1. In a competitive market, the market-determined price is $60. For a typical firm producing 100 units of output, short-run marginal cost is constant at $65, average total cost is $95, and average fixed cost is $30. Is this firm making the profit-maximizing decision? If not, what should it do?
a) No, it is not making the profit maximizing decision. In the short run, it should reduce its rate of production until its marginal cost is equal to $60.
b) Yes, it is making the profit-maximizing decision.
c) No, it is not making the profit maximizing decision. In the short run, it should increase its rate of production until its marginal cost is equal to $60.
d) No, the firm is not making the profit maximizing decision. It should shut down in the short run to minimize losses.

2. When price is greater than average variable cost but less than average total cost at the profit-maximizing level of output, a firm should
a) continue to produce the level of output at which marginal revenue equals marginal cost.
b) increase output to minimize its losses.
c) reduce output to the level at which price equals average variable cost to minimize its losses.
d) shut down to minimize its losses.

3. In a competitive market, the market-determined price is $25. For a typical firm producing 10,000 units of output, the firm's average cost reaches its minimum value of $25. Is this firm making the profit-maximizing decision? If not, what should the firm do?
a) No, it is not making the profit-maximizing decision. In the short run, it should reduce its rate of production because its marginal cost is not equal to $25.
b) Yes, it is making the profit-maximizing decision.
c) No, it is not making the profit-maximizing decision. In the short run, it should increase its rate of production because its marginal cost is not equal to $25.
d) No, it is not making the profit-maximizing decision. In the short run, it should reduce its rate of production until its average variable cost is equal to $12.

8. The following are the inverse demand curve and MR curves for a monopolistically competitive firm. P = 1000 - 2Q MR = 1000 - 4Q Where P is the price of the product and Q is the level of production. For the 200th unit of Q, MR is equal to _______ and demand is price ____________.

10. Assume a monopoly has the following demand schedule: Price........Quantity $20.............200 $15.............300 $10.............500 $5...............700 What can you say about the price elasticity of demand along the demand curve between $15 and $20?
a) Demand is price elastic.
b) Demand is price inelastic.
c) Demand is unitary elastic.
d) There is not enough information to tell.

11. Which of the following statements is correct?
a) Barriers to entry do not affect the industry structure.
b) Barriers to entry affect the competitiveness of an industry because they determine whether or not typical firms in an industry will face new competition if they are earning above normal returns on investment.
c) Barriers to entry are highest for monopolistic competition.
d) Barriers to entry can be achieved only through government mandate.

12. Which of the statements below concerning barriers to entry is FALSE?
a) They restrict entry into industries in which positive economic profits are being made.
b) They are somewhat lessened by the existence of patents.
c) They may be due to legal impediments such as licenses.
d) They may be due to a single firm controlling access to a natural resource or production process.

13. In comparing monopoly to a competitive market, which of the following is FALSE?
a) Market price will be higher under monopoly.
b) Equilibrium quantity will be higher under perfect competition.
c) Consumers will be worse off with the monopoly.
d) Employment will be higher under monopoly.

14. All of the following are possible characteristics of a monopoly except
a) there is a single firm.
b) the firm is a price taker.
c) the firm produces a unique product.
d) the existence of some advertising.

15. ZZZ, Inc. operates in a monopolistically competitive industry. Its demand curve can be written as P = 160 - Q and its short run total cost curve is equal to TC = 1000 + Q^2. What is the rate of output that maximizes ZZZ, Inc.'s short run profits?
a) 40
b) 0
c) 53
d) 20

1. In a competitive market, the market-determined price is $60. For a typical firm producing 100 units of output, short-run marginal cost is constant at $65, average total cost is $95, and average fixed cost is $30. Is this firm making the profit-maximizing decision? If not, what should it do?

Since marginal cost is constant in the given case. It is higher than the prevailing market price. So, it is not an optimal decision and firm should shut down in the short run.
Correct option is D. No, the firm is not making the profit maximizing decision. It should shut down in the short run to minimize losses.

2. When price is greater than average variable cost but less than average total cost at the profit-maximizing level of output, a firm should

Since price is greater than average variable cost, it means that it is operating above shut down point. So, correct option is A. continue to produce the level of output at which marginal revenue equals marginal cost.

3. In a competitive market, the market-determined price is $25. For a typical firm producing 10,000 units of output, the firm's average cost reaches its minimum value of $25. Is this firm making ...

Basic Concepts in Managerial Economics

Use the following general linear supply function to answer this question:
Qs = 40 + 6P - 8PI + 10F
Where Qs is the quantity supplied of the good, P is the price of the good, PI is the price of an input, and F is the number of firms producing the good.
If PI = $20 and F = 60 what is the equation of the supply function?

Qs = 400 + 6P
Qs = 40 + 8P
P = 480 + 6Qs
Qs = 480 + 6P
None of the above.

Use the following general linear supply function to answer this question:
Qs = 40 + 6P - 8PI + 10F
If PI = $20, F = 60, and the demand function is Qd = 600 - 6P the equilibrium price and quantity are, respectively,
P = $10 and Q = 640
P = $8 and Q = 326
P = $10 and Q = 540
P = $8 and Q = 640
None of the above

If the current price of a good is $10, market demand is Qd = 400 - 20P, and market supply is Qs = -50 + 10P, then
More of the good is being produced than people want to buy.
A lower price will increase the shortage.
At the current price there is excess demand, or a shortage, of 150 units.
Both b and c.
All of the above.

Yesterday's newspaper reported the results of a study indicating that people who eat more bananas are more attractive to the opposite sex. What do you expect to happen to the market price and quantity of bananas?
Price will decrease, quantity will decrease.
Price will decrease, quantity will increase.
Price will increase, quantity will decrease.
Price will increase, quantity will increase.

In which of the following cases must price always fall?
Demand increases and supply increases.

Demand decreases and supply increases.
Both c and d.

Consumer surplus
Is positive for all but the last unit purchased.
For a particular unit of consumption is computed by taking the difference between demand price and market price.
For all units consumed is the area below demand and above market price over all the units consumed.
Added to producer surplus provides a measure of the net gain to society from the production and consumption of the good.
All of the above.
