Problem 7: Most individuals of goodwill subscribe to some form of the notion that there should be "equal pay for equal work." However, most pay scales for government workers (e.g., those for public school teachers) reward additional years of experience without regard to the quality of a teacher's work. (a) Is this economically efficient? Argue for or against. (b) What if this way of paying teachers results in the average woman teacher earning more than the average male teacher (or vice-versa)? Should this be legal? Why or why not?
