Increasing industry concentration a concern

Economists have long understood that competition between firms brings the advantages of lower prices, improved quality and greater consumer choice. This is because firms deliver on these or they will be competed out of the market. 

The Australian Competition and Consumer Commission (ACCC) chairman has warned that market concentration (the percentage of market share held by the biggest firms) has risen to a level where consumers are possibly going to be worse off.

If a firm has monopoly power then they typically charge more and sell less, but earn higher profits. Over the last few decades mergers and takeovers have led to a very high proportion of Australian output being concentrated in the top 100 firms.

This provides a problem for the ACCC who regulate competition. The article below suggests that a change of rules whereby the firms that merge or want to takeover another have to prove the result will not harm competition. At present the ACCC have to prove it would harm competition.

An interesting point made by the ACCC is that if we want the benefits of economies of scale to work through to lower prices then we have to maintain a competitive environment. In other words a merger/takeover may improve productive efficiency but harm allocative efficiency.

The ABC cover the story here

This article deals directly with competition policy in Australia so is directly relevant to VCE economics. This is a part of IB economics also, and the harm that monopolies do to efficiency is often visited on Paper 1 of Higher Level in questions on the theory of the firm.

Headline inflation rise hides continued sluggishness

The Australian CPI figure released yesterday showed a significant jump in inflation, and for some this was great news s at least inflation headed back towards the target range of the Reserve Bank of Australia (RBA). This is almost certainly a false hope.

Looking at the figures it is clear that the massive rise in fruit and vegetable prices, largely due to massive flooding affecting supply, has made the CPI figure look more healthy than it really is. Take that out and the underlying rate of inflation actually fell.

Australia's headline and underlying inflation compared

The low inflation figures show that economic growth the Australian economy continues to slow down, and this is not good news. The end of the mining boom is severely affecting WA and the Northern Territory, but indicators don't show massive growth in the rest of Australia that will compensate.

Once again Greg Jericho in The Guardian provides excellent analysis and data of the inflation figures and considers the likely impact on monetary policy settings.


VCE students are especially urged to understand the pressures in the economy at present - demand side pressures on policy settings. The article makes use of the Australian underlying inflation measures which are required knowledge.
IB students can use this as an example of inflation and monetary policy. The article is particularly strong at looking at how the various factors link together to give an overview of the health of the economy and the process and implementation of monetary policy.

Exploring Australia's unemployment rate a little more

Australia's unemployment rate is falling. That should be good news. However as pointed out a couple of posts ago this is not as straightforward as it seems.

The labour market is complex and what appears to be a substantial fall in unemployment masks a rise in part-time work, a fall in the participation rate and sharply different experiences of workers based on age and gender.

This article analyses the figures, using plenty of data in charts. The conclusion is that headline figures can appear good, but mask a serious problem.

As I made many relevant points before on Queensland I won't write much here. It is critical that you read the article to the end however.


This is an article that provides vital information for VCE candidates on what is happening to unemployment in Australia.
IB candidates are also able to use this as an example and look at the key issues of measuring unemployment and should also consider how such unemployment can be cured. Note this article is not suitable for an IA as it is an analytical article - it does the job the IA should do, but there should be other articles out there on the latest unemployment figures (hint hint).

What is the best way to achieve equity?

Equity is a measure of fairness, and therefore a matter of opinion. The difference of opinion extends beyond what the best distribution of income is to how we should achieve it.

Some people believe that the way to achieve equity is through evening up in-work income. That can be done by raising minimum wages and taxing incomes progressively. Others believe that the best path is to pay benefits to those who require additional income. Both approaches will help reduce income inequality.

In Australia there is presently a debate between government and Trade Unions on the setting of the minimum wage. Australia has for many years had a very high minimum wage, but it has been falling in terms of the proportion of average wages this represents.

The Trade Unions want the minimum wage raised so that it is maintained at 60% of average incomes. The government does not want to commit to that because it fears that this may raise unemployment. (That would be cause real wage unemployment where the minimum wage in some industries is set above the market equilibrium.)

This is actually an argument of equity vs efficiency. There is no doubt that a high minimum wage promotes equity, the difference in take home pay will be made smaller. However it may harm efficiency.

Markets work through incentives. Earning  higher profit incentivises  firms to lower costs and improve quality in order to sell more products. It is a similar issue with workers, they are incentivised to work through wages. Higher wage rates attract more hours of work from workers.

If the minimum wage is too high there are two possible detrimental effects.
1. Firms cannot pay different rates of pay to different workers below the minimum wage
 A worker who is more productive should earn more than one who is less productive. However if both workers value to the firm is less than the minimum wage then both receive the same wage or, possibly, neither is employed.

