what are determinants of the price elasticity of demand for a good?
time horizon definition of the market the availability of substitutes
the amount paid by buyers and received by sellers of a good, computed as the price of the good times the quantity sold
total revenue
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:
(Draw 2 different graphs) the curve will be sloping down (demand curve always slopes down) the demand curve for sony will fall because toshiba is cheaper and toshibas demand will increase (show the shift to right for toshiba)
List the 4 Determinants of Price Elasticity of Demand
-the larger the number of close substitutes -if the good is a luxury -the more narrowly defined the market -the longer the time period

If people change their expectations
Is the price of gasoline elastic or inelastic in the short run? What about in the long run?
In the short run, gasoline is inelastic because it is a necessity. In the long run it becomes more elastic because people adjust their habits by walking to work, riding a bike, or driving a more fuel efficient vehicle.
The negative relationship between price and quantity demanded:
It applies to most goods in the economy Its represented by a downward sloping demand curve Its referred to as the law of Demand

an increase in the demand for brown sugar
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 much more sensitive to a change in price when given more time to react
a measure of the responsiveness of quantity demanded or quantity supplied to a change in one of its determinants
elasticity
Other things equal, the demand for a good tends to be more inelastic, the:
fewer available substitutes
A likely example of complementary goods for most people would be?
hamburgers and fries

how much people respond to changes in market conditions
Demand is said to be elastic if:
if buyers respond substiancially to a change in price
What kind of elasticity does gasoline have?
in the short run it is inelastic because it is a necessity
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
income elasticity of demand
The market demand curve
is the sum of the quantities demanded by all the buyers

it is probably elastic
For a good that is a luxury, demand..
it tends to be elastic
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 demand
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
price elasticity of supply

that is inelastic
How does the implantation of a minimum wage of $8.00 rather than $6.00 affect the supply of workers available for work? Explain:
the curve will be sloping up you will have an increase in the amount of workers because of the higher wage (must draw picture)
Quantity demanded falls as the price rises and rises as the price falls, so we say that:
the quantity demanded is negatively related to price
The price elasticity of demand measures how much:
the quantity demanded responds to a change in the price
According to the law of supply:
the supply curve for a good is upward sloping
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:
you'll also need two curves the demand curve will slope down the demand for hamburgers will shift to the right the demand for fries will also shift to the right Both goods shift to the right because they are complimentary goods (they go hand in hand together)
