With the deepening euro crisis, the slide back into recession in many developed countries and the slowing down of fast-growing developing countries, such as China and India, confidence is waning.
But just as pessimism increases, so too does uncertainty. The global economy is getting more and more difficult to forecast. So should economists give up trying to forecast? Should we rely on guesswork and hunch, or looking into crystal balls?
Bank of England representatives have been appearing before the Treasury Select Committee. And they have reiterated the consensus that things are getting more difficult to forecast. As Mervyn King said in his evidence:
There is just enormous uncertainty out there. I have no idea what is going to happen in the euro area.
And this uncertainty is making people cautious, which, in turn, damages recovery. As Dr King went on to say:
There is no doubt that with the additional uncertainty this year there’s evidence of people behaving in a very defensive way, being unwilling to invest and of course the most extreme example of that would be if we were to get to a liquidity trap where essentially the main assets people wanted to hold were claims on the central bank.
Part of the reason for the uncertainty about global growth prospects is uncertainty about what European leaders will decide about the future of the eurozone. Another is uncertainty about how people will respond to the uncertainty of others. But predicting how others will predict is very difficult as they will themselves be predicting what others will predict. This dilemma was observed by Keynes when observing how investors on the stock market behaved, all trying to predict what others will do, and is known as the Keynesian Beauty Contest dilemma (see also).
So are governments and central banks powerless to counteract the uncertainty and pessimism? Can they restore confidence and growth? Members of the Bank of England’s Monetary Policy Committee believe that further action can be taken to stimulate aggregate demand. Further quantitative easing and cuts in interest rates could help as, according to Dr King, we are not yet in a liquidity trap.

Questions
- Why is it worth economists forecasting, even if those forecasts rarely turn out to be totally accurate?
- Why is it particularly difficult in current circumstances to forecast the state of the macroeconomy 12 months hence – let alone in two or three years?
- In what ways is the global macroeconomic situation deteriorating? What can national governments do about it?
- What limits the effectiveness of government action to deal with the current situation?
- What is meant by the liquidity trap? Are we close to being in such a situation today?
- Explain what is meant by the Keynesian Beauty Contest? How is this relevant today in explaining economic uncertainty and the difficulty of forecasting the economy?
A key economic principle is that rational decision making requires thinking at the margin. This involves a comparison of the additional (or marginal) benefits and costs of an activity.
An example of such rational behaviour would be deciding to drink one more beer or spending one more hour studying only if the additional benefits were greater than the additional costs. The optimum is where marginal benefit equals marginal cost.
And this applies to firms too. A firm maximises its profits by producing the output at which marginal revenue is equal to marginal cost.
However, a recent book by the American business guru Clayton Christensen argues that thinking in this way can be a problem. A recent article in the Guardian describes a story he tells of the time he refused to play for his university basketball team in a national final which took place on a Sunday and therefore conflicted with his religious beliefs. His decision involved sticking to his principles rather than thinking at the margin. For him, whilst the marginal cost of sacrificing these principles just once may well have been small compared to the resulting benefits, the eventual cost would be much higher.
Christensen also suggests that similar arguments can apply to firm decision making. The above article provides an example he uses of decisions made by executives at the Blockbuster video chain. When smaller rivals started offering movies by mail, Blockbuster instead continued to invest in its existing video store business model. This eventually proved disastrous for the company. The explanation given for this is that building on previous investments made more sense than setting up a mail-order arm which would cannibalise their existing business. On the other hand, an alternative explanation may be that executives at Blockbuster were irrationally allowing sunk costs to affect their decision making.

Questions
- Can you think of a situation where you have decided to stick to your principles rather than think at the margin?
- Why does a firm maximise profit by producing the output at which marginal revenue is equal to marginal cost?
- What do you think are the main costs of setting up a mail-order business?
- Are these costs mainly fixed or variable costs?
- Why is it irrational to take sunk costs into account when making a decision?
- Can you think of a situation where you have been influenced by sunk costs?
Will we soon live in a world without cash? More and more payments are being made electronically: whether by credit card or debit card, or by direct debit or bank transfer, or by cash loaded cards. For many people cash is now largely used only for small transactions.
But even here, things are changing. Direct transfers via mobile phone apps are increasingly being used for small transactions. Mobile phone companies, banks and others are busy developing such apps and more and more are being released onto the market.
And it’s not just in developed countries. Many developing countries are finding that mobile phones are an ideal way of transferring money for a whole range of transactions. For example, in Kenya, under 20% have a formal bank account, only 1% have a landline and yet more than 70% have a mobile phone, and this percentage is still rising. In 2007, a system known as M-Pesa (see also) was launched:
The user can create a free account and deposit money into it for free with registered agents at retail outlets. They may be gas stations, supermarkets, banks or micro-finance providers or small and medium-sized businesses. No minimum account balance is required.
The user can then transfer up to $440 from the account to someone else — including someone who doesn’t have a cellphone. The recipient provides identification and picks up the cash from another registered agent.
Users can deposit and withdraw cash, pay water and electricity bills, pay their children’s school fees, get paid by their employers or buy extra airtime for their phone.
Other developing countries are introducing similar systems. The second webcast link below gives an example from South Africa.
So how long will it be before cash disappears as a medium of exchange? Or will people continue to prefer to carry cash around with them – especially given the convenience of having cash machines readily available which do not charge for use.

