If a person only occasionally buys a cup of coffee, his demand for coffee is probably:

Elastic

Hamburgers and French fries

If Francis experiences a decrease in his income, we would expect that, as a result, Francis's demand for:

How much Quantity Demand responds to a change in the price

If buyers respond substantially to the change in the price

The negative relationship between price and quantity demanded:

It's referred to as the law of demand, it has a downward sloping curve, it applied to most goods

The law of demand says that:

Price goes up, quantity demand goes down; Price goes down, quantity demand goes up

Toshiba just introduced a 32" plasma screen TV for $800. Sony offers the same size TV for $900. What will happen to the demand of Sony's TVs based on Toshiba's new price. Explain:

QD for Sony's TV will fall because of Toshiba's cheaper price

For most people, you cannot eat a hamburger without french fries. If the price of hamburgers is decreasing, what happens to the quantity demanded of hamburgers? What happens to the demand of french fries? Explain:

QD for hamburgers will increase because of the cheaper price, french fries would also increase because they are COMPLIMENTARY GOODS

Quantity demanded falls as the price rises and rises as the price falls, so we say that:

QD is negatively related to the price

10. The market demand curve:

Represents the sum of the quantities demanded (QD) by all the buyers at each price of the good

Suppose you make jewelry. If the price of gold falls, we would expect you to:

That you'd be willing to produce more jewelry than before at each possible price

Elasticity

The ability of a material to bounce back after being disturbed

Which of the following is not a determinant of the price elasticity of demand for a good? (these will be the ones that are right)

Time Horizon, Definition of the market, the availability of close substitutes.

You love peanut butter. You hear on the news that 50 percent of the peanut crop in the South has been wiped out by drought, and that this will cause the price of peanuts to double by the end of the year. As a result:

Your demand for peanut butter will increase TODAY

Total Revenue

the total amount of money a firm receives by selling goods or services

- As price goes up, QS goes up - As price goes down, QS goes down

A public service announcement run on TV encouraging people to walk or ride their bikes

Brown sugar demand would increase, white sugar demand would decrease

Holding all other forces constant, when the price of gasoline rises, the number of gallons of gasoline demanded would fall substantially over a ten-year period because:

Buyers tend to be more sensitive to a change in price when given more time to react.

Income Elasticity of Demand

a measure of how much the quantity demanded of a good responds to a change in consumers' income, computed as the percentage change in quantity demanded divided by the percentage change in income

Price Elasticity of Demand

a measure of how much the quantity demanded of a good responds to a change in the price of that good, computed as the percentage change in quantity demanded divided by the percentage change in price

Price Elasticity of Supply

a measure of how much the quantity supplied of a good responds to a change in the price of that good, computed as the percentage change in quantity supplied divided by the percentage change in price

Each of the following is a determinant of demand except: (the ones below we need to know)

a. Taste b. Expectations c. Prices of related goods
