Cross Elasticity of Demand (define)

Comparing % price change of one good to the % Quantity Demanded change of another. Will determine if goods are substitutes or complements to each other.
|

|
When Ei is negative the goods are
|
inferior

Complement Goods (define)
|
used to define goods when comparing Cross Elasticity. The increase of price for one good will decrease the Quantity Demanded of its complement.
Complement Goods = negative Cross Elasticity totals.

|
Ed Measures the _____ response to change in price
|
buyers

Applications of Price Elasticity of Demand (6)
|
1. Help explain revenue of Farmers in US and Developing Countries. 2. Formulate Taxation Policies. 3. Determine which Industries to run as Public Utilities. 4. Fix Prices for Monopolists. 5. Fix the rate of exchange. 6. Stablize Agricultural Prices.
|
|
If Ed is Inelastic and Price decreases, Total Revenue will
|
decrease
|
|
Determinants of Price Elasticity of Supply (7)
|
1. how quickly costs per unit rise as firms increase their output.
2. the availability of close input substitutes.
3. the amount of time available to adjust production to changing conditions
4. the degree of the market share controlled among producers
5. the expected future price of the product
6. the price of related inputs and related outputs
7. the speed of technological advances in production that can lower costs.
|
|
% change in Equilibrium Price and Supply have a(n) ________ relationship
|
indirect. When supply increases, Equilibrim Price decrease and vis versa
|
|
When calculating the % change of Equilibrium Price, an increase in Supply = ________ in price
|
decrease
|
|
Luxuries (define)
|
When the Income Elasticity of Demand is greater than 1 (and positive), then the good is a Luxury
|
|
If Ed is Inelastic and Price increases, Total Revenue will
|
increase
|
|
Elastic Price Elasticity of Supply (define)
|
1% change in Price = More than 1% change in Quantity Supplied
|
|
Ei measures the ________ response to change in ______
|
buyers....income
|
|
Inferior Goods (define)
|
When a decrease in Income Elasticity of Demand = an Increase in Demand the good is an Inferior Good.
Income Elasticity of Demand is negative.
(such as 99 cent store during recession)
|
|
Ex can be positive, negative or zero.True or False
|
True
|
|
Can you determine Price elasticity from the look of the slope?
|
No
|
|
Factors that determine Price Elasticity of Demand (5)
|
1. Number of substitutes: a product with substitutes will have an elastic Price Elasticity of Demand.
2. Necessity or Luxury: goods that are necessities (glasses, cigs) will have an Inelastic Price Elasticity of Demand, while Luxury Items (jewelry) will have an Elastic Price Elasticity of Deand.
3. Level of Income: poor: basic will be elastic; rich basics will be Inelastic because you will buy the amount you need regardless of price.
4. Price of Product relative to income. large portion of given income - elastic, small portion of income - inelastic (we do not price shop for salt).
5. Length of Period of Adjustment. Price change over long time = elastic; short term inelastic: people will pay higher gas prices short term, but will buy better mileage cars long term.
|
|
