Vetting vets

The Competition and Markets Authority (CMA) is proposing to launch a formal Market Investigation into anti-competitive practices in the UK’s £2bn veterinary industry (for pets rather than farm animals or horses). This follows a preliminary investigation which received 56 000 responses from pet owners and vet professionals. These responses reported huge rises in bills for treatment and medicines and corresponding rises in the cost of pet insurance.

At the same time there has been a large increase in concentration in the industry. In 2013, independent vet practices accounted for 89% of the market; today, they account for only around 40%. Over the past 10 years, some 1500 of the UK’s 5000 vet practices had been acquired by six of the largest corporate groups. In many parts of the country, competition is weak; in others, it is non-existent, with just one of these large companies having a monopoly of veterinary services.

This market power has given rise to a number of issues. The CMA identifies the following:

  • Of those practices checked, over 80% had no pricing information online, even for the most basic services. This makes is hard for pet owners to make decisions on treatment.
  • Pet owners potentially overpay for medicines, many of which can be bought online or over the counter in pharmacies at much lower prices, with the pet owners merely needing to know the correct dosage. When medicines require a prescription, often it is not made clear to the owners that they can take a prescription elsewhere, and owners end up paying high prices to buy medicines directly from the vet practice.
  • Even when there are several vet practices in a local area, they are often owned by the same company and hence there is no price competition. The corporate group often retains the original independent name when it acquires the practice and thus is is not clear to pet owners that ownership has changed. They may think there is local competition when there is not.
  • Often the corporate group provides the out-of-hours service, which tends to charge very high prices for emergency services. If there is initially an independent out-of-hours service provider, it may be driven out of business by the corporate owner of day-time services only referring pet owners to its own out-of-hours service.
  • The corporate owners may similarly provide other services, such as specialist referral centres, diagnostic labs, animal hospitals and crematoria. By referring pets only to those services owned by itself, this crowds out independents and provides a barrier to the entry of new independents into these parts of the industry.
  • Large corporate groups have the incentive to act in ways which may further reduce competition and choice and drive up their profits. They may, for example, invest in advanced equipment, allowing them to provide more sophisticated but high-cost treatment. Simpler, lower-cost treatments may not be offered to pet owners.
  • The higher prices in the industry have led to large rises in the cost of pet insurance. These higher insurance costs are made worse by vets steering owners with pet insurance to choosing more expensive treatments for their pets than those without insurance. The Association of British Insurers notes that there has been a large rise in claims attributable to an increasing provision of higher-cost treatments.
  • The industry suffers from acute staff shortages, which cuts down on the availability of services and allows practices to push up prices.
  • Regulation by the Royal College of Veterinary Surgeons (RCVS) is weak in the area of competition and pricing.

The CMA’s formal investigation will examine the structure of the veterinary industry and the behaviour of the firms in the industry. As the CMA states:

In a well-functioning market, we would expect a range of suppliers to be able to inform consumers of their services and, in turn, consumers would act on the information they receive.

Market failures in the veterinary industry

The CMA’s concerns suggest that the market is not sufficiently competitive, with vet companies holding significant market power. This leads to higher prices for a range of vet services. However, the CMA’s analysis suggests that market failures in the industry extend beyond the simple question of market power and lack of competition.

A crucial market failure is asymmetry of information. The veterinary companies have much better information than pet owners. This is a classic principal–agent problem. The agent, in this case the vet (or vet company), has much better information than the principal, in this case the pet owner. This information can be used to the interests of the vet company, with pet owners being persuaded to purchase more extensive and expensive treatments than they might otherwise choose if they were better informed.

The principal–agent problem also arises in the context of the dependant nature of pets. They are the ones receiving the treatment and, in this context, are the principals. Their owners are the ones acquiring the treatment for them and hence are the pets’ agents. The question is whether the owners will always do the best thing for their pets. This raises philosophical questions of animal rights and whether owners should be required to protect the interests of their pets.

Another information issue is the short-term perspective of many pet owners. They may purchase a young and healthy pet and assume that it will remain so. However, as the pet gets older, it is likely to face increasing health issues, with correspondingly increasing vet bills. But many owners do not consider such future bills when they purchase the pet. They suffer from what behavioural economists call ‘irrational exuberance’. Such exuberance may also occur when the owner of a sick pet is offered expensive treatment. They may over-optimistically assume that the treatment will be totally successful and that their pet will not need further treatment.

