GDP is still the most frequently used indicator of a country’s development. When governments target economic growth as a key goal, it is growth in GDP to which they are referring. And they often make the assumption that growth in GDP is a proxy for growth in well-being. But is it time to leave GDP behind as the main indicator of national economic success? This is the question posed in the first of the linked articles below, from the prestigious science journal Nature.
As the article states:
Robert F. Kennedy once said that a country’s gross domestic product (GDP) measures “everything except that which makes life worthwhile”. The metric was developed in the 1930s and 1940s amid the upheaval of the Great Depression and global war. Even before the United Nations began requiring countries to collect data to report national GDP, Simon Kuznets, the metric’s chief architect, had warned against equating its growth with well-being.
GDP measures mainly market transactions. It ignores social costs, environmental impacts and income inequality. If a business used GDP-style accounting, it would aim to maximize gross revenue — even at the expense of profitability, efficiency, sustainability or flexibility. That is hardly smart or sustainable (think Enron). Yet since the end of the Second World War, promoting GDP growth has remained the primary national policy goal in almost every country
So what could replace GDP, or be considered alongside GDP? Should we try to measure happiness? After all, behavioural scientists are getting much better at 
understanding and measuring the psychology of human well-being (see the blog posts Money can’t buy me love and Happiness economics).
Or should we focus primarily on long-term issues of the sustainability of development? Or should we focus more on the distribution of income or well-being in a world that is becoming increasingly unequal?
Or should measures of well-being involve weighted composite indices involving things such as life-expectancy, education, housing, democratic engagement, leisure time, social mobility, etc. And, if so, how should the weightings of the different indicators be determined? The United Nations Development Programme (UNDP) produces annual Human Development Reports, where countries are ranked according to a Human Development Index. As the UNDP site states:
The breakthrough for the HDI was the creation of a single statistic which was to serve as a frame of reference for both social and economic development. The HDI sets a minimum and a maximum for each dimension, called goalposts, and then shows where each country stands in relation to these goalposts, expressed as a value between 0 and 1.
HDI is a composite of three sets of indicators: education, life expectancy and income (see). The UNDP since 2010 has also produced an Inequality-adjusted HDI (IHDI).
The IHDI will be equal to the HDI value when there is no inequality, but falls below the HDI value as inequality rises. The difference between the HDI and the IHDI represents the ‘loss’ in potential human development due to inequality and can be expressed as a percentage.
You can now build your own HDI for each country on the UNDP site by selecting from the following indicators: health, education, income, inequality, poverty and gender.
The Nature article considers a number of measures of progress and considers their relative merits. The other articles also look at measuring national progress and well-being and at the relationship between income per head and happiness. It is clear that focusing on GDP alone provides too simplistic an approach to measuring development.

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.

In December 2013, Uruguay passed a law permitting the growing, distribution and consumption of marijuana. The legislation comes into effect in April 2014. The state will regulate the industry to ensure good quality strains of the crop are grown and sold. It will also tax the industry.
Uruguay is the first country to legalise cannabis, but in July 2012, Colorado and Washington states in the USA passed laws permitting the sale and possession of small amounts of the drug for recreational use. (It was already legal to possess the drug for medical use.) The laws took effect a few months later. It is heavily taxed, however, especially in Washington, where it is taxed at a rate of 25% three times over: when it is sold to the processor; when the processor sells it to the retailer; and when the retailer sells it to the consumer. In Massachusetts, Nevada and Oregon, medical cannabis shops will be permitted to open this year. In the Netherlands, although the sale of cannabis is still illegal, ‘coffee shops’ are permitted to sell people up to 5 grams per day.
So should cannabis be legalised? People have very strong views on the subject and this can make a calm assessment of the issue more difficult. The economist’s approach to legalising cannabis involves seeking to identify and measure the costs and benefits of doing so. If the benefits exceed the costs, then it should be legalised; if not, it should remain illegal (or made illegal). The problem is that the size of the costs and benefits are not easy calculate as they involve estimates of things such as consumption levels, tax revenues, crime reduction, the effects on the consumption of other drugs, including legal drugs such as alcohol and tobacco.
