there are also concerns about China’s ability to manage its economic policy, given recent events. IG’s Angus Nicholson said:
“Global markets are still in the grips of China fears, and it is uncertain whether the Chinese government can do enough to reassure global investors.”
Similar sentiments were echoed by Paul Mackel, head of emerging markets FX research at HSBC:
“Different signals about foreign exchange policy have wrong-footed market participants and we are wary in believing that an immediate calmness will soon emerge.”
Perhaps key to turning this downward trend on its head, will be the Chinese consumers. With a traditionally larger saving ratio than 
many Western economies, it may be that this ‘cushion’ will give growth a boost, through the contribution of consumer spending. As we know, aggregate demand comprises consumption, investment, government spending and net exports (AD = C + I + G + X – M). Consumer spending (C) increased from 50.2% in 2014 to 58.4% in 2015, according to HIS Global Insight. A similar increase for 2016 would certainly be welcome.
As oil prices continue to fall and concerns remain over China’s weak economic data, we may well soon begin to see just how interdependent the world has become. Many economists suggest that we are now closer to the start of the next recession than we are to the end of the last one and this latest turmoil on Chinese stock markets may do little to allay the fears that the world economy may once again be heading for a crash. The following articles consider the Chinese turmoil.

Questions
- How are prices and values determined on the stock market?
- Share prices in China have been falling significantly since the start of 2016. Has it been caused by demand or supply-side factors? Use a demand and supply diagram to illustrate this.
- Why has the volatility of the Chinese currency added further downward pressure to Chinese stock markets?
- With the expected increase in consumer spending in China, how will this affect AD? Use a diagram to explain your answer and using this, outline what we might expect to happen to economic growth and unemployment in China.
- Why are there serious concerns about the weak level of inflation in China? Surely low prices are good for exports.
- Should the world economy be concerned if China’s economy does continue to slow?
- To what extent are oil prices an important factor in determining the future trajectory of the world economy?
The price of petrol is of interest to most families, occupying a key component of weekly expenditure. Over the past decade, it has fluctuated significantly, from around 85p per litre to over £1.40. More recently, prices have been around £1.03 to £1.10, depending on the brand and the location. But, will we see prices falling below that magical £1 per litre mark?
We have recently seen a 2p drop in wholesale fuel prices and it is this which has led to speculation about a further fall in prices at petrol stations to below £1. This, according to the RAC, has a ‘very good chance’ of happening.
A key determinant of petrol prices is the market price for crude oil and it is this which has been contributing towards the low petrol prices. As these prices filter through to the pumps, the RAC suggests that prices may once again come down. Furthermore, with some of the key petrol stations being operated by the big supermarkets, competition for sales and hence on prices may be fierce.
But, now let’s consider another well-informed organisation. According to the AA, the chances of petrol prices falling below £1 are ‘remote’. So, who should we believe? In fact, we can probably believe both. The market price may not fall below £1, but in the run-up to Christmas and in the start of the New Year, we may well see petrol on sale for under £1 as a means to entice shoppers or, as the AA has said, as a ‘marketing gimmick’. As you can see from the picture, Asda has dropped the price below £1 per litre in some of its petrol stations.
You might think this is a little strange, given the inelastic nature of the demand for petrol: after all, as prices of petrol rise and fall, I for one, don’t change my demand. This is also confirmed by HMRC, which reports that total petrol consumption is falling despite the low prices. But, it’s probably less about changing your total demand for petrol and more about from where you buy that total demand. For any one petrol station, the demand may be relatively elastic. It is this which may fuel a price war on petrol. The following articles consider this.

Questions
- What are they demand-side and supply-side factors which have helped to cut the price of petrol? Use a diagram to illustrate your answer.
- How much of a role has OPEC played in keeping petrol prices down in the UK?
- Why is the demand for petrol price inelastic?
- HMRC suggests that despite low prices, the demand for petrol has been falling. Does this suggest that the demand curve for petrol is upward sloping? Explain your answer.
- If the demand for petrol is falling, can this tell car companies anything about the future demand for vehicles? Which concepts are important here?
- If petrol prices do not fall to reflect falling oil prices, what does this suggest about the profit margins on petrol? Should government intervene?
The demand for oil is growing and yet the price of oil, at around $46 per barrel over the past few weeks, remains at less than half that of the period from 2011 to mid 2014. The reason is that supply has been much larger than demand. The result has been a large production surplus and a growth in oil stocks. Supply did fall somewhat in October, which reduced the surplus in 2015 Q3 below than of the record level in Q2 – but the surplus was still the second highest on record.
What is more, the modest growth in demand is forecast to slow in 2016. Supply, however, is expected to decrease through the first three quarters of 2016, before rising again at the end of 2016. The result will be a modest rise in price into 2016, to around $56 per barrel, compared with an average of just over $54 per barrel so far for 2015 (click here for a PowerPoint of the chart below).
But why does supply remain so high, given such low prices? As we saw in the post The oil industry and low oil prices, it is partly the result of increases in supply from large-scale investment in new sources of oil over the past few years, such as the fracking of shale deposits, and partly the increased output by OPEC designed to keep prices low and make new investment in shale oil unprofitable.
So why then doesn’t supply drop off rapidly? As we saw in the post, A crude indicator of the economy (Part 2), even though shale oil producers in the USA need a price of around $70 or more to make investment in new sources profitable, the marginal cost of extracting oil from existing sources is only around $10 to £20 per barrel. 
This means that shale oil production will continue until the end of the life of the wells. Given that wells typically have a life of at least three years, it could take some time for the low prices to have a significant effect on supply. According to the US Energy Information Administration’s forecasts, US crude oil production will drop next year by only just over 5%, from an average of 9.3 million barrels per day in 2015 to 8.8 million barrels per day in 2016.
In the meantime, we can expect low oil prices to continue for some time. Whilst this is bad news for oil exporters, it is good news for oil importing countries, as the lower costs will help aid recovery.

