In September 2023, the Stonegate Group, the largest pub company in the UK with around 4,500 premises, announced that it was going to start increasing the pint of beer by 20p during busy periods. There was an immediate backlash on social media with many customers calling on people to boycott Stonegate’s pubs such as the Slug & Lettuce and Yates.
This announcement is an example of dynamic pricing, where firms with market power adjust prices relatively quickly in response to changing market conditions: i.e. to changes in demand and supply.
Traditionally, prices set by firms in most retail markets have been less flexible. They may eventually adjust to changing market conditions, but this could take weeks or even months. If a product proves to be popular on a particular day or time, firms have typically left the price unchanged with the item selling out and customers facing empty shelves. If the product is unpopular, then the firm is left with unsold stock.
One business that makes extensive use of dynamic pricing is Amazon. Prices for popular items on Amazon Marketplace change every 10 minutes and can fluctuate by more than 20 per cent in just one hour.
Conditions for dynamic pricing to operate
The Amazon example helps to illustrate the conditions that must be in place for a firm to implement dynamic pricing successfully. These include:
- The capacity to collect and process large amounts of accurate real-time data on the demand for and supply of particular items i.e. the number of sales or the interest in the product.
- The ability to adjust prices in a timely manner in response to changing market conditions indicated by the data.
- Effectively communicating the potential advantages of the pricing strategy to consumers.
Consumer attitudes
The last point is an interesting one. As the Stonegate example illustrates, consumers tend to dislike dynamic pricing, especially when price rises reflect increases in demand. A previous article on this website discussed the unpopularity of dynamic pricing amongst fans in the ticket market for live musical events.
The precise reason for the increase in demand, can also have an impact on consumer attitudes. For example, following a mass shooting at a subway station in New York in April 2022, the authorities shut down the underground system. This led to a surge in demand for taxis and this was picked up by the algorithm/software used by Uber’s dynamic pricing system. Fares for Uber cars began to rise rapidly, and people started to post complaints on social media. Uber responded by disabling the dynamic pricing system and capping prices across the city. It also announced that it would refund customers who were charged higher prices after the subway system shut down.
There is a danger for businesses that if they fail to communicate the policy effectively, annoyed customers may respond by shopping elsewhere. However, if it is implemented successfully then it can help businesses to increase their revenue and may also have some advantages for consumers.
The growing popularity of dynamic pricing
It has been widely used in airline and hotel industries for many years. Robert Cross, who chairs a revenue management company predicts that ‘It will eventually be everywhere’.
More businesses in the UK appear to be using dynamic pricing. In a consumer confidence survey undertaken for Barclays in September 2023, 47 per cent of the respondents had noticed more examples of companies raising prices for goods/services in response to higher demand at peak times.
It has traditionally been more difficult for bricks-and-mortar retailers to implement dynamic pricing because of the costs of continually changing prices (so-called ‘menu costs’). However, this might change with the increasing use of electronic shelf labels.
It will be interesting to see if dynamic pricing becomes more widespread in the future or whether opposition from consumers limits its use.

