Total revenue=price *quantity

Marginal revenue is the total revenue in period 2 less total revenue in period 1. e.g. 2800-1600=1200

Quantity

Price, MC, MR

(b) The profit maximizing quantity of oil produced by the firm is 76 and price charged is $55. This is because there are no imports and exports so the market is more-or-less like a monopoly. The MR=MC is met at quantity 76 but the corresponding price charged is $55.

(c) The allocation is inefficient. This is because prices charged are above the marginal cost implying that the consumer welfare is reduced.

(d)

Consumer surplus =

Producer surplus =0

This is because the MC curve (whose rising portion should give the supply curve) is constant so the firm is experiencing constant marginal costs. Thus, the producer surplus is zero.

(e) They would charge price of $30 and quantity would be 120. This is because under perfect competitive conditions the firm would be guided by the P=MC condition.

(f) The consumer surplus would become

The producer surplus would not change because the still are constant marginal costs.

(b) I will choose to study. If I chose not to study, the classmates will study and I will fail. They will not choose not-study because they will not want to fail. This is a dominant strategy because it strictly reflects what will be done. At no time will not-study be chosen.

(c) They will study. This is because if they chose not to study I will study and they will fail. They will not choose not-study because they know both of us will fail. Studying strictly dominates not-studying.

(d) The Nash Equilibrium is (Study, Study). This is because no other equilibrium promises an equilibrating choice than this one. This is not a prisoner’s dilemma. In the prisoner’s dilemma, one party’s action may harm the other so that there ends up being no equilibrating choice. In this case there is a common choice which improves the welfare of both the parties ADDIN EN.CITE <EndNote><Cite><Author>Hal Varian</Author><Year>2006</Year><DisplayText> (Varian, 2006)</DisplayText><record><ref-type name="Book">6</ref-type><contributors><authors><author>Hal Varian</author></authors></contributors><titles/><title>Microeconomic Theory &amp; Applications</title><periodical/><dates><year>2006</year><pub-dates/></dates></record></Cite></EndNote> (Varian, 2006).
