Despite this argument there are a number of governments around the world who implement a cheap currency policy as a way of making their domestic goods and services more competitive in overseas markets. This lesson also compares the relationship between PED and the current account. </p><hr class="hidden" /><div class="blueBg"><h3>Enquiry question</h3><p>Why might a competitive devaluation may solve a long term current account deficit.

The condition states that a country will only benefit from a competitive devaluation if the PED of exports + PED of imports is greater than 1 (i.e PED elastic).</p><p><strong>J curve - </strong>the time path of a country's trade balance following a devaluation or depreciation of its currency, under a certain set of assumptions.</p></div><p> The activities on this page are available as a class handout at: <a href="/media/ib/economics/files/international-trade/marshall-lerner-condition.pdf" target="_blank" title="Student handouts"><img class="ico" src="https://assets.inthinking.net/thinkib/icons/student-handout.png" /> Marshall-Lerner condition / J curve</a></p><div class="pinkBg"><p><strong>Beginning exercise</strong></p><p>Some governments believe that a devaluation of a nation's currency will lead, after a short period of time, to an improvement in the current account - at least until the impact of inflation withers away at this advantage. However the following short video, from a Singaporean IB student explains why this may not always be the case. After watching the short video complete the work point which follows:</p><p style="text-align: center;"><iframe allowfullscreen="" frameborder="0" height="360" src="//www.youtube.com/embed/wz0nD6zf5PA" width="640"></iframe></p><p>Why might a devaluation of the Singaporean $ not improve the nation's trading position?</p></div><section class="tib-hiddenbox"><p><strong>Hint:</strong></p><p><span style="color:#FF0000;">The short presentation clearly states that many of the goods that Singapore imports consist of raw materials and essential items such as food and energy. These goods are likely to be price inelastic. This means that should the Singapore $ reduce in value then they will have to pay more Singapore $s for those items. Because these items are essentials the country will still be required to import them in roughly the same quantity as before - thus worsening their current account, not improving it.</span></p></section><div class="blueBg"><h4><strong>Activity 1: The relationship between PED and the current account - Marshall-Lerner condition</strong></h4><table border="3" cellpadding="0" cellspacing="0"><caption><p style="text-align: left;"><em>Complete the table showing the impact of PED on the current account:</em></p></caption><tbody><tr><td style="text-align: center;"><strong>Country</strong></td><td style="text-align: center;"><strong>PED of exports</strong></td><td style="text-align: center;"><strong>PED of imports</strong></td><td style="text-align: center;"><strong>Total PED</strong></td><td style="text-align: center;"><strong>Impact of a 10% devaluation on volume of exports</strong></td><td style="text-align: center;"><strong>Impact of a 10% devaluation on the volume of imports </strong></td><td style="text-align: center;"><strong>Total Impact on the current account</strong></td></tr><tr><td style="text-align: center;">A</td><td style="text-align: center;">0.3</td><td style="text-align: center;">0.2</td><td style="text-align: center;">0.5</td><td style="text-align: center;">3% rise</td><td style="text-align: center;">2% fall</td><td style="text-align: center;"><section class="tib-hiddenbox"><p><span style="color:#FF0000;">will worsen because the 5% rise in traded goods < 10% devaluation</span></p></section></td></tr><tr><td style="text-align: center;">B</td><td style="text-align: center;">0.7</td><td style="text-align: center;">0.8</td><td style="text-align: center;">1.5</td><td style="text-align: center;"><section class="tib-hiddenbox"><p><span style="color:#FF0000;">7% rise</span></p></section></td><td style="text-align: center;"><section class="tib-hiddenbox"><p><span style="color:#FF0000;">8 % fall</span></p></section></td><td style="text-align: center;"><section class="tib-hiddenbox"><p><span style="color:#FF0000;">will improve <span style="color:#FF0000;">because the 15% rise in traded goods >10% devaluation</span></span></p></section></td></tr><tr><td style="text-align: center;">C</td><td style="text-align: center;">0.5</td><td style="text-align: center;">0.5</td><td style="text-align: center;">1</td><td style="text-align: center;"><section class="tib-hiddenbox"><p><span style="color:#FF0000;">5% rise</span></p></section></td><td style="text-align: center;"><section class="tib-hiddenbox"><p><span style="color:#FF0000;">5 % fall</span></p></section></td><td style="text-align: center;"><section class="tib-hiddenbox"><p><span style="color:#FF0000;">will be unaffected by the devaluation</span></p></section></td></tr></tbody></table></div><section class="tib-hiddenbox"><p><span style="color:#FF0000;">To calculate this you need to multiple the size of the devaluation (10%) by the PED (0.7) </span></p></section><div class="blueBg"><h4><strong>Activity 2: Practise activities</strong></h4><p>The table includes the volume of exports and imports between two trading nations - Saudi Arabia and Japan.

