Tag: market share

Cloud computing is growing rapidly and has started to dominate many parts of the IT market. Cloud revenues are rising at around 25% per year and, according to Jeremy Duke of Synergy Research Group:

“Major barriers to cloud adoption are now almost a thing of the past, especially on the public-cloud side. Cloud technologies are now generating massive revenues for technology vendors and cloud service providers, and yet there are still many years of strong growth ahead.”

The market leader in cloud services (as opposed to cloud hardware) is Amazon Web Services (AWS), a subsidiary of Amazon. At the end of 2016, it had a market share of around 40%, larger than the next three competitors (Microsoft, Google and IBM), combined. AWS originated cloud computing some 10 years ago. It is set to have generated revenue of $13 billion in 2016.

The cloud computing services market is an oligopoly, with a significant market leader, AWS. But is the competition from other players in the market, including IT giants, such as Google, Microsoft, IBM and Oracle, enough to guarantee that the market stays competitive and that prices will fall as technology improves and costs fall?

Certainly all the major players are investing heavily in new services, better infrastructure and marketing. And they are already established suppliers in other sectors of the IT market. Microsoft and Google, in particular, are strong contenders to AWS. Nevertheless, as the first article states:

Neither Google nor Microsoft have an easy task since AWS will continue to be an innovation machine with a widely recognized brand among the all-important developer community. Both Amazon’s major competitors have an opportunity to solidify themselves as strong alternatives in what is turning into a public cloud oligopoly.

In an earlier post, Elizabeth looked at oligopolistic competition between supermarkets. Although supermarkets have been accused of tacit price collusion on many occasions in the past, price competition has been growing. And recent developments show that it is likely to get a lot fiercer as the ‘big four’ try to take on the ‘deep discounters’, Aldi and Lidl.

Part of the reason for the growth in price competition has been a change in shopping behaviour. Rather than doing one big shop per week in Tesco, Sainsbury’s, Asda or Morrisons, many consumers are doing smaller shops as they seek to get more for their money. A pattern is emerging for many consumers who are getting their essentials in Aldi or Lidl, their ‘special’ items in more upmarket shops, such as Waitrose, Marks & Spencer or small high street shops (such as bakers and ethnic food shops) and getting much fewer products from the big four. Other consumers, on limited incomes, who have seen their real incomes fall as prices have risen faster than wages, are doing virtually all their shopping in the deep discounters. As the Guardian article below states:

A steely focus on price and simplicity, against a backdrop of falling living standards that has sharpened customers’ eye for a bargain, has seen the discounter grab market share from competitors and transform what we expect from our weekly shop.

The result is that the big four are seeing their market share falling, as the chart shows. (Click here for a PowerPoint of the chart.) In the past year, Tesco’s market share has fallen from 29.9% to 28.1%, Asda’s from 17.8% to 16.3%, Sainsbury’s from 16.9% to 16.2% and Morrisons’ from 11.7% to 11.0%. By contrast, Aldi’s has risen from 3.9% to 5.4% and Lidl’s from 3.1% to 4.0%, while Waitrose’s has also risen, from 4.7% to 4.9%. And it’s not just market share that has been falling for the big four. Profits have also fallen, as have share prices. Sales revenues in the four weeks to 13 September are down 1.6% on the same period a year ago; sales volumes are down 1.9%.

But can the big four take on the discounters at their own game? Morrison’s has just announced a form of price match scheme called ‘Match & More’. If a shopper finds that a comparable grocery shop is cheaper in not only Tesco, Sainsbury’s or Asda, but also in Aldi or Lidl, then ‘Match & More users will automatically get the difference back in points on their card. Shoppers also will be able to collect extra points on hundreds of featured products and fuel’. When the difference has risen to a total £5 (5000 points), the shopper will get a £5 voucher at the till. The idea is to encourage customers to stay loyal to Morrisons.

But what if Tesco, Asda and Sainsbury’s do the same? What will be the impact on their prices and profits. Will there be a race to the bottom in prices, or will they be able to keep prices higher than the deep discounters, hoping that many customers will not cash in their vouchers?

