At the G7 conference in Bavaria on 7 and 8 June 2015, it was agreed to phase out the use of fossil fuels by the end of the century. But despite this significant objective, there were no short-term measures put in place to start on the process of achieving this goal. Nevertheless, the agreement contained commitments to further developments in carbon markets, elimination of fossil fuel subsidies, incentives for the development of green energy and support for developing countries in reducing hydrofluorocarbons.

The agreement also sent a strong message to the 21st United Nations International Climate Change conference scheduled to meet in Paris from 30 November to 11 December 2015. The G7 communiqué states that binding rules would be required if the target was to be met.

The agreement should enhance transparency and accountability including through binding rules at its core to track progress towards achieving targets, which should promote increased ambition over time. This should enable all countries to follow a low-carbon and resilient development pathway in line with the global goal to hold the increase in global average temperature below 2°C.

But many environmentalists argue that a more fundamental approach is needed. This requires a change in the way the environment is perceived – by both individuals and politicians. The simple selfish model of consumption to maximise consumer surplus and production to maximise profit should be rejected. Instead, the environment should be internalised into decision making.

What is more, there should be an integral ecology which brings together a wide range of disciplines, including economics, in analysing the functioning of societies and economies. Rather than being seen merely as a resource to be exploited, respect and care for the environment should be incorporated into our whole decision-making process, along with protecting societies and cultures, and rejecting economic systems that result in a growing divide between rich and poor.

In his latest encyclical, On care for our common home, Pope Francis considers integral ecology, not just in terms of a multidiciplinary approach to the environment but as an approach that integrates the objectives of social justice and care for the environment into an overarching approach to the functioning of societies and economies. And central to his message is the need to change the way human action is perceived at a personal level. Decision making should be focused on care for others and the environment not on the selfish pursuit of individual gain.

With a change in heart towards other people and the environment, what would be seen as externalities in simple economic models based on rational self-interested behaviour become internal costs or benefits. Care and compassion become the drivers for action, rather than crude self interest.

A key question, of course, is how we get here to there; how society can achieve a mass change of heart. For religious leaders, such as the Pope, the approach centres on spiritual guidance. For the secular, the approach would probably centre on education and the encouragement for people to consider others in their decision making. But, of course, there is still a major role for economic instruments, such as taxes and subsidies, rules and regulations, and public investment.

The UK general election is on May 7. In the campaign during the run-up to the election the economy will be a major issue. All parties will use economic data to claim that the economy has performed well or badly and that the prospects are good or bad. As economics students you will, no doubt, be asked to comment on these claims by your friends. So where can you get analysis of the data that is not biased towards one party or another?

One source is the Institute for Fiscal Studies. It is respected by politicians of all parties as an impartial presenter and analyser of economic data. In fact, it is fiercely independent. But at election time, when often quite dramatic claims are made by politicians, the IFS often comments on whether the data support such claims.

An example occurred when David Cameron claimed that if Labour were elected, working families would face a £3028 tax rise to fund the party’s spending commitments. The IFS said that the claim was misleading as, even on the Conservatives’ assumptions, it was was based on the cumulative increase over five years, not the annual increase, and was not per household but only per working household. The IFS also said that the Conservatives’ assumptions were wrong and not in accordance with the Charter for Budget Responsibility, with which the Labour party agreed.

Expect the IFS to criticise more claims as the election campaign progresses: not just by the Conservative party but by the other parties too. After all, the IFS is not partisan and is prepared to challenge false economic claims from whatever party. Expect also that the political parties will cherry pick whatever statements by the IFS seen to favour them or criticise their opponents.

You can also expect political bias in the newspapers that report the campaigns. Even when they present facts, how they present them and which facts they choose to include and which to ignore will be a reflection of their political bias. So even newspaper reporting of what the IFS says is likely to be selective and nuanced!

  2. Identify three series of macroeconomic data from at least two independent organisations. For what reasons might the data be (a) unreliable; (b) used by political parties to mislead the electorate?
  3. In what ways can political parties use economic data to their own advantage without falsifying the data?
  4. How may public-sector deficit and debt statistics be interpreted in ways to suit (a) the current government’s case that the public finances have been well managed; (b) the opposition case that the public finances have been badly managed?
  5. Use data to analyse an economic claim by each of at least three political parties and the extent to which the claims are accurate.
  6. The above links are to articles from four UK national newspapers: The Guardian, the Independent, The Telegraph and the Daily Mail (This is Money). Identify political bias in the reporting in each of the articles.

