Answer #1

As given good is homogeneous ,so both firm's good will same and whichever firm charge lower price it will capture entire market.

Given MC1=10

MC2=5

So if firm2 best move is to charge price 10$ or less ,so thay firm 1 don't prpduce anything and it will capture entire Market.

On other hand firm 1 best move is to charge lowest possible price Equal to 10 and at this price it will be indifferent between producing and don't produce as in both case he will earn zero Profit.

So firm 2 charges P=10 and firm 1 doesn't operate ,so entire Market caotured by firm 2.

Q1=0

Q2=Q=110-10=100

Profit of firm 1=0

Profit of firm 2=(p-MC)*Q1=(10-5)*100=500

    4. Homogenous product Bertrand. Suppose that the demand for marbles is given by Q- 80 - 5P, where Q is measured in bags of marbles. There are two firms that supply the market, and the firms produce identical marbles (i.e., they are homogenous products). Firm 1 has a constant marginal cost of $10.00/bag, while firm 2 has a constant marginal cost of S5.00/bag. The two firms compete in price. In Nash Equilibrium, what prices will the two firms set? How...

    Q4. There are two firms A and B in a homogenous product industry. Inverse demand is P = 120 Q where Q is the combined output of the firms. Firm A has a marginal cost of 0 and firm B has a marginal cost of 10. There is an infinite sequence of periods in which firms simultaneously set prices. In this question we will consider whether the following collusive strategies with trigger strategy punish- ments are a subgame perfect Nash...
