However the third phase of increasing productivity in the mining sector was accompanied by increasing supply of mining output and energy resources from other countries, which led to the collapse of the commodity prices that led the Australian exports value to fall as a result of which the GDP growth rate dropped down for the last two to three years as shown in the graph below.
The short run and long run impacts of increasing GDP over the last decade from 2005 to the year 2012 has resulted in decreasing the unemployment of the country. However over the last two to three years, there has been an increase in unemployment due to stagnation in the mining sector and falling price levels (Yeomans, 2016).
Question 2: Determinants of growth and fiscal budget of 2016-17
There are various demand and supply side factors that affect the growth and development of an economy. An expansionary budget such as the current budget of 2016-17 would improve investments in various sectors and generate employment which would increase the GDP growth rate of the economy. The standard determinants of growth in an economy include supply factors such as improvements in natural resources and enhancing skills and employment opportunities for the human resources.
Growth of an economy can also be induced by making investments in the capital goods industry which will increase the production of goods and services in the economy. Innovation and technology can also increase efficiency allowing for increasing productivity and economic growth. Similarly the demand side factors affecting economic growth includes increased aggregate demand in the economy and also increasing efficiency which includes increases in productive efficiency by producing in the least cost way and also allocative efficiency by putting the resources in the optimum uses for optimum purposes.
Discussing the current budget on the face of standard determinants of growth will tell us that the Australian government is on the expansionary phase to turn the mining sector based development to a broad based development that is focused on other manufacturing industries and the service sector. The growth of employment opportunities have been in the business services sector and goods related and household services sector rather than in the mining and construction sector. More than 3 lakh jobs were created in these three sectors which has diversified the sources of growth and development for Australia which was concentrated in the mining sector development during the boom (Budget, 2016). This has led to improvements in non-mining sectors of the economy and this was boosted by the lower exchange rate that improves the exports opportunities in the light of new free trade agreements signed by Australia with south Asian countries. The Government has lowered the tax rate for full time wage earners and small business for encouraging them to expand themselves. The new trade agreements signed by Australia with China, Japan, etc, have increased the competitiveness of Australian exports and this was augmented by the expansion of investments in export oriented industries. Investments in the infrastructure sector have also improved transportation of people and goods across Australia. Lowering the tax rates for the wage earners from increasing the tax rate from $80000 to $87000 as the income above which the tax rates are applicable would encourage workers to work more and thus workforce participation rate would increase.
Question 3: Inflation and Unemployment in Australia
The data on inflation (CPI-percentage change) and Unemployment is collected from the ABS website and tabulated in the table below.
We can see a negative or inverse relationship between unemployment and inflation as given by the short run Philips curve. This is shown by the trend line where it shows the negative relationship between the two. Philips curve concept as given by A.W. Philips says that when inflation increase in the economy, this means that more goods and services are being produced and sold which means that there is increase in the employment of resources (including human resources) and this reduces unemployment in the economy. During the recent years in Australia, we can see that inflation is at its lower boundary nearing 0.2 and unemployment is at its higher boundary (above 6.2 or so) as can be seen from the table.
Question 4: Effect of these changes in real output and price level (using AS-AD model)
The assumptions we are taking in this model are
When the price of iron ore, which is the major exports of Australia decreases, the net exports (which is the exports- imports) decreases. As net exports is one of the component of aggregate demand, a fall in net exports will result in aggregate demand shifting to the left to AD2 as shown in the figure above and this decreases the output and price level. As there is an increase in unemployment, the price level also goes down (Layton & Robinson, 2012).
(b)a drought leads to a substantial fall in Australian agricultural output,
In this case, as the supply of agricultural output is decreased due to a drought, this results in short run aggregate supply curve shifting to the left from SAS1 to SAS 2. This leads to increase in the price level and further unemployment as shown in the diagram above. (McEachern, 2012)
(c)the government spends significant money in developing a broadband internet network across the country,
As government invests money in expanding broadband network across Australia, it shifts the aggregate demand to the right to AD2 as shown in the figure above. As government expenditure is part of the aggregate demand curve, any increase in govt expenditure will shift the AD curve to the right. This increases the real output in the economy and also increases the price level as employment as increased. (Layton & Robinson, 2012)
(d)the price of oil, a product Australia primarily imports, fall substantially.
When the prices of oil (world prices) which is one of the major imports for Australia decreases, there is an increase in the net exports (as the imports value as decreased). Net exports = exports value- imports value. (Mankiw, 2009) This will increase the net exports and there by the aggregate demand will shift to the right increasing the real output of the economy and also the employment of resources and hence the price level would also go up.
