Assume now that the market in Question 2 is served by a profit maximizing monopoly. The firm is sufficiently large that its marginal cost is equal to the market supply curve in Scenario 3a. Therefore, market demand is still P = 150 - .05Q and the monopoly firm’s MC = 0.45Q + 10. The monopoly has marginal revenue MR = 150 - Q. The monopoly is a large well run firm with a short run average total cost of ATC...

QUESTION 1: The Masters is one of the four major golf tournaments. Only the 60 golfers with the lowest two-round total advance to the final two rounds (unless several people are tied for 60th place, in which case all those tied for 60th place advance). Suppose that for a certain year the least-squares line for predicting second-round scores from first-round scores has equation yˆ=51.43+0.315xy^=51.43+0.315x (a) Find the predicted (±±0.001) second-round scores for a player who shot 80 in the first...

5. The number of publicly listed firms has decreased by about half over the last 20 years even though the market capitalization of these firms is up more than 20x. Additionally, the 30 largest firms now account for about half of all public company earnings; in other words, firms are getting much bigger. Why has the number of public companies decreased so much? Are firms just getting bigger or are more companies staying private? Why might a firm wish to...

Over the last 20 years, the number of students who hold a job while attending university fulltime has increased. Work responsibilities may ‘compete’ for time and energy with course responsibilities, and consequently, may affect student academic success. An educational researcher is interested in determining whether student employment influences academic success. The research has obtained a relevant sample of university students, and has determined the following information for each student: their employment status (specifically, the typical number of hours worked per...