Oil prices have been falling in recent months. By early June they had reached a 17-month low. The benchmark US crude price (the West Texas Intermediate price) fell to $83.2 at the beginning of the month, and Brent Crude (the North Sea reference price for refining into petrol) fell to $97.7 (see chart). (For a PowerPoint of the chart below, click here.)
At the same time various commodity prices have also been falling. The IMF all commodities price index has fallen by 7.2% over the past 12 months and by 6.2% in May alone. Some commodities have fallen much faster. In the 12 months to May 2012, natural gas fell by 44%, wheat by 25%, lamb by 37%, Arabica coffee by 36%, coconut oil by 45%, cotton by 47%, iron ore by 23% and tin by 29%.
Although part of the reason for the fall in the price of some commodities is increased supply, the main reason is weak world demand. And with continuing problems in the eurozone and a slowdown in China and the USA, commodity price weakness is likely to continue.
So is this good news? To the extent that commodity prices feed through into consumer prices and impact on the rate of inflation, then this is good news. As inflation falls, so central banks will be encouraged to make further cuts in interest rates (in the cases where they are not already at a minimum). For example, the Reserve Bank of Australia cut its cash rate last week from 3.75% to 3.5%. This follows on from a cut from 4.25% on 1 May. In cases where there is no further scope for interest rate cuts (e.g. the US Federal Reserve Bank, whose interest rate is between 0% and 0.25%), then the fall in inflation may encourage a further round of quantitative easing.
But falling commodity prices are also a reflection of bad news, namely the low economic growth of the world economy and fears of turmoil from a possible Greek exit from the euro.
Update
A day after this was written (9/6/12), a deal was agreed between eurozone ministers to provide support of up to €100 billion for Spanish banks. This helped to reduce pessimism about the world economy, at least temporarily. Stock markets rose and so too did oil prices, by around 1%. But if pessimism increases again, then the fall is likely to resume.

Here’s a question that goes to the heart of economics and the social sciences generally: how desirable is the market system?
Our lives are dominated by markets. Whether in working or consuming, we operate in a market economy in which money is exchanged for goods or services. But also financial and product markets determine much of the structure of society, where most things seem to have a price.
But whilst, as a positive statement, we can say that money and markets are all around us, does that make them desirable? Markets provide signals and incentives; but are the signals the right ones? What are the incentives and how do we respond to them? And are these responses optimal?
You will probably have studied various ways in which markets fail to provide the optimal allocation of resources. But what are the limits of markets as a mechanism for social choices? And is there some more fundamental issue about the morality of a society that is organised around markets?
These are questions considered in the following podcast. It is an episode from BBC Radio 4’s Start the Week programme, hosted by Andrew Marr, with guests Michael Sandel, Diane Coyle and Grigory Yavlinksy. Here are the programme details:
Andrew Marr discusses the relationship between markets and morals with the political philosopher Michael Sandel. In his latest book, What Money Can’t Buy, Sandel questions the dominance of the financial markets in our daily lives, in which everything has a price. But the economist Diane Coyle stands up for her much maligned profession, and points to the many benefits of a market economy. The Russian economist Grigory Yavlinksy argues against viewing the world of money as separate from culture and society: he believes the financial crisis was merely a symptom of a wider moral collapse, and that it is time to examine the way we live.

Questions
- What crises are there in current capitalism?
- What, according to Michael Sandel, is the difference between a market economy and a market society?
- Is the market society a relatively new phenomenon, or does it go back hundreds of years?
- To what extent is the greed expressed through markets and encouraged by markets affecting/infecting society and human relationships generally?
- What is the role of morality and trust in determining the desirability of market relationships?
- To what extent does a market economy allow people, rich and poor, to live separately from each other and not interact as joint members of society?
- What are the value systems promoted by marketisation? Should certain aspects of human life be outside these value systems?
- To what extent is the crisis of capitalism a crisis of economics?
- What policy alternatives are there for rebalancing society?
- What is the role of economists in advising on policy alternatives?
And this uncertainty is making people cautious, which, in turn, damages recovery. As Dr King went on to say:
