Periodically, the BBC hosts debates on major global topics. The following links are to the January 2011 debate on the state of the world economy and on what policies governments and central banks should pursue.
Should governments be boosting aggregate demand by raising government expenditure and cutting taxes in order to stimulate growth and plan to bring down deficits over the long term once growth is established? Or should they embark on tough fiscal consolidation now by cutting government expenditure and/or raising taxes in order to stimulate confidence by international financiers, thereby keeping long-term interest rates down and creating the foundations for sustainable economic growth? The debate considers these two very different policy approaches.
The participants in the debate are Joseph Stiglitz (Professor of Economics, Columbia University), Christina Romer (Professor of Economics, University of California, Berkeley and Adviser to Barack Obama (2009–10)), George Papaconstantinou (Finance Minister of Greece), Dominique Strauss-Khan (Managing Director, IMF) and Zhou Xiaochuan (Governor, Chinese Central Bank). The debate is in five separate webcasts.

BP has just published its latest projection of energy trends – its Energy Outlook 2030. According to the press release:
World energy growth over the next twenty years is expected to be dominated by emerging economies such as China, India, Russia and Brazil while improvements in energy efficiency measures are set to accelerate.
The following podcast from the Financial Times features a discussion of the report and the factors affecting oil prices and their relationship to economic growth

The recession caused a large rise in unemployment in many countries. In the USA the rise has been particularly steep, where unemployment now stands at 14.5 million, or 9.8% of the labour force. Unemployment has continued to rise despite renewed growth in the US economy, where the latest annual real GDP growth is 2.6% (measured in Q3 2010). The rise in unemployment has been blamed on ‘sticky wages’ – i.e. the reluctance of wage rates to fall.
But are wages genuinely sticky as far as the average worker is concerned? They may be in many specific jobs with specific employers, but many workers made redundant then find work in different jobs at lower rates of pay. For them, their wage has fallen, even if particular jobs are paying the same as before.
So what are the consequences of this? Does the willingness of workers to accept lower paid jobs mean that the labour market is flexible and that people will thus price themselves into work? If so, why is employment still rising? Or does a reduction in real wages for many people dampen spending and hence aggregate demand, thereby reducing the demand for labour? If so, why is GDP rising?
The following articles look at the apparent stickiness of wages and the implications for the labour market and the macroeconomy.

Questions
- Why might nominal wages be sticky downwards in specific jobs in specific companies?
- Why might nominal average wages in the economy not be sticky downwards?
- Why is unemployment rising in the USA?
- Why might there be a problem of hysteresis in the USA that provides an explanation of the reluctance of unemployment to fall?
- Why might a fall in wages end up being contractionary?
- What lessons can be learned from the Great Depression about cures for unemployment?
- How might unemployment be brought down in the USA?
- Why may making wages somewhat more flexible, as opposed to perfectly flexible, not be a good thing?
One of the interesting things about the recent recession was the dilemma that it posed for governments. As aggregate demand fell, unemployment rose, incomes fell, which reduced demand further and so national output began to decline. Obviously there were many other factors contributing to this decline, in particular the housing market, but the long and the short of it is, aggregate demand was falling. With the AD curve shifting inwards, we would expect the average price level to fall at the same time: i.e. inflation doesn’t tend to be much of a problem during a recession. It is this fact that posed something of a dilemma. In the recession, not only was aggregate demand low, but inflation was rising. The explanation for this: in large part due to rising commodity prices – a supply-side shock. Governments had to deal with low national output and inflation: this combination made policy changes much more complex.
While prices for many goods and commodities did fall significantly after their peak in 2008, there has been a gradual rise again and there seems to be no end in sight. Headline food prices, in particular, have increased almost to their 2008 levels, although in real terms prices are still lower. Onions in India; cabbage, pork and mackerel in South Korea; chillies in Indonesia – the list goes on. The rapidly rising prices of these basic foodstuffs has, in many cases, led to emergency government intervention. However, there are fewer concerns this time round, as many hope that the causes of these higher prices are not just the increases in demand but crucially temporary supply shocks. Bloomberg’s Businessweek Assistant Managing Editor, Sheelah Kolhatkar, said:
There are a lot of reasons [for rising prices]. Weather is cited as a big one. There’s been sort of freak weather in different parts of the world. Russia experienced a drought. There are floods in Australia. There’s been sort of freezing weather in Florida. Our own Midwest experienced flooding earlier this year. And because the market for a lot of these food commodities is global, when something strange happens somewhere, that can affect a crop.
On the other hand, there are growing concerns at the timing of this inflation: the developed world has barely escaped from recession. How is it that inflation can already be a problem? Furthermore, with loose monetary policy in many countries, rising food and commodity prices could continue for some time.
An interesting question to consider is which countries will be affected the most? In Britain, like other developed countries, food consumption accounts for between 15 and 20 per cent of a household budget. However, in developing countries, food can take up between 50 and 75 per cent of a houshold budget, so any rise in food prices is disastrous.
What does it mean for the recovery? Well, if food (a necessity) is increasing in price, households have little choice but to pay the higher prices. This means they have less disposable income for other goods, hence aggregate demand may be adversely affected. The following articles will hopefully give you some ‘food for thought’!

For most people, buying a new car is a luxury and in times of hardship it is a luxury that many cannot afford. Sales of new cars did grow during 2010 by 1.8% compared to the previous year, although the end of the car scrappage scheme in March 2010 did see a fall in sales. Sales went from being 19.9 per cent up on 2009 in the first half of the year, to being 13.8 per cent down for the remainder of 2010. On top of this, they are predicted to fall by some 5% over the coming 12 months.
Part of the explanation of this trend is the VAT rise. While an extra 2.5% is hardly noticeable on many every day items (as we saw when VAT was reduced to 15%), it will have a much larger effect on more expensive items, such as cars.
It was expected that people thinking of buying a new car would try to beat the VAT rise and so car firms hoped for a surge in sales during December. However, this did not occur and with VAT at 20% during 2011, car prices will rise: a £15,000 car will cost an extra £320. Another contributing factor to the lower than expected sales in December was the snow. Retail sales in December collapsed by 37.5%, where as fleet sales, which are less likely to be affected by the adverse weather rose by 5.1%. Similar patterns were seen in Spain, Italy and France, but in Germany sales were up by 7% on the year from December 2009.
The good news for the UK car industry is that the second half of 2011 is expected to see growth, so there may be some recovery. Furthermore, UK-built cars have seen a rise in sales – up by 17%. Finally, as petrol prices continue to rise, it is hoped that this might encourage people to trade in their less efficient old cars for more fuel-efficient new cars. This will certainly be an industry to watch over the next few months.