Neither is their much change in the volume of overseas goods and services sold either. This is because domestic stores still have stock remaining unsold, which the wholesaler purchased at the existing exchange rate. Similarly shops overseas still have a stock of the nation's goods, purchased at the previous (higher) exchange rate. This means that in the short term, between points X and Y on the J curve, the fall in price of Turkish products will be greater than the change in demand.</span></p></section><p> (b) Why according to J curve theory does the current account improve between points Y and Z?</p><section class="tib-hiddenbox"><p><span style="color:#FF0000;">As the old stock is sold and new stock is purchased at the lower exchange rate, the nation's products gain in competitiveness. Customers (both domestically and in export markets) actively choose to purchase the nation's products and at point Y the combined elasticity of exports + imports rises above 1. At this point the current account improves and this point is represented by point Z on the diagram.</span></p></section><p>(c) Explain the likely change in the nation's current account beyond point Z. </p><section class="tib-hiddenbox"><p><span style="color:#FF0000;">Over time the nation will experience cost push inflationary, as the lower valued currency increases production costs and over time, we would expect the nation's current account to come under pressure once again.</span></p></section></div><div class="pinkBg"><h4><strong>Activity 7</strong></h4><p>In August 2015, Ruchir Sharma of Morgan Stanley warned that a number of governments were adopting a policy of 'competitive devaluations', which in turn could trigger a real recession'. </p><p>1. Why do some governments deliberately devalue their currency?</p><section class="tib-hiddenbox"><p><img alt="" height="149" src="/media/ib/economics/images/international-trade-2/devaluation_of_currency.jpg" style="float: left;" title="image: http://www.mbaskool.com/business-articles" width="387" /><span style="color:#FF0000;">A competitive devaluation (deliberately reducing the value of the national currency) is a way of improving the international competitiveness of a country. Reducing the price of a currency will make the products produced in their country relatively cheaper. The Marshall-Lerner condition states that if the combined PED of exports and imports is greater than 1 then this will improve the country's current account in the short term.</span></p><p><span style="color:#FF0000;">However a cheaper currency price will increase cost push inflation in the economy and over time this will erode the advantage caused by the competitive devaluation.</span></p></section><p>2. Why might a series of competitive devaluations trigger a global recession?</p><section class="tib-hiddenbox"><p><span style="color:#FF0000;"><img alt="" src="/media/ib/economics/images/general-2/pexels-photo-38091-medium.jpeg" style="width: 320px; height: 236px; float: right;" title="pexels.com" />The global recession of 2008 was made much worse because of a series of competitive devaluations, by a range of different central banks. One central bank after another devalued their currency in an attempt to increase exports and cut imports.</span></p><p><span style="color:#FF0000;">However, as each country reduced its imports this also reduced world export levels as well. This is because on a world level exports and imports must be equal. One countries current account surplus is anothers deficit. Therefore reduced imports meant reduced exports too, and, hence, reduced economic activity. The competitive devaluations drove economies further and further into a vicious spiral.</span></p></section></div><div class="pinkBg"><h4><strong>Activity 8: A focus on Turkey</strong></h4><p>The national currency of Turkey, the Turkish lira has, over a five year period, been one of the worst performing currencies. During this same period the current account deficit has barely improved.

During 2022-2023 the nation will have also been significantly impacted by higher food and energy prices following the Covid pandemic, with the nation an importer of both commodities.

