When building supply and demand models, the assumption is usually made that both producers and consumers act in a ‘rational’ way to achieve the best possible outcomes. As far as producers are concerned, this would mean attempting to maximise profit. As far as consumers are concerned, it would mean attempting to achieve the highest satisfaction (utility) from their limited budget. This involves a cost–benefit calculation, where people weigh up the costs and benefits of allocating their money between different goods and services.

For consumers to act rationally, the following assumptions are made:

  • Consumer choices are made independently. Their individual choices and preferences are not influenced by other people’s, nor do their choices and preferences impact on other people’s choices.
  • The consumer’s preferences are consistent and fixed.
  • Consumers have full information about the products available and alternatives to them.
  • Given the information they have and the preferences they hold, consumers will then make an optimal choice.

Black Friday can be seen as a perfect occasion for consumers to get their hands on a bargain. It is an opportunity to fulfil a rational need, for example if you were needing to replace a household appliance but were waiting until there was a good deal before committing to a purchase.

The assumption that people act rationally has been at the forefront of economic theory for decades. However, this has been questioned by the rise in behavioural economics. Rather than assuming that all individuals are ‘rational maximisers’ and conduct a cost–benefit analysis for every decision, behavioural economists mix psychology with economics by focusing on the human. As humans, we do not always behave rationally but, instead, we act under bounded rationality.

As economic agents, we make different decisions depending on our emotional state that differ from the ‘rational choice’ assumption. We are also influenced by our social networks and often make choices that provide us with immediate gratification. Given this, Black Friday can also be viewed as a great opportunity to fall prey to irrational and emotional shopping behaviours.

Black Friday originated in the USA and is the day after Thanksgiving. During this annual shopping holiday, retailers typically offer steep discounts to kick off the holiday season. The Black Friday shopping phenomenon is less than a decade old in the UK but it’s now an established part of the pre-Christmas retail calendar. Between 2010 and 2013, Black Friday gradually built up momentum in the UK. In 2014, Black Friday became the peak pre-Christmas online sales day and many online retailers haven’t looked back.

Arguably, from a behavioural economist’s perspective, the big problem with Black Friday is that all the reasons consumers possibly have to partake can be largely illusory. Consumers are bombarded with the promise of one-off deals, large discounts, scarce products, and an opportunity to get their holiday shopping done all at once. However, on Black Friday, our rational decision-making faculties are tested, just as stores are trying their hardest to maximise consumers’ mistakes.

There are many ‘behavioural traps’ that consumers often fall into. The following two are most likely to occur on Black Friday:

  • Scarcity and loss aversion. Shoppers may fear that they will miss out on the best sales deals available if they don’t buy it now. Retailers commonly spark consumers’ interest by highlighting limited stocks available for a limited time only, which raises the perceived value of these goods. This sense of scarcity can further trigger the need to buy now, increasing the ‘Fear of Missing Out’. Consumers therefore need to ask themselves if they are really missing out if they don’t buy it now? And is the discount worth spending the money today, or is there something else I should be spending it on or saving for?
  • Sunk cost fallacy. Once consumers have started to invest, they often struggle to close out investments that prove unprofitable. On Black Friday, customers have already made the initial investment of getting up early, driving to the shops, finding parking and waiting in a queue, before they have purchased anything. Therefore, they will be inclined to buy more than they initially went for. It is important therefore to think about each purchase in isolation.

This year, however, there is also the added complication of the rising cost of living. Whilst this may deter some consumers from unnecessary, impulse purchases, some consumers are using Black Friday as an opportunity to stock up on expected future purchases, hedging against likely price rises over the coming months.

It is thought that more consumers will be looking for a combination of high quality but low price to make sure their purchases are affordable and can last for a long time. According to PwC, many consumers have closely monitored their favourite brands in anticipation that big-ticket electronics, more pricey winter wear or Christmas stocking fillers will be discounted. Consumers are also in search of bargains more than ever given rising inflation. This would suggest a shift in attitude, meaning consumers will be more aware of what they cannot afford rather than giving in to emotional temptation brought on by Black Friday.

Retailers are fully aware of the cognitive biases that surround Black Friday and take full advantage of them. ‘Cyber Monday’ follows right after Black Friday, giving retailers an extra opportunity for them to keep those ‘urgent’ or ‘unmissable’ sales going and increase their revenues.

Black Friday is one of the biggest shopping days of the year. However, the way retailers approach it is growing increasingly mixed. Stores such as Amazon, Argos, Currys and John Lewis have started offering Black Friday deals much earlier in the month, leading some to refer to the event as ‘Black November’. Other stores, such as M&S and Next, didn’t take part at all this year.

Ultimately, Consumers can use insights from behavioural economics to empower them to make more rational decisions in such circumstances: ones that better align with their individual budgets. Nevertheless, the Black Friday sales mania can trigger our deepest emotional and cognitive responses that lead to unnecessary spending.