Questions
- Using demand and supply diagrams, demonstrate (a) what has been happening to oil prices in 2015 and (b) what is likely to happen to them in 2016.
- How are the price elasticities of demand and supply relevant in explaining the magnitude of oil price movements?
- What are oil prices likely to be in five years’ time?
- Using aggregate demand and supply analysis, demonstrate the effect of lower oil prices on a national economy.
- Why might the downward effect on inflation from lower oil prices act as a stimulus to the economy? Is this consistent with deflation being seen as requiring a stimulus from central banks, such as lower interest rates or quantitative easing?
- Do you agree with the statement that “Saudi Arabia is acting directly against the interests of half the cartel and is running OPEC over a cliff”?
- If the oil price is around $70 per barrel in a couple of years’ time, would it be worth oil companies investing in shale oil wells at that point? Explain why or why not.
- Distinguish between short-run and long-run shut down points. Why is the short-run shut down price likely to be lower than the long-run one?
Oil prices will remain below $60 per barrel for the foreseeable future. At least this is what is being assumed by most oil producing companies. In the more distant future, prices may rise as investment in fracking, tar sands and new wells dries up. In meantime, however, marginal costs are sufficiently low as to make it economically viable to continue extracting oil from most sources at current prices.
The low prices are partly the result of increases in supply from large-scale investment in new sources of oil over the past few years and increased output by OPEC. They are also partly the result of falling demand from China.
But are low prices all bad news for the oil industry? It depends on the sector of the industry. Extraction and exploration may be having a hard time; but downstream, the refining, petrochemicals, distribution and retail sectors are benefiting from the lower costs of crude oil. For the big integrated oil companies, such as BP, the overall effect may not be as detrimental as the profits from oil production suggest.

Obesity is on the rise, especially in children. With all the attendant health problems, concern is growing and various policies have been proposed to try to tackle the problem. One such policy is a sugar tax. This could be either a universal tax on sugar in food products or a tax just on soft drinks, many of which are very high in sugar – typically about seven teaspoons in a can or individual bottle.
Currently the issue is being considered by the UK’s Parliamentary Health Select Committee. Jamie Oliver, the TV chef and restaurateur, argued strongly before the committee in favour of a sugar tax on fizzy drinks. He has already imposed a levy on soft drinks with added sugar in his restaurants. He maintained that it was not just the higher price from a sugar tax that would deter consumption of such drinks, but it would send out an important message that too much sugar is bad for you.
Two days later, Dr Alison Tedstone appeared before the committee. She is chief nutritionist at Public Health England. PHE has been carrying out research into obesity and ways of tackling it. It has reviewed two types of evidence: experimental data on the effects of imposing higher prices on products with added sugar; and the effects of policies pursued in other countries. She stated to the committee that ‘universally all the evidence shows that the tax does decrease consumption’ and that ‘the higher the tax increase, the greater the effect’.
The government was not planning to publish the report at this stage, but under considerable pressure agreed to its publication.
The articles look at the prospects for a sugar tax, its likely effects if one were introduced and at the politics of the situation, which are likely to result in such a tax being rejected.

Questions
- What factors are driving the current high consumption of sugar?
- How is the concept of price elasticity of demand relevant to the effectiveness of imposing a sugar tax?
- What would determine the incidence of such a tax between food and drink manufacturers and consumers?
- Would such a tax be progressive, regressive or neutral? Explain.
- What other policies could be pursued to discourage the consumption of sugar? Discuss their likely effectiveness and compare them with a sugar tax.
- What externalities are involved in sugar consumption? How would you set about measuring them? Should a sugar tax be set at a rate that internalises the estimated externalities?
- Examine the objections to imposing a sugar tax.
