With countries around the globe struggling to recover from recession, many seem to believe that the answer lies in a growth in exports. But how can this be achieved? A simple solution is to lower the exchange rate.

Under a pegged exchange rate, the currency could be devalued. Alternatively, if the country’s inflation is lower than that of other countries, merely leaving the exchange rate pegged at its current level will bring about a real devaluation (in purchasing-power parity terms).

Under a floating exchange rate, one answer would be to lower interest rates. This would involve open market operations to support the lower rate and that would increase the money supply. But with central banks’ interest rates at virtually zero, it is not possible to lower them further. In such circumstances a solution would be a deliberate policy of increasing the money supply through “quantitative easing”. For example, the USA is considering a second round of quantitative easing (known as “QE2”). This would tend to push down the exchange rate of the dollar.

But stimulating exports through devaluation or depreciation is a zero-sum game globally. If currency A depreciates against currency B, currency B necessarily appreciates against currency A. Country A’s gain in exports to Country B are an increase in imports for Country B. It is logically impossible for every currency in the world to depreciate! Yet depreciation is exactly the policy being pursued by countries such as Japan, South Korea and Taiwan, all of which have directly intervened in the currency markets to lower their exchange rates. And, in each case of course, other countries’ currencies have an equivalent appreciation against them.

Economists and politicians in the USA argue that the dollar is fundamentally over valued against the Chinese yuan (or ‘renminbi’ as it is sometimes called). They are calling on China to revalue by far more than the 2% increase since June 2010. But what if China refuses to do so? On 29 September the House of Representatives passed a bill giving the executive branch the authority to impose a wide range of tariffs on imports from China. The bill was passed with a huge majority of 348 to 79.

So is this the start of a trade war? Many in the USA argue that China is already waging such a war by giving subsidies to a wide range of exports. And that war is hotting up. China has just announced that it is imposing traiffs ranging from 50% to 104% on various poultry imports from the USA. And if it is a trade war, will there be any winners?

Questions

  1. Why are competitive devaluations globally a zero sum game while global trade wars are a negative sum game?
  2. What are the arguments for and against using tariffs as a means of stimulating recovery?
  3. Why has quantitative easing so far had a more discernible effect on asset prices than on the real economy?
  4. Do a search on “Smoot-Hawley Tariff Act” of 1930 and describe its impact on the global economy in the 1930s. Are there any parallels today?
  5. How is it possible for massive trade surpluses and deficits to persist and yet for individual countries’ exchange rates and overall balance of payments to be in equilibrium?
  6. Are global trade imbalances widening, and if so why?
  7. What would determine the size of the effect on the US balance of trade of an appreciation of the yuan?

With the world economy in recession, major exporting countries are suffering more than many, especially exporters of high-quality manufactured products, many of which have a high income elasticity of demand. Germany, the world’s largest exporter, has been particularly hard hit. In the year to April 2009, the value of German exports fell by 28.7 per cent. The following articles look at the data and some of the explanations.

Questions

  1. Why have German exports fallen considerably more than German GDP? How can the accelerator theory help to explain the fall in German exports?
  2. If economic sentiment recovers in Germany, how will this affect (a) aggregate demand; (b) imports; (c) exports?
  3. Find out what has happened to the euro exchange rate index and assess whether movements in the euro have contributed to Germany’s export performance (see for example the Bank of England Statistical Interactive Database).

The World Economic Forum has warned that 2009 may see a ‘hard landing’ for China. In the context of China, this does not necessarily mean a recession, but the WEF report does identify a significant possible slowdown in Chinese growth. Given that high growth in China has led to a high level of demand for imports from other countries, especailly for raw materials and semi-finished goods, any slowdown in Chinese economic growth may have significant repercussions in the rest of the world. Any hopes that China and the emerging economies may help the rest of the world through their recessions have been dashed by data showing that even exports from China have been falling in October and November 2008 by 2.2% and 2.8% respectively. This has meant that aggregate demand in China is falling and may cause further problems, not only for China, but for the whole world economy.

The November 2008 trade statistics have just been released and they show that the UK had the largest nominal trade deficit on record at £8.3 billion (up from 7.6 billion in October). This represents nearly 7 per cent of GDP, the highest since 1974.

The article below is an economic briefing from The Times, published to support the Bank of England’s Target 2.0 competition. It considers the importance of the exchange rate in determining the demand for imports and exports and therefore the impact that exchange rate changes are likely to have on aggregate demand.
