1. The Herfindahl index: Suppose that three firms make up the entire bicycle manufacturing industry. One has a 40% market share,
alukav5142 [94]

Answer:

3400, Rise, C

Explanation:

1. Since there are just 3 firms and two already has a sum total of 70% (40+30), the third firm will have a market share of 30%

HHI= 40^{2}+ 30^{2}+30^{2}\\

HHI= 1600+900+900

HHI= 3400

2. Abe's Bikes with 30% leaves the market, if the two firms were to share Abe's market share equally (15+15), it will leave Firm A with 55% (40+15) and Firm B with (30+15) 45%

Therefore,

HHI= 55^{2}+45^{2}

HHI=3025+2025

HHI= 5050

A rise in HHI

3. C

An index of 10,000 corresponds to a monopoly firm with 100% market share.

Suppose that Italy and Portugal both produce cheese and wine. Italy's opportunity cost of producing a bottle of wine is 2 pounds
Lemur [1.5K]

Answer:

The correct answer is letter "A": Neither Italy or New Zealand.

Explanation:

Comparative advantage is the ability of an individual or organization to manufacture its products at a lower opportunity cost than its competitors. The scenario does not imply the individual has an absolute advantage. It actually means it sacrifices less to achieve that goal.

Thus, <em>Portugal has a lower opportunity cost than Italy in producing a bottle of wine. Portugal's opportunity cost is 1/2 while Italy's opportunity cost is 2. Neither Italy or New Zealand (or any other country not mentioned in the example) has a comparative advantage in producing wine</em>.

If a competitive firm is currently producing a level of output at which profit is not maximized, then it must be true that a. ma
kvv77 [185]

Answer:

a. Marginal revenue exceeds marginal cost.

Explanation:

<u>Note</u>: <u>The words "profit is not maximized" have been interpreted as, "the firm at current level of output earns profits, but not maximum profits it can earn." The answer provided herein is based upon this assumption.</u><u> </u>

Marginal revenue (MR) refers to the addition to total revenue when an additional unit of output is sold.

Similarly, marginal cost (MC) refers to the addition to total cost of production, when an additional unit is produced.

For an optimal level of production, and as a condition for profit maximization under perfect competition,

MR = MC and the marginal cost should increase post the level of output at which MR = MC.

If a competitive firm operates at a level wherein profits are not maximized, but the firm does earn profits, it indicates the stage of production wherein the marginal revenue exceeds the marginal cost.

Thus, as firm produces more and more units of output, it would reach a stage wherein marginal revenue would equal marginal costs and profits shall be maximized.
