All of the following factors affect the level of wages except which of the following?

a.) the actions of labor unions

b.) the size of the labor pool

c.) the level of immigration

d.) the gross domestic product

The gross domestic product does not affect the issue.

Explanation:

GDP is basically a fiscal measure of the value of all goods at market that are produced by the end of a specific time period, usually, over a year. The GDP might be a reflection of the income but does not affect the wages of the labourers as wages are just a basic mean of provision to lead a sufficiently comfortable life.

The wages can be affected by the size of  labour pool and also immigration. When the labour pool expands, there are more labourers to be paid and hence this might affect the amount each one receives.
