On Saturday 31 August, tickets for the much-heralded Oasis reunion tour went on sale through the official retailer, Ticketmaster. When the company sells tickets, the acts or their promoters can choose whether to use a static pricing system, where each type of ticket is sold at a set price until they have all been sold. Or they can use a dynamic pricing system (‘in-demand’ or ‘platinum’ tickets, as Ticketmaster calls them), where there is a starting price quoted, but where prices then rise according to demand. The higher the demand, the more the price is driven up. Acts or their promoters have the option of choosing an upper limit to the price.

Dynamic pricing

The Oasis tickets were sold under the dynamic pricing system, a system previously used for Harry Styles, Bruce Springsteen, Coldplay and Blackpink concerts, but one rejected by Taylor Swift for her recent Eras tour. Standing tickets for the Oasis concert with a face value of around £135 were quickly being sold for over £350. There were long online queues, with the prices rising as people slowly moved up the queue. When they reached the front, they had to decide quickly whether to pay the much higher price. Some people later suffered from buyer’s remorse, when they realised that in the pressure of the moment, they had paid more than they could afford.

Dynamic pricing is when prices change with market conditions: rising at times when demand exceeds supply and falling when supply exceeds demand. It is sometimes referred to as ‘surge pricing’ to reflect situations when price surges in times of excess demand.

Dynamic pricing is a form of price discrimination. It is an imperfect form of first-degree price discrimination, which is defined as people being charged the maximum price they are willing to pay for a product. Pricing in an eBay auction comes close to first-degree price discrimination. With dynamic pricing in the ticket market, some people may indeed pay the maximum, but others earlier in the queue will be lucky and pay less than their maximum.

Ticketmaster justifies the system of dynamic pricing, saying that it gives ‘fans fair and safe access to the tickets, while enabling artists and other people involved in staging live events to price tickets closer to their true market value’. The company argues that if the price is below the market value, a secondary market will then drive ticket prices up. Ticket touts will purchase large amounts of tickets, often using bots to access the official site and then resell them at highly inflated prices on sites such as Viagogo and Stubhub, where ticket prices for popular acts can sell for well over £1000. The day after Oasis tickets went on sale, Viagogo had seats priced at up to £26 000 each!

Oasis and Ticketmaster have tried to stamp out the unofficial secondary market by stating that only tickets bought through the official retailers (Ticketmaster, Gigsandtours and SeeTickets) will be valid. If fans want to resell a ticket – perhaps because they find they can no longer go – they can resell them on the official secondary market though Ticketmaster’s Fan-to-Fan site or Twickets. These official secondary sites allow holders of unwanted tickets to sell them for anything up to the original face value, but no more. Buyers pay a 12% handling fee. It remains to be seen whether this can be enforced with genuine tickets resold on the secondary market.

Examples of dynamic pricing

Dynamic pricing is not a new pricing strategy. It has been used for many years in the transport, e-commerce and hospitality sectors. Airlines, for example, have a pricing model whereby as a flight fills up, so the prices of the seats rise. If you book a seat on a budget airline a long time in advance, you may be able to get it at a very low price. If, on the other hand, you want a seat at the last minute, you may well have to pay a very high price. The price reflects the strength of demand and its price elasticity. The business traveller who needs to travel the next day for a meeting will have a very low price sensitivity and may well be prepared to pay a very high price indeed. Airlines also learn from past behaviour and so some popular routes will start at a higher price. A similar system of dynamic pricing is used with advance train tickets, with the price rising as trains get booked up.

The dynamic pricing system used by airlines and train companies is similar, but not identical, to first-degree price discrimination. The figure below illustrates first-degree price discrimination by showing a company setting the price for a particular product.

Assume initially that it sets a single profit-maximising price. This would be a price of P1, at an output of Q1, where marginal revenue (MR) equals marginal cost (MC). (We assume for simplicity that average and marginal costs are constant.) Total profit will be area 1: i.e. the blue area ((P1 AC) × Q1). Area 2 represents consumer surplus, with all those consumers who would have been prepared to pay a price above P1, only having to pay P1.

