The first link below is to an excellent article by Noriel Roubini, Professor of Economics at New York University’s Stern School of Business. Roubini was one of the few economists to predict the 2008 financial crisis and subsequent recession. In this article he looks at the current problem of substantial deficiency of demand: in other words, where actual output is well below potential output (a negative output gap). It is no wonder, he argues, that in these circumstances central banks around the world are using unconventional monetary policies, such as virtually zero interest rates and quantitative easing (QE).
He analyses the causes of deficiency of demand, citing banks having to repair their balance sheets, governments seeking to reduce their deficits, attempts by firms to cut costs, effects of previous investment in commodity production and rising inequality.
The second link is to an article about the prediction by the eminent fund manager, Crispin Odey, that central banks are running out of options and that the problem of over-supply will lead to a global slump and a stock market crash that will be ‘remembered in a hundred years’. Odey, like Roubini, successfully predicted the 2008 financial crisis. Today he argues that the looming ‘down cycle will cause a great deal of damage, precisely because it will happen despite the efforts of central banks to thwart it.’
I’m sorry to post this pessimistic blog and you can find other forecasters who argue that QE by the ECB will be just what is needed to stimulate economic growth in the eurozone and allow it to follow the USA and the UK into recovery. That’s the trouble with economic forecasting. Forecasts can vary enormously depending on assumptions about variables, such as future policy measures, consumer and business confidence, and political events that themselves are extremely hard to predict.
Will central banks continue to deploy QE if the global economy does falter? Will governments heed the advice of the IMF and others to ease up on deficit reduction and engage in a substantial programme of infrastructure investment? Who knows?

Questions
- Explain each of the types of unconventional monetary policy identified by Roubini.
- How has a policy of deleveraging by banks affected the impact of quantitative easing on aggregate demand?
- Assume you predict that global economic growth will increase over the next two years. What reasons might you give for your prediction?
- Why have most commodity prices fallen in recent months? (In the second half of 2014, the IMF all-commodity price index fell by 28%.)
- What is likely to be the impact of falling commodity prices on global demand?
- Some neo-liberal economists had predicted that central bank policies ‘would lead to hyperinflation, the US dollar’s collapse, sky-high gold prices, and the eventual demise of fiat currencies at the hands of digital krypto-currency counterparts’. Why, according to Roubini, did the ‘root of their error lie in their confusion of cause and effect’?
One thing that economists often argue for is free trade. It promotes competition, allows greater choice and generates efficiency gains through specialisation to name a few of the advantages. Barriers to trade have gradually been brought down across the global economy, but some do still exist.
Although free trade does have many advantages, there are also arguments for barriers to trade, especially for developing or emerging economies. In some cases, barriers to trade can help a country to develop a particular industry or offer protection to a new sector from the giants of the world. In the case of China, it had a quota system in place since 2009 to restrict exports of ‘rare earth materials’, such as Tungsten and Molybdenum. Many of the hi-tech products that China specialises in require these rare minerals during production and, as the dominant producer of these minerals, Beijing had imposed restrictions on exporting them in an attempt to develop these industries.
However, other countries had raised concerns about the quota system being used, suggesting that by restricting exports of rare earth minerals, China was driving up their price. It was also suggested that the restrictions benefited domestic producers, at the expense of foreign competitors, given that domestic producers were able to access the raw materials at cheaper prices.
A complaint was made to the World Trade Organization in March 2014 by the USA, supported by the EU, Canada and Japan. Following an investigation by a WTO panel, the panel found that China had failed to show sufficiently that the quotas were justified. After an appeal by China, the panel’s findings were upheld in August by the WTO.
In response to the failure of its appeal, China has just announced that it is removing the quotas on exports of rare earth materials. However, this is unlikely to be the end of the story, as other policies may well be imposed, including a resources tax; and an export licence is still required. The following articles consider this battle.

