Use a game tree to illustrate why an aircraft manufacturer may
price below the current marginal cost in the short run if it has a
steep learning curve. (Hint: Show that learning by doing
lowers its cost in the second period.)
Assume for simplicity the game tree is illustrated in the figure
to the right. Pricing below marginal cost reduces profits but
gives the incumbent a cost advantage over potential rivals.
What is the subgame perfect Nash equilibrium?
A. The game does not have a Nash equilibrium.
B. The Nash equilibrium is for the incumbent to price
below marginal cost and for the rival to enter
regardless of whether the incumbent prices above
marginal cost.
○ C. The Nash equilibrium is for the incumbent to price
below marginal cost and for the rival to not enter
regardless of whether the incumbent prices above
marginal cost.
D. The Nash equilibrium is for the incumbent to price
below marginal cost and for the rival to only enter if
the incumbent prices above marginal cost.
E. The Nash equilibrium is for the incumbent to price
above marginal cost and for the rival to only enter if
the incumbent prices above marginal cost.