Firstly according to J curve theory a cheaper national currency will have had little initial impact on the volume of goods and services traded. This is because shops in the UK would still have held stock remaining unsold which the wholesaler purchased at an existing exchange rate. Similarly shops overseas would still have had supplies of UK goods, purchased at the previous (higher) exchange rate. This might explain the rise in the current account deficit in the three months following the depreciation.</span></p><p><span style="color:#FF0000;">Only once new stock was purchased and consumers had to time to adjust to new prices would the impact of a cheaper £ be likely to have any direct impact on the UK's trading position. This might have been evident during the following 9 months, when the UK's current account deficit improved, albeit very slightly - significantly less than the 17% devaluation. </span></p><p><span style="color:#FF0000;"><em><strong>Why has the UK not seen a greater improvement in its current account?</strong></em></span></p><p><span style="color:#FF0000;">One obvious reason is that the UK tends to trade in goods and services with low PED elasticity, in the short term, particularly energy and raw materials. This is supported by the following table which shows that Britain's traded goods are highly inelastic in the short term while significantly more PED elastic in the long term. </span></p><table border="3" cellpadding="0" cellspacing="0" height="95" width="785"><tbody><tr><td style="text-align: center;"></td><td style="text-align: center;"><strong>SR elasticity of imports</strong></td><td style="text-align: center;"><strong>SR elasticity of exports</strong></td><td style="text-align: center;"><strong>LR elasticity of imports</strong></td><td style="text-align: center;"><strong>LR elasticity of exports</strong></td></tr><tr><td style="text-align: center;">United Kingdom</td><td style="text-align: center;">- 0</td><td style="text-align: center;">- 0.2</td><td style="text-align: center;">- 0.6</td><td style="text-align: center;">- 1.6</td></tr></tbody></table><p><span style="color:#FF0000;">In the long run, if the table above is to believed, the UK may eventually see a 27% rise in export volumes to match the 17% fall in currency value and a 10% fall in imports, again in the long term. In the short run, however, the PED of Britain's trade products is virtually zero. This means that the UK was always unlikely to see any significant change in the current account after just three months, as the article and current account figures testified.</span></p></section><div class="greenBg"><h4><strong>Activity 10: Link to the assessment - short paper two questions </strong></h4><p>(a) Use the Marshall-Lerner condition to explain how a change in exchange rates impacts on a nation's current account. <em>[4 marks]</em></p><section class="tib-hiddenbox"><div><p><span style="color:#FF0000;">According to the Marshall-Lerner condition, if the combined PED elasticity of a nation's exports and imports is less than one i.e. PED inelastic then a devaluation will not improve the current account. This is because the change in demand for exports / imported products will be proportionately lower than the size of the devaluation (the change in price of the currency). </span></p><p><span style="color:#FF0000;">However, in circumstances where the combined PED elasticity of imports and exports is greater than 1 (PED elastic) then the current account will improve, <span style="color:#FF0000;">because the change in demand for exports / imported products will be proportionately greater than the size of the devaluation (the change in price of the currency). </span></span></p></div></section><p>(b) Illustrate using a J curve why a currency devaluation might not be effective in improving a nation's current account. <em>[4 marks]</em></p><section class="tib-hiddenbox"><div><span style="color:#FF0000;"></span><p><span style="color:#FF0000;"><span style="color:#FF0000;"><img alt="" src="/media/ib/economics/images/international-trade/jcurve.png" style="width: 300px; height: 238px; float: left;" /></span>As the J curve illustrates, following a devaluation of any currency there will initially be little or no little change in the quantity demanded for domestic goods and services as the changing market conditions take time to have an impact on consumption. For example, shops are already well stocked with produce purchased at the previous exchange rate.</span></p><p><span style="color:#FF0000;">At point Y, however, providing the combined PED elasticity of imports and exports is greater than 1 the current account deficit will start to fall and may even go into surplus at point Z.</span></p><p><span style="color:#FF0000;">However, this improvement in competitiveness will erode over time due to rises in cost push inflation, making the nation's traded goods and services less competitive and cancelling out any advantage gained. </span></p></div></section></div><script>document.querySelectorAll('.tib-teacher-only').forEach(e => e.remove());</script>
