Many of you reading the articles on this website will be just about to start, or will have just started, studying economics at university. For some of you this will involve building on the knowledge you obtained prior to university, whereas for others it will be the first time you have ever studied the subject before. Will studying economics change the way you behave? Should it come with a health warning?
Can studying economics change the way you think and behave? The subject is often sold to prospective students on the grounds that it can. For example it is stated on the Economics Network’s Why Study Economics? website that
The economic way of thinking can help us make better choices
However, is it possible that studying economics could change people’s behaviour in a way that would be to the detriment of society? Some observers have argued that it can. They have suggested that students might be influenced by some of the assumptions that are made in traditional economic theory.
As social scientists, economists are always trying to analyse human behaviour. However, people vary in many different ways and have very diverse preferences. If we want to build a theory that predicts how people will behave and respond in different situations, then some type of simplifying assumptions are inevitable.
Traditionally one of the key simplifying assumptions that economists have used in their theories of human behaviour is that people make decisions in their own self-interest. There is some debate about exactly what self-interest means. For example it could be argued that giving £10 to charity is acting in your own self-interest if it gives you more pleasure than spending that £10 on yourself. However, in many of the economic theories that you first study in economics a narrow meaning of self-interest tends to be used. This is clearly illustrated by the following quote from Milgrom and Roberts. Referring to economic theory they state that:
It is often assumed that people behave as if they were entirely motivated by narrow, selfish concerns
It is important to make it clear that economists are not assuming that people behave in a selfish manner all of the time. Instead, they are assuming that the people in their theories are acting in a selfish manner. The value of making this assumption is whether the predictions about human behaviour that follow from using it are supported by evidence from the real world.
Some researchers have argued that when people study economic theory built on this assumption it makes them more likely to behave in a selfish way. The evidence for this comes from a range of research papers. Here are some findings:
Economics students were more likely than those studying other subjects to recommend the most expensive plumber to a student society if that plumber offered the student a side payment.
Students took part in an experiment in a computer room where they could either keep the money they had been given or donate it to a public good. On average the economics students kept more of the money.
Economics professors gave less money to charity than professors of other subjects such as psychology and sociology.
Some studies also found that selfish people were more likely to choose economics as a subject to study and became more selfish after they had studied it for some time.
If you are about to begin your study of economics then perhaps you should take care that your behaviour outside the classroom is not being unduly influenced by some of the assumptions you are learning about inside the classroom. On a more practical note perhaps you should avoid sharing a restaurant bill or buying rounds of drinks when in the company of other economists!!!
However on a brighter note, the evidence in these papers can be interpreted in a number of different ways. There are even some studies that found economics students were less selfish than those on other courses.

When you think about John Lewis, you think of a large department store. It is a department store celebrating its 150th anniversary. Many large retailers, such as John Lewis, have expanded their product range throughout their history and have grown organically, moving into larger and more prominent locations. What’s the latest location? St Pancras station.
The idea of a click-and-collect store has grown in popularity over the past decade. With more and more people working and leading very busy lives, together with the growth of online shopping, it is the convenience of this type of purchase which has led to many retailers developing click-and-collect. Indeed, for John Lewis, 33% of its internet sales do come through click-and-collect. However, John Lewis is going a step further and its new strategy is reminiscent of companies like Tesco. If you just need to pop into Tesco to get some milk, you’re likely to go to the local Tesco express. The first mover advantage of Tesco in this market was vital.
John Lewis is unusual in that it is owned by its employees and this ownership structure has proved successful. Despite a long history, John Lewis has moved with the times and this latest strategy is further evidence of that. In today’s world, convenience is everything and that is one of the key reasons behind its new St Pancras convenience store. It will allow customers to purchase items and then collect them on their way to and from work – click-and-commute, but it will also provide customers with an easily accessible place to buy electronic equipment and a range of household goods. The retail director, Andrew Murphy said:
In the battleground of convenience, we are announcing a new way for commuters to shop with us … Customers spend a huge amount of time commuting, and our research shows that making life easier and shopping more convenient is their top priority.
This appears to be the first of many smaller convenience stores, enabling John Lewis to gain a presence in seemingly impossible places, given the normal size of such Department stores. For many people, commuting to and from work often involves waiting at transport hubs – one of the big downsides to not driving. So it seems sensible for such an established retailer to take advantage of commuters waiting for their train or plane to arrive, who have time to kill. The following articles consider this new direction for an old retailer.