- Why do some countries choose to impose protectionist measures and what type of measures can be put in place?
- Using a diagram, explain the impact that export quotas would have on Chinese firms using these rare minerals and also on foreign firms.
- Why have other countries argued that export quotas push up prices of these minerals?
- What other policies might China put in place in order to protect its industries?
A big expenditure for many households is petrol. The price of petrol is affected by various factors, but the key determinant is what happens in the oil market. When oil prices rise, this pushes up the price of petrol at the pumps. But, when they fall, do petrol prices also fall? That is the question the government is asking.
The price of oil is a key cost of production for companies providing petrol and so when oil prices rise, it shifts the supply curve up to the left and hence prices begin to increase. We also see supply issues developing with political turmoil, fears of war and disruption and they have a similar effect. As such, it is unsurprising that petrol prices rise with concern of supply and rising costs. But, what happens when the opposite occurs? Oil prices have fallen significantly: by a quarter. Yet, prices at the pump have fallen by around 6%. This has caused anger amongst customers and the government is now urging petrol retailers to pass their cost savings from a lower price of oil onto customers. Danny Alexander, Chief Secretary to the Treasury said:
“I believe it’s called the rocket-and-feather effect. The public have a suspicion that when the price of oil rises, pump prices go up like a rocket. But when the price of oil falls, pump prices drift down like a feather … This has been investigated before and no conclusive evidence was found. But even if there were a suspicion it could be true this time it would be an outrage.”
However, critics suggest that tax policy is partly to blame as 63% of the cost of petrol is in the form taxation through fuel duty and VAT. Therefore even if oil prices do fall, the bulk of the price we pay at the pumps is made up of tax revenue for the government. Professor Stephen Glaister, director of the RAC Foundation said:
“It’s a simple story. Before tax we have just about the cheapest petrol and diesel in Europe. After tax we have just about the most expensive … It’s right to keep the pressure on fuel retailers but if drivers want to know what’s behind the high pump prices of recent years all they have to do is follow the trail back to the Treasury … if ministers are serious about reducing fuel prices further then they should cut duty further.”
(Click here for a PowerPoint of the chart.)
However, even taking out the fuel duty and VAT, Arthur Renshaw, an analyst at Experian has said that the actual price of petrol has fallen by 21% since last year. Still, a much bigger decrease than we have seen at the pumps. One further reason for this may be the fact that dollars is the currency in which oil is traded. The pound has been relatively weak, falling by almost 7% over the past few months and hence even though the price of oil has fallen, the effect on UK consumers has been less pronounced.
The big supermarkets have responded to government calls to cut petrol prices, but how much of this cut was influenced by the government and how much was influenced by the actions of the other supermarkets is another story. A typical oligopoly, where interdependence is key, price wars are a constant feature, so even if one supermarket cut petrol prices, this would force others to respond in kind. If such price wars continue, further price cuts may emerge. Furthermore, with oil production still at such high levels, this market may continue to put downward pressure on petrol prices. Certainly good news for consumers – we now just have to wait to see how long it lasts, with key oil producing countries, such as Russia taking a big hit. The following articles consider this story.

One of the key battle grounds at the next General Election is undoubtedly going to be immigration. A topic that is very closely related to EU membership and what can be done to limit the number of people coming to the UK. One side of the argument is that immigrants coming into the UK boost growth and add to the strength of the economy. The other side is that once in the UK, immigrants don’t move into work and end up taking more from the welfare state than they give to it through taxation.
A new report produced by University College London’s Centre for Research and Analysis of Migration has found that the effect on the UK economy of immigrants from the 10 countries that joined the EU from 2004 has been positive. In the years until 2011, it has been found that these immigrants contributed £4.96 billion more in taxes than they took out in benefits and use of public services. Christian Dustmann, one of the authors of this report said:
“Our new analysis draws a positive picture of the overall fiscal contribution made by recent immigrant cohorts, particularly of immigrants arriving from the EU … European immigrants, particularly, both from the new accession countries and the rest of the European Union, make the most substantial contributions … This is mainly down to their higher average labour market participation compared with natives and their lower receipt of welfare benefits.”
The report also found that in the 11 years to 2011, migrants from these 10 EU countries were 43 per cent less likely than native Britons to receive benefits or tax credits, and 7 per cent less likely to live in social housing. This type of data suggests a positive overall contribution from EU immigration. However, critics have said that it doesn’t paint an accurate picture. Sir Andrew Green, Chairman of Migration Watch commented on the choice of dates, saying:
“If you take all EU migration including those who arrived before 2001 what you find is this: you find by the end of the period they are making a negative contribution and increasingly so … And the reason is that if you take a group of people while they’re young fit and healthy they’re not going to be very expensive but if you take them over a longer period they will be.”
However, the report is not all positive about the effects of immigration. When considering the impact on the economy of migrants from outside of the EEA, the picture is quite different. Over the past 17 years, immigration has cost the UK economy approximately £120bn, through migrant’s greater consumption of public benefits, such as the NHS, compared to their contributions through taxation. The debate is likely to continue and this report will certainly be used by both sides of the argument as evidence that (a) no change in immigration policy is needed and (b) a major change is needed to immigration policy. The following articles consider this report.

Commodity prices have been falling for the past three years and have reached a four-year low. Since early 2011, the IMF overall commodity price index (based on 2005 prices) has fallen by 16.5%: from 210.1 in April 2011 to 175.4 in August 2014. The last time it was this low was December 2010.
Some commodity prices have fallen by greater percentages, and in other cases the fall has been only slight. But in the past few months the falls have been more pronounced across most commodities. The chart below illustrates these falls in the case of three commodity groups: (a) food and beverages, (b) agricultural raw materials and (c) metals, ores and minerals. (Click here for a PowerPoint of the chart.)
Commodity prices are determined by demand and supply, and factors on both the demand and supply sides have contributed to the falls.

With growth slowing in China and with zero growth in the eurozone, demand for commodities has shown little growth and in some cases has fallen as stockpiles have been reduced.
On the supply side, investment in mining has boosted the supply of minerals and good harvests in various parts of the world have boosted the supply of many agricultural commodities.
But in historical terms, prices are still relatively high. There was a huge surge in commodity prices in the period up to the financial crisis of 2008 and then another surge as the world economy began to recover from 2009–11. Nevertheless, taking a longer-term perspective still, commodity prices have risen in real terms since the 1960s, but with considerable fluctuations around this trend, reflecting demand and supply at the time.
