Assume that an employer believes that the “efficiency” (e) it can get from a particular worker, as a function of the hourly wage (w), is given by function e = –0.125w + 0.15w2 – 0.005w3, at least up to a wage of 30. a. Create a table of w, e, e/w, and w/e for wages equal to 5 and 10. b. Which wage gives the highest ratio of efficiency per unit of labor cost?