But if effectively the big four felt forced to cut their prices to match Aldi and Lidl, could they afford to do so? This depends on their comparative average costs. At first sight, it might be thought that the big four could succeed in profitably matching the discounters, thereby clawing back market share. After all, they are much bigger and it might be thought that they would benefit from greater economies of scale and hence lower costs.

But it is not as simple as this. The discounters have lower costs than the big four. Their shops are typically in areas where rents or land prices are lower; their shops are smaller; they carry many fewer lines and thus gain economies of scale on each line; they have a much higher proportion of own-brand products; products are displayed in the boxes they come in, thus saving on the staff costs of unpacking them and placing them on shelves; they buy what is cheapest and thus do not always display the same brands.

So is Morrison’s a wise strategy? Will other supermarkets be forced to follow? Is there a prisoners’ dilemma here and, if so, is there any form of collusion in which the big four can engage which is not illegal? Can the big four differentiate themselves from the discounters and the up-market supermarkets in ways that will attract back customers?

It is worrying times for the big four.

  7. Why may Aldi and Lidl benefit from Morrisons’ strategy?

The supermarket industry is a classic example of an oligopoly. A market dominated by a few large companies, which is highly competitive and requires the companies to think about the reactions of the other competitors whenever a decision is made. Throughout the credit crunch, price cutting was the order of the day, as the big four tried to maintain market share and not lose customers to the low cost Aldi and Lidl. Morrisons, however, has found itself in exactly that position and is now looking to restructure to return to profitability.

Morrisons is well known for its fresh food, but it seems that with incomes still being squeezed, even this is insufficient to keep its customers from looking for cheaper alternatives. Morrisons’ market share has been in decline and its profits or the last financial year have been non-existent. It’s been losing ground to its big competitor, Tesco and part of this is due to the fact that Morrisons was late to enter the ‘Tesco metro’ market. It remained dependent on its large supermarkets, whereas Tesco saw the opportunity to expand onto the highstreets, with smaller stores. It was also late arriving to the online shopping business and while it has now developed more sophisticated IT systems, it did lose significant ground to Tesco and its other key competitors.

Another problem is that Morrisons has found itself unable to compete with the low cost supermarkets. The prices on offer at Morrisons are certainly not low enough to compete with prices at Aldi and Lidl and Morrisons has seen many of its customers switch to these cheaper alternatives. But Morrisons is fighting back and has announced plans to cut prices on a huge range of products across its stores. The fresh food aspect of the business will still remain and the hope is that the fresh food combined with cheaper price tags will allow Morrisons to re-gain lost ground to Tesco and take back some of its lost customers from the low-cost alternatives. However, it’s not just Morrisons that has been losing customers to the budget retailers. Tesco, Sainsbury’s and Asda have all lost market share to Aldi and Lidl, but it is Morrisons that has fared the worst.

The latest news on Morrisons’ profits and overall performance, together with its promise of restructuring and price cuts worth £1 billion has caused uncertainty for shareholders and this has reduced the value of shares. However, Morrisons’ Directors have tried to restore confidence by purchasing shares themselves. With expectations of price wars breaking out, the other supermarkets have also seen significant declines in their share values, with a total of £2 billion being wiped off the value of their shares collectively. The consequences of Morrisons’ performance will certainly continue: customers are likely to benefit from lower prices in all of the big four supermarkets, but investors may lose out – at least in the short run. The impact on jobs is uncertain and will certainly depend on how investors and customers react in the coming weeks. The following articles consider this sector.

UK Supermarkets: a prime example of an oligopoly. This industry is highly competitive and over the past decade, but particularly since the onset of the credit crunch, price wars have been a constant feature of this market. You could barely watch a full programme on commercial TV without seeing one of the big supermarkets advertising that their prices were lower than everyone else’s! So, despite oligopoly being towards the ‘least competitive’ end of the market structure spectrum, this is an example of just how competitive the market can actually be.