Now assume that the firm uses first-degree price discrimination, selling each unit of the product at the maximum price each consumer is willing to pay. Starting with the consumer only willing to pay a price of P2, the price will go on rising up along the demand with each additional consumer being charged a higher price up to the price where the demand curve meets the vertical axis. In such a case, the firm’s profit would be not just the blue area, but also the green areas 2 and 3. Note that there is no consumer surplus as area 2 is now part of the additional profit to the firm.

Although dynamic pricing by airlines is similar to this model of first-degree price discrimination, in practice some people will be paying less than they would be willing to pay and the price goes up in stages, not continuously with each new sale of a ticket. Thus, compared with a fixed price per seat, the additional profit will be less than areas 2 + 3, but total profit will still be considerably greater than area 1 alone. Note also that there is a maximum quantity of seats (Qmax), represented by a full flight. The airline would hope that demand and its pricing model are such that Qmax is less than Q2.

Dynamic pricing also applies in the hospitality sector, as hotels raise the prices for rooms according to demand, with prices at peak times often being considerably higher than off-season prices. Rather then pre-setting prices for particular seasons, dates or weekends/weekdays, many hotels, especially chains and booking agents, adjust prices dynamically as demand changes. Airbnb offers property owners what it calls ‘Smart Pricing’, where nightly prices change automatically with demand.

Another example is Uber, which uses dynamic pricing to balance demand and supply location by location. In times of peak demand on any route, the company’s algorithm will raise the price. This will encourage people to delay travelling if they can or use alternative means of transport. It will also encourage more Uber drivers to come to that area. In times of low demand, the price will fall. This will encourage more people to use the service (rather than regular taxis or buses) and discourage drivers from working in that area.

Where dynamic pricing varies with the time or date when the purchase is made, it is sometimes referred to as inter-temporal pricing. It is a form of second-degree price discrimination, which is where a firm offers consumers a range of different pricing options for the same or similar products.

Another example of dynamic pricing, which is closer to first-degree price discrimination is the use of sophisticated algorithms and AI by Amazon, allowing it to update the prices of millions of products many times a day according to market conditions. Another is eBay auctions, where the price rises as the end date is reached, according to the willingness to pay of the bidders.

Attitudes to dynamic pricing

Consumers have grown accustomed to dynamic pricing in many industries. People generally accept the pricing model of budget airlines, for example. What makes it acceptable is that most people feel that they can take advantage of early low-priced seats and can compare the current prices on different flights and airlines when making their travel plans. Pricing is transparent. With the Oasis concert, however, there wasn’t the same degree of price transparency. Many people were surprised and dismayed to find that when they got to the front of the online queue, the price had risen dramatically.

People are familiar of dynamic pricing in the context of price cuts to shift unsold stock. Supermarkets putting stickers on products saying ‘reduced for quick sale’ is an example. Another is seasonal sales. What is less acceptable to many consumers is firms putting up prices when demand is high. They see it a profiteering. Many supermarkets are introducing electronic shelf labels (ESLs), where prices can be changed remotely as demand changes. Consumers may react badly to this if they see the prices going up. The supermarket, however, may find it a very convenient way of reducing prices to shift stock – something consumers are hardly likely to complain about.

Returning to the Oasis tour, the UK government responded to the outrage of fans as ticket prices soared. Culture Secretary, Lisa Nandy, announced that the government will investigate how surge pricing for concert tickets is used by official retailers, such as Ticketmaster. This will be part of a planned review of ticket sales that seeks to establish a fairer and more transparent system of pricing.

The problem is that, with some fans being prepared to pay very high prices indeed to see particular acts and with demand considerably exceeding supply at prices that fans would consider reasonable, some way needs to be found of rationing demand. If it is not price, then it will inevitably involve some form of queuing or rationing system, with the danger that this encourages touts and vastly inflated prices on the secondary market.

Perhaps a lesson can be drawn from the Glastonbury Festival, where prices are fixed, people queue online and where security systems are in place to prevent secondary sales by ticket touts. The 2024 price was set at £355 + a £5 booking fee and purchasers were required to register with personal details and a photo, which was checked on admission.

