Macroeconomics: Potential Output, Business Cycle, and More
Explain the concept of potential output and why actual output can differ from potential output?
(2 marks)

Potential output is the amount of output that an economy can produce when using its resources such as capital and labour, at normal rates.

Potential output is not a fixed number but grows over time, reflecting increases in both the amounts of available capital and labour and their productivity.

As capital and labour can be utilised at greater than normal rates, at least for a time, a country's actual output can exceed its potential output.

Identify two factors that might cause a change in the level of potential output. For each factor briefly explain why they can affect potential output.
(2 marks)

Unfavourable weather conditions, such as severe drought, could reduce potential output growth in an economy such as Australia's, or a decline in technological innovation might also reduce potential output. This would affect potential output as it reduces the availability of resources such as capital and labour. Under the assumption that the country is using its resources at normal rates, so that actual output equals potential output, a significant fall in potential output growth would tend to result in recession.

Similarly, new technologies, increased capital investment, or a surge in immigration that swells the labour force could produce unusually brisk growth in potential output, and hence an economic expansion or even a boom. This is so as availability of resources has increased.

- Growth in potential output itself may slow down or speed up, reflecting changes in the growth rates of available capital and labour and in the pace of technological progress.

Identify and briefly explain the main features of the business cycle.
(2 marks)

business cycles are usually thought of as being characterised by periods of transition from peak to trough (a contraction) and then from trough to peak (an expansion)

    Basic Concepts 1. The relationship between the quantity of output (such as wheat, steel, or automobiles) and the quantities of inputs (of labor, land, and capital) is called the production function. Total product is the total output produced. Average product equals total output divided by the total quantity of inputs. We can calculate the marginal product of a factor as the extra output added for each additional unit of input while holding all other inputs constant. 2. According to the law of diminishing returns, the marginal product of each input will generally decline as the amount of that input increases, when all other inputs are held constant. 3. The returns to scale reflect the impact on output of a balanced increase in all inputs. A technology in which doubling all inputs leads to an exact doubling of outputs displays constant returns to scale. When doubling inputs leads to less than double (more than double) the quantity of output, the situation is one of decreasing (increasing) returns to scale. 4. Because decisions take time to implement, and because capital and other factors are often very long lived, the reaction of production may change over different time periods. The short run is a period in which variable factors, such as labor or material inputs, can be easily changed but fixed factors cannot. In the long run, the capital stock (a firm's machinery and factories) can depreciate and be replaced. In the long run, all inputs, fixed and variable, can be adjusted. 5. Technological change refers to a change in the underlying techniques of production, as occurs when a new product or process of production is invented or an old product or process is improved. In such situations, the same output is produced with fewer inputs or more output is produced with the same inputs. Technological change shifts the production function…

    Technical progress causes the production process to change over time. For example, wider roads and improved traffic control systems may result in increased output (i.e., bus miles) even though the number of buses (i.e., capital input) and drivers (i.e., labor input) remains constant. Likewise, the replacement of older buses with new models may increase output since the new buses may be faster and more maneuverable. Finally, as the experience level of the bus drivers increases over time, output may increase even though the number of drivers remains constant…

    When JLR have finished booming and doing well they would end up going down and earning a bit less money. This could be because people are not interested in the businesses cars at this present time in the year or because JLR have spent a lot of money recently and do not have anything to show for it. A downturn is a good example of things getting worse before they get better again. This is identified by a fall in GDP in one quarter.…
