dse 2012 Q.23

QUESTION 23. Consider a homogenous goods market with the demand
function Q = 30􀀀P, where Q and P denote quantity and price respectively.
There are two rms playing a price game in the following manner: rm 1
quotes a price and then rm 2 chooses a price. When they charge the same
price they share the market equally and otherwise the market demand goes
to the rm charging lower price. Firm 1 has a capacity constraint at the
output level 5 units such that upto ve units the marginal cost of production
is Rs 3 per unit of output, however beyond 5 units it cannot produce any
output. Firm 2 does not have any capacity constraint, it can produce any
amount with the marginal cost Rs 6. What would be the equilibrium price
in the market?

Re: dse 2012 Q.23

yushi.
Ans- 6
Homogenous products implies perfect competition.. supply=MC.
AT MC=3, Q=30-3=27 > 5 So Firm 1 cannot produce..
at MC=6 Q=30-6=24. Firm will produce 24 units at price 6.
