HOW MARKETS WORK SHEET QUESTIONS Flashcards
What is the main objective of consumers when making economic decisions?
It is assumed that the main objective of consumers is to maximise utility./ Demand backed by an ability to pay.
What is the main objective of producers when making economic decisions?
It Is assumed that producers want to maximise profit.
What is meant by effective demand?
Effective demand, is the level of demand at the current price level.
What are the main determinants of demand?
(4 reasons)
Income, tastes and preferences, seasons, prices of substitute and complement goods, advertising.
Draw a demand curve.
see notes
What does a point on the demand curve the show?
A point shows the quantity demanded at that given price level.
What would cause a shift in the demand curve?
What would cause both shifts?
A change in demand will cause a shift on the demand curve.
An increase in demand will cause an outward shift.
A decrease in demand would cause an inward shift.
What would cause a movement on a demand curve.
What would cause movements.
A change in price at the given quantity will cause a movement.
An increase in price will cause a contraction in demand.
A decrease in price will cause an extension in demand .
Give an example of something that would shift the demand curve for potatoes to the right?
A shift to the right would mean an increase in demand. If the media announces that potatoes have a positive health effect the demand of potatoes would increase as a result.
Give an example of something that would shift the demand curve for potatoes to the left?
A shift of the demand curve to the left would mean a decrease in demand. This could be caused by it being found that harmful pesticides were being used on potatoes. This would decrease demand.
What is the definition of PED?
Price elasticity of demand
The responsiveness of demand to a change in price.
Formula change in quantity demanded(%)/ change in price (%).
What is YED?
Income elasticity of demand.
The responsiveness of demand to a change in disposable income.
Change in QD (%)/ Change in Y (%).
What is XED?
Cross elasticity of demand
The responsiveness of demand to a change in price of another good.
Change in QD (%)/ Change in price of good b (%)
Define normal good and link this to income elasticity?
A normal good is one that demand increases if income increases (positive YED).
Define an inferior good with income elasticity?
An inferior good is one where demand decreases if income increases.
Define a substitute good and link this to cross-price elasticity?
A substitute good is an alternative good. A substitute has a positive (XED).
Define a complement and link this to cross price elasticity?
A complimentary good is one that is used with or purchased at the same time as another good. Complement good has a negative (XED)
How do you calculate percentage change?
New-old/old x 100
What range of value is perfectly inelastic?
0
What range of value is inelastic?
0 to -1
What is the range of values for elastic?
-1 to -infinity
What is the range of values for perfect elasticity?
-infinity
What is the formula for calculating price elasticity of demand?
(%) change in quantity demanded/(%) change in price x 100
What is the formula for price elasticity of income?
(%) change in quantity demanded/ (%) change in income (y).
