the measurement of slope is sensitive to the units chosen for price and quantity

supply

the number of units that sellers will offer for sale at various prices

Assume that an individual spends his income on sweaters and shirts. If the price of a sweater increases:

the opportunity cost of buying sweaters increases.

The slope of a budget constraint represents:

the opportunity cost of one good in terms of another.

If the demand for a steak is unit elastic, then

the percentage change in quantity demanded is equal to the percentage change in price

If the demand for cell phone service is inelastic, then

the percentage change in quantity demanded is less than the percentage change in price (in absolute value)

Cross-price elasticity of demand measures

the percentage change in quantity demanded of one good caused by a percentage change in the price of another good

The price elasticity of supply is equal to

the percentage change in quantity supplied divided by the percentage change in price

The attainable production points on a production possibilities curve are

the points along and inside the production possibility frontier

One would speak of a change in the quantity of a good supplied, rather than a change in supply, if

the price of the good changes.

If a good has a price elasticity of demand equal to 0, ________. . the quantity demanded is completely unaffected by a change in its price . the demand curve of the good is upward sloping . the percentage change in quantity demanded for the good will be greater than the percentage change in its price . the smallest increase in its price causes consumers to stop consuming it completely

the quantity demanded is completely unaffected by a change in its price

The Law of Demand states that:

the quantity demanded of a commodity varies inversely with the price of the commodity

If the demand and supply curves for a commodity both shift to the left by the same amount, then in comparison to the initial equilibrium, the new equilibrium will be characterized by

the same price and a lower quantity

Economic surplus is equal to

the sum of consumer surplus and producer surplus

In​ 2004, hurricanes destroyed a large portion of​ Florida's orange and grapefruit crops. In the market for citrus​ fruit,

the supply curve shifted to the left resulting in an increase in the equilibrium price.

Assume that the price for swimming pool maintenance services has risen and sales of these services have fallen. One can conclude that

the supply of swimming pool maintenance services has decreased

When buyers and sellers operate in a competitive market, it is because

the value to consumers is at least as great as the cost to produce

A demand curve shows . the willingness of consumers to substitute one product for another product. . the relationship between the price of a product and the demand for the product. . the willingness of consumers to buy a product at different prices. . the relationship between the price of a product and the total benefit consumers receive from the product.

the willingness of consumers to buy a product at different prices

A correlation between two variables implies that:

there is a mutual relationship between both the variables.

Every individual, no matter how rich or poor, is faced with situations that require _________.

trade-offs

(T/F) A surplus occurs when the actual selling price is above the market equilibrium price

true

(T/F) An increase in the quantity of a product supplied is caused by an increase in the price of the product

true

(T/F) Because the demand for illegal drugs is inelastic and the supply is elastic, policies that reduce supply in the illegal drug market do not reduce equilibrium quantity very much

true

(T/F) In response to a surplus the market price of a good will fall; as the price falls, the quantity demanded will increase and quantity supplies will decrease until equilibrium is reached.

true

(T/F) Marginal cost is the additional cost to a firm of producing one more unit of a good or service.

true

(T/F) Producer surplus is the difference between the lowest price a firm is willing to accept for a product and the price it actually receives for the product

true

(T/F) The total surplus measures the net benefit to society as a whole

true

Making optimal decisions "at the margin" requires

weighing the costs and benefits of a decision before deciding if it should be pursued.

A decrease in the equilibrium price for a product will result

when there is an increase in supply and a decrease in demand for the product.

If the demand for a product is perfectly inelastic, a decrease in the price of the product

will decrease total revenue

We can show economic​ inefficiency:

with points inside the production possibilities frontier

We can show economic​ efficiency:

with points on the production possibilities frontier.

When quantity demanded is completely unresponsive to​ price, what is the value of price elasticity of​ demand?

zero
