The paper "Comparative Advantage in a Changing Global Economy" is a great example of an assignment on macro and microeconomics. All the five countries experienced steady growth in GDP per capita between the years 2001 and 2008. However, Australia, Russia, and the United Kingdom experienced a decrease in GDP per capita between the years 2008 and 2009. China and Indonesia recorded a steady improvement in GDP per capita in the same period. Between the years 2009 to 2012, Australia, Russia, and the United Kingdom registered a positive change in GDP per capita thus joining the other two economies i. e.

China and Indonesia. During the period of 2008, there was a global economic meltdown that affected most sectors of the economy in developed countries such as Australia, the United Kingdom, and Russia among others. According to the World Bank (2012) report, these economies did not perform well during this unfortunate period. Companies collapsed while other economic activities paralyzed. The significant drop in GDP per capita in the UK, Australia, and Russia is a clear indication of how the global economic meltdown affected the world economies. Question Three: GDP Explanation: All economies in this particular case registered positive improvement between 2001 and 2006.

Russian GDP declined in the year 2006/2007. Between the years 2007 and 2009, Australia, Russia, and the United Kingdom were all affected negatively by the global economic crisis. Decrease in GDP in these three economies is a clear reflection of impact of the global meltdown on the world economy. China and Indonesia have safeguards against the crisis hence continued to report a positive change of GDP each year until 2012. Of all these economies, Australia was the worst hit by the crisis hence a huge negative difference in GDP between the years 2007 AND 2008.

After this period, the economy has taken a desirable recovery path. GDP GROWTH RATE Just like an earlier explanation on GDP, growth rate takes the same route. The annual growth rate represents the difference between GDP registered in different periods. An increase in GDP signifies the growth of the economy as a whole. In the case of these five countries, two of them, i.e. Australia and the United Kingdom reported a negative growth rate between the years 2007 and 2008.

The World Bank report (2012) indicates the sign of economic recovery in these countries from 2009 to 2012. The GDP growth rate started reporting a positive difference. China and Indonesia maintained positive growth throughout the period even when the global crisis hit all developed economies. Australia in particular experienced a slow growth rate from 2005 to 2010 which may be a result of diminishing returns among other factors (Dyster, Barrie, and David, 67). Consequently, economists cautioned the government on the need for quick reforms in major industries and further investment in infrastructure.

Before this period, this country experienced steady growth than other high-income economies. INFLATION Inflation generally indicates overall price levels of commodities and services in an economy. When the inflation is high, the cost of products rises hence reducing the purchasing power of the currency in that particular economy (Dixit, Avinash, 46). Each country, in this case, has tried to ensure the inflation remains at the desired level. China for instance has maintained low price levels of commodities until 2007 and 2008 when its inflation was higher than usual (Eichengreen, et al 73).

It had the same experience in 2010 and 2011. In Australia, the rate of inflation has been high except in 2009 and 2012. The United Kingdom has maintained low level of inflation throughout except 2008, 2010, and 2011. When the inflation is low, the country supplies most of its products thus increasing GDP. Inflation affects currency exchange in an economy hence when it is low; the current demand is usually high hence making the GDP to be high. In such a situation, the economy is said to be improving. UNEMPLOYMENT The strength of any economy is mainly determined by the level of unemployment.

A high level of unemployment indicates that there is low purchasing power within the economy hence low GDP. When people within the economy are unemployed, there is low consumption of products and services. Consequently, GDP in that particular economy is always low. Between the years 2008 and 2009, Australia, Russia, and the United Kingdom had a high rate of unemployment. It was due to the collapse of many institutions and the stagnation of various sectors of the economy.

Most organizations lay off their employees as a measure of coping with economic crisis. Australia, Russia, and the United Kingdom are good examples of economies that had high unemployment during this season. China and Indonesia were not affected since their economies do not rely much on the formal sector. In China particularly, the economy relies on the informal sector which usually account for more than 50% of its products (Fidrmuc, Jarko, and Iikka, 299). The country also has a stable and sustainable market base which is developing economies. Question Four: MPC which is the marginal propensity to consumer refers to an aggregate increase in income that a consumer decides to spend on products and services instead of saving.

It represents a change in the level of consumption as a result of the change in earnings or income. When MPC is 0.7, it means that consumption increases by 70 cents whenever the income increases by an extra dollar. GDP T YD C I G NX AE UI Y will: 18000 4000 14000 7600 4500 5000 4500 21600   Increase 22000                   26000                   30000                   34000                   38000 10,000   15,400 11,000 12,000 11,000 49,400   Increase 42000                   YD is the disposable income that is calculated by first determining the Gross income then subtracting all deductions including direct taxes and adding any available benefit. C stands for consumer spending or total consumption in an economy. AE is the collective spending or aggregate expenditure in an economy.

It is determined by adding total consumption (C) + Government expenses (G) + Net Export (NX) + Aggregate Investment (I). UI stands for unemployment Insurance which is the amount given as compensation to the people who have lost their income in the economy. The equilibrium level of income is realized when the aggregate demand for products and services is at par with the supply level in a given economy.

In a nutshell, GDP expresses equilibrium income. It is expressed as GDP = C+I+GP+NX Question Five: The potential level of GDP refers to the optimum output level an economy can produce provided the rate of inflation remains constant. THE potential GDP level at $ 38,000 implies that there are a sustainable employment level and stable consumption in this economy. Such an economy may be characterized by the application of perfect measures and the implementation of essential ideas from experts (McConnell, Campbell, et al 179).

In this case, the government exports more products and applies restriction measures to imports. In addition, it tries to ensure the employment level is high in order to sustain the consumption of products and services. When the GDP level is at $ 18,000, Government expenditure and Total Investment stand at $5,000 and $4,500 respectively. This implies that the $ 9,500 is spent as a stimulus package. When the GDP is at $ 38, 000, then the government spending and investment ought to be higher than in the earlier case. In the latter case, the government will need a stimulus package of $ 23,000 to sustain this level of GDP. The stimulus package, in this case, is less than the change in income level since the government creates more employment opportunities while retaining the previous level.

An increase in stimulus and investment implies open opportunities for employment within the economy hence increasing level of income.