Update

On 5 September, the CMA announced that it was launching an investigation into Ticketmaster over the Oasis concert sales. Its concerns centred on ‘whether buyers were given clear and timely information, and whether consumer protection law was breached’. This followed complaints by fans that (i) they were not given clear and timely information beforehand that the tickets involved dynamic pricing and warned about the possible prices they might have to pay and (ii) on reaching the front of the queue they were put under pressure to buy tickets within a short period of time.

Meanwhile, band member stated that they were unaware that dynamic pricing would be used and that the decision to use the system was made by their management.

A number of famous Business Schools in the UK and US such as MIT Sloan, NYU Stern and Imperial College have launched new programmes in business analytics. These courses have been nicknamed ‘Big Data finishing school’. Why might qualifications in this area be highly valued by firms?

Employees who have the skills to collect and process Big Data might help firms to successfully implement a pricing strategy that approaches first-degree price discrimination.

First-degree price discrimination is where the seller of a product is able to charge each consumer the maximum price he or she is prepared to pay for each unit of the product. Successfully implementing this type of pricing strategy could enable a firm to make more revenue. It might also lead to an increase in economic efficiency. However, the strategy might be opposed on equity grounds.

In reality, perfect price discrimination is more of a theoretical benchmark than a viable pricing strategy. Discovering the maximum amount each of its customers is willing to pay is an impossible task for a firm.

It may be possible for some sellers to implement a person-specific pricing strategy that approaches first-degree price discrimination. Firms may not be able to charge each customer the maximum amount they are willing to pay but they may be able to charge different prices that reflect customers’ different valuations of the product.

How could a firm go about predicting how much each of its customers is willing to pay? Traditionally smaller sellers might try to ‘size up’ a customer through individual observation and negotiation. The clothes people wear, the cars they drive and their ethnicity/nationality might indicate something about their income. Second-hand car dealers and stall-holders often haggle with customers in an attempt to personalise pricing. The starting point of these negotiations will often be influenced by the visual observations made by the seller.

The problem with this approach is that observation and negotiation is a time-consuming process. The extra costs involved might be greater than the extra revenue generated. This might be especially true for firms that sell a large volume of products. Just imagine how long it would take to shop at a supermarket if each customer had to haggle with a member of staff over each item in their supermarket trolley!! There is also the problem of designing compensation contracts for sales staff that provide appropriate incentives.

However the rise of e-commerce may lead to a very different trading environment. Whenever people use their smart phones, laptops and tablets to purchase goods, they are providing huge amounts of information (perhaps unconsciously) to the seller. This is known as Big Data. If this information can be effectively collected and processed then it could be used by the seller to predict different customers’ willingness to pay.

Some of this Big Data provides information similar to that observed by sellers in traditional off-line transactions. However, instead of visual clues observed by a salesperson, the firm is able to collect and process far greater quantities of information from the devices that people use.

For example, the Internet Protocol (IP) address could be used to identify the geographical location of the customer: i.e. do they live in a relatively affluent or socially deprived area? The operating system and browser might also indicate something about a buyer’s income and willingness to pay. The travel website, Orbitz, found that Apple users were 40 per cent more likely to book four or five star hotel rooms than customers who used Windows.

Perhaps the most controversial element to Big Data is the large amount of individual-level information that exists about the behaviour of customers. In particular, browsing histories can be used to find out (a) what types of goods people have viewed (b) how long they typically spend on-line and (c) their previous purchase history. This behavioural information might accurately predict price sensitivity and was never available in off-line transactions.

Interestingly, there has been very little evidence to date that firms are implementing personalised pricing on the internet. One possible explanation is that effective techniques to process the mass of available information have not been fully developed. This would help to explain the growth in business analytics courses offered by universities. PricewaterhouseCoopers recently announced its aim to recruit one thousand more data scientists over the next two years.

Another possible explanation is that firms fear a backlash from customers who are deeply opposed to this type of pricing. In a widely cited survey of consumers, 91% of the respondents believed that first-degree price discrimination was unfair.

The Scottish debate revolved around a variety of issues and one of the key factors that added weight to the ‘No’ campaign was the idea of being British. But the concept of ‘Britishness’ is not just important to those who live here. It still appears to be a key signal of quality in foreign markets and it is something which foreign consumers are willing to pay a price for.

