Oligopoly differs from perfect competition and monopolistic competition in that
A) barriers to entry are lower in oligopoly industries than they are in perfectly
competitive and monopolistically competitive industries.
B) demand and marginal revenue curves are more useful for analyzing oligopoly than
they are for analyzing perfect competition and monopolistic competition.
C) because oligopoly firms often react when other firms in their industry change their
prices, it is difficult to know what the oligopolist’s demand curve looks like.
D) the concentration ratios of oligopoly industries are lower than they are for perfectly
competitive and monopolistically competitive firms.
Suppose in Finland a worker can produce either 32 cell phones or 4 kayaks while in
Canada a worker can produce either 40 cell phones or 10 kayaks.
a. Which country has an absolute advantage in cell phone production? In kayak
production?
b. What is the opportunity cost of 1 cell phone in Finland? In Canada?
c. What is the opportunity cost of 1 kayak in Finland? In Canada?
d. Which country has a comparative advantage in cell phone production? In kayak
production?
e. Suppose each country has 1,000 workers. Currently, each country devotes 40 percent
of its labor force to cell phone production and 60 percent to kayak production. What is
the output of cell phones and kayaks for each country and what is the total output of cell
phones and kayaks between the two countries?
f. Suppose each country specializes in the production of the good in which it has a
comparative advantage. What is the total output of cell phones and kayaks in the two
countries?
