1.3 (Introducing the market) Flashcards
1.3.1
What is demand?
the willingness and ability of a consumer to buy goods and services at a specific price
What happens to the demand curve if demand increases?
The curve shifts up and to the right
What happens to the demand curve if demand decreases?
The curve shifts down and to the left
Reasons for changes in demand (PASIFIC)
Population increase
Advertising increase
Substitute goods increase in price
Income increases
Fashion/trends
Interest rates decrease
Complementary goods decrease in price
What are normal and inferior goods?
Normal= as income rises demand rises
Inferior= as income rises demand falls
What is a demographic?
statistics about a population showing data
What is income?
money earned often from wages/salaries
What is a substitute good?
alternative products often provided by competitors
What is a complementary good?
products which tend to be used together
What is income elasticity?
The sensitivity of demand for a certain good to a change in the real income of consumers who buy that good
What is price inelastic?
The static quantity demanded of a good or service when its price changes
What causes movement along the demand curve and a shift in the demand curve?
Movement along = price changes
Shift= any factor other than price changes
What is demand curve contraction and expansion?
Contraction= price rises and quantity falls (up the curve)
Expansion = price falls and quantity rises (down the curve)
What are demand schedules and what are they used for?
+what is used to make these
A table that shows the quantity demanded of a good or service at different price levels.
Used to predict the earnings a particular product or company might make
+ demand curves
How is effective demand different from demand?
Demand = willingness to buy
Effective demand = willingness and ability to buy
What is a logical/rational consumer?
A consumer who will (in theory) make choices that bring the most satisfaction possible from their limited income
What is customer sovereignty?
the situation in an economy where the desires and needs of consumers control the demand and therefore the output of producers
1.3.2
What is supply?
+ what happens to this if price rises?
The quantity of a good or service that producers are willing and able to supply at a given price
+ the supply will rise
What causes movement along the supply curve?
What causes a shift in the supply curve?
A change in price
When there is a change in a factor other than price
What happens to the supply curve when price increases/ decreases?
Increase= move along supply curve (extension)
Decrease= move down the supply curve (contraction)
Which way does the supply curve shift when a non-price factor causes the supply to :
- increase?
- decrease?
Increase= to the right
Decrease= to the left
Which factors other than price can cause a shift in the supply curve? (PINTSWC)
Productivity
Indirect tax
Number of firms entering/leaving the market
Technology
Subsidies
Weather
Cost of production
What are subsidies?
sums of money given to producers usually by the government to encourage supply
What happens to supply if a factor besides price or quantity changes?
a new supply curve must be drawn (once this is created other determinants can be added)
What is an external shock?
+ what is sustainability?
An occurrence beyond a firm’s control which may affect costs
+ the ability to maintain or support a process continuously over time
What is the long run and what is the short run?
Long run: a situation where all the factors of production and costs are variable. (Allows firms to operate and adjust costs)
Short run: within a certain period in the future, at least one input is fixed while the others are variable