When people think about healthcare in the UK they tend to associate it with the NHS. However, there is a £5 billion private healthcare market. Concerns have been expressed about the lack of effective competition in this sector and it has been investigated by the competition authorities over a 5-year period.

Approximately 4 million people in the UK have a private medical insurance policy. The majority of these are paid for by employers, although some people pay directly. Four companies dominate the health insurance market (AXA PPP, Bupa, Pru Health and Aviva) with a combined market share of over 90%.

Health insurance companies purchase healthcare services for their policy holders from private hospitals. The majority of private hospitals in the UK are owned by the following businesses – BMI, HCA, Nuffield, Ramsey and Spire. Some concerns have been expressed about the lack of competition between private hospitals in some areas of the country.

After its initial analysis into the sector, the Office of Fair Trading (OFT) referred the case to the Competition Commission (CC) in April 2012 to carry out a full market investigation. This process was then taken over by the Competition and Markets Authority (CMA) when it replaced the OFT and CC. The final report was published on April 2nd 2014.

One specific region that was identified in this report as having a lack of effective competition was central London for patients with health insurance. In particular it was concluded that:

The market in central London was heavily concentrated and HCA had a dominant market position – its aggregated share of admissions across 16 specialities (e.g. Oncology, Cardiology, Neurology, Dermatology etc.) was 45% to 55%.
There were significant barriers to entry including substantial sunk costs. A particular issue for a new entrant or existing business was the problem of securing suitable sites in central London to build new hospitals and in obtaining planning permission. It was pointed out in the report that the market structure in central London had changed very little in the previous 10 years despite a rapidly growing demand for private healthcare.
HCA was charging insured patients higher prices for similar treatments than its leading rival – The London Clinic. HCA was also found to be making returns that were in excess of the cost of capital.

One of the key recommendations of the report was that HCA should be forced to sell–off one or two of the hospitals that it owned in central London to increase the level of competition.

Unsurprisingly HCA was very unhappy with the decision and applied to the Competition Appeal Tribunal (CAT) for a review of the case. During this review, economists working for HCA found errors with the analysis carried out by the CMA into the pricing of health services for insured customers.

In January 2015 the CAT concluded that the findings and recommendations of the report on insured patients in central London should be overturned and the CMA should reconsider the case. In November 2015 the CMA announced that having reviewed the case it had come to a similar set of conclusions: i.e. there was a lack of effective competition and HCA should be forced to sell off two of its hospitals in London.

HCA still claimed that the pricing analysis was incorrect because it did not fully take into account that HCA treated patients with more complex conditions than TLC and that was why their prices were higher.

On March 22nd 2016 the CMA announced that it had reversed its ruling and HCA would no longer be expected to sell off any of its hospitals. The reason given for this change in recommendation was the appearance of new entrants into the market. For example, Cleveland Clinic a US-based private healthcare provider has purchased a long-term lease on a property in Belgravia, central London. It plans to convert the office space into a private hospital with 2015 beds.

A spokesperson for Bupa commented that:

“The CMA has confirmed again that there isn’t enough competition in central London, with HCA dominating the private hospital market and charging higher prices. We ask the CMA to act now to address this gap.”

It will be interesting to see the impact these new entrants have on the market in the future.

Questions

  1. Define sunk costs using some real-world examples.
  2. Why might the existence of sunk costs create a barrier to entry?
  3. Draw a diagram to illustrate why a profit-maximising business with significant market power might charge higher prices than one in a very competitive environment.
  4. What is the cost of capital? Explain why returns that are greater than the cost of capital might be evidence that a firm is making excessive profits.
  5. Draw a diagram to illustrate the impact of new entrants in a market.

A key economic principle is that rational decision making requires thinking at the margin. This involves a comparison of the additional (or marginal) benefits and costs of an activity.

An example of such rational behaviour would be deciding to drink one more beer or spending one more hour studying only if the additional benefits were greater than the additional costs. The optimum is where marginal benefit equals marginal cost.

And this applies to firms too. A firm maximises its profits by producing the output at which marginal revenue is equal to marginal cost.

However, a recent book by the American business guru Clayton Christensen argues that thinking in this way can be a problem. A recent article in the Guardian describes a story he tells of the time he refused to play for his university basketball team in a national final which took place on a Sunday and therefore conflicted with his religious beliefs. His decision involved sticking to his principles rather than thinking at the margin. For him, whilst the marginal cost of sacrificing these principles just once may well have been small compared to the resulting benefits, the eventual cost would be much higher.

Christensen also suggests that similar arguments can apply to firm decision making. The above article provides an example he uses of decisions made by executives at the Blockbuster video chain. When smaller rivals started offering movies by mail, Blockbuster instead continued to invest in its existing video store business model. This eventually proved disastrous for the company. The explanation given for this is that building on previous investments made more sense than setting up a mail-order arm which would cannibalise their existing business. On the other hand, an alternative explanation may be that executives at Blockbuster were irrationally allowing sunk costs to affect their decision making.
