Keynes referred to the ‘paradox of thrift’ (see, for example, Box 17.5 on page 492 of Sloman and Wride, Economics, 7th edition). The paradox goes something like this: if individuals save more, they will increase their consumption possibilities in the future. If society saves more, however, this may reduce its future income and consumption. Why should this be so? Well, as people in general save more, they will spend less. Firms will thus produce less. What is more, the lower consumption will discourage firms from investing. Thus, through both the multiplier and the accelerator, GDP will fall.

What we have in the paradox of thrift is an example of the ‘fallacy of composition’ (see Sloman and Wride, Box 3.7 on page 84). What applies at the individual level will not necessarily apply at the aggregate level. The paradox of thrift applied in the Great Depression of the 1930s. People cutting back on consumption drove the world economy further into depression.

Turn the clock forward some 80 years. On 26/27 June 2010, leaders of the G20 countries met in Canada to consider, amongst other things, how to protect the global economic recovery while tackling the large public-sector deficits. These deficits have soared as a result of two things: (a) the recession of 2008/9, which reduced tax revenues and resulted in more people claiming benefits, (b) the expansionary fiscal policies adopted to bring countries out of recession.

But the leaders were divided on how much to cut now. Some, such as the new Coalition government in the UK, want to cut the deficit quickly in order to appease markets and avert a Greek-style crisis and a lack of confidence in the government’s ability to service the debt. Others, such as the Obama Administration in the USA, want to cut more slowly so as not to put the recovery in jeopardy. Nevertheless, cuts were generally agreed, although agreement about the timing was more vague.

So where is the fallacy of composition? If one country cuts, then it is possible that increased demand from other countries could drive recovery. If all countries cut, however, the world may go back into recession. What applies to one country, therefore, may not apply to the world as a whole.

Let’s look at this in a bit more detail and consider the individual elements of aggregate demand. If there are to be cuts in government expenditure, then there has to be a corresponding increase in aggregate demand elsewhere, if growth is to be maintained. This could come from increased consumption. But, with higher taxes and many people saving more (or reducing their borrowing) for fear of being made redundant or, at least, of having a cut in their incomes, there seems to be little sign that consumption will be the driver of growth.

Then there is investment. But, fearing a ‘double-dip recession’, business confidence is plummeting (see) and firms are likely to be increasingly reluctant to invest. Indeed, after the G20 summit, stock markets around the world fell. On 29 June, the FTSE 100 fell by 3.10% and the main German and French stock market indices, the Dax and the Cac 40, fell by 3.33% and 4.01% respectively. This was partly because of worries about re-financing the debts of various European countries, but it was partly because of fears about recovery stalling.

The problem is that cuts in government expenditure and rises in taxes directly affect the private sector. If government capital expenditure is cut, this will directly affect the construction industry. Even if the government makes simple efficiency savings, such as reducing the consumption of paper clips or paper, this will directly affect the private stationery industry. If taxes are raised, consumers are likely to buy less. Under these circumstances, no wonder many industries are reluctant to invest.

This leaves net exports (exports minus imports). Countries generally are hoping for a rise in exports as a way of maintaining aggregate demand. But here we have the fallacy of composition in its starkest form. If one country exports more, then this can boost its aggregate demand. But if all countries in total are to export more, this can only be achieved if there is an equivalent increase in global imports: after all, someone has to buy the exports! And again, with growth faltering, the global demand for imports is likely to fall, or at best slow down.

The following articles consider the compatibility of cuts and growth. Is there a ‘paradox of cuts’ equivalent to the paradox of thrift?

The annual Agricultural Outlook for the next ten years has just been published jointly by the OECD and the UN Food and Agriculture Organization (FAO). Click here and here for audio presentations of the report by the FAO’s Jacques Diouf and the OECD’s Angel Gurría.

The report argues that world recovery will raise agricultural prices. This will be partly the direct result of higher demand and partly the result of higher prices of agricultural inputs, such as fertilisers and fuel. But prices will not rise back to the peak levels of 2007/8. These higher prices, however, would have a positive effect on world food output, especially in the BRICs (Brazil, Russia, India and China). This, in turn, would limit the price rises.

So is this good news for food producers and consumers? The following articles look at the issues

  2. Represent the analysis on a supply and demand diagram (or diagrams).
  3. What is the relevance of (a) income elasticity of demand, (b) price elasticity of demand, (c) cross-price elasticity of demand, (d) price elasticity of supply, in explaining the likely future movements of food prices and why some food prices are likely to rise faster than others?

As one of his first acts, the new UK Coalition government’s Chancellor, George Osborne, set up an independent Office for Budget Responsibility (OBR) (see Nipping it in the Budd: Enhancing fiscal credibility?. The role of the OBR is to provide forecasts of the economy and the data on which to base fiscal policy.

