Answer:
E. None of the above
Step-by-step explanation:
The standard reaction function of firm 2 is given as = a-Cb/2b - 1/2*Qa
P = 30 - (Qa + Qb)
where a = 30 b = 1 and C = 3.
Leader's output = (a + Cb - 2Ca)/2b
Leader's output = (30 + 3 - 3*2)/2
= 13.5 units.
Reaction function of firm B,
Qb = 30 - 3/2
= 13.5 - 1/2*13.5
= 6.75 units.
P = 30 - (13.5 - 6.75)
= $9.75
Therefore, The price of this new drink in the long run if the industry is a Stackelberg duopoly is $9.75