2. The incentive to work harder and achieve improved skills and position is removed when there is equality in payment. The rational choice is to do the easier job yet get paid the same. Any move towards greater equity in income risks enhancing this effect and the economy suffers.

Overall this means that the economy is denied the competition it needs to achieve productive and allocative efficiency and as a result resources are misallocated.

There is no right answer to the question of the 'best' distribution of income. The trade-off between equity and equality is a real one though and must be considered in any policy proposal.


This matter is of value to VCE students as the minimum wage is a key part of policy for the goal of equity. For IB students this has wider implications including the causes of unemployment and supply side policy.

Unemployment - the headline figures can disguise the truth

In Australia the rate of unemployment has generally been falling. This is usually good news, but there are other subtle points to consider, such as the situation in Queensland where the fall in unemployment might be hiding a more serious problem.

The unemployment rate is measured from a base figure of those people of working age who are looking for work or in work. This group are participating in the labour market, those who choose not to or cannot work are disregarded. The proportion of working age people active in the labour market is therefore called the participation rate.

The fact some people decide not to look for work can affect the unemployment figures and the article below gives an example of this. Unemployment in Queensland is falling, but some claim that this is because some people are so fed up with not finding a job they are simply giving up. If you are not seeking work you are no longer counted as unemployed and the unemployment rate appears to fall.

The discouraged workers as they are known are still without work. The participation rate has fallen and, in the case of Queensland, the number employed falls, but the unemployment rate also falls.

This could indicate a very serious problem with a number of people simply becoming detached from the labourforce, suffering all the personal costs of unemployment, but receiving none of the help the unemployed should receive. In addition the economy is loosing out on all the output those people could produce if they were in work.

Australia's participation rate, since 2011 there has been a downward trend


This story applies equally to IB and VCE students. The problems of unemployment and the difficulty measuring it is a core concept. There are also links to economic growth and supply-side economics as those not working represent a loss of output and those not seeking to work a serious restraint on aggregate supply.

Losing and gaining from inflation

Continuing the UK pound theme today I will look at a story on the effects of higher inflation in the UK.

Inflation has been subdued across the world in recent years despite very expansionary monetary policies being pursued by all central banks. In the UK inflation is well below the Bank of England target of 2% and in August was just 0.6% on the CPI measure. It has rocketed to 1% in September.

So far there is only anecdotal evidence that the fall in the value of the pound is responsible, but import prices will rise with the near 20% fall in the value of the pound since June. This would cause cost-push inflation and will compliment the demand-pull inflation that the Bank of England are encouraging by their recent reduction in interest rates to 0.25%.

The article, again from the BBC, looks at the effects higher inflation might have on households. It points out that when inflation reaches a rate higher than wages growth then real incomes start to fall, making people worse off. It also notes that those on benefits, many of which are frozen in value until 2020, also lose out.

One group that is protected are those who receive the old age pension (that is everybody in the UK who are old enough, it is not means tested). The old age pension goes up by at least 2.5% a year, or inflation on CPI or wages growth - whichever is higher. This protects the old against an important cost of inflation.

Note the link in the article to 'winners' from inflation.


The costs and benefits of inflation is relevant to everyone. This provides a very useful survey of the issue facing people today with low inflation and the impact of rising inflation.

Exchange rates as a shock absorber

Economies are subject to 'shocks'. Classic ones include the jump in the price of oil in the 1970's, the rise in commodity prices in the 2000's and the Gulf wars. When they occur there is an unexpected 'shock' to Aggregate Supply or Aggregate Demand (AD). This can result in inflation, unemployment or both in the domestic economy.

The diagram below shows the effect of a shock to AD, say the shock of Brexit to the UK economy reducing consumer and business confidence. This would reduce Consumption and Investment expenditure, shifting AD to the left.

One of the benefits that an economy with a floating exchange rate has in this situation is that the currency can depreciate and act as a 'shock absorber'. The shock of Brexit has led many to believe that the UK economy will perform less well in the future and this, they reason, will mean the UK currency, the pound, will be worth less as a result.

This has led to a lower demand to buy pounds and increased selling as people seek to hold their wealth in other currencies that are less likely to loose value. The falling pound (see two posts ago for that) has an important benefit for the UK economy. 

The lower value of the pound means that UK exports now cost less in foreign currency and import prices in the UK will rise. As a  result there will be a rise in the volume of exports and fall in the volume of imports (the law of demand). As long as the Marshall-Lerner conditions hold (and they will) this will mean a rise in the value of Net Exports (X - M) which is a component of Aggregate Demand. This will, at least partially, offset the fall in AD - absorbing part of the shock.

Many argue that this is exactly why the UK was wise not to join the Euro.


This is very much an IB post, and touches on macroeconomics and international trade. It is particularly useful as an example of the argument around single currency areas where asymmetric shocks are likely.
