What is the law of demand?

As the price of a good increases, the quantity demanded increases.

As the price of a good decreases, the quantity demanded increases.

As the price of a good increases, the quantity demanded decreases.

As the price of a good decreases, the quantity demanded decreases.

Which of the following is NOT a determinant of demand?

Tastes and preferences

Income

Price of substitute goods

Price of the good itself

What is the formula for calculating total revenue?

Total Revenue = Price × Quantity

Total Revenue = Price ÷ Quantity

Total Revenue = Price + Quantity

Total Revenue = Quantity - Price

In the long run, which factor can a firm adjust to achieve optimal production?

Number of workers

Size of the factory

Output level

Market demand

What is the main characteristic of a perfectly competitive market?

High barriers to entry

Homogeneous products

Few sellers dominating the market

Control over market price

What is a price ceiling?

A legal minimum price for a good or service.

A legal maximum price for a good or service.

A government subsidy provided to producers.

A tax imposed on consumers.

What is marginal cost?

The additional cost of producing one more unit of a good.

The total cost of producing all units of a good.

The fixed cost of producing one unit of a good.

The average cost of producing one unit of a good.

What is the difference between explicit and implicit costs?

Explicit costs are monetary payments while implicit costs are opportunity costs.

Explicit costs are opportunity costs while implicit costs are monetary payments.

Explicit costs are long-term costs while implicit costs are short-term costs.

Explicit costs are fixed costs while implicit costs are variable costs.

What is the definition of economies of scale?

When long-run average total cost decreases as output increases.

When long-run average total cost increases as output increases.

When short-run average total cost decreases as output increases.

When short-run average total cost increases as output increases.

#10

What is the main difference between perfect competition and monopolistic competition?

Number of firms

Nature of products

Pricing strategy

Barriers to entry

#11

What does the short-run average variable cost curve represent?

The average variable cost of production at different levels of output.

The total variable cost of production at different levels of output.

The average fixed cost of production at different levels of output.

The total fixed cost of production at different levels of output.

#12

What is the profit-maximizing rule for a perfectly competitive firm in the short run?

Produce where marginal revenue equals marginal cost.

Produce where total revenue exceeds total cost by the greatest amount.

Produce where average revenue equals average total cost.

Produce where marginal cost is at its minimum.

#13

What is the relationship between average total cost (ATC) and marginal cost (MC) when ATC is at its minimum?

ATC is equal to MC.

ATC is greater than MC.

ATC is less than MC.

ATC is unrelated to MC.

#14

What is the relationship between marginal cost (MC) and average variable cost (AVC) when MC is below AVC?

MC is increasing.

MC is decreasing.

MC is above AVC.

MC intersects AVC.

#15

What is the long-run supply curve for a perfectly competitive firm?

A horizontal line at the minimum point of the average variable cost curve.

A horizontal line at the minimum point of the average total cost curve.

A positively sloped line intersecting the minimum point of the average total cost curve.

A vertical line intersecting the minimum point of the average total cost curve.
