Category: Essentials of Economics: Ch 04

The economic climate remains uncertain and, as we enter 2017, we look towards a new President in the USA, challenging negotiations in the EU and continuing troubles for High Street stores. One such example is Next, a High Street retailer that has recently seen a significant fall in share price.

Prices of clothing and footwear increased in December for the first time in two years, according to the British Retail Consortium, and Next is just one company that will suffer from these pressures. This retail chain is well established, with over 500 stores in the UK and Eire. It has embraced the internet, launching its online shopping in 1999 and it trades with customers in over 70 countries. However, despite all of the positive actions, Next has seen its share price fall by nearly 12% and is forecasting profits in 2017 to be hit, with a lack of growth in earnings reducing consumer spending and thus hitting sales.

The sales trends for Next are reminiscent of many other stores, with in-store sales falling and online sales rising. In the days leading up to Christmas, in-store sales fell by 3.5%, while online sales increased by over 5%. However, this is not the only trend that this latest data suggests. It also indicates that consumer spending on clothing and footwear is falling, with consumers instead spending more money on technology and other forms of entertainment. Kirsty McGregor from Drapers magazine said:

“I think what we’re seeing there is an underlying move away from spending so much money on clothing and footwear. People seem to be spending more money on going out and on technology, things like that.”

Furthermore, with price inflation expected to rise in 2017, and possibly above wage inflation, spending power is likely to be hit and it is spending on those more luxury items that will be cut. With Next’s share price falling, the retail sector overall was also hit, with other companies seeing their share prices fall as well, although some, such as B&M, bucked the trend. However, the problems facing Next are similar to those facing other stores.

But for Next there is more bad news. It appears that the retail chain has simply been underperforming for some time. We have seen other stores facing similar issues, such as BHS and Marks & Spencer. Neil Wilson from ETX Capital said:

“The simple problem is that Next is underperforming the market … UK retail sales have held up in the months following the Brexit vote but Next has suffered. It’s been suffering for a while and needs a turnaround plan … The brand is struggling for relevancy, and risks going the way of Marks & Spencer on the clothing front, appealing to an ever-narrower customer base.”

Brand identity and targeting customers are becoming ever more important in a highly competitive High Street that is facing growing competition from online traders. Next is not the first company to suffer from this and will certainly not be the last as we enter what many see as one of the most economically uncertain years since the financial crisis.

An earlier post on this site described a recent row between Tesco and Unilever that erupted when Unilever attempted to raise the prices it charges Tesco for its products. Unilever justified this because its costs have increased as a result of the UK currency depreciation following the Brexit decision.

It also appears that more general concerns that the fall in the value of sterling would lead to higher retail prices were prevalent around the time that the Tesco Unilever dispute came to light. Former Sainsbury’s boss, Justin King, made clear that British shoppers should be prepared for higher prices. He also said that:

Retailers’ margins are already squeezed. So there is no room to absorb input price pressures and costs will need to be passed on. But no one wants to be the first to break cover. No business wants to be the first to blame Brexit for a rise in prices. But once someone does, there will be a flood of companies because they will all be suffering.

It is interesting to consider further why the Tesco and Unilever case was the first to make the headlines and why their dispute was resolved so quickly. In addition, what are the more general implications for the retail prices consumers will have to pay?

Arguably, Unilever saw itself as having a strong hand in negotiations with Tesco because its product portfolio includes a wide variety of must-stock brands, including Pot Noodles, Marmite and Persil, that are found in 98% of UK households..

Unilever has been criticised for using the currency devaluation as an excuse to justify charging Tesco more, since most of its products are made in the UK. However, Unilever was quick to point outthat commodities it uses in the manufacture of products are priced in US dollars, so the currency devaluation can still affect the cost of products that it manufactures in the UK. In addition, Unilever’s chief financial officer, Graeme Pitkethly, insisted that price increases due to rising costs were a normal part of doing business:

We are taking price increases in the UK. That is a normal devaluation-led cycle.

On the other hand, even if the cost increases faced by Unilever are genuine, it is interesting to speculate whether it would have been so quick to adjust its prices downwards in response to a currency appreciation. After all, a commonly observed phenomenon across a range of markets is ‘rockets and feathers’ pricing behaviour i.e. prices going up from a cost increase more quickly than they go down following an equivalent cost decrease.

