The correct answer is D. Mobility of labour increases efficiency of labour and increases division of labour.
Mobility of labour refers to the ability of workers to move between different jobs, occupations, and industries. It is often measured by the number of people who change jobs in a given period of time.
There are several reasons why mobility of labour is important. First, it allows workers to find jobs that match their skills and interests. This can lead to higher levels of job satisfaction and productivity. Second, mobility of labour helps to ensure that the labour force is evenly distributed across different industries and occupations. This can help to prevent shortages and surpluses of workers in particular areas. Third, mobility of labour can help to promote economic growth by encouraging workers to move to areas where there are more job opportunities.
There are a number of factors that can affect the mobility of labour. These include the availability of jobs, the cost of moving, and the level of education and training. In some cases, government policies can also play a role in promoting or discouraging mobility of labour.
Overall, mobility of labour is an important factor in the functioning of the labour market. It can lead to higher levels of job satisfaction, productivity, and economic growth.
Here is a brief explanation of each option:
- Option A: Increases efficiency of labour. This is because mobility of labour allows workers to find jobs that match their skills and interests. This can lead to higher levels of job satisfaction and productivity.
- Option B: Spoils labour. This is not true. Mobility of labour can actually help to improve the skills and productivity of workers.
- Option C: Increases division of labour. This is because mobility of labour allows workers to specialize in particular tasks. This can lead to higher levels of productivity.
