Macroeconomics/Types and Causes of Unemployment
Although most people usually refers to a certain level of unemployment in an economy, it is important to understand the different types of unemployment and their implication to the economy.
Cyclical unemployment is caused by a downturn in the business cycle. When aggregate demand falls in the economy, the demand for labor resources(a derived demand) also decreases as people are less inclined to purchase goods and services. Firms would be forced to layoff workers in order to maintain an acceptable profit margin.
On the other hand, should aggregate demand rises in an economy, the demand for labor resources would increase, accommodating for the increased demand for goods and services.
Structural unemployment occurs because of skill mismatch between those demanded by employers and those processed by employees. Economies in transition such as when Australia transition from the mining boom to a service based economy, would usually increase the level of structural unemployment. Workers skilled at industries that are declining would find their particular skill sets are no longer appropriate in newer industries where the type of skills required may be different. So even if the unemployed person wants to work, and the firms in the new industry require more labour, the mismatch of skills means that the structurally unemployed cannot find work.
