Ministers from around the world met in Durban in the first two weeks of December 2011 to hammer out a deal on tackling climate change. The aim was that this would replace the Kyoto Treaty, due to expire at the end of 2012.

International climate change agreements are particularly difficult to achieve, as there are several market failures involved. Also, there is considerable ‘gaming’, as each country seeks to negotiate a deal that benefits the world as a whole but which minimises the disadvantages to their own particular country.

The conference ended on the 11 December with a last-minute deal. Both developed and developing countries would for the first time work on a legally binding agreement to limit emissions. This would be drawn up by 2015 and to come into force after 2020. The following articles assess the significance of the agreement and whether it represents real progress or little more than a deal to work on a deal.

Questions

  1. What was agreed at the Durban Climate Change Conference?
  2. Why is it difficult to get agreement on measures to tackle climate change? How is game theory relevant to explaining the difficulties in reaching an agreement?
  3. How would you set about establishing the ‘optimal’ amount of emissions reductions?
  4. Why will the market fail to provide the optimal amount of emissions reductions?
  5. Why was it felt not possible for a legally binding international agreement to come into force before 2020?

When people shop in supermarkets they often look for what’s on special offer. After all, everyone likes a bargain. About 35–37% of supermarket items are on special offer at any one time and around 50% of the money spent by customers is on such items.

But things aren’t always as they seem. Supermarkets use clever marketing to persuade people that they’re getting a good deal, while sometimes it’s nothing of the sort. Examples include putting up prices for a while and then reducing them again saying “huge reduction”; or promoting an offer of, say, “three for £2”, when you could buy an individual item for 60p; or using the word “now” £2.50 to imply that the previous price was higher, when in fact it wasn’t; or selling a double-sized “value pack” for more than double the price of the regular size. These tricks are commonplace in supermarkets.

Sometimes the wary consumer will be able to find out which offers are genuine, but it’s not always that easy. And even if you do buy something at a genuine discount, is it something you really want? Or have you been persuaded to buy it simply because it’s on offer? Supermarkets study consumers’ psychology. They find clever ways of promoting products to make us feel that we have done well in getting a bargain.

The following programme in the BBC’s Panorama series looks at the big four supermarkets in the UK – Tesco, Asda, Sainsbury’s and Morrisons – which between then have 68% of supermarket sales. It gives examples of some of the not so special offers and how consumers are being hoodwinked.

Questions

  1. What types of misleading offers are identified in the Panorama report?
  2. For what reasons are consumers “taken in” by such offers? Does this imply that consumers are irrational?
  3. Does intense oligopolistic competition between the big four supermarkets lead to lower prices?
  4. How is it possible for two supermarkets to claim that they are cheaper than the other? How would you decide which supermarket was generally cheaper?
  5. Why might it be difficult for an independent agency to do a comparison of prices of different supermarket chains?

Divided we stand is the title of a new report by the Organisation for Economic Co-operation and Development (OECD). Its sub-title is “Why inequality keeps rising”. The report shows how the gulf between rich and poor has widened in most countries, both developed and developing. As the introduction states:

In the three decades prior to the recent economic downturn, wage gaps widened and household income inequality increased in a large majority of OECD countries. This occurred even when countries were going through a period of sustained economic and employment growth.

The report analyses the major underlying forces behind these developments. Its conclusion is that inequality looks set to continue widening, especially with the worldwide economic slowdown and rise in unemployment. However, the report says that “there is nothing inevitable about growing inequalities. Globalisation and technological changes offer opportunities but also raise challenges that can be tackled with effective and well-targeted policies.”

So just what is the extent of inequality? How has it changed over time? And what can be done to reduce inequality? The webcast produced by the OECD to accompany the report looks at the problem, and the report and articles look at what can be done about it.

Questions

  1. Why may inequality be seen as a ‘bad thing’ for society as a whole and not just the poor?
  2. Does it matter for the poor if rich people’s incomes grow at a greater rate than those of the poor so long as the incomes of the poor do indeed grow?
  3. Explain what is meant by the Gini coefficient. What has happened to the Gini coefficient over the past few years across the world?
  4. Are there any common explanatory features in the economies of those countries where income inequality is growing rapidly? Similarly, are there any common explanatory features in the economies of those countries where income inequality is not growing, or growing only very slowly?
  5. What are the causes of rising inequality?
  6. Identify policies that can be adopted to tackle growing inequality.
  7. What problems arise from policies to reduce inequality by (a) reducing inequalities in disposable income; (b) providing more free services to all, such as healthcare and education? How might these problems be mitigated?

The meeting of EU leaders on night of Thursday/Friday 8/9 December was the latest in a succession of such meetings designed to solve the eurozone’s problems (see also, Part A, Part B and Part C in this series of posts from earlier this year).

Headlines in the British press have all been about David Cameron’s veto to a change in the Treaty of Lisbon, which sets the rules of the operation of the EU and its institutions. Given this veto, the 17 members of the eurozone and the remaining 9 non-eurozone members have agreed to proceed instead with inter-governmental agreements about tightening the rules governing the operation of the eurozone.

In this news item we are not looking at the politics of the UK’s veto or the implications for the relationship between the UK and the rest of the EU. Instead, we focus on what was agreed and whether it will provide the solution to the eurozone’s woes: to fiscal harmonisation; to stimulating economic growth; to bailing out severely indebted countries, such as Italy; and to recapitalising banks so as to protect them from sovereign debt problems and the private debt problems that are likely to rise as the eurozone heads for recession.