Vets cite another information asymmetry. This concerns the costs they face in providing treatment. Many owners are unaware of these costs – costs that include rent, business rates, heating and lighting, staff costs, equipment costs, consumables (such as syringes, dressings, surgical gowns, antiseptic and gloves), VAT, and so on. Many of these costs have risen substantially in recent months and are reflected in the prices pet owners are charged. With people experiencing free health care for themselves from the NHS (or other national provider), this may make them feel that the price of pet health care is excessive.

Then there is the issue of inequality. Pets provide great benefits to many owners and contribute to owners’ well-being. If people on low incomes cannot afford high vet bills, they may either have to forgo having a pet, with the benefits it brings, or incur high vet bills that they ill afford or simply go without treatment for their pets.

Finally, there are the external costs that arise when people abandon their pets with various health conditions. This has been a growing problem, with many people buying pets during lockdown when they worked from home, only to abandon them later when they have had to go back to the office or other workplace. The costs of treating or putting down such pets are born by charities or local authorities.

The CMA is consulting on its proposal to begin a formal Market Investigation. This closes on 11 April. If, in the light of its consultation, the Market Investigation goes ahead, the CMA will later report on its findings and may require the veterinary industry to adopt various measures. These could require vet groups to provide better information to owners, including what lower-cost treatments are available. But given the oligopolistic nature of the industry, it is unlikely to lead to significant reductions in vets bills.

A body blow to Body Shop?

On 12 February, it was announced that The Body Shop UK was entering administration. With 199 shops across the country, if this leads to the collapse of the business, some 2000 jobs will be lost. The business has been struggling since 2020 and poor sales this last Christmas led the new owners, the pan-European alternative investment firm, Aurelius, to appoint administrators.

This could potentially begin an insolvency process that could result in the closure of some or all of the shops. This would spell the end of an iconic brand that, since its founding in 1976, has been associated with natural, ethically sourced and environmentally friendly products. Aurelius has already sold The Body Shop business in most of mainland Europe and in parts of Asia to an unnamed buyer. It is unclear what will happen to the approximately 2800 stores and 8000 employees in 70 countries outside the UK.

Origins of The Body Shop1

The Body Shop was founded in 1976 and shot to fame in the 1980s. It stood for environmental awareness and an ethical approach to business. But its success had as much to do with what it sold as what it stood for. It sold natural cosmetics – Raspberry Ripple Bathing Bubbles and Camomile Shampoo – products that proved immensely popular with consumers.

Its profits increased from a little over £1m in 1985 (€1.7m) to approximately £65m (€77.5m) in 2012. Although profits then slipped, falling to €65.3m in 2014 and €54.8m in 2015, its profit growth in new markets over that same period was 12.4%.

Sales revenue, meanwhile, grew even more dramatically, from £4.9m in 1985 to approximately €967.2m in 2015. By 2015, Body Shop International had over 3100 stores, operating in 61 countries.

What made this success so remarkable is that The Body Shop did virtually no advertising. Its promotion stemmed largely from the activities and environmental campaigning of its founder, Anita Roddick, and the company’s uncompromising claim that it sold only ‘green’ products and conducted its business operations with high ethical standards. It actively supported green causes such as saving whales and protecting rainforests, and it refused to allow its products to be tested on animals. Perhaps most surprising in the world of big business at the time was its high-profile initiative ‘trade not aid’, whereby it claimed to pay ‘fair’ prices for its ingredients, especially those supplied by people in developing countries who were open to exploitation by large companies.

The growth strategy of The Body Shop focused upon developing a distinctive and highly innovative product range, and at the same time identifying these products with major social issues of the day, such as the environment and animal rights.

Its initial expansion was based on a process of franchising, where individuals opened Body Shops which were then supplied by the company with its range of just 19 products. Then, in 1984 the company went public. Following its flotation, the share price rose from just 5p to a high of 370p in 1992.

In the 1990s, however, sales growth was less rapid. By 1998, earnings had collapsed by 90% and the share price fell to 117p. Shareholders forced Anita Roddick to step down as Chief Executive, but for a while she and her husband remained as co-chairs. In 2002, they stepped down as co-chairs, by which time profits had fallen to £20.4m. In 2003 she was awarded in knighthood and became Dame Anita Roddick. Sales then grew rapidly from 2004 to 2006 from €553m to €709m.

Acquisition of The Body Shop by L’Oréal

A dramatic event, however, occurred in 2006 when The Body Shop was sold to the French cosmetics giant, L’Oréal, which was 26% owned by Nestlé, The event resulted in the magazine Ethical Consumer downgrading The Body Shop’s ethical rating from 11 out of 20 to a mere 2.5 and calling for a boycott of the company. Three weeks after the sale, the daily BrandIndex recorded an 11 point drop in The Body Shop’s consumer satisfaction rating from 25 to 14.