Nevertheless, various estimates of these costs and benefits have been made and provide a basis for discussion.
Possible benefits of cannabis legalisation include: increased tax revenues for the government; reduction in crime, and hence reduction in law enforcement and prison costs; encouraging people with addiction problems to seek help, as they would not fear arrest; reduction in the price, benefiting users; regulating quality of the drug; reducing the consumption of alcohol and more dangerous drugs if these are substitutes for cannabis; moral arguments concerning freedom of individuals to choose their lifestyle.
Possible costs include: increased consumption of cannabis, with attendant health and social side effects; increased consumption of other drugs if they are complements, or if cannabis is an ‘entry level’ drug to harder drugs; moral objections to drug taking.
Clearly some of these costs and benefits are easier to measure than others. Moral arguments are almost impossible to assess quantitatively, even when various underlying moral standpoints are agreed.
The following articles look at recent events and at the arguments, both economic and non-economic.

As the old year gives way to the new, papers have been full of economic forecasts for the coming year. This year is no exception. The authors of the articles below give their predictions of what is to come for the global economy and, for the most part, their forecasts are relatively optimistic – but not entirely so. Despite a sunny outlook, there are various dark clouds on the horizon.
Most forecasters predict a higher rate of global economic growth in 2014 than in 2013 – and higher still in 2015. The IMF, in its October forecasts, predicted global growth of 3.6% in 2014 (up from 2.9% in 2013) and 4.0% in 2015.
Some countries will do much better than others, however. The USA, the UK, Germany and certain developing countries are forecast to grow more strongly. The eurozone as a whole, however, is likely to see little in the way of growth, as countries such as Greece, Spain, Portugal and Italy continue with austerity policies in an attempt to reduce their debt. 
Chinese growth has slowed, as the government seeks to rebalance the economy away from exports and investment in manufacturing towards consumption, and services in particular. It is still forecast to be 7.3% in 2014, however – well above the global average. Japanese growth has picked up in response to the three arrows of fiscal, monetary and supply-side policy. But this could well fade somewhat as the stimulus slows. The table shows IMF growth forecasts for selected countries and groups of countries to 2018.
Much will depend on what happens to monetary policy around the world. How quickly will monetary stimulus taper in the USA and in Japan? Will the ECB introduce more aggressively expansionary monetary policy? When will the Bank of England start raising interest rates?
Growth within countries is generally favouring those on higher incomes, with the gap between rich and poor set to continue widening over the coming years. The pay of top earners has continued to rise considerably faster than prices, while increasingly flexible labour markets and squeezed welfare budgets have seen a fall in living standards of many on low incomes. According to a Which? survey (reported in the Independent article below), in the UK:
Only three in ten expect their family’s situation to improve in the new year, while 60% said they are already dreading the arrival of their winter energy bill. The Which? survey also found that 13 million people could afford to pay for Christmas only by borrowing, with more than four in ten using credit cards, loans or overdrafts to fund their festive spending. A third of people (34%) also dipped into their savings, taking an average of £450 from their accounts.
If recovery is based on borrowing, with real incomes falling, or rising only very slowly, household debt levels are likely to increase. This has been stoked in the UK by the ‘Help to Buy‘ scheme, which has encouraged people to take on more debt and has fuelled the current house price boom. This could prove damaging in the long term, as any decline in confidence could lead to a fall in consumer expenditure once more as people seek to reduce their debts.
And what of the global banking system? Is it now sufficiently robust to weather a new crisis. Is borrowing growing too rapidly? Is bank lending becoming more reckless again? Are banks still too big to fail? Is China’s banking system sufficiently robust? These are questions considered in the articles below and, in particular, in the New York Times article by Gordon Brown, the former Prime Minister and Chancellor of the Exchequer.

There are a number of surveys that attempt to measure the spending intentions of people in the run up towards Christmas. For example a recent study carried out by YouGov found that people in the UK planned to spend an average of £599 on presents for their family and friends. This represented a 5.8% increase on the previous year. Planned total spending on Christmas was estimated to be a staggering £22 billion.
