BUSINESS AND INDUSTRIAL ECONOMICS [G-O] Final exam June 21st 2023 NAME AND SURNAME ________________________________________________________________ STUDENT ID________________________________________________________________ Multiple choice questions 1) Consider a Bain, Sylos Labini and Modigliani model with absolute cost advantages.

BONUS d) All the other options are correct. 2) Firms A and B are competing according to a Stackelberg oligopoly. The inverse demand function is P = 250 – 2Q. The total cost function for both firms is TC = 5 + 2q. What is the quantity produced by the follower? a) 31. BONUS b) 62. c) 124. d) None of the other answers is correct. 3) Please gauge the validity of the following statements: a) In principle, the double marginalization problem should require the intervention of ex-ante regulation in order to be solved. b) In principle, the double marginalization problem should not require any regulatory intervention in order to be solved.

There are no fixed costs. Determine the difference in social welfare between these two…
