Question 1:

(a) What market structure is used to benchmark allocative efficiency, and why do we use it? Illustrate and explain using a diagram

(b) Why and how do monopolistically competitive firms fail to achieve allocative efficiency? Illustrate and explain using a diagram.

Question 2:

(a) You are examining and reporting on the market performance of a very small number of firms that are known to often collude in setting output prices and quantities. Illustrate and explain using a diagram what affect this behaviour is most likely to have on the allocation of factors of production.

(b) What will happen if one of these firms cheats on the others in some way? Illustrate and explain using a diagram.

Question 3:

(a) Illustrate and explain using diagrams how a single seller within the market can maintain an inefficient allocation of resources;

(b) Are there any advantages to a single market seller and how do they compare to its perceived disadvantages.

Question 4:

(a) Assuming a constant wage rate, illustrate and explain using a diagram, how a firm's marginal costs of production are at a minimum when its marginal product is at a maximum;

(b) Illustrate and explain using a diagram how a firm's long-run average cost curve comes into existence from a multi-plant operation;

Question 5:

Illustrate and explain using diagrams; two of the market mechanisms that are used for controlling pollution as an externality.

YED= +0.6 and YED= -2.6

(d) Interpret the following Cross-Price Elasticities of Demand (XED) and explain the relationship between these goods.

XED= + 0.64 and XED= -2.6

Question 9:

The following diagram shows the cost curves of a firm under perfect competition.