Barclays Corporate Banking has undertaken research into eight key export markets to determine the value of ‘Britain’. One of the key factors that boost demand for a product is quality and another is the idea of a brand. As quality improves and brands become more recognized, a product’s demand curve will begin to shift to the right, thus pushing up the market price. In other words, with higher quality and brand recognition, an individual’s willingness to pay rises. One brand that foreign consumers seem willing to pay a premium to purchase are those labelled ‘Made in Britain’.

The research indicates that 31% of customers in emerging markets have been prepared to and have purchased products that are from Britain, despite the higher price. Seeing the label ‘Made in Britain’ seems to send the signal of quality and this in turn creates a higher willingness to pay. Furthermore, this willingness to pay, while still good for Scottish, English and Welsh products, is higher for ‘British’ products, perhaps another indication of the truth behind the ‘Better together’ campaign.

The increase in willingness to pay between products with seemingly no country of origin and a British country of origin is 7% and this knowledge should give a confidence boost to the British export market. It should also indicate to exporters in Wales, Scotland and England that they are better to advertise as ‘Made in Britain’ than ‘Made in Wales, Scotland or England’. The expected boost from the 8 key emerging markets is around £2bn. The following articles consider the concept of ‘Brand Britain’.

Merlin Entertainments PLC is one of the largest operator of visitor attractions in the world and owns over a third of the most popular theme parks in Europe. It runs the four most visited parks in England – Alton Towers, Legoland Windsor, Thorpe Park and Chessington World of Adventures as well as the most popular theme park in Italy – Gardaland. Alton Towers alone had 2.5 million visitors in 2013. Anybody thinking of going to one of these attractions is faced with a wide range of different entry fees .

Theme parks and tourist attractions have market power so their owners have to make some interesting pricing decisions. They have to tackle the same dilemma that confronts any seller that faces a downward sloping demand curve for its goods/services.

One option for the firm would be to increase the entry fee. This would produce higher profits per visitor as some of the surplus from the transaction previously enjoyed by the consumer will be extracted by the seller and converted into producer surplus. Unfortunately for the business the higher price, all other things equal, will also result in fewer visitors. Some people will be deterred from visiting because of the higher price and the seller will lose out on potential revenue.

An alternative strategy would be for the theme park to reduce its entry fee. All other things equal, this will increase the number of visitors. However, it would also mean that the profit per customer would fall. The frustrating issue for the seller is that some of its customers, who would still have visited the attraction at the higher price, are now able to get a better deal.

This dilemma exists if the seller has to charge all of its different customers the same entry fee. If it could charge a higher entry fee to those customers who would be willing to pay more and a lower entry fee to those who would be willing to pay less then it could make more money. Extra revenue could be obtained from those additional sales that take place at the lower price while more consumer surplus could be extracted from those still paying the higher price.

Is it possible for a firm to charge different prices to different customers for the same or a similar good or service? Table 1 below shows the entry fees for Warwick Castle, another tourist attraction owned by Merlin Entertainments PLC.

It can immediately be seen from this table that some groups of customers pay a different entry fee from others. For example adults have to pay £24 to enter on the day while people aged 60 and over pay a lower price £16.80. The entry fee for children aged between 4 and 11 is £21.00 while those aged 3 and under go for free. Students aged 16-18 can gain entry for a price of £13.50 if they can provide valid ID and purchase the tickets from the visitbritainshop website.

In this example, the company has allocated people into different categories by age (i.e. senior, adult, student, older children and younger children) and has set the entry fee that customers in each group have to pay.

The table also shows that if customers purchase on- line then they can get the tickets more cheaply. The entry fee for each category is 25% lower if the ticket is booked seven days in advance i.e. the prices shown in the last column in the table. If the booking is made between 2-6 days in advance then the discount is only 10% i.e. an adult ticket would cost £21.60. The on-line discounts are open to everyone. People are given the choice to either book on-line in advance or pay on the day. This is different from a situation where you are placed into a category by the firm. For example the customer cannot choose whether they are over 60!

If people are prepared to spend more time searching on the internet then other cheaper prices can also be obtained. Once again these offers are open to anyone willing to spend the time and effort in order to find them.