Questions
- What are the advantages and disadvantages of the organisational and ownership structure of John Lewis?
- How would you classify this new strategy?
- How do you think this new strategy will benefit John Lewis in terms of its market share, revenue and profit?
- Is it likely that John Lewis will be able to target new customers with this new convenience store strategy?
- How important is a first-mover advantage when it comes to retail? Using game theory, can you create a game whereby there is clear first mover advantage to John Lewis?
Profits are maximised where marginal cost equals marginal revenue. And in a perfectly competitive market, where price equals marginal revenue, profits are maximised where marginal cost equals price. But what if marginal cost equals zero? Should the competitive profit-maximising firm give the product away? Or is there simply no opportunity for making a profit when there is a high degree of competition?
This is the dilemma considered in the articles linked below. According to Jeremy Rifkin, what we are seeing is the development of technologies that have indeed pushed marginal cost to zero, or close to it, in a large number of sectors of the economy. For example, information can be distributed over the Internet at little or no cost, other than the time of the distributor who is often willing to do this freely in a spirit of sharing. What many people are becoming, says Rifkin, are ‘prosumers’: producing, sharing and consuming.
Over the past decade millions of consumers have become prosumers, producing and sharing music, videos, news, and knowledge at near-zero marginal cost and nearly for free, shrinking revenues in the music, newspaper and book-publishing industries.
What was once confined to a limited number of industries – music, photography, news, publishing and entertainment – is now spreading.
A new economic paradigm – the collaborative commons – has leaped onto the world stage as a powerful challenger to the capitalist market.
A growing legion of prosumers is producing and sharing information, not only knowledge, news and entertainment, but also renewable energy, 3D printed products and online college courses at near-zero marginal cost on the collaborative commons. They are even sharing cars, homes, clothes and tools, entirely bypassing the conventional capitalist market.
So is a collaborative commons a new paradigm that can replace capitalism in a large number of sectors? Are we gradually becoming sharers? And elsewhere, are we becoming swappers?

World leaders are meeting at the World Economic Forum in Davos, in the Swiss Alps. This annual conference is an opportunity for politicans, economists and businesspeople from around the world to discuss the state of the world economy and to consider policy options.
To coincide with the conference, the BBC’s Newsnight has produced the following slide show, which presents some economic facts about the world economy. The slide show provides no commentary and there is no commentary either in this blog – just some questions for you to ponder.
Using the economics you’ve learned so far, try answering these questions, which focus on the reasons for the patterns in the figures, the likely future patterns and the policy implications.

Questions
- Go through each of the slides in the Newsnight presentation and select the ones of most interest to you. Then, as an economist, provide an explanation for them.
- Identify some patterns over time in the statistics. Then project forward 20 years and discuss whether the patterns are likely to have changed and, if so, why.
- What policies could governments adopt to reverse any undesirable trends you have identified? How likely are these policies to be implemented and how successful are they likely to be?
A constant feature of the UK economy (and of many other Western economies) has been record low interest rates. Since March 2009, Bank Rate has stood at 0.5%. Interest rates have traditionally been used to keep inflation on target, but more recently their objective has been to stimulate growth. However, have these low interest rates had a negative effect on the business environment?
Interest rates are a powerful tool of monetary policy and by affecting many of the components of aggregate demand, economic growth can be stimulated. This low-interest rate environment is an effective tool to stimulate consumer spending, as it keeps borrowing costs low and in particular can keep mortgage repayments down. However, this policy has been criticised for the harm it has been doing to savers – after all, money in the bank will not earn an individual any money with interest rates at 0.5%! Furthermore, there is now a concern that such low interest rates have led to ‘zombie companies’ and they are restricting the growth potential and recovery of the economy.
A report by the Adam Smith Institute suggests that these ‘zombie companies’ have emerged in part by the low-interest environment and are continuing to absorb resources, which could otherwise be re-allocated to companies with more potential, productivity and a greater contribution to the economic recovery. During a recession, there will undoubtedly be many business closures, as aggregate demand falls, sales and profits decline until eventually the business becomes unviable and loans cannot be repaid. Given the depth and duration of the recent recessionary period, the number of business closures should have been very large. However, the total number appears to be relatively low – around 2% or 100,000 and the report suggests that the low interest rates have helped to ‘protect’ them.
Low interest rates have enabled businesses to meet their debt repayments more easily and with some banks being unwilling to admit to ‘bad loans’, businesses have benefited from loans being extended or ‘rolled over’. This has enabled them to survive for longer and as the report suggests, may be preventing a full recovery. The report’s author, Tom Papworth said:
Low interest rates and bank forbearance represent a vast and badly targeted attempt to avoid dealing with the recession. Rather than solving our current crisis, they risk dooming the UK to a decade of stagnation … We tend to see zombies as slow-moving and faintly laughable works of fiction. Economically, zombies are quite real and hugely damaging, and governments and entrepreneurs cannot simply walk away.
The problem they create is that resources are invested into these companies – labour, capital, innovation. This creates an opportunity cost – the resources may be more productive if invested into new companies, with greater productive potential. The criticism is that the competitiveness of the economy is being undermined by the continued presence of such companies and that this in turn is holding the UK economy back. Perhaps the interest rate rise that may happen this time next year may be what is needed to encourage the re-allocation of capital. However, a 0.5 percentage point rise in interest rates would hardly be the end of the world for some of these companies. Perhaps a more focused approach looking at restructuring is the key to their survival and the allocation of resources to their most productive use. The following articles and the report itself consider the case of the trading dead.