Compared to Unilever, some other suppliers are likely to have less bargaining power – in particular, those competing in highly fragmented markets and those producing less branded products. In such markets the suppliers may be forced to accept cost increases. For example, almost 50% of butter and cheese consumed in the UK comes from milk sourced from EU markets. Protecting such suppliers is one of the key roles of the Grocery code of conduct that the UK competition agency has put in place.

From Tesco’s point of view it will have benefited from good publicity by doing its best to protect consumers from price hikes. Helen Dickinson, chief executive of the British Retail Consortium, said:

Retailers are firmly on the side of consumers in negotiating with suppliers and improving efficiencies in the supply chain to control the inflationary pressure that is building through the devaluation of the pound.

However, it is also clear that Tesco had its own motives for resisting increased costs for Unilever’s products. In such situations both supplier and retailer should be keen to avoid a situation where they both impose their own substantial mark-ups at each stage of the supply chain. It is well established that this creates a double mark-up and not only harms consumers, but also the supplier and retailer themselves. Instead, the firms have an incentive to use more complex contractual arrangements to solve the problem. For example, suppliers may pay slotting allowances to get a place on the retailers’ shelves in exchange for lower retail mark-ups.

It has also been claimed that cutthroat competition in the supermarket industry, especially from discounter retailers Aldi and Lidl, made Tesco particularly keen to prevent price rises. Some arguments suggest that these discounters will be best placed to benefit from the currency devaluation as they sell more own brands, have a limited range, the leanest supply chains and benefit from substantial economies of scale. On the other hand, they source more of their products from abroad and it has been suggested that:

A fall in sterling will push prices up for everyone who sources products from Europe, but Aldi and Lidl will be affected more than most.

One prediction suggests that the overall impact of the currency depreciation on food prices will be an increase of around 3%. This may be particularly worrisome given concerns that the impact will fall most heavily on benefit claimants and other low-income households.

Outside of the food industry, Mike Rake, the chairman of BT, has highlighted the fact that:

Imported mobile phones and broadband home hubs were already 10% more expensive and the cost would have to be passed on to consumers in the near future.

It is therefore clear that the currency devaluation has the potential to create substantial tensions in the supply-chain agreements across a range of markets. The impact on the firms involved and on consumers will depend upon a wide range of factors, including the competitiveness of the markets, the nature of the firms involved and their bargaining power. Furthermore, evidence from an earlier currency depreciation in Latin America makes clear that the price elasticity of demand will be another factor that determines the impact price rises have.

Finally, it is also worth noting that a potential flip side of the currency depreciation is a boost for UK exports. However, it has been suggested that the manufacturing potential to take advantage of this in the UK is limited. In addition, even the manufacturing that does take place, for example in the car industry, often relies on components imported from abroad.

The articles below examine the rise of the sharing economy and how technology might allow it to develop. A sharing economy is where owners of property, equipment, vehicles, tools, etc. rent them out for periods of time, perhaps very short periods. The point about such a system is that the renter deals directly with the property owner – although sometimes initially through an agency. Airbnb and Uber are two examples.

So far the sharing economy has not developed very far. But the development of smart technology will soon make a whole range of short-term renting contracts possible. It will allow the contracts to be enforced without the need for administrators, lawyers, accountants, bankers or the police. Payments will be made electronically and automatically, and penalties, too, could be applied automatically for not abiding by the contract.

One development that will aid this process is a secure electronic way of keeping records and processing payments without the need for a central authority, such as a government, a bank or a company. It involves the use of ‘blockchains‘ (see also). The technology, used in Bitcoin, involves storing data widely across networks, which allows the data to be shared. The data are secure and access is via individuals having a ‘private key’ to parts of the database relevant to them. The database builds in blocks, where each block records a set of transactions. The blocks build over time and are linked to each other in a logical order (i.e. in ‘chains’) to allow tracking back to previous blocks.

Blockchain technology could help the sharing economy to grow substantially. It could significantly cut down the cost of sharing information about possible rental opportunities and demands, and allow minimal-cost secure transactions between owner and renter. As the IBM developerWorks article states:

Rather than use Uber, Airbnb or eBay to connect with other people, blockchain services allow individuals to connect, share, and transact directly, ushering in the real sharing economy. Blockchain is the platform that enables real peer-to-peer transactions and a true ‘sharing economy’.