Respondents to another survey, carried out by the hotel chain Travelodge, stated that on average they planned to buy presents for 12 people. This study also found that the average expected spend on each present was £28.70 – an increase of £1.70 on the previous year. A rather obvious question for anyone interested in economics is whether this is either a sensible or an efficient way of allocating resources. One way to think about how an economist might approach this issue is to ask yourself the following questions after you have opened a present on Christmas day.
• How much money do you think the person who gave you the present paid for it?
• Ignoring the sentimental value, if you had not received this present how much would
you be willing to pay to purchase it?
Exactly 20 years ago the economist Joel Waldfogel posed questions very similar to these to a group of 86 students studying an intermediate microeconomics module at Yale University in the USA. On average the respondents to the questions estimated that friends and family had spent $438 on 
the gifts they had received that Christmas. Unfortunately their willingness to pay for these same gifts was $313 on average. Economists would argue that this is an example of economic inefficiency because the recipients’ valuation of the gifts – as measured by their willingness to pay – was only 71.5% of the price paid by the person who gave them the presents. This means that it is possible to make the person who received the gift better off without making the person who purchased the gift any worse off. This argument can be illustrated with a simple example.
Assume you have purchased a Liverpool football club shirt as a present for Sir Alex Ferguson and it cost you £50! Rather surprisingly Sir Alex likes the shirt but would have only been willing to pay £20 if he was buying it for himself. Imagine now that you have given him £50 cash instead of the shirt. This would not make you any worse off – your cash outlay would remain unchanged. However, Sir Alex would now be able to spend the £50 cash in a way which would give him far more satisfaction than the Liverpool football shirt would have given him. Sir Alex can therefore be made better off without making you worse off. The present in this example generates a deadweight welfare loss of £30. Waldfogel concluded from his later research based on a larger sample of people that, on average, people’s valuations of their presents is about 90% of the money actually spent on them. If this figure is accurate, it suggests that over £2 billion will be wasted in the UK this Christmas.
The size of the deadweight welfare loss depends on how well the person who is buying the present knows or understands the preferences of the recipient. The closeness of age, friendship or family relationship are all likely to influence the accuracy of this knowledge. Interestingly, Waldfogel found that presents from grandparents to grandchildren were the most inefficient: i.e. the difference between the recipient’s valuation of the gift and the price paid for the present was the greatest. The study also found that grandparents were more likely to give their grandchildren cash gifts.
Do economists always advise people to give cash as presents? Thankfully the dismal science can find some positive things to say about giving gifts. The previous analysis can be criticised in a number of different ways. It assumes that the recipients are perfectly informed about all the potential gifts that are available. If the person buying the present can find an item that the recipient was unaware of, then it is possible that economic welfare might be increased. It has also been assumed that the pleasure or value people obtain from an item is not influenced by who has purchased it. It may be the case that people place a greater value on an item when it is a gift from somebody else. In the previous example, perhaps Sir Alex would value the Liverpool shirt at £60 if you had purchased it for him as a present. The analysis has also ignored the possibility that the person buying the present derives pleasure from trying to find a gift that they think the person would like. Perhaps people feel a ‘warm glow’ when they see the happiness of somebody opening their present on Christmas day.
A final interesting economic explanation for buying presents is that they might act as an effective signal in a situation where there is asymmetric information. It can be argued that this is the case in relationships where people have private information about their true feelings towards one another. One way of communicating these feelings is by simply telling someone how you feel about them. However, this might not be an effective signal, as someone who does not have such strong feelings could say the same things as someone who does! However, by taking the time and trouble to buy someone a present that they really like, you are able to signal more effectively how you really feel about them. The signal can be particularly strong if the person buying the present really dislikes shopping. Just giving someone cash, or not taking the time to buy a present the person really likes, might signal that you simply could not be bothered to exert the effort because your feelings are not that strong. The potential consequences of giving your partner money are amusingly demonstrated in the following clip: The Economics of Seinfeld: What’s the right Gift to give; cash?
Perhaps giving presents instead of cash is an economically efficient way of dealing with situations where asymmetric information is potentially an important issue.
