a) Find ABC’s average fixed costs, average variable costs, average total costs and marginal costs.

b) Since ABC is charging the customers at the price of $50, it seems that the company cannot make a profit. The owner decides to shut down operations. What are ABC’s profits/losses? Should the owner shut down operations? Explain.

c) Economic adviser suggested that it is better to produce unit of output, because marginal revenue equals marginal cost at the quantity. What are the ABC's profit /losses at the level of production? Was this the best decision? Explain.

Assuming that there are two types of radios on the market: good radios and bad radios. Of the firms that manufacture radios, 50% produce good radios and 50% produce bad radios. A good radio does not break for five years, while a bad radio has a 50% chance of breaking when it is first used. If the bad radio does not break immediately, it works for five years, just like the good radio. A good radio is worth $100 to consumers, and a bad radio is worth nothing.

a) What is the maximum price any consumer would be willing to pay for a radio if both types of firms produce radios? (1 mark)

b) If it costs $55 to manufacture each radio, will any firms want to produce radios?
 


c) If it costs $50 to manufacture each radio, which firms will want to produce radios?
 


d) Suppose that it costs $50 to manufacture each radio and $20 to repair a broken radio. Also suppose that the firms that produce good radios give a warranty in which they promise to repair any radio that breaks within five years of purchase. If the price of radios were to rise above $50, which type of firm would issue a warranty? If the price rose to $60, which type of firm would offer a warranty? Can warranties signal quality? What is the equilibrium price for radios in the market? 


Thank you for your generous help which would enlighten my knowledge on this subject and exercise.