All the ticket prices above give people access to exactly the same attractions on the day. They do not give the visitor access to two of the attractions at the castle – the Dragon Tower and Castle Dungeon. Entry to the Dragon Tower would cost an adult on the day an extra £1.80 while entry to the Castle Dungeon would cost an extra £5.40.

A remarkable event took place in Venezuela on Friday 8th November. Soldiers, on the orders of the president, temporarily occupied a chain of shops run by a leading electrical retailer called Dakar. The shops were forced to cut the prices of their electrical appliances and five managers were arrested and accused of ‘hiking up’ prices.

Unsurprisingly, news of these lower prices spread very quickly and long queues rapidly appeared outside the stores as people hoped to buy plasma televisions, fridges and washing machines at bargain prices. On Sunday 9th November, the president, Nicolas Maduro, gave a televised address in which he condemned the owners of the stores and announced that he was going to ask the National Assembly to grant him extra powers so that he could extend price controls to all consumer goods. He stated that he would next turn his attention to stores selling toys, cars, textiles and shoes.

The use of price controls in Venezuela is not new and dates back to 2003 when they were first introduced by the then president Hugo Chavez. Initially the regulations were imposed on various foods and basic goods. For example, by 2009 maximum prices had been set for cooking oil, white rice, sugar, coffee, flour, margarine, pasta and cheese. Businesses often complained that the maximum prices set by the government were below the costs of production. For example after a maximum price of 2.15 Bolivares was placed on a kilo of rice, producers argued that the cost of producing a kilo of rice was 4.41 Bolivares.

The impact of the maximum prices in Venezuela appears to have been exactly what the theories in the economics textbooks would have predicted – shortages, long queues of people waiting outside shops and a flourishing black market. An article on the shortage of toilet rolls has been discussed in a previous article on this news site: Shortages in Venezuela- what’s the solution? However this has not stopped the Venezuelan government extending the scheme and increasing the number of products that have maximum prices imposed on them. In 2011 Hugo Chavez argued that the policy was required because:

The market has…become a perverse mechanism where big monopolies, the big trans-nationals and the bourgeoise dominate and ransack the people.

Economics textbooks often include some analysis of the impact of price ceilings on a competitive market. The effects on consumer surplus, producer surplus and deadweight welfare are usually discussed. However the potential administrative costs are rarely considered. The Venezuelan case helps to illustrate how in practise these costs could be quite significant.

For example, in April 2012 price controls in Venezuela were extended to a range of 19 products including fruit juice, toilet paper, nappies, soap, detergent, deodorant, toothpaste, baby food, floor polish, mineral water and razor blades. This caused a reduction in prices of between 4% and 25%. However this did not simply mean setting 19 different maximum prices because the goods were all sold in different quantities or different package sizes. For example a tube of toothpaste could be purchased in 4 different sizes – 50ml, 75ml, 100ml and 150 ml. Therefore officials had to set 4 different figures. Nappies were sold in 12 different package sizes ranging from10 nappies/packet to78 nappies/packet. Once again this meant that the administrators had to set 10 different maximum prices just for nappies. In total across the 19 products government officials had to set prices for 616 different individual items!! Companies were given just one month to adjust to the new legislation.

Whenever maximum prices are imposed on a competitive market both frustrated buyers and sellers have an incentive to evade them and trade illegally. Therefore the government established a number of organisations in an attempt to make sure the prices were enforced. One agency is called The National Superintendency of Fair Costs and Prices or Sundecop. Officials from this agency were sent out to 82 retail outlets in April 2012 to try to make sure that firms were sticking to the new regulated prices. They also printed and handed out leaflets to the public informing them of the changes. Another agency is called ‘The Institute for the Defense of People’s Access to Goods and Services’ or ‘Indepabis’. This organisation launched a new strategy in June 2012 in order to monitor compliance. This included the creation of a network called the Friends of Indepabis which would act as an information point for members of the public to report illegal pricing. A new complaints phone line was also introduced.

If president Maduro is granted the power to extend maximum prices to all consumer products, then one can only begin to imagine the extra administrative costs involved with implementing the policy.
