Answer: Somewhat less than 50%
Step-by-step explanation:
Here is the complete question;
Suppose that a labor economist performs a statistical analysis on economywide worker wages using standard, measurable explanatory factors, such as job characteristics, years of schooling, and so forth. How much of the variation in worker wages can be accounted for by such measurable explanatory factors?
a. Somewhat less than 50%.
b. Somewhat more than 60%
c. Nearly 100%
d. About 0%?
The variables which are typically removed from the quantitative analysis of wages are those which cannot be directly measured, directly observed or normative in nature.
Chance plays a vital role in deciding ones wage, the type of job one applies for and gets, and the salary that can be gotten. Chance cannot neither be measured nor observed. Natural ability cannot also be quantified, observed or measured. These variables are also subject to normative judgement.
Based on this analysis, the measurable traits will account for less than 50% of total variation in the wages.