With household incomes being squeezed, in particular by another oligopolistic industry (energy) and with the ‘middle market’ being pinched by higher-end retailers and budget retailers, the supermarket sector is facing uncertain times. Asda’s sales growth has continued to slow and in response, the giant supermarket chain will be launching a £1 billion price-cutting campaign. Tesco is the market leader, but Sainsbury’s and Asda have been battling over the second spot. One of Asda’s selling points is its low prices. Perhaps not as low as Aldi and Lidl, but this new pricing strategy will aim to bring its prices further below Tesco, Sainsbury’s and Morrisons and close the gap with the two big discount supermarkets. As Andy Clarke, Asda’s Chief Executive, said:

We regard ourselves as the UK’s leading value retailer and it is against this backdrop that I have today set out our strategic priorities which will improve, extend and expand the business over the next five years.

So, what will be the impact of lower prices? It appears as though Asda is marketing itself towards the budget end of the pricing spectrum, perhaps aiming to become fiercer competitors with Aldi and Lidl and let Tesco and Sainsbury’s do battle with the higher-end retailers, such as Waitrose and Marks and Spencer. Lower prices should cause a substitution effects towards Asda’s products, as many of them will have relatively price elastic demand. If the other supermarkets don’t respond, this should lead to sales growth. However, the key to an oligopoly is interdependence: the actions of one firm will affect all other firms in the market. The implications then, are that Tesco may react to this pricing strategy by engaging in its own price cuts, especially as the Christmas period approaches. The characteristic of interdependence was evident in the aftermath of Asda’s announcement when shares in Tesco and Morrisons both fell, showing how the markets were responding.

Of course, there are many other factors that affect a consumer’s decision as to whether to shop at Asda, Tesco or any other big supermarket. In the area where I live, we have a Tesco and a Morrisons (a few years ago, we had neither!). I don’t shop at Asda, as the nearest branch is over 30 miles away – even if prices were significantly lower, it would be more expensive to get there and back and a lot less convenient. For others, it may be loyalty and not just of the ‘I’ve shopped there all my life’ kind! For some, clubcard vouchers from Tesco may be preferred to Asda’s offerings and thus tiny price differences between the supermarkets may have little effect on a consumer’s decision as to where to shop. Many products at supermarkets are relatively cheap and thus as the proportion of our income that we spend on these goods is pretty low, any change in price doesn’t cause much of an effect on our demand.

It’s not just a pricing strategy where money is being invested by Asda. More investment will be going into their online services and more stores will be created, kin particular in London and the South East where their presence is low, but demand appears to be high. Improving ‘product quality, style and design’ will also be on the agenda, all with the aim of boosting sales growth and securing its position as the second largest retailer in the sector, perhaps with a long term aim of one day overtaking Tesco.

The Big Four are well known: Deloitte, Ernst and Young, KPMG and PWC. They act as auditors for 90% of the UK’s stock-market listed companies. They have a very close relationship with the companies that they audit and because of this have faced criticism of not warning of the financial crisis. A further accusation is that the relationship between auditors and managers has become blurred.

In some sense, there is a problem of divorce of ownership from control. The companies that are audited by the Big Four have shareholders who are interested in profits and their dividends. But they employ managers who are responsible for the day-to-day running of the business. However, there are concerns that the auditors have become more concerned with meeting the interests of the managers and not of the shareholders. It has been suggested that the company’s management tend to ‘present their accounts in the most favourable light, whereas shareholder interests can be quite different.’ Laura Carstensen, the chair of the Audit Investigation Group said:

It is clear that there is significant dissatisfaction amongst some institutional investors with the relevance and extent of reporting in audited financial reports … management may have incentives to present their accounts in the most favourable light, whereas shareholder interests can be quite different.

The Big Four have been criticised for limiting competition in the industry. The Competition Commission has said that companies typically stay with the same auditing firm and this acts to limit competition. One suggestion to encourage competition is to enforce rotation of Auditors. However, the Big Four have said that the market remains competitive, ‘healthy and robust’ and that any enforcement as noted above would not be in the public interest. Other, smaller auditing companies have praised the preliminary report of the Competition Commission. One firm said:

No one solution will achieve market correction, but rather a combination of tendering requirements, encouragement of transparency and dialogue between auditors, companies and investors, and reform of outdated exclusionary practices should provide a backdrop for a healthier FTSE 350 audit market.

The report is not yet final, but the future of the Big Four is somewhat uncertain, especially with the European Commission’s desire to break them up. The following articles look at this industry.
