Solutions

Expert Solution

68.Ans: e) c and d

Explanation:

Differences between a perfectly competitive firm and a monopoly firm are;

  • The monopoly firm charges the highest per-unit price for its product, and the perfectly competitive firm does not.

  • The demand curve and the marginal revenue curve are the same for the perfectly competitive firm, but they are not the same for the monopoly firm.

Under perfect competition , the industry is the price maker whereas the firm is the price taker. It means there is an unique price in the market . Firms are not able to change the market price. They can sell or produce as much as they can at the prevailing market price.

So under perfect competition , Price = Marginal Revenue = Average Revenue ( P = MR = AR) and demand curve is horizontal.

Under monopoly market structure , firm is a price searcher.

69.Ans: e) all of the above

Explanation:

The following assumptions applies to both perfect competition and monopolistic competition;

  • There are many buyers and sellers
  • There is easy entry into and exit from the market
  • profit-maximizing behavior by firms in both market structures.

70.Ans: d) supply; leftward; increase; decrease

Explanation:

Resource X is necessary to the production of good Y. If the price of resource X rises, the cost of production will increase. So the supply curve for good Y will shift lefward or backward . As a result , the equilibrium price of Y will increase and  the equilibrium quantity of Y will decrease.

11. Sources of monopoly power A monopoly, unlike a perfectly competitive firm, has some market power. Thus, it can raise its price, within limits, without quantity demanded falling to zero. The main way monopolies retain their market power is through barriers to entry, which prevent other companies from entering monopolized markets and competing for customers. Consider the market for tanzanite. The mines for this blue-purple gemstone, found only in Tanzania, are owned by the local government. Given that no one...
