Question 1

The supply curve illustrates that firms:

Accepted Answer

The supple curve is upward sloping, reflecting the fact that as price rises, so does the quantity supplied.

Question 2

Suppose that the market price for hot dogs sold by street vendors has just risen from $4.50 to $5.00, and that in response Curly has now begun operating a hot dog cart. We can assume that Curly's reservation price for hot dogs is:

Accepted Answer

Curly did not want to sell hot dogs at $4.50, so his reservation price must be more than $4.50, but since he is willing to sell for $5.00, his reservation price cannot be more than $5.00.

Question 3

Refer to the figure below. If the price is $4 today and there is no change in either supply or demand, one would expect the price in the future to be:

Accepted Answer

At a price of $4, the quantity demanded is greater than the quantity supplied, so price will rise.

Question 4

If price is above the equilibrium price, then there will be:

Accepted Answer

If price is above the equilibrium price, the quantity supplied will be greater than the quantity demanded.

Question 5

When a market is in equilibrium:

Accepted Answer

There is neither excess demand nor excess supply when the market is in equilibrium.

Question 6

Jessica's marginal cost for producing a pitcher of lemonade is $0.25. Therefore, $0.25 is her:

Accepted Answer

A seller's reservation price is the smallest dollar amount for which a seller would be willing to sell an additional unit. A seller's reservation price is generally equal to the seller's marginal cost of producing an additional unit of output.

Question 7

The quantity that sellers wish to sell tends to ______ as price increases, and so the supply curve is ______ sloping.

Accepted Answer

As price increases, so does the quantity supplied, implying that the supply curve slopes upward.

Question 8

Which of the following is NOT a characteristic of a market in equilibrium?

Accepted Answer

Even when the market is in equilibrium, sellers would be pleased to receive a higher price and buyers would be happy to pay a lower price.

Question 9

Refer to the figure below. At a price of $3, there will be:

Accepted Answer

At a price of $3 buyers will want to buy 7 units and sellers will want to sell 2 units, a difference of 5 units.

Question 10

Refer to the figure below. At a price of $9, there will be:

Accepted Answer

At a price of $9 buyers will want to buy 1 unit, and sellers will want to sell 6 units, a difference of 5 units.

Question 11

If there is an excess supply of sport utility vehicles, then:

Accepted Answer

Excess supply occurs when the quantity supplied exceeds the quantity demanded.

Question 12

The price of bananas will increase in response to:

Accepted Answer

If the quantity of bananas demanded exceeds the quantity supplied, then price will rise.

Question 13

Refer to the figure below. The equilibrium price is ______, and the equilibrium quantity is ______.

Accepted Answer

The equilibrium quantity and price of a product are the values that correspond to the intersection of the supply and demand curves.

Question 14

Excess demand occurs:

Accepted Answer

Excess demand occurs when price is below the equilibrium price, so that the quantity demanded is greater than the quantity supplied.

Question 15

Equilibrium price and quantity are determined by:

Accepted Answer

Equilibrium results from the interaction of buyers and sellers.

Question 16

When a slice of pizza at the student union sold for $2, Moe did not purchase any. When the price fell to $1.75, Moe purchased a slice each day for lunch. Thus, we can infer that Moe's reservation price for a slice of pizza is:

Accepted Answer

A buyer will purchase an item if, and only if, its price is less than or equal to the buyer's reservation price. Since Moe buys a slice of pizza for $1.75, his reservation price must be at least $1.75, and since he does not buy a slice of pizza for $2.00, his reservation price must be less than $2.00.

Question 17

A seller's reservation price is generally equal to:

Accepted Answer

A seller's reservation price is the smallest dollar amount for which a seller would be willing to sell an additional unit, which is generally the same as their opportunity cost of producing an additional unit.

Question 18

A seller's reservation price is generally equal to:

Accepted Answer

A seller's reservation price is generally equal to the seller's marginal cost.

Question 19

As the price of a good rises:

Accepted Answer

At higher prices, more sellers find that the price is greater than their opportunity cost of producing the good.

Question 20

When the current price of a good is below the equilibrium price:

Accepted Answer

If, at the current price, there are more buyers who want to buy a good than there are sellers who wish to sell it, then frustrated buyers will have an incentive to offer to pay sellers a higher price to obtain the good.

Quiz 2: Supply and Demand

The supply curve illustrates that firms:

Suppose that the market price for hot dogs sold by street vendors has just risen from $4.50 to $5.00, and that in response Curly has now begun operating a hot dog cart. We can assume that Curly's reservation price for hot dogs is:

Refer to the figure below. If the price is $4 today and there is no change in either supply or demand, one would expect the price in the future to be:

If price is above the equilibrium price, then there will be:

When a market is in equilibrium:

Jessica's marginal cost for producing a pitcher of lemonade is $0.25. Therefore, $0.25 is her:

The quantity that sellers wish to sell tends to as price increases, and so the supply curve is sloping.

Which of the following is NOT a characteristic of a market in equilibrium?

Refer to the figure below. At a price of $3, there will be:

Refer to the figure below. At a price of $9, there will be:

If there is an excess supply of sport utility vehicles, then:

The price of bananas will increase in response to:

Refer to the figure below. The equilibrium price is , and the equilibrium quantity is .

Excess demand occurs:

Equilibrium price and quantity are determined by:
