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.

Questions
- What are the benefits of free trade?
- 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?
Over the past three months oil prices have been falling. From the beginning of September to the end of November Brent Crude has fallen by 30.8%: from $101.2 to a four-year low of $70.0 per barrel (see chart below: click here for a PowerPoint). The fall in price has been the result of changes in demand and supply.
As the eurozone, Japan, South America and other parts of the world have struggled to recover, so the demand for oil has been depressed. But supply has continued to expand as the USA and Canada have increased shale oil production through fracking.
As far as OPEC is concerned, rather than cutting production, it decided at a meeting on 27 November to maintain the current target of 30 million barrels a day.
The videos and articles linked below look at these demand and supply factors and what is likely to happen to oil prices over the coming months.
They also look at the winners and losers. Although falling prices are likely in general to benefit oil importing countries and harm oil exporting ones, it is not as simple as that. The lower prices could help boost recovery and that could help to halt the oil price fall and be of benefit to the oil exporting countries. But if prices stay low for long enough, this could lower inflation and even cause deflation (in the sense of falling prices) in many countries. This, in turn, could dampen demand (see the blog post, Deflation danger). This is a particular problem in Japan and the eurozone.
Major oil importing developing countries, such as China and India, however, should see a boost to growth from the lower oil prices.
Some oil exporting countries will be harder hit than others. Russia, in particular, has been badly affected, especially as it is also suffering from the economic sanctions imposed by Western governments in response to the situation in Ukraine. The rouble has fallen by some 32% this year against the US dollar and nearly 23% in the past three months alone.
Then there are the environmental effects. Cheaper oil puts less pressure on companies and governments to invest in renewable sources of energy. And then there are the direct effects on the environment of fracking itself – something increasingly being debated in the UK as well as in the USA and Canada.

Since coming to office two years ago, Shinzo Abe’s government has been determined to revive the Japanese economy. The policy has involved ‘three arrows‘: expansionary fiscal policy, expansionary monetary policy and supply-side reforms. But figures just out show that the Japanese economy is back in recession. The economy shrank by 0.4% in quarter 3, having shrunk by 1.9% in quarter 2.
This has come as a huge disappointment for Mr Abe, who has staked his political reputation on escaping from deflation and achieving sustained economic growth. In response, he has called a general election to put a revised economic plan to the electorate.

The main cause of the reversal into recession has been an increase in the sales tax on all goods, which has dampened spending. The tax rise, planned by the previous government, was to help reduce the deficit and start tackling the huge public-sector debt, which, at over 230% of GDP, is by far the highest in the developed world. Another rise in sales tax is due in October 2015 – from 8% to 10%. Mr Abe hopes to cancel the rise and it is this that he may put to the electorate.
So what is the outlook for Japan? Will quarter 4 show economic growth, or will pessimism have set in? Will the Bank of Japan introduce even more quantitative easing, or will it wait for the latest increase in QE to take effect (see the blog post, All eased out: at least for the USA and UK)?
The following articles look at the implications of the latest news, both for Japan and globally, and at the options for the government and central bank.

In two posts recently, we considered the pessimistic views of Robert Peston about the prospects for the global economy (see Cloudy skies ahead? and The end of growth in the West?). In this post we consider the views of Christine Lagarde, Managing Director of the International Monetary Fund, and Lord Adair Turner, the former head of the Financial Services Authority (FSA) (which was replaced in 2013 by the Financial Conduct Authority and the Prudential Regulation Authority).
Christine Lagarde was addressing an audience at Georgetown University in Washington DC. The first four links below are to webcasts of the full speech and subsequent interviews about the speech.
She gives a more gloomy assessment of the global economy than six months ago, especially the eurozone economy and several emerging economies, such as China. There are short- to medium-term dangers for the world economy from political conflicts, such as that between Russia and the West over Ukraine. But there are long-term dangers too. These come from the effects of subdued private investment and low infrastructure spending by governments.
Her views are backed up by the six-monthly World Economic Outlook, published by the IMF on 7 October. There are links below to two webcasts from the IMF discussing the report and the accompanying datasets.
In the final webcast link below, Lord Turner argues that there is a “real danger of a simultaneous slowdown producing a big setback to growth expectations.” He is particularly worried about China, which is experiencing an asset price bubble and slowing economic growth. Other emerging economies too are suffering from slowing growth. This poses real problems for developed countries, such as Germany, which are heavily reliant on their export sector.

At least once a year The Economist publishes its ‘hamburger standard’ exchange rates for currencies. It is a light-hearted attempt to see if currencies are exchanging at their purchasing-power parity rates. The test is the price at which a ‘Big Mac’ McDonald’s hamburger sells in different countries!
According to this simplified version of the purchasing-power parity theory, exchange rates should adjust so that a Big Mac costs the same in dollars everywhere (see Economics 8th edition Box 25.4).
These Big Mac exchange rates can be used to compare various prices and incomes between countries. The article linked below from The Guardian compares minimum wages between European countries in Big Mac terms.
There are 25 countries across Europe which have minimum wages. A clear pattern of minimum wage rates can be seen: although actual exchange rates understate the purchasing power of incomes in poorer European countries compared to richer ones, minimum wages, even in purchasing-power standard terms, are still higher in the richer countries.
Luxembourg’s minimum wage buys you just about three Big Macs in an hour, while most of northern Europe (and France) between 2–2.5 Big Macs. Moving south, the minimum wage nets about one Big Mac an hour. As we progress east, it begins to cost more than an hour of work on the minimum wage in order to afford a Big Mac.
Of course, there are other factors determining the dollar price of a Big Mac other than the failure of exchange rates to reflect purchasing-power parities. Nevertheless, using the Big Mac index in this way does give a useful preliminary snap shot of differences in what minimum wages can buy in different countries.