When did you last think about buying a new car? If not recently, then you may be in for a surprise next time you shop around for car deals. First, you will realise that the range of hybrid cars (i.e. cars that combine conventional combustion and electric engines) has widened significantly. The days when you only had a choice of Toyota Prius and another two or three hybrids are long gone! A quick search on the web returned 10 different models (although five of them belong to the Toyota Prius family), including Chevrolet Malibu, VW Jetta and Ford Fusion. And these are only the cars that are currently available in the UK market.
But the biggest surprise of all may be the number of purely (plug-) electric cars that are available to UK buyers these days. The table below provides a summary of total registrations of light-duty plug-electric cars by model in the UK, between 2010 and June 2016.
Source: Wikipedia, “Plug-in electric vehicles in the United Kingdom”
In 2010 there were nly 138 electric vehicles in total registered in the UK. They were indeed an unusual sight at that time – and good luck to you if you had one and you happened to run out of power in the middle of a journey. In 2011 this (small) number increased sevenfold – an increase that was driven mostly by the successful introduction of Nissan Leaf (635 electric Nissans were registered in the UK that year). And since then the number of electric vehicles registered in the country has increased with spectacular speed, at an average rate of 252% per year.
There is clearly strong interest in electric vehicles – an interest likely to increase as their price becomes more competitive. However, they are still very expensive items to buy, especially when compared with their conventional fuel-engine counterparts. What makes electric cars expensive? One thing is the cost of purchasing and maintaining a battery that can deliver a reasonable range. But the cost of batteries is falling, as more and more companies realise the potential of this new market and join the R&D race. As mentioned in a special report that was published recently in the FT:
The cost of lithium-ion batteries has fallen by 75 per cent over the past eight years, measured per kilowatt hour of output. Every time battery production doubles, costs fall by another 5 per cent to 8 per cent, according to analysts at Wood Mackenzie.
There is no doubt that more research will result in more efficient batteries, and will increase the interest in electric cars not only by consumers but also by producers, who already see the opportunity of this new global market. 
Does this mean that prices will necessarily fall further? You might think so, but then you have to take into consideration the availability and cost of mining further raw materials to make these batteries (such as cobalt, which is one of the materials used in the making of lithium-ion batteries and nearly half of which is currently sourced from the Democratic Republic of Congo). This may lead to bottlenecks in the production of new battery units. In which case, the price of batteries (and, by extension, the price of electric cars) may not fall much further until some new innovation happens that changes either the material or its efficiency.
The good news is that a lot of researchers are currently looking into these questions, and innovation will do what it always does: give solutions to problems that previously appeared insurmountable. They had better be fast because, according to estimates by Wood Mackenzie, the number of electric vehicles globally is expected to rise by over 50 times – from 2 million (in 2017) to over 125 million by 2035.
How many economists does it take to charge an electric car? I guess we are going to find out!

The Competition and Markets Authority (CMA) has imposed a record fine of £84m on the American pharmaceutical manufacturing company Pfizer and of £5.2m on its UK distributor, Flynn Pharma. The CMA found that the companies charged unfair prices to the NHS for phenytoin sodium capsules, the anti-epilepsy drug.
The price was previously regulated, but Pfizer deliberately de-branded the drug in September 2012 and immediately raised the price to Flynn Pharma by between 780% and 1600%, which, in turn, raised the price to the NHS by nearly 2600%. This made the drug many times more expensive than in any other European country.
The cost to the NHS rose from around £2m per year to around £50m in 2013. Although other generic drugs are available, there would be serious health risks to patients forced to switch drugs. The NHS thus had no alternative to paying the higher price.
Pfizer claimed that the drug was loss-making before it was de-branded. However, the CMA calculated that this did not justify the size of the price increase; that the higher price enabled Pfizer to recover all these claimed losses within just two months.
The usual practice is for pharmaceutical companies to charge high prices for new drugs for a period of time to enable them to recover high research and development costs. Later, the drugs become available as generic drugs that other manufacturers can produce. The price then normally falls dramatically.
Phenytoin sodium was invented many years ago and there has been no recent innovation and no significant investment. But, unlike with many other drugs, there has been no switching by the NHS because of possible dangers to patients. This has given Pfizer and its distributor considerable market power. As the CMA states in its press release:
Epilepsy patients who are already taking phenytoin sodium capsules should not usually be switched to other products, including another manufacturer’s version of the product, due to the risk of loss of seizure control which can have serious health consequences. As a result, the NHS had no alternative to paying the increased prices for the drug.
In conclusion, the CMA found that “both companies have held a dominant position in their respective markets for the manufacture and supply of phenytoin sodium capsules and each has abused that dominant position by charging excessive and unfair prices”.