The rules on fiscal harmonisation represent a return to something very similar to the Stability and Growth Pact, but with automatic and tougher penalties built in for any country breaking the rules. What is more, eurozone member countries will have to submit their national budgets to the European Commission for approval.

The agreement has generally been well received – stock markets rose in eurozone countries on the Friday by around 2%. But the consensus of commentators is that whilst the agreement might prove a necessary condition for rescuing the euro, it will not be a sufficient condition. Expect a Part E (and more) to this series!

Meanwhile the following articles provide a selection of reactions from around the world to the latest agreement.

A key determinant of our economy’s rate of growth over the year ahead is likely to be the behaviour of households and, in particular, the rate of growth in consumer (or household) spending. In other words, your appetite for spending will help to determine how quickly the economy grows. The importance of household spending for the economy is straightforward to understand given that it accounts for roughly two-thirds of the total demand for firms’ goods and services, i.e. two-thirds of aggregate demand. In its November 2011 Economic and Fiscal Outlook the Office for Budget Responsibility presents it forecasts for economic growth and household spending. The following table summarises these forecasts.

OBR Forecasts (annual real percentage change)

2011 2012 2013 2014 2015 2016
GDP 0.9 0.7 2.1 2.7 3.0 3.0
Consumption –1.1 0.2 1.2 2.2 2.7 2.9
Disposable income –2.3 –0.3 0.9 2.0 2.5 2.5

Source: Economic and Fiscal Outlook (Table 3.6) (Office for Budget Responsibility)

The OBR are forecasting that household spending will fall in real terms in 2011 by 1.1 per cent and grow by only 0.2 per cent in 2012. This is not good news for retailers nor, of course, for the economy. The drag on consumer spending growth is largely attributed to expected falls in real disposable (after-tax) incomes in both 2011 and 2012. In 2011, the household sector’s real income is forecast to decline by 2.3 per cent and then by a further 0.3 per cent in 2012.

The OBR’s figures on spending growth critically depend on the ability of households to absorb the negative shock to their real income. Empirical evidence tends to show that household spending growth is less variable than that in income and that households try and smooth, if they can, their spending. This means that the marginal propensity of households to consume out of changes to their income is below 1 in the short-run. In fact, the shorter the period of time over which we analyse income and consumption changes the smaller the consumption responses become. This is consistent with the idea that households are consumption-smoothers disliking excessively volatile spending patterns. In other words, the size of our monthly shop will usually vary less than any changes in our real income.

Of course, consumption-smoothing cannot be taken for granted. Households need the means to be able to smooth their spending given volatile and, in the current context, declining real incomes. Some economic theorists point to the importance of the financial system in enabling households to smooth their spending. In effect, households move their resources across time so that their current spending is not constrained solely by the income available to them in the current time period. This could mean in the face of falling real income perhaps borrowing against future incomes (moving forward in time expected incomes) or drawing down past savings.

The ability of households to move future incomes forward to the present has probably been impaired by the financial crisis. Banks are inevitably less cautious in their lending and therefore households are unable to borrow as much and so consume large amounts of future income today. In other words, households are credit-constrained. Furthermore, it is likely that households are somewhat uneasy about borrowing in the current climate, certainly any substantial amounts. Uncertainty tends to increase the stock of net worth a household would like to hold. A household’s net worth is the value of its stock of physical assets (largely housing wealth) and financial assets (savings) less its financial liabilities (debt). If households feel the need for a larger buffer stock of wealth to act as a sort of security blanket, they will not rush to acquire more debt (even if they could) or to draw down their savings.

The impairment of the financial system and the need for a buffer stock are two impediments to households smoothing their spending. They tend to make consumption more sensitive to income changes and so with falling incomes make it more likely that consumption will fall too. There are other related concerns too about the ability and willingness of consumers to smooth spending. Uncertainty arising from the volatility of the financial markets imposes liquidity constraints because households become less sure about the value of those savings products linked to the performance of equity markets. Consequently, they become less certain about the money (liquidity) that could be raised by cashing-in such products and so are more cautious about spending. Similarly, the falls in house prices have reduced the ability of households to extract housing equity to support spending. Indeed, with fewer transactions in the housing market the household sector is extracting less housing equity because it has been quite common, at least in the past, for households to over-borrow when moving and use the excess money borrowed to fund spending.

In short, there are many reasons to be cautious about the prospects for household spending. The expected decline in real income again in 2012 will ‘hit’ consumer spending. The question is how big this ‘hit’ will be and crucially on the extent to which households will be able to absorb it and keep spending.

Questions

  1. What do you understand by a consumption function? What variables would you include in such a function?
  2. Using the figures in the table in the text above, calculate ‘rough’ estimates of the income elasticity of consumption for each year. Why are these estimates only ‘rough’ approximations of the income elasticity of consumer spending?
  3. Draw up a list of factors that are likely to affect the strength of consumer spending in 2012. Explain how similar or different these factors are likely to have been to those that may affect spending during periods of strong economic growth.
  4. Explain what you understand by the term consumption-smoothing. Explore how households can smooth their spending and the factors that are likely to both help and prevent them from doing so.
  5. What do you understand by the net worth of housholds? Try drawing up a list of factors that could affect the net worth of households and then analyse how they might affect consumer spending.