In the UK, we take it for granted that if you need to see a doctor, you go and give little, if any thought, to the cost. It may be petrol costs, time off work or the cost of a prescription, but beyond that, receiving treatment is free at the point of use. Funded through a progressive tax system, the NHS is seen as being one of the more equitable health care systems.

When a mother gives birth, the main thing she will have to worry about is the labour – and not whether to have certain painkillers or stay an extra night, because of the cost.

The International Federation of Health Plans (IFHP) looked at data on the cost of giving birth, based on insurance company payments. For someone living in the UK, the figures make for quite astonishing reading. In the USA, a normal delivery will cost $10,000, while a caesarean totals $15,000, meaning that giving birth in the USA is the most expensive place in the world. The article linked below takes the case of Mari Roberts, whose total delivery bill came to over $100,000. The insurance did cover it, but that’s not always the case. Medical bills in the United States are one of the leading reasons for bankruptcy and with these types of figures, perhaps it’s hardly surprising.

Other countries also see high costs for delivery, where expectant mothers really do need to give consideration to the length of their stay in hospital and perhaps even whether they are willing to forgo a pain-relieving drug and save some money. There is often said to be an efficiency–equity trade-off in the area of healthcare, with countries offering a free at the point of use service delivering an equitable system, but with a lack of responsiveness to the demands of the patients. In the UK, you don’t pay to see a doctor but, with a ‘free’ service, demand is understandably very high, thus creating a shortage and waiting lists. In countries, such as the USA, a higher price for treatment does limit demand, creating more inequity but a responsive system.

There are certainly lessons that can be learned from all health care systems and living in a developed country, we should certainly consider ourselves lucky. There are many countries where access to even the most basic health care is a luxury that most cannot afford. So, where does have the best health care system? I’ll leave that to you.

The New Year is a time for reflection and prediction. What will the New Year bring? What does the longer-term future hold? Here are two articles from The Guardian that look into the future.

The first, by Larry Elliott, considers a number of scenarios and policy options. Although not totally doom laden, the article is not exactly cheery in its predictions. Perhaps ‘life will go on’ and the global economy will muddle through. But perhaps a new recession is around the corner or, even worse, the world is at a tipping point when things are fundamentally changing. Unless policy-makers are careful, clever and co-ordinated, perhaps a new dark age may be looming. But who knows?

Which brings us to the second article, by Gaby Hinsliff. This argues that people are pretty hopeless at predicting. “History is littered with supposed dead certs that didn’t happen – Greece leaving the euro, the premature collapse of the coalition – and wholly unimagined events that came to pass.” And economists and financial experts are little better.

Two years ago, The Observer challenged a panel of City investors to pick a portfolio of stocks and rated their performance against that of Orlando, a ginger cat who selected his portfolio by tossing a toy mouse at a sheet of paper. Inevitably, the cat triumphed.

But is this fair? If capital markets are relatively efficient, stock prices today already reflect knowable information about the future, but clearly not unknowable information.

It’s the same with economies. When information is already to hand, such as a pre-announced tax change, then its effects, ceteris paribus, can be estimated – at least roughly.

But it’s the ‘ceteris paribus‘ assumption that’s the problem. Other things are not equal. The world is constantly changing and there are all sorts of unpredictable events that will influence the outcomes of economic policy and of economic decisions more generally. And central to the problem are people’s attitudes and confidence. Mood can swing quite dramatically, from irrational exuberance to deep pessimism. And such mood changes – often triggered by some exogenous factor, such as an international dispute, an election or unexpected economic news – can rapidly gather momentum and have significant effects.

Predicting the long-term future is both easier and more difficult: easier, in that short-term cyclical effects are less relevant; more difficult in that changes that have not yet happened, such as technological changes or changes in working practices, may themselves be key determinants of the future global economy.

One of the most salutary lessons is to look at predictions made in the past about the world today and at just how wrong they have proved to be. Perhaps we need to call on Orlando more frequently.

Questions

  1. Give some examples of factors that could have a major influence on the global economy, but which are unpredictable.
  2. Is economic forecasting still worthwhile? Explain.
  3. Look at some macroeconomic forecasts made in the past about the world today. You might want to look at forecasts of agencies such as the IMF, the OECD, the World Bank and the European Commission. You can find links in the Economics Network’s Economic Data freely available online. Explain why such forecasts have differed from the actual outcome.
  4. Why, if capital markets were perfect, might Orlando be just as good as a top investment manager at predicting the future course of share prices?
  5. In what ways is economic forecasting similar to and different from weather forecasting in its methods, its use of data and its reliability?

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.