One type of market failing is the asymmetric information between producers and consumers. Advertising, branding and marketing can either help to reduce consumers’ limited information or play on ignorance to mislead consumers.
Misleading consumers is what the pharmaceutical company Reckitt Benckiser is accused of doing with its Nurofen brand of painkillers. There are very few types of painkiller – the most common three being paracetamol, ibuprofen and aspirin. These are sold cheaply in chemists as unbranded ‘generic products’. Or you can buy much more expensive branded versions of the same drugs. Many people believe that the branded versions are more effective as they are cleverly marketed.
Reckitt Benckiser has been found guilty by the Australian federal court of deceiving consumers. The company produces various varieties of Nurofen, each claiming to target a particular type of pain. But Nurofen Back Pain, Nurofen Period Pain, Nurofen Migraine Pain and Nurofen Tension Headache are in fact identical! And in many outlets, they were sold at different prices – a form of price discrimination reflecting the strength of demand by consumers for a particular type of pain relief.
And now the UK Advertising Standards Authority is investigating the company over whether its adverts for Nurofen Express are misleading by stating that the product ‘gives you faster headache relief than standard paracetamol or ibuprofen’. Also it is investigating the company’s claim that its products directly target muscles in the head. Both Nurofen Migraine Pain and Nurofen Tension Headache claim on the front of the box to provide ‘targeted rapid relief’.
The company adopts similar practices in its combined pain-killer and decongestant drugs for relieving cold symptoms. For example, its Nurofen Cold and Flu Relief, Nurofen Day and Night Cold and Flu, Nurofen Sinus and Blocked Nose and Nurofen Sinus Pain Relief all contain the same quantities of ibuprofen and the decongestant phenylephrine hydrochloride, but each claims to do something different.
So there are various issues here. The first is whether excessive profits are made by charging a price typically 3 to 4 times greater than the identical generic version of the drug; the second is whether the company deliberately misleads consumers by claiming that a particular version of the drug targets a particular type of pain; the third is whether ‘faster acting’ versions are significantly different; the fourth is whether price discrimination is being practised.

Questions
- Is price discrimination always against the consumer’s interests?

- How, do you think, does Reckitt Benckiser decide the prices it charges retailers for its pain killers and how, do you think, do retailers determine the price they charge consumers for them?
- Is it a reasonable assumption that branded products in most cases are better than own-brand or generic versions? How is behavioural theory relevant here?
- If Reckitt Benckiser were banned from using the word ‘targets’ when referring to one of its product’s effect on particular type of pain, could the company instead use the words ‘suitable for’ relieving a particular type of pain and thereby avoid misleading consumers?

- Comment on the following statement by Dr Aomesh Bhatt, the company’s medical affairs director: ‘The Nurofen specific-pain range was launched with an intention to help consumers navigate their pain relief options, particularly within the grocery environment where there is no healthcare professional to assist decision making.’
Virtually all manual toothbrushes sold in the UK are made by Oral B (Procter & Gamble), Colgate (Colgate-Palmolive) or Listerene Reach (Johnson & Johnson). This is a powerful oligopoly.
The manufacturers distribute toothbrushes primarily through large powerful retailers, such as supermarkets and Boots. It is difficult for new entrants to persuade these retailers to stock their product. What is more, with large advertising and marketing budgets, existing toothbrush manufacturers make it difficult for new brands to attract customers.
But one company has successfully entered the children’s section of the market when Boots 
agreed to stock its product. The Rockabilly Kids toothbrush has a feature likely to appeal to both children and their parents. It wobbles! With a weight in the bottom, the brush rights itself, with a wobble, when dropped or simply placed on the basin or shelf.
This clearly appeals to small kids. It also appeals to their parents who can do away with unhygienic toothbrush holders. What is more, the self-righting wobbly toothbrush, by making the whole process of teeth cleaning fun for young kids, can help them gain good habits of oral hygiene.
So just how did the manufacturer overcome the barriers to entry into this well-established oligopoly? The following article examines how.
