Tag: price elasticitiy of demand

In many countries, train fares at peak times are higher than at off-peak times. This is an example of third-degree price discrimination. Assuming that peak-time travellers generally have a lower price elasticity of demand, the policy allows train companies to increase revenue and profit.

If the sole purpose of ticket sales were to maximise profits, the policy would make sense. Assuming that higher peak-time fares were carefully set, although the number travelling would be somewhat reduced, this would be more than compensated for by the higher revenue per passenger.

But there are external benefits from train travel. Compared with travel by car, there are lower carbon emissions per person travelling. Also, train travel helps to reduce road congestion. To the extent that higher peak-time fares encourage people to travel by car instead, there will be resulting environmental and congestion externalities.

The Scottish experiment with abolishing higher peak-time fares

In October 2023, the Scottish government introduced a pilot scheme abolishing peak-time fares, so that tickets were the same price at any time of the day. The idea was to encourage people, especially commuters, to adopt more sustainable means of transport. Although the price elasticity of demand for commuting is very low, the hope was that the cross-price elasticity between cars and trains would be sufficiently high to encourage many people to switch from driving to taking the train.

One concern with scrapping peak-time fares is that trains would not have the capacity to cope with the extra passengers. Indeed, one of the arguments for higher peak-time fares is to smooth out the flow of passengers during the day, encouraging those with flexibility of when to travel to use the cheaper and less crowded off-peak trains.

This may well apply to certain parts of the UK, but in the case of Scotland it was felt that there would be the capacity to cope with the extra demand at peak time. Also, in a post-COVID world, with more people working flexibly, there was less need for many people to travel at peak times than previously.

Reinstatement of peak-time fares in Scotland

It was with some dismay, therefore, especially by commuters and environmentalists, when the Scottish government decided to end the pilot at the beginning of October 2024 and reinstate peak-time fares – in many cases at nearly double the off-peak rates. For example, the return fare between Glasgow and Edinburgh rose from £16.20 to £31.40 at peak times.

The Scottish government justified the decision by claiming that passenger numbers had risen by only 6.8%, when, to be self-financing, an increase of 10% would have been required. But this begs the question of whether it was necessary to be self-financing when the justification was partly environmental. Also, the 6.8% figure is based on a number of assumptions that could be challenged (see The Conversation article linked below). A longer pilot would have helped to clarify demand.

Other schemes

A number of countries have introduced schemes to encourage greater use of the railways or other forms of public transport. One of these is the flat fare for local journeys. Provided that this is lower than previously, it can encourage people to use public transport and leave their car at home. Also, its simplicity is also likely to be attractive to passengers. For example, in England bus fares are capped at £2. Currently, the scheme is set to run until 31 December 2024.

Another scheme is the subscription model, whereby people pay a flat fee per month (or week or year, or other time period) for train or bus travel or both. Germany, for example, has a flat-rate €49 per month ‘Deutschland-Ticket‘ (rising to €58 per month in January 2025). This ticket provides unlimited access to local and regional public transport in Germany, including trains, buses, trams, metros and ferries (but not long-distance trains). This zero marginal fare cost of a journey encourages passengers to use public transport. The only marginal costs they will face will be ancillary costs, such as getting to and from the train station or bus stop and having to travel at a specific time.

Questions

  1. Identify the arguments for and against having higher rail fares at peak times than at off-peak times
  2. Why might it be a good idea to scrap higher peak-time fares in some parts of a country but not in others?
  3. Provide a critique of the Scottish government’s arguments for reintroducing higher peak-time fares.
  4. With reference to The Conversation article, why is it difficult to determine the effect on demand of the Scottish pilot of scrapping peak-time fares?
  5. What are the arguments for and against the German scheme of having a €49 per month public transport pass for local and regional transport with no further cost per journey? Should it be extended to long-distance trains and coaches?
  6. In England there is a flat £2 single fare for buses. Would it be a good idea to make bus travel completely free?

OPEC members agreed on 30 November 2016 to reduce their total oil output by 1.2m barrels per day (b/d) from January 2017 – the first OPEC cut since 2008. The biggest cut (0.49m b/d) is to be made by Saudi Arabia.

Russia has indicated that it too might cut output – by 0.3m b/d. If it carries through with this, it will be the first deal for 15 years to include Russia. OPEC members hope that non-OPEC countries will also cut output by 0.3m b/d. There will be a meeting between OPEC and non-OPEC members on 9 December in Doha to hammer out a deal. If all this goes ahead, the total cut would represent nearly 2% of world output.

The OPEC agreement took many commentators by surprise, who had expected that Iran’s unwillingness to cut its output would prevent any deal being reached. As it turned out, Iran agreed to freeze its output at current levels.

Although some doubted that the overall deal would stick, there was general confidence that it would do so. Markets responded with a huge surge in oil prices. The price of Brent crude rose from $46.48 per barrel on 29 November to $54.25 on 2 December, a rise of nearly 17% (click here for a PowerPoint of the chart)..

The deal represented a U-turn by Saudi Arabia, which had previously pursued the policy of not cutting output, so as to keep oil prices down and drive many shale oil producers out of business (see the blog, Will there be an oil price rebound?)

But if oil prices persist above $54 for some time, many shale oil fields in the USA will become profitable again and some offshore oil fields too. At prices above $50, the supply of oil becomes relatively elastic, preventing prices from rising significantly. As The Observer article states:

It is more likely that a $60 cap will emerge as the Americans, who stand outside the 13-member OPEC grouping, unplug the spigots that have kept their shale oil fields from producing in the last year or two.

… The return to action of once-idle derricks on the Texas and Dakota plains is the result of efficiency savings that have seen large jobs losses and a more streamlined approach to drilling from the US industry, after the post-2014 price tumble rendered many operators unprofitable. Only a few years ago, many firms struggled to make a profit at $70 a barrel. Now they can be competitive at much lower prices, with many expecting $50 for West Texas Intermediate – a lighter crude that typically earns $5 a barrel less than Brent.

OPEC as a cartel is much weaker than it used to be. It produces only around 40% of global oil output. Cheating from its members and increased production from non-OPEC countries, let alone huge oil stocks after two years when production has massively exceeded consumption, are likely to combine to keep prices below $60 for the foreseeable future.

The UK Supermarket industry is intensely competitive. It’s hard to slot it directly into a specific market structure, but it has many characteristics of an oligopoly – a market dominated by a few firms with intense competition, both price and non-price.

This competititve aspect of the market structure has become even more important as trading conditions become harsher. The latest development sees Sainsbury’s announcing its price promotion – it will match certain prices offered by Tesco and Asda in a bid to attract customers from its rivals.

The supermarket industry has a history of intense price wars and we can only expect them to increase. This is certainly in the interests of customers, as we face ever decreasing prices. It’s a market in which it certainly pays to shop around and compare prices. The following articles consider the latest developments in one of the most competitive markets out there.
