What does the production possibility frontier (PPF) represent?

The maximum amount of goods and services an economy can produce with its existing resources and technology

The minimum amount of goods and services an economy can produce with its existing resources and technology

The total amount of goods and services an economy can produce regardless of resources and technology

The optimal allocation of resources and technology to maximize economic growth

What is the law of diminishing marginal utility?

As the quantity consumed of a good increases, the total utility increases at a decreasing rate

As the quantity consumed of a good increases, the total utility increases at an increasing rate

As the quantity consumed of a good decreases, the total utility decreases at a decreasing rate

As the quantity consumed of a good decreases, the total utility decreases at an increasing rate

Which of the following is a characteristic of an oligopoly market structure?

Many buyers and one seller

Many buyers and many sellers

Few sellers with significant market power

One buyer and many sellers

What is the formula to calculate price elasticity of demand?

Percentage change in quantity demanded / Percentage change in price

Percentage change in price / Percentage change in quantity demanded

Absolute change in quantity demanded / Absolute change in price

Absolute change in price / Absolute change in quantity demanded

What is the difference between accounting profit and economic profit?

There is no difference, they are the same

Accounting profit considers explicit costs, while economic profit considers both explicit and implicit costs

Economic profit considers explicit costs, while accounting profit considers both explicit and implicit costs

Accounting profit is calculated over the short run, while economic profit is calculated over the long run

What is the formula to calculate marginal cost?

Change in total cost / Change in quantity

Change in quantity / Change in total cost

Change in total cost / Change in output

Change in output / Change in total cost

#10

What is the difference between explicit costs and implicit costs?

There is no difference, they are the same

Explicit costs are monetary costs, while implicit costs are opportunity costs associated with the use of resources

Implicit costs are monetary costs, while explicit costs are opportunity costs associated with the use of resources

Explicit costs represent long-term costs, while implicit costs represent short-term costs

#11

What is the formula to calculate average revenue (AR)?

Total revenue / Quantity sold

Price / Quantity sold

Quantity sold / Total revenue

Price * Quantity sold

#12

What is the difference between economic efficiency and technical efficiency?

There is no difference, they mean the same thing

Economic efficiency refers to producing at the lowest possible cost, while technical efficiency refers to producing the maximum output with given inputs

Technical efficiency refers to producing at the lowest possible cost, while economic efficiency refers to producing the maximum output with given inputs

Technical efficiency is only concerned with maximizing profit, while economic efficiency considers societal welfare

#13

What is the Coase theorem?

It states that in a perfectly competitive market, firms will seek to maximize profit

It argues that government intervention is always necessary to correct market failures

It suggests that when property rights are well-defined and transaction costs are low, bargaining will lead to an efficient allocation of resources regardless of the initial allocation

It asserts that monopolies will always lead to higher prices and lower output

#14

According to game theory, what is a Nash equilibrium?

A situation where each player makes the best decision for themselves, given the decisions of the other players

A situation where all players cooperate to achieve the best possible outcome

A situation where one player dominates the decision-making process

A situation where all players make suboptimal decisions

#15

What is a Giffen good?

A good for which demand increases as income increases

A good for which demand decreases as income increases

A good for which the income elasticity of demand is negative

A good for which the cross-price elasticity of demand is positive

#16

What is price discrimination?

Setting different prices for different customers based on their willingness to pay

Setting the same price for all customers regardless of their willingness to pay

Setting prices lower for customers with higher income

Setting prices higher for customers with higher income

#17

What is the difference between perfect price discrimination and other forms of price discrimination?

There is no difference, they refer to the same concept

Perfect price discrimination involves charging each customer their maximum willingness to pay, while other forms of price discrimination involve charging different prices based on certain characteristics

Perfect price discrimination involves charging the same price to all customers, while other forms of price discrimination involve charging different prices to different customers

Perfect price discrimination only occurs in perfectly competitive markets, while other forms of price discrimination occur in imperfectly competitive markets
