Using Qd = 100 − 2P and Qs = 20 + 2P, enter the market equilibrium price in dollars. Enter a whole-dollar value with no dollar sign.
A firm's total product rises from 50 to 68 units when its labor force increases from 5 to 6 workers. What is the marginal product of the sixth worker? Enter a whole-number quantity of output.
The value of the next-best alternative forgone is called .
Demand for labor is because labor helps produce goods and services. The additional revenue generated by one more unit of an input is its .
Select all characteristics or examples that apply to a pure public good.

A negative cross-price elasticity identifies substitutes
- B
A positive cross-price elasticity identifies substitutes
- C
A per-unit tax generally increases the equilibrium quantity exchanged
- D
A tax can create deadweight loss by preventing mutually beneficial trades
A worker's marginal product is 8 units, the product sells for $25 per unit, and the wage is $180. Should the firm hire the worker? Calculate the worker's marginal revenue product and justify your answer using the hiring rule.
A per-unit tax is imposed in a market where demand is highly inelastic and supply is relatively elastic. Which side bears the larger share of the tax burden?
- A
Consumers, because demand is relatively inelastic
- B
Consumers, because supply is relatively elastic
- C
Sellers, because demand is relatively inelastic
- D
Sellers, because supply is relatively elastic
Which graph interpretation correctly describes a factory that pollutes a river without paying for the damage?
- A
MSC is above MPC, and market output exceeds socially efficient output
- B
MSC is below MPC, and market output is below socially efficient output
- C
MSB is above MPB, and market output exceeds socially efficient output
- D
MSB is below MPB, and market output is below socially efficient output
Select all correct statements about how an unregulated monopolist chooses output and price.
- A
Choose quantity where demand equals marginal cost, then set price equal to marginal cost.
- B
Choose quantity where marginal revenue equals marginal cost, then find price on the demand curve.
- C
Because the monopolist faces downward-sloping demand, marginal revenue lies below the demand curve.
- D
Choose quantity where average total cost is minimized, then set price equal to average total cost.
What does a point inside a production possibilities curve represent?
- A
It is unattainable with current resources and technology.
- B
It is attainable but productively inefficient.
- C
It is productively efficient and must be on the PPC.
- D
It represents economic growth caused by improved technology.

- A
True
- B
False
Which statement correctly describes competitive market equilibrium?
- A
The market always sets the highest price consumers are willing to pay.
- B
The equilibrium price is where quantity demanded equals quantity supplied.
- C
A surplus occurs whenever quantity demanded equals quantity supplied.
- D
The equilibrium quantity is always zero when prices are flexible.
A per-unit tax is imposed in a market where demand is relatively inelastic and supply is relatively elastic. Which outcome is most likely?
- A
Sellers bear more because sellers legally remit the tax.
- B
Buyers bear more because demand is relatively more inelastic.
- C
Buyers and sellers always split the tax equally.
- D
Sellers bear more because supply is relatively elastic.
Which procedure correctly describes how an unregulated monopolist chooses its profit-maximizing outcome?

Produce where price equals average total cost, then charge marginal cost.
- B
Produce where demand equals marginal cost, then charge the market price.
- C
Produce where marginal revenue equals marginal cost, then use demand to find price.
- D
Produce where average variable cost is minimized, then charge the monopoly price.

- A
True
- B
False
True or false: A binding price floor set above equilibrium creates a surplus.

True
- B
False

A student can either work one additional hour for $18 or study for an exam. The expected academic benefit of studying is valued at $25. Assuming no other relevant costs or benefits change, which choice follows the marginal decision rule?
- A
The student should work because $18 is greater than $7.
- B
The student should study because the net benefit is $7.
- C
The student is indifferent because the academic benefit equals the opportunity cost.
- D
The student should do neither because the resources are scarce.
An economy is producing at a point inside its current production possibilities curve. What does this point indicate?

It is unattainable and reflects economic growth.

A consumer receives 24 units of marginal utility from one more unit of good A, which costs $4, and 12 units of marginal utility from one more unit of good B, which costs $3. If the consumer can reallocate spending, what should the consumer do to increase total utility?
- A
Buy more of good A because its marginal utility per dollar is higher.
- B
Buy more of good B because its total marginal utility is lower.
- C
Buy equal amounts of both goods because their prices are different.
- D
Keep spending unchanged because marginal utility cannot be compared across goods.
