Final answer:
An increase in computer technicians' wages will attract more high-skill workers over time, according to the demand and supply model.
Step-by-step explanation:
The sentence appears to be referring to the effects of increased wages for computer technicians on the labor market. When wages increase, it can attract more individuals to pursue careers as technicians due to the higher pay. This is a principle derived from the demand and supply model, which stipulates that higher wages can lead to a rightward shift in the labor supply curve, thereby attracting more high-skill workers to the industry in the long run. As a result, the sentence could be completed as: "An increase in the wages of computer technicians which will attract additional technicians in the long run". Historical data from the National Center for Education Statistics supports this, showing that wages have risen substantially for those with college degrees, which include many high-skill workers, in comparison to their counterparts with only high school diplomas.
