A big expenditure for many households is petrol. The price of petrol is affected by various factors, but the key determinant is what happens in the oil market. When oil prices rise, this pushes up the price of petrol at the pumps. But, when they fall, do petrol prices also fall? That is the question the government is asking.

The price of oil is a key cost of production for companies providing petrol and so when oil prices rise, it shifts the supply curve up to the left and hence prices begin to increase. We also see supply issues developing with political turmoil, fears of war and disruption and they have a similar effect. As such, it is unsurprising that petrol prices rise with concern of supply and rising costs. But, what happens when the opposite occurs? Oil prices have fallen significantly: by a quarter. Yet, prices at the pump have fallen by around 6%. This has caused anger amongst customers and the government is now urging petrol retailers to pass their cost savings from a lower price of oil onto customers. Danny Alexander, Chief Secretary to the Treasury said:

“I believe it’s called the rocket-and-feather effect. The public have a suspicion that when the price of oil rises, pump prices go up like a rocket. But when the price of oil falls, pump prices drift down like a feather … This has been investigated before and no conclusive evidence was found. But even if there were a suspicion it could be true this time it would be an outrage.”

However, critics suggest that tax policy is partly to blame as 63% of the cost of petrol is in the form taxation through fuel duty and VAT. Therefore even if oil prices do fall, the bulk of the price we pay at the pumps is made up of tax revenue for the government. Professor Stephen Glaister, director of the RAC Foundation said:

“It’s a simple story. Before tax we have just about the cheapest petrol and diesel in Europe. After tax we have just about the most expensive … It’s right to keep the pressure on fuel retailers but if drivers want to know what’s behind the high pump prices of recent years all they have to do is follow the trail back to the Treasury … if ministers are serious about reducing fuel prices further then they should cut duty further.”

However, even taking out the fuel duty and VAT, Arthur Renshaw, an analyst at Experian has said that the actual price of petrol has fallen by 21% since last year. Still, a much bigger decrease than we have seen at the pumps. One further reason for this may be the fact that dollars is the currency in which oil is traded. The pound has been relatively weak, falling by almost 7% over the past few months and hence even though the price of oil has fallen, the effect on UK consumers has been less pronounced.

The big supermarkets have responded to government calls to cut petrol prices, but how much of this cut was influenced by the government and how much was influenced by the actions of the other supermarkets is another story. A typical oligopoly, where interdependence is key, price wars are a constant feature, so even if one supermarket cut petrol prices, this would force others to respond in kind. If such price wars continue, further price cuts may emerge. Furthermore, with oil production still at such high levels, this market may continue to put downward pressure on petrol prices. Certainly good news for consumers – we now just have to wait to see how long it lasts, with key oil producing countries, such as Russia taking a big hit. The following articles consider this story.

Questions

  1. Using a supply and demand diagram, illustrate the impact that a fall in the price of oil should have on the price of petrol.
  2. What is the impact of a tax on petrol?
  3. Why is petrol a market that is so heavily taxed? You should think about the incidence of taxation in your answer.
  4. Why does the strength of the pound have an impact on petrol prices in the UK and how much of the oil price is passed onto customers at the pumps?
  5. Does the structure of the supermarket industry help customers when it comes to the price of petrol? Explain your answer.

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.

The expansion of the BRIC economies has both advantages and disadvantages for Western countries. Their consistently high growth rates have created a much wider market place for Western firms and a much needed additional source of consumer demand, especially in times of recession. Countries such as China have had double digit growth rates, with others like India experiencing growth rates of just under 10%. But are these impressive growth rates now beginning to fall?

For the last 2 years, the growth rate in the Indian economy has been sub-5%, with growth in the 2013-14 financial year at 4.7%. Though some sectors, including agriculture have experienced buoyant growth, it is other sectors that have been holding this economy back. Manufacturing contracted at an annualised rate of 1.4% over the quarter, while mining contracted by 0.4%. With a growth rate of just under 5%, one might think that this was good – after all many Western economies have only recently entered positive growth. However, the Indian economy has a rapidly growing population and it is estimated that 10 million additional jobs each year must be created. It is this figure that requires such a high growth rate – estimated at around 8%. Thus, the sub-5% growth recorded for 2 years is insufficient to sustain the required job creation.

There are many factors that appear to be holding growth back. High inflation has been a problem for some years and the Indian currency has been relatively weak and volatile. Together, these issues have created an environment of uncertainty and if there’s one thing that investors don’t like, it’s uncertainty. This has therefore led to a lack of investment in the economy, which is a key component of aggregate demand and hence a key source of economic growth. Furthermore, interest rates rose last year, thereby pushing up the cost of borrowing and the rate of credit growth has also slowed. These factors collectively have led to lower foreign investment, domestic investment and spending, which have all contributed towards more subdued growth than in the past. Glenn Levine, a senior economist at Moody’s said:

India’s economy continues to grow well below potential as a combination of supply‐side constraints and the adverse effects of an underperforming government weigh on capital expenditure and hiring … It will be a while before the Indian economy is expanding above 6% again.

However, many economists remain optimistic about the prospects of Asia’s third-largest economy. Inflation appears to be under control and the currency has gained strength. Many believe that more investment supporting government policies will be the kick start the economy needs and this will in turn encourage firms to begin investment. It may be the new leader of this country, Narendra Modo, that will jump start the economy. The Prime Minister is expected to back policies to stimulate growth, who will direct more spending at infrastructure, simplify taxes and introduce policies to attract foreign investment. Adi Godrej, Chairman of the Godrej group said:

As soon as investors see the first signals of growth-supportive policies, you will see a definite turnaround on the ground.

The coming months will be crucial in determining how quickly the Indian economy is likely to see a return to near double digit growth. The new government has indeed promised policies to boost the economy, but the annual budget will confirm whether this promise is likely to be kept. Given the dependence of Indian jobs on a fast growth rate and the dependence of the Western world on the continued growth of the BRICs in creating a wider market for our exports, the fortunes of India are extremely important.

Globalisation has led to an increasingly interdependent world, with companies based in one country often dependent on a market abroad. In recent years, it is the rapid growth of countries like China that has led to growth in the size of the markets for many products. With incomes rising in emerging countries, demand for many products has been growing, but in the past year, the trend for Prada has ended and seems to be reversing.

As the market in China matures and growth of demand in Europe slows, Prada has seen its shares fall by the largest margin since June last year.

Prada is a well-known luxury brand. The products it sells are relatively expensive and hence its products are likely to have an income elasticity of demand well above +1. With changes in China and Europe, Prada expects its growth in sales to January 2015 will be ‘low single-digit’ – less than the 7% figure recorded for the last financial year.

This lower growth in same-store sales is likely to continue the following year as well. Add on to this the lower-than-expected profits, which missed analysts’ forecasts, and you have a prime example of a brand that is suffering because of its customer base and the economic times.

Prada isn’t alone in suffering from economic conditions and, relative to its European counterparts, is expected to have higher growth in sales and profits in the next 12 months – at 11.5% and 14.8% respectively. This is according to a survey by Thomson Reuters.

Prada has exploited high demand by Chinese consumers, but has recently been affected by the strength of the euro. A strong euro means that the Italian-based Prada is struggling with exports, which only adds to its problems. As economic growth picks up in China and as other emerging economies begin to experience more rapid economic growth, the fortunes of this luxury-retailer may change once more. However, with volatile economic times still around in many countries, the future of many retailers selling high-end products to higher income customers will remain uncertain.
