Unemployment and Labor Economics

Frictional unemployment is an unemployment situation where people are not unemployed owing to not getting any job but they are unemployed because they are searching for a new job or they are getting transferred from one employment to the other. Frictional unemployment remains consistent with full employment if it is at a rate of 3-4% of the full employment. 

When the aggregate spending is not sufficient to produce an adequate level of output which requires full employment of available resources then it means aggregate demand is less than aggregate supply, then the planned inventory rises above the desired level. To clear the unwanted increase in inventory, firms plan to reduce the output which reduces the employment in the economy and results in AD=AS. This equilibrium point is below the full employment level of equilibrium which is called underemployment equilibrium. 

Underemployment occurs when a person's skills, education, or experience exceed the requirements of their current job. A postgraduate working as a peon is a classic example of credential mismatch. The term 'under employment' (two words) is used here to describe this phenomenon. Unemployment means no work at all, while structural and seasonal refer to specific causes of joblessness, not credential mismatch.

When due to introduction of new machinery (change in technology) some workers tend to be replaced by machines; their unemployment is termed as Technological unemployment.

In the short run, the aggregate supply curve is typically modeled as a function of the level of employment, assuming other factors like capital and technology remain constant. As employment increases, output increases along the short-run aggregate supply curve.

In Keynesian theory, aggregate demand is the primary driver of output and employment in the short run. Changes in aggregate demand lead to changes in the equilibrium level of income and employment.

A person who is not gainfully employed, that is, a person who is not paid in monetary terms or in kind in return of his work, is known as an unemployed person since he cannot contribute in the GDP of a country.

Unemployment benefits provide financial assistance to workers who have lost their jobs through no fault of their own, helping them maintain a standard of living while seeking new employment.

Outsourcing is the business practice of hiring parties outside of a company to perform services or create goods that were traditionally performed in-house, often in countries with lower labor costs.

Disguised unemployment occurs when more people are employed than are needed for a task, resulting in zero marginal productivity. This is most prevalent in the agricultural sector, where family members often work on the same plot of land regardless of the actual labor requirement.

Cyclical unemployment is directly linked to the ups and downs of the business cycle. When the economy is in a recession or downturn, aggregate demand falls, leading to layoffs.

Voluntary unemployment refers to a situation where individuals choose not to work at the prevailing wage rate, often because they are looking for better opportunities or are satisfied with their current situation.

In rural India, the economy relies heavily on agriculture, which is inherently seasonal. Additionally, the surplus of labor on small landholdings leads to widespread disguised unemployment.

Urban unemployment is primarily driven by the lack of jobs matching the skills of the educated population and the industrial structure of cities.