There were several reasons for this. L’Oréal’s animal-testing policies conflicted with those of The Body Shop and L’Oréal was accused of being involved in price-fixing with other French perfume houses. L’Oréal’s part-owner, Nestlé, was also subject to various criticisms for ethical misconduct, including promoting formula milk rather than breast milk to mothers with babies in developing countries and using slave labour in cocoa farms in West Africa.

Anita Roddick, however, believed that, by taking over The Body Shop, L’Oréal would develop a more ethical approach to business. Indeed, it did publicly recognise that it needed to develop its ethical and environmental policies.

L’Oréal adopted a new Code of Business Ethics in 2007 and gained some external accreditation for its approach to sustainability and ethics. It was ranked as one of the world’s 100 most ethical companies by Ethisphere in 2007 and, in 2016, it was again part of this list for the seventh time.

L’Oréal set itself three targets as part of its environmental strategy (2005–15), including a 50% reduction in greenhouse gas emissions, water consumption and waste per finished product unit. It made a donation of $1.2m to the US Environment Protection Agency to help bring an end to animal testing and, in March 2013, it announced a ‘total ban on the sale in Europe of any cosmetic product that was tested on animals or containing an ingredient that was tested on animals after this date.’ It also promised that ‘By 2020, we will innovate so that 100% of products have an environmental or social benefit.’

Sadly, Anita Roddick died in 2007 and so was not able to witness these changes.

L’Oréal also looked to inject greater finance into the company aimed at improving the marketing of products. In autumn 2006 a transactional website was launched and there have been larger press marketing campaigns. Profits continued to rise in 2006 and 2007, but fell back quite dramatically from €64m in 2007 to €36m in 2008 as recession hit the high streets. They fell by a further 8% in 2009, but significant growth was seen in the following three years: 2010, up 20.3% to €65.3m; 2011, up 4.3% to €68.1m; 2012, up 13.8% to €77.5m.

From L’Oréal to Natura to Aurelius to ?

From 2013, the financial performance of The Body Shop deteriorated. Profits fell by 38% in 2016 to just €34m, with sales falling by 5%. In June 2017, L’Oréal announced that it had agreed to sell The Body Shop for €1bn (£877m) to Natura Cosmeticos, the largest Brazilian cosmetics business. Natura was awarded ‘B Corp’ status in 2014 as it met certain standards for environmental performance, accountability and transparency. In 2019, The Body Shop was separately certified as a B Corp.

Initial indications for The Body Shop under its new owners seemed good, with net revenue rising by 36% in 2018 and 6.3% in 2019. 2020 saw strong growth in sales, with a rise in online sales more than offsetting the effect of store closures during the pandemic. Its market share peaked in 2020 at 1.4%. However, with the cost-of-living crisis following the pandemic and the Russian invasion of Ukraine, many consumers switched to cheaper brands and cheaper outlets, such as Boots and Superdrug, sacrificing environmental and ethical concerns in favour of value for money. As a result, The Body Shop’s market share fell, dropping to 0.8% in 2022 and not picking up in 2023.

This prompted Natura to sell the business to Aurelius. Aurelius hoped to revitalise The Body Shop by promoting its core values and through partnerships or concessions with major retailers, such as John Lewis or Next. However, as we saw above, after a poor Christmas and a weaker capital base and higher cost commitments than initially thought by Aurelius, the new owner filed to put The Body Shop into administration.

What will come of the administration process remains to be seen. Perhaps some of the more profitable stores will be saved; perhaps there will be an expansion of the online business; perhaps partnerships will be sought with major retailers. We shall see.

Unlocking happiness: how jobs shape young lives in developing nations

Have you ever wondered how your job affects your happiness? We all know that not all jobs are created equal. Some are awesome, while others … not so much. Well, it turns out that employment status and the type of work you do can have a big impact on how you feel – especially in developing countries where labour markets are usually tighter and switching between jobs can be more difficult.

A recent study by Carmichael, Darko and Vasilakos (2021) uses survey data from Ethiopia, Peru, India and Vietnam to answer this very question. The study found that the quality of work is a big deal when it comes to how young people feel. Not all jobs are ‘good jobs’ that automatically make you feel great. Although your wellbeing is likely to be higher when you’re in employment than when you’re not, there are certain job attributes that can push that ‘employment premium’ up or down. This is especially important to understand in countries like many in sub-Saharan Africa, where there aren’t many formal jobs, and people often end up overqualified for what they do.

What job attributes lead to higher wellbeing?

What then are the job attributes that are correlated with higher levels of wellbeing? The first is money: Okay, we know money can’t buy happiness, but it can certainly make life easier. We were therefore hardly surprised to find a positive and statistically significant association between hourly earnings and wellbeing.

