Question

How do skill ,type of job and demand for products affect wages?

Answer 1

Answer

The skill set of a person may be valuable or non-valuable based on what the demand for a certain product is. The more value for a skill the higher of a wage because the employer would want to keep the person with the skill. Like if having a cell phone is in high demand, people who have a skill in engineering will be paid more because they need someone who can program the phone to be the best.  

Answer 2

The higher job and higher skill of making or selling said product means people are more likely to buy so you will have higher wages
