Productivity and the Current Account Deficit

Readers Question: Using the data and your own economic knowledge, evaluate the importance of rising productivity in bringing about an improvement in the UK balance of payment on the current account.

Productivity is defined as output per worker or output per input. Rising productivity implies that the economy is becoming more competitive and will be able to produce goods at a lower cost. If UK firms can produce goods at a lower cost this will make UK exports more competitive and therefore increase exports.

For example, if there is an improvement in labour productivity following better education and training, firms will be help to produce more for the same costs. This will help the UK compete and sell more exports.

Increasing exports will help improve the current account as exports will be rising relative to imports.

Essay on Supply Side Reforms and Appreciation

Readers Question: Assess the view that supply-side reforms have enabled the UK economy to be ‘more successful in maintaining growth, despite an appreciation in the value of its currency’ (Extract 1, lines 5-6}. (From Edexcel unit 3)

An appreciation in the exchange rate would tend to reduce aggregate Demand and lead to lower economic growth. An appreciation makes exports less competitive, decreasing quantity of exports. An appreciation also  makes imports cheaper, increasing quantity of imports (and hence money leaving the economy). Therefore, the (X-M) component of AD will be lower. This will reduce Economic growth.

Effects of Falling Exchange Rates

Readers Question: When exchange rate goes down, what positive thing can happen?

  • When there is a depreciation and the exchange rate goes down, the exports of a country will be cheaper and imports will become more expensive.
  • e.g. a depreciation of the dollar makes US exports more competitive.
  • Therefore there will be an increase in exports and decrease in quantity of imports. Therefore, domestic firms will benefit from increased sales. This may lead to job creation and lower unemployment, especially in exporting industries.
  • The increase in X-M will help increase AD and therefore lead to economic growth Continue reading →

Australian Dollar Appreciation

Readers Question: The Aussie dollar has appreciated strongly against the USD in recent times. Discuss the consequences of this rapid appreciation for Australia’s Balance of Payments?

The Australian Dollar has appreciated against the US Dollar because

  • Large US current account deficit
  • Australia has benefited from rising commodity prices, commodities which Australia produces a lot of.
  • US interest rates are lower than Australia and the US economy has been weakening.

April 2008 $1 Aus Dollar = US 0.9300

Effects of AUS Dollar Appreciation

  • It makes Australian exports more expensive. Therefore there will be a fall in demand for Australian exports.
  • Imports into Australia will become cheaper, therefore there will be an increase in demand for imports.
  • This is likely to worsen the current account deficit. However, this assumes that demand for exports and imports is relatively elastic. The Marshall Lerner condition states that if PED of exports + PED of imports > 1 then an appreciation will worsen the current account. Continue reading →

How Much Does a Current account deficit affect a Country?

Readers Question: A huge current account deficit can seriously affect the economic well being of any country, big or small. Discuss this statement and offer some policy advises to the governemnts in countries which suffer from this.

Please see: Does a current account deficit matter?

I would add that some countries are better able to finance a current account deficit. E.g. the US could run a current account deficit because Chinese investors were willing to buy US assets. US debt was bought at a relatively low interest rates because of the dollar’s status as the reserve currency.

Some countries like the UK, may be an attractive destination for long term investment (Capital inflows) and this makes a current account deficit easier to finance. So it does depend on the size of the country and also the confidence people have in investing their. E.g. a developing economy may find it more difficult to attract capital flows.

Visiting New York to Spend some Dollars

Tomorrow, Monday, I am flying to New York, US. There might be a delay in answering some questions, but, I hope to be back quite soon.

I will be taking lots of dollars to take advantage of the discrepency in the dollar / sterling exchange rate.

Economists, often say there should be no ‘free money on the table’. But, buying a new Mac laptop in the US, could save me £500 due to the weakness of the dollar. I guess someone has to do well out of the declining dollar…

What Caused Globalization?

Readers Question: Evaluate the significance of the factors which have contributed to globalisation. You may use diagrams if you wish.

Globalization is not a new phenomena. The world economy has become increasingly interdependent for a long time. I have previously written various factors that have helped explained the rise in globalization here 

In evaluation I would make the following points.

  • It is hard to precisely define globalisation there are different interpretations about what we actually mean, therefore, there are differing factors that explain it. Continue reading →

Questions on Exchange Rates UK

1)  You say depreciation causes inflation for the three reasons you mention, but later, that in the long run, a higher rate of inflation will cause depreciation.  So my first question is how are these two phenomena linked?  Is ‘long run’ the key; i.e. it takes a prolonged high inflation to cause a devaluation,  but devaluation causes inflation sooner? How long does it take for those three reasons to really kick in?

It depends, there is no straight answer. The two phenomena may occur simultaneously. Also it is complicated by the fact that many factors affect the exchange rate apart from just inflation. (e.g. short term interest rates)

2)  My next question is that I’m aware that factors such as rising commodity prices can exert upward inflationary pressure,  but are there any other factors that affect the devaluation of a currency - or is it purely down to inflation?

Many factors can affect exchange rates. These include:

  • Interest Rates - lower interest rates cause less hot money flows and depreceation.
  • Expectations - If investors expect a currency to devalue they will sell less. Confidence and market expectations are important in determining exchange rate
  • Current account deficit. A large current account deficit may put downward pressure on exchange rates Continue reading →

Devaluation, Competitiveness and Inflation

READERS QUESTION Inflation makes exports less competitive because prices rise, but also, currency devaluation makes exports more competitive. Since devaluation of the currency and inflation are kind of conincidental (because as the currency becomes cheaper, it increases demand and also price), what exactly happens to the competitiveness of exports?

If a currency depreciates (falls in value). Then it tends to cause inflation for three reasons:

  1. Exports are cheaper. Therefore Net Exports tends to rise causing higher AD and demand pull inflation
  2. Imports are more expensive. (The £ Sterling price of imports is higher, because the currency is weaker) Therefore we get imported inflation
  3. Because UK exports become more competitive it is argued people have less incentive to cut costs

Effect of Inflation on Competitiveness

You are right if UK inflation is higher than other countries then UK goods will become comparatively less competitive. This will cause lower demand for UK exports (depending on elasticity of demand) Continue reading →

Devaluation and Depreciation Definition

I read in a text book that under a floating exchange rate a “devaluation” is not possible as a means of improving international competitiveness but a “depreciation” is. Could you please explain to me what a depreciation is as opposed to a devaluation.

Interesting question.

In general terminology devaluation and depreciation are often used interchangeably. In fact for A Level economics it is not essential to distinguish between the two (but, of course it is nice)

Definition of Devaluation:

A devaluation is when a country makes a conscious decision to lower its exchange rate in a fixed or semi fixed exchange rate. Therefore, techically a devaluation is only possible if a country is a member of some fixed exchange rate policy.

  • For example in the late 1980s, the UK joined the Exchange Rate Mechanism ERM. Initially the value of the Pound was set between say 3DM and 3.2DM. However, if the government thought that was too high, they could make the decision to devalue and change the target exchange rate to 2.7DM and 2.9DM.
