Answer:
4400
Increase
c. An index of 10,000 corresponds to a monopoly firm with 100% market share
Explanation:
Here are the options to the last question
Why is the largest possible value of the Herfindahl index 10,000 ?
a. An index of 10,000 corresponds to 100 firms with a 1% market share each
b. An industry with an index higher than 10,000 is automatically regulated by the Justice Department
c. An index of 10,000 corresponds to a monopoly firm with 100% market share
HHI index = 60² + 20² + 20² = 4400
If one of the firms leaves the industry, the market share would be distributed between the two firms and this would cause the HHI index to increase as firm's concentration would increase
If only one firm operates in the industry, its market share would be 100% and its HHI index would be 100² = 10,000. For an industry to exist there has to be at least one firm operating in the industry,
I’m not pretty sure about this answer but in my opinion it’s B
Answer:
b. marginal cost curve above the average variable cost curve.
Explanation:
A perfect competitive indsutry is a characterised by many firms selling homogenous goods and services. Firms are price takers and there are no barriers to entry or exit of firms in the industry.
The supply curve of a perfectly competitive firm in the short run is the part of the marginal cost curve that lies above the average variable cost curve.
A perfect competition maximises profit where price equals marginal cost.

Answer:
The demand for Jim’s product is elastic
Explanation:
In this question, we are to calculate the price elasticity of demand for the product.
We proceed as follows;
The formula for calculating elasticity of demand is
e = [(Q2 - Q1) / {(Q1 + Q2) / 2}] / [(P2 - P1) / {(P1 + P2) / 2}]
Here, Q2 = 6000
Q1 = 8000
P2 = $250
P1 = $200
e = [(6000 - 8000) / {(8000 + 6000) / 2}] / [($250 - $200) / {($200 + $250) / 2}]
e = [(- 2000) / 7000] / [(50 / 225]
e = - 1.3
That means absolute value of e is 1.3.
So, as the absolute value of e is more than 1 (i.e., 1.3), that means the demand for the product is elastic.