On 14 June, the OBR produced its first forecast in time for the Budget scheduled for 22 June. It has some bad news and some good news. First the bad news: it forecasts that growth for 2011 will be 2.6% – down from the 3–3.5% forecast by Labour in its last Budget in March. But now the good: it forecasts that the public-sector deficit in 2010/11 will be 10.5% of GDP – down from the 11.1% forecast by Labour; and that public-sector debt will be 62.2%, not the 63.6% forecast by Labour. These forecasts are before any policy changes announced in the Budget on 22 June.

Meanwhile, the accountants BDO have published a survey of business confidence. This shows the largest drop since the survey began. Talk by the government of cuts and worries that this will impact directly on the private sector have caused many businesses to cut investment plans. The worries are compounded by fears of a decline in export demand as countries abroad also make cuts.

So what does the future hold? Should we put any faith in forecasts? And should we be more worried about a double-dip recession or by failure to make sufficient inroads to deficits to calm markets?

Questions

  1. How reliable is the OBR’s forecast likely to be? What factors could cause the forecast for economic growth to be (a) an overestimate; (b) an underestimate?
  2. What is likely to happen to aggregate demand over the coming months? Explain.
  3. What is meant by the ‘structural deficit’. Why might the structural deficit fall as the economy recovers? Would you explain this in terms of a shift or a movement along the short-term aggregate supply curve?
  4. Which is the greatest threat over the long term: inflation or deflation?
  5. Do you agree that the debate about cutting the deficit is merely a question of timing, not of the amount to cut?
  6. Why may policies of fiscal tightening, if carried out generally around the world, involve the fallacy of composition?
  7. Is there any common ground between the fiscal ‘hawks’ and fiscal ‘doves’ (see the last Guardian article above)?

In 2008 and 2009, as the global recession deepened, so governments around the world turned to Keynesian policies. Aggregate demand had to be boosted. This meant a combination of fiscal and monetary policies. Fiscal stimulus packages were adopted, combining increased government expenditure and cuts in taxes. On the monetary policy front, central banks cut interest rates to virtually zero and expanded the money supply in bouts of quantitative easing.

The global recession turned out not to be a deep as many had feared and the Keynesian policies were hailed by many as a success.

But how the tide is turning! The combination of the recession (which reduced tax revenues and increased welfare spending) and the stimulus packages played havoc with public finances. Deficits soared. These deficits had to be financed, and increasingly credit agencies and others were asking how sustainable such deficits were over the longer term. These worries have been compounded by the perilous state of the public finances in countries such as Greece, Portugal, Ireland and Hungary. The focus has thus turned to cuts. In fact there is now an international ‘competition’ as to which country can wear the hairiest hair shirt. The new Coalition government in the UK, for example, is busy preparing the general public for deep cuts to come.

We are now seeing a re-emergence of new classical views that increased deficits, far from stimulating the economy and resulting in faster growth, largely crowd out private expenditure. To prevent this crowding out and restore confidence in financial markets, deficits must be rapidly cut, thereby allowing finance to be diverted to the private sector.

But if the contribution to aggregate demand of the public sector is to be reduced, and if consumption, the largest component of aggregate demand, is also reduced as households try to reduce their reliance on borrowing, where is the necessary rise in aggregate demand to come from? We are left with investment and net exports – the remaining two components of aggregate demand, where AD = C + G + I + (X – M).

But will firms want to invest if deficit reduction results in higher taxes, higher unemployment and less spending by the government on construction, equipment and many other private-sector goods and services. Won’t firms, fearing a decline in consumer demand, and possibly a ‘double-dip recession’, hold off from investing? As for export growth, this depends very much on growth in the rest of the world. If the rest of the world is busy making cuts too, then export growth may be very limited.

The G20, meeting in Korea on 4 June, wrestled with this problem. But the mood had definitely turned. Leaders seemed much more concerned about deficit reduction than maintaining the fiscal stimulus.

The following articles look at the arguments between Keynesians and new classicists. The disagreements between their authors reflect the disagreements between economists and between politicians about the timing and extent of cuts.

As the news from the Gulf of Mexico goes from very bad to even worse, so BP is increasingly coming under the international spotlight for its approach to risk management and safety. Was it sufficiently cautious? Could the accident on April 20 that killed 11 men and has been gushing some 800,000 gallons per day of crude oil into the sea have been averted? When the consequences of a pipe rupture are so catastrophic, is ‘catastrophic risk’ appropriately priced? As Tony Hayward, BP’s Chief Executive, told the Financial Times (see links below): “It was ‘an entirely fair criticism’ to say the company had not been fully prepared for a deep-water oil leak.”

One insight into BP’s approach to risk has come to light with the leaking of a 2002 memo from BP on how human life ought to be valued in any cost–benefit analysis of a project. As the Chicagoist summarises the memo:

A two page document prepared by risk managers in 2002 titled “Cost benefit analysis of three little pigs” shows the type of thinking BP put into risk assessment. The memo shows, in cartoonish fashion, that blast resistant trailers for BP’s workers weren’t necessary, because the cost was too high. In 2005, a refinery caught fire, killing 15 and injuring 170 people.

So how should catastrophic risk be taken into account? What does a company do when the probability of a disaster is extremely low and yet the costs of such a disaster, were it to occur, are extremely high?
