The new Japanese government under Shinzo Abe, which took office on 26 December 2012, has been pursuing a policy of weakening the yen. Using a combination of low interest rates, quantitative easing, expansionary fiscal policy and a declared aim of depreciation, the government has succeeded in driving down the value of the yen.
Since mid-November last year, the yen has depreciated by 28% against the dollar, 30% against the euro and 21% against sterling. The effective exchange rate index has fallen by 22% (see first diagram below: click here for a PowerPoint of the diagram).
But will this depreciation succeed in stimulating the Japanese economy and will it improve the balance of trade? The hope is that the falling yen will boost export sales by making them cheaper abroad, and will reduce the demand for imports by making them more expensive in Japan. The balance of trade will thereby improve and higher exports (an injection) and lower imports (a withdrawal) will stimulate aggregate demand and economic growth.
Traditionally Japan has run balance of trade surpluses, but since July 2012, it has been running monthly deficits – the longest run of deficits since 1980. But depreciation cannot be expected to turn this position around immediately. Indeed, theory suggests that the balance of trade is likely to deteriorate before it improves. This is known as the J-curve effect and is illustrated in the second diagram below. As page 768 of Economics, 8th edition states:
At first a devaluation or depreciation might make a current account deficit worse: the J-curve effect. The price elasticities of demand for imports and exports may be low in the short run (see Case Study 25.1 in MyEconLab). Directly after devaluation or depreciation, few extra exports may be sold, and more will have to be paid for imports that do not have immediate substitutes. There is thus an initial deterioration in the balance of trade before it eventually improves. In Figure 25.12 [the second diagram], devaluation takes place at time t1. As you can see, the diagram has a J shape.
Evidence suggests that the first part of the ‘J’ has been experienced in Japan: Japan’s balance of trade has deteriorated. But there is debate over whether the balance of trade will now start to improve. As the article by James Saft states:
But a look at the actual data shows Japanese companies, like British ones during a similar bout of currency weakness in 2008, appear to be more eager to use a newly competitive currency to pad profits through higher margins rather than higher export volumes. Thus far, Japanese exporters appear to be doing just that. Despite yen falls the price of Japanese exports in local currency has barely budged.
“Japanese companies have not actually cut the foreign currency prices of their exports. Just as with the UK exporters, the Japanese have chosen to hold foreign prices constant, maintain market share, and increase the yen value and thus the yen profit associated with yen depreciation,” UBS economist Paul Donovan writes in a note to clients.
The extra profits earned by Japanese companies from export sales may be stockpiled or paid out in dividends rather than reinvested. And what investment does take place may be abroad rather than in Japan. The net effect may be very little stimulus to the Japanese economy.
As stated by Saft above, the UK had a similar experience in the period 2007–9, when sterling depreciated some 27% (see the second diagram). The balance of trade improved very little and UK companies generally priced goods to markets abroad rather than cutting overseas prices.
But times were different then. The world was plunging into recession. Now global markets are mildly growing or static. Nevertheless, there is a danger that the upward slope of the J-curve in Japan may be pretty flat.

A simple model in economics is that of demand and supply. Through the price mechanism, signals are sent between consumers and producers and this interaction results in an equilibrium market price and quantity. However, what happens when the market for a good or service is in disequilibrium?
When a market is in equilibrium, demand equals supply. However, as we discussed in a previous blog concerning baby milk in China (see Milking the economy), markets are not always in equilibrium. If demand exceeds supply, a shortage will emerge and to eliminate this, the price must rise. If, on the other hand, supply exceeds demand, there will be an excess supply and thus the price must fall to restore equilibrium.
The market in question here is toilet paper in Venezuela! A severe shortage of this product has emerged in recent months, with shops running out of supplies. In a bid to relieve this shortage, the country’s Minister of Commerce has received approval for a $79 million credit, which can be used to import this basic product in short supply. Fifty million rolls will be imported to help fill the shortage that has emerged. The shortage is not just a problem for toilet paper, but also across a range of basic consumer goods. The article from Reuters comments that:
The government says the toilet paper shortages, like others, are the results of panicked buying and unscrupulous merchants hoarding the goods to artificially inflate prices.
Opposition critics say the problem is caused by the currency controls, created a decade ago by late socialist leader Hugo Chavez, and years of nationalizations that weakened private industry and left businesses unwilling to invest.
With shortages across a variety of products, the President has begun to work closely with business leaders to address this situation. The following articles consider this basic market, the intervention and consequences.

Questions
- Using a demand and supply diagram, explain how equilibrium is determined in a free market.
- Illustrate the shortage described in the aticles on your above demand and supply diagram. How should the price mechanism adjust?
- What types of government intervention have led to the shortages of such basic consumer goods?
- How have currency controls created a problem for Venezuela?
- With an increase in imported products, what impact might there be on Venezuela’s exchange rate and on its balance of payments?
The US dollar has been used as the international currency for the majority of international trade. Around 85% of foreign-exchange transactions are trades between US dollars and other currencies. As the first article below, from the Wall St Journal, states:
When a South Korean wine wholesaler wants to import Chilean cabernet, the Korean importer buys US dollars, not pesos, with which to pay the Chilean exporter. Indeed, the dollar is virtually the exclusive vehicle for foreign-exchange transactions between Chile and Korea, despite the fact that less than 20% of the merchandise trade of both countries is with the US.
… The dollar is the currency of denomination of half of all international debt securities. More than 60% of the foreign reserves of central banks and governments are in dollars.
But things are gradually changing as countries increasingly by-pass the dollar. Several countries have reached agreements with China to allow companies to exchange their currencies directly in so-called ‘currency swap‘ arrangements (see also). These include Japan, Australia, the UK, France/the eurozone, Argentina, Brazil, South Korea, Chile and Russia. But while these currency swap arrangements apply to current account transactions, there are still considerable controls of currency movements on China’s capital and financial accounts.
So what will be the implications for the USA and for China? What will be the impact on currency and bonds markets? The following articles explore the issues.

