Answer:
A. All of these 3 other possible answers that are listed here are true reasons.
Step-by-step explanation:
If we are to use wage the rate of change in wages or inflation, as a proxy for inflation in the economy, when there is unemployment, the number of persons searching for work is significantly greater than the number of jobs available for the people who are unemployed. What we mean is, the supply of labor is greater than the demand for it.
With the availability of many workers, there's little need for employers to "bid" for the services of employees by paying them good wages.
