An oil glut

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

  1. 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.
  2. How are the price elasticities of demand and supply relevant in explaining the magnitude of oil price movements?
  3. What are oil prices likely to be in five years’ time?
  4. Using aggregate demand and supply analysis, demonstrate the effect of lower oil prices on a national economy.
  5. 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?
  6. 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”?
  7. 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.
  8. 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?

Easy or not so easyPricing?

The pricing model for low-cost airline seats seems simple. As the seats get booked, so the price rises. Thus the later you leave it to book, the more expensive it will be. But, in fact, it’s not as simple as this. Seat prices sometimes come down as the take-off date approaches. So what is the pricing model?

The general principle of raising prices as the plane fills up still applies. This enables the airline to discriminate between passengers. Holidaymakers and those with flexibility about when, and possibly where, to travel tend to have a relatively high price elasticity of demand. People who wish to travel at the last minute, such as businesspeople and those facing a family emergency, tend to have a much lower price elasticity of demand and would be prepared to pay a higher, possibly much higher, price.

With relatively high fixed costs for each flight, low-cost airlines need to fill, or virtually fill, their planes if they are to make a profit. And it’s not just about the direct revenue from ticket sales. Low-cost carriers also rely on the revenue from selling extras, such as on-board refreshments, hold luggage, hotels, car hire and travel insurance. With variable costs being tiny, the pricing model is about maximising revenue for each flight. So the fuller the plane, the better it is for the airline.

The airlines are very experienced in estimating demand over the period from a flight coming on sale and the departure date. If they get it right, then prices will indeed rise as take-off approaches. But sometimes they get it wrong. If, as time passes, a given flight is filling up too slowly, then it makes sense to be more flexible on prices, cutting them if necessary. Pricing may be easy in principle; but not always easy in practice!

Questions

  1. Does a low-cost airline always charge lower prices than a traditional scheduled airline? If not, why not?
  2. Identify the various reasons why holidaymakers may have a relatively elastic demand for a particular flight?
  3. Explain the system of ‘buckets’ of seats?
  4. Are low-cost airlines engaging in price discrimination and, if so, which type?
  5. Are there any variable costs of operating a particular flight (assuming that the flight does actually take place)?
  6. If demand for a flight becomes less elastic as the date of departure gets nearer, why might a budget airline choose to lower the price, at least for a few days?
  7. Why can Ryanair operate with lower costs than easyJet?
  8. Would it be in low-cost airlines’ interests to charge more (a) to overweight people; (b) for using the toilet?