We were also not surprised to find that a ‘poor working environment’ has a strong and highly significant negative effect on wellbeing.

Finally, feeling proud of your work is also found to be a strongly significant determinant of your wellbeing. After all, people tend to excel in things they like doing, which is probably part of the ‘transmission mechanism’ between ‘work pride’ and ‘subjective wellbeing’.

Which one of these attributes did you think had the greatest effect on wellbeing? Let me guess, many of you will say ‘earnings’. But then you would be wrong. Earnings were indeed positively associated with wellbeing and statistically significant at just about the 10% level, whereas work pride was very strongly statistically significant at the 1% level and had an effect on wellbeing that was four times greater than hourly earnings.

Putting yourself in a poor working environment on the other hand would reduce your wellbeing by almost twice as much as the earnings coefficient.

Policy implications

What does all this mean for policy-makers? If we want to make life better for young people in low-income countries, we need to tackle the problems from multiple angles.

First, young people need to be helped to get the skills they need for the job market. This can be done through things like training programmes and apprenticeships. However, not all of these programmes are created equal. Some have great results, and others not so much.

But that’s not the whole story. In many countries, there’s a massive informal job market. It’s a place where people work but often don’t have the rights or protections that formal employees do. So, even if young people get trained, they might not find the ‘good’ jobs they’re hoping for.

Changes also need to be made on a much bigger scale. This often includes decentralising public investment to include rural areas, improving infrastructure, and encouraging private investment. Strengthening labour market rules and social protection can help too, by making sure that work is safe and fair.

In a nutshell, where you work and what kind of work you do can make a big difference to how you feel.

Conclusions

If policy-makers want to help young people in low-income countries, they need both to give them the skills they require and to create better job opportunities. But policy-makers also need to make bigger changes to the way things work, like boosting production and making sure jobs are safe and fair.

In the end, it’s about making life better for young people around the world. Let’s keep working on it!

Subscription traps: policy responses to a market failure

Policy makers have become increasingly concerned about what the US Federal Trade Commission (FTC) describe as ‘negative option marketing’. These are marketing deals that contain the following feature:

a term or condition that allows a seller to interpret a customer’s silence, or failure to take affirmative action, as an acceptance of an offer.

For example, companies such as Amazon, Apple, Spotify and Netflix may offer students a 3-month free trial or 3-month introductory offer (at a special lower price) for movie and music streaming services. However, many of these subscription contracts contain an example of negative option marketing – auto renewal clauses.

Problems with auto-renewal contracts

The inclusion of an auto-renewal clause means that if a customer fails to cancel the subscription at the end of the three-month period, the subscription automatically reverts to its full price. The full-price contract then continues to roll-over indefinitely unless the customer takes a pre-specified action to terminate the deal. Inattentive consumers could end up paying subscription prices that far exceed their willingness to pay.

Auto-renewal contracts are not just an issue with free trials/introductory offers. Some people may purchase subscription contracts at the full price and then forget about them. These consumers could end up paying fees for months after they have effectively stopped using the service.

Another potential problem with the use of auto-renewal contracts, is businesses deliberately making the cancellation process more complex than it needs to be. In many cases it takes just one click to sign up for the subscription, but multiple clicks through a series of menus to cancel. Some businesses do not provide consumers with the option to cancel online and, instead, they are forced to phone a number that is often very busy.

Effects on consumer welfare

To what extent do these problems caused by auto-renewal reduce consumer welfare? What evidence do we have?

Research by Citizens Advice found that just over one in four people (26 per cent) had signed up to a subscription by accident. 58 per cent of this group forgot to cancel a free trial, while 21 per cent did not realise that the free trial would automatically roll-over to a full-price subscription. This seems to be a particular issue for those on low incomes with 46 per cent of people on Universal Credit signing up to a subscription by accident.

Analysis by the Department for Business and Trade (DBT) has tried to estimate the value of these unwanted subscriptions. The study found that consumers spent £602 million on unwanted subscriptions where a free or reduced-price trial had been rolled over to the full price. The same study also found that £573 million was spent on subscriptions that people had forgotten about.

One in five people in the Citizens Advice study who tried to cancel a subscription found the process difficult. The DBT estimates that cancellation difficulties led to £382 million being spent on unwanted subscriptions.

UK Government response

In response to these findings, the government introduced the Digital Markets, Competition and Consumers Bill into Parliament in April 2023.