A row erupted in mid-October between Tesco, the UK’s biggest supermarket, and Unilever, the Anglo-Dutch company. Unilever is the world’s largest consumer goods manufacturer with many well-known brands, including home care products, personal care products and food and drink. Unilever, which manufactures many of its products abroad and uses many ingredients from abroad in those manufactured in the UK, wanted to charge supermarkets 10% more for its products. It blamed the 16% fall in the value of sterling since the referendum in June (see the blog Sterling’s slide).

Tesco refused to pay the increase and so Unilever halted deliveries of over 200 items. As a result, several major brands became unavailable on the Tesco website. The dispute was dubbed ‘Marmitegate’, after one of Unilever’s products.

This is a classic case of power on both sides of the market: a powerful oligopolist, Unilever, facing a powerful oligopsonist, Tesco. With rising costs for Unilever resulting from the falling pound, either Unilever had to absorb the costs, or Tesco had to be prepared to pay the higher prices demanded by Unilever, passing some or all of them onto customers, or there had to be a compromise, with the prices Tesco pays to Unilever rising, but by less than 10%. A compromise was indeed reached on 13 October, with different price increases for each of Unilever’s products depending on how much of the costs are in foreign currencies. Precise details of the deal remained secret.

An interesting dynamic in the dispute was that Tesco and Unilever were acting as ‘champions’ for retailers and suppliers respectively. Other supermarkets were also facing price rises by Unilever. Their reactions were likely to depend on what Tesco did. Similarly, other suppliers were facing rising costs because of the falling pound. Their reactions might depend on how successful Unilever was in passing on its cost increases to retailers.

This example of ‘countervailing power’, or ‘bilateral oligopoly’, helps to illustrate just how much the consumer can gain when a powerful seller is confronted by a powerful buyer. The battle was been likened to that between two ‘gorillas’ of the industry. Its ramifications throughout industry will be interesting.

Short-termism is a problem which has dogged British firms and is part of the explanation of low investment in the UK. Shareholders, many of which are large pension funds and other financial institutions, are more concerned with short-term returns than long-term growth and productivity. Likewise, senior managers’ rewards are often linked to short-term performance rather than the long-term health of the company.

But the stakeholders in companies extend well beyond owners and senior managers. Workers, consumers, suppliers, local residents and the country as a whole are all stakeholders in companies.

So is the current model of capitalism fit for purpose? According to the new May government, workers and consumers should be represented on the boards of major British companies. The Personnel Today article quotes Theresa May as saying:

‘The people who run big businesses are supposed to be accountable to outsiders, to non-executive directors, who are supposed to ask the difficult questions. In practice, they are drawn from the same, narrow social and professional circles as the executive team and – as we have seen time and time again – the scrutiny they provide is just not good enough.

We’re going to change that system – and we’re going to have not just consumers represented on company boards, but workers as well.’

This model is not new. Many countries, such as France and Germany, have had worker representatives on boards for many years. There the focus is often less on short-term profit maximisation and more on the long-term performance of the company in terms of a range of indicators.

Extending this model to stakeholder groups more generally could see companies taking broader social objectives into account. And the number of companies which put corporate social responsibility high on their agenda could increase significantly.

And this approach can ultimately bring better returns to shareholders. As the first The Conversation article below states:

This is something that research into a ‘Relational Company’ model has found – by putting the interests of all stakeholders at the heart of their decision making, companies can become more competitive, stable and successful. Ultimately, this will generate greater returns for shareholders.

While CSR has become mainstream in terms of the public face of some large corporations, it has tended to be one of the first things to be cut when economic growth weakens. The findings from Business in the Community’s 2016 Corporate Responsibility Index suggest that many firms are considering how corporate responsibility can positively affect profits. However, it remains the case that there are still many firms and consumers that care relatively little about the social or natural environment. Indeed, each year, fewer companies take part in the CR Index. In 2016 there were 43 firms; in 2015, 68 firms; in 2014, 97 firms; in 2013, 126 firms.

In addition to promising to give greater voice to stakeholder groups, Mrs May has also said that she intends to curb executive pay. Shareholders will be given binding powers to block executive remuneration packages. But whether shareholders are best placed to do this questionable. If shareholders’ interests are the short-term returns on their investment, then they may well approve of linking executive remuneration to short-term returns rather than on the long-term health of the company or its role in society more generally.

When leaders come to power, they often make promises that are never fulfilled. Time will tell whether the new government will make radical changes to capitalism in the UK or whether a move to greater stakeholder power will remain merely an aspiration.