When you hear about China, it’s often regarding their huge population, their strong growth or their dominance in exports. But, when it comes to baby milk, China is certainly an importer – and a big one at that. For many new parents, getting the ‘real thing’ when it comes to baby formula is absolutely essential.
Chinese baby formula is feared by many new parents, due to the potential for it to contain hormones and dangerous chemicals. This has led them to go to great lengths to ensure they have sufficient supplies of imported baby formula, often only trusting it if it has been hand carried from overseas. However, such is the demand for this safe version of baby milk that the global response has been to place restrictions on it. Essentially, we are seeing a system of rationing emerging.

Hong Kong was the first government to limit the amount bought to two cans of formula per day, with the potential for a fine of over $64,000 and up to two years in prison for those who do not abide by the rules. The UK has now also responded with restrictions on the quantity that can be purchased and other countries may follow suit if the excess demand continues.
According to Sainsburys:
As a short-term measure, retailers including Sainsbury’s are limiting the amount of baby milk powder that people can buy. In this way we aim to ensure a constant supply for our customers and we therefore hope they won’t be inconvenienced.
The Chinese government has reacted to this and is aiming to restore confidence in the food industry, but as yet there has been little positive effect and until there are 100% guarantees of food safety the surge in demand for baby formula from abroad is likely to continue.
This policy of rationing is clearly not only going to affect Chinese parents looking to import baby formula, but is already having an impact on domestic residents. Parents living in the UK are feeling the rationing effects and are also being restricted in terms of how many cans of formula they can buy per day. For many families this isn’t a problem, but for those with multiple children and for whom a trip to the supermarket is not a simple task, the restrictions on baby milk purchases is likely to become a problem.

In the blog No accounting for trade, the rise in the UK’s balance of trade deficit was discussed. Many factors have contributed to this weakening position and no one market is to blame. But, by analysing one product and thinking about the factors that have caused its export volumes to decline, we can begin to create a picture not just of the UK economy (or more particularly Scotland!), but of the wider global economy.
Scotch whisky may not have been the drink of choice for many British adults, but look outside Great Britain and the volume consumed is quite staggering. For example, French consumers drink more Scotch whisky in one month than they drink cognac in one year. The volume of Scotch whisky exported from our shores was £4.23 billion for 2011, accounting for 90% of all sales and making its way into 200 markets. However, one problem with this product is that it is highly susceptible to the business cycle. Add to this the time required to produce the perfect Scotch (in particular the fact that it must be left to mature) and we have a market where forecasting is a nightmare.
Producers typically look to forecast demand some 10 years ahead and so getting it right is not always easy, especially when the global economy declines following a financial crisis! So what has been the impact on exports of this luxurious drink? In the past few years, it has been as key growth market for UK exports rising by 190% in value over the past decade. But in 2012 the volume of Scotch whisky exports fell by 5% to 1.19 billion bottles. What explains the decline in sales?
The biggest importer of Scotch whisky is France and its volumes were down by 25%. Part of this decline is undoubtedly the economic situation. When incomes decline, demand for normal goods also falls. Many would suggest Scotch whisky is a luxury and thus we would expect to see a relatively large decline following any given fall in income. However, another factor adding to this decline in 2012 is the increased whisky tax imposed by the French government. Rising by 15% in 2012, commentators suggest that this caused imports of Scotch whisky to rise in 2011 to avoid this tax, thus imports in 2012 took a dive. Spain is another key export market and its economic troubles are clearly a crucial factor in explaining their 20% drop in volume of Scotch whisky imported.
But, it’s not all bad news: sales to Western Europe may be down, but Eastern Europe and other growth countries/continents, such as the BRICs and Africa have developed a taste for this iconic product. Latvia and Estonia’s value of Scotch whisky imports were up by 48% and 28% respectively, as Russian demand rises and China, still growing, is another key market. Gavin Hewitt, chief executive of the Scotch Whisky Association said:
A combination of successful trade negotations, excellent marketing by producers, growing demand from mature markets, particularly the USA, and the growing middle class in emerging economies helped exports hit a record £4.3bn last year.
Furthermore, while the volume of exports worldwide did fall, the value of these exports rose to £4.27 billion, a growth of 1%. This suggests that although we are exporting fewer bottles, the bottles that we are exporting are more expensive ones. Clearly some people have not felt the impact of the recession. For Scotland and the wider UK, these declining figures are concerning, but given the cyclical nature of the demand, as the world economy slowly begins to recover, sales are likely to follow suit. Gavin Hewitt continued his comments above, saying:
We are contributing massively to the Government’s wish for an export-led recovery. There is confidence in the future of the industry, illustrated by the £2bn capital investment that Scotch whisky producers have committed over the next three to four years.