Provisions in the Bill seek to standardise the information that businesses must provide consumers before they sign up for subscription contracts. For example, in the future, firms will have to display prominently (a) any auto-renewal provisions, (b) whether the price increases after a specified period, (c) details about how consumers can terminate the contract and (d) cooling-off periods.

The Bill also stipulates that businesses will have to provide consumers with reminders when a free/reduced-price trial period is about to end and/or a subscription is about to renew automatically. They must also make it easy to exit contracts and remove any unnecessary steps.

The government initially considered an additional measure that would force businesses to provide consumers with the option to take out any subscription without auto-renewal.

Citizens Advice strongly supported this policy. They argued that not only should consumers be given the choice, but that auto-renewal should not be the default i.e. people would have to opt-in to auto-renewal subscriptions.

However, after the consultation process for the Bill, the government decided against introducing this additional measure. Businesses have also argued that the other elements of the policy are too prescriptive.

The economics of fake reviews

Imagine a situation where you are thinking of buying a good and so you go to an e-commerce marketplace such as Amazon, eBay, Etsy or Onbuy. How confident are you about the quality of the different brands/makes that are listed for sale on these digital platforms? How do you choose which product to buy? Is the decision strongly influenced by customer reviews and rating?

When a customer is choosing what to buy it raises an interesting question: to what extent can the true quality of the different goods/services be observed at the time of purchase? Although perfect observability is highly unlikely, the level of consumer information about a product’s true quality will vary between different types of transaction.

For example, when consumers can physically inspect and test/try a product in a shop, it can help them to make more accurate judgements about its quality and condition. This poses a problem for online sellers of high-quality versions of a good. Without the ability to inspect the item physically, consumers may be unsure about its characteristics. They may worry that the online description provided by the seller deliberately misrepresents the true quality of the item.

Consumers may have other concerns about the general reliability of online sellers. For example, in comparison to buying the product from a physical store, consumers may worry that:

  • They will have to wait longer to receive the good. In many cases, when consumers purchase a product from a high-street store, they can walk away with the item and start using it straight away. When purchasing on line, they may end up waiting weeks or even longer before the product is finally delivered.
  • It will be more difficult to return the product and get a refund.
  • They are more likely to come across fraudulent sellers who have set-up a fake website.

This greater level of uncertainty about the true characteristics of the product and the general reliability of the seller will have a negative impact on consumers’ willingness to pay for all goods. This impact is likely to be particularly strong for high-quality versions of a product. If consumers’ willingness to pay falls below the reservation price of many sellers of high-quality goods, then the market could suffer from adverse selection and market failure.

Are there any within-market arrangements that could help deal with this issue? One possibility is for sellers to signal the quality of their products by posting consumer ratings and reviews. If consumers see that a product has many positive ratings, then this will increase their confidence in the quality of the product and so increase their willingness to pay. This could then reduce both levels of asymmetric information and the chances of adverse selection occurring in the market,

There is survey evidence that many people do read consumer reviews when choosing products on line and are heavily influenced by the ratings.

The problem of fake reviews

However, when consumers look at these reviews can they be sure that they reflect consumers’ honest opinions and/or actual experience of using the good or service? Firms may have an incentive to manipulate and post fake reviews. For example, they could:

  • Deliberately fail to display negative reviews on their website while claiming that all reviews are published.
  • Use internet bots to post thousands of automated reviews.
  • Take positive reviews from competitors’ websites and post them on their own website.
  • Pay some customers and/or employees to write and post 5-star reviews on their own website.
  • Pay some customers and/or employees to write and post 1-star reviews on their competitors’ websites.
  • Set up a website that they claim is independent and use it to provide positive endorsements of their own products.

If the benefits of this type of behaviour outweigh the costs, then we would expect to see fake reviews posted on websites. If their use becomes widespread, then the value of posting genuine reviews will fall. The market may then settle into what economists call a ‘pooling equilibrium’.

What evidence do we have on the posting of fake reviews? Given their nature, it is difficult to collect reliable data and there are large variations in the reported figures. One recent study found evidence of fake reviews being purchased and posted for approximately 1500 products on Amazon.

Can consumers screen reviews and identify those that are more likely to be fake? The following are some tell-tale signs.

  • Products that receive a large number of very positive reviews over a short period (i.e. a few days). There are then long periods before the product receives another large number of positive reviews.
  • A high percentage of 5-star reviews. Two, three and four start reviews are more likely to be genuine.
  • Reviews that specifically mention a rival firm’s products.
  • Reviewers who have given very high ratings to large number of different products over a short period of time.
  • Reviews that include photos/videos.

Competition authorities around the world have been investigating the issue and the Competition and Markets Authority has announced plans to introduce new laws that make the purchasing and posting of fake reviews illegal.
