Microeconomics 2 Flashcards
What are the three types of economy?
Command economy
-Government makes the production decisions
Free Market
- The people and companies make production decisions
Mixed Economy
-Government make decisions in certain areas such as public services, but in other areas the people and companies can make production decisions
What are the factors that can affect demand?
- Prices of goods
- as prices rise, demand falls
Prices of other goods
- Substitute or complementary goods
Income
- If people have less disposable income demand for inferior goods may increase.
Taste/Fashion
- Demand rises if the product/service is fashionable
Other factors
- Population size and available credit
What is a contraction in a demand curve?
This is where prices increase, demand will decrease and will show an upward movement on the demand curve.
What is a expansion in a demand curve?
This is where prices are getting lower, demand will increase causing a downward movement on the curve
What is demand elasticity?
Refers to how responsive the market is to price
What does it mean if a products demand is elastic?
This means it is responsive, so if the price changes there can be a large movement in the demand for the product.
What does it mean if a products demand is inelastic?
Not very responsive, so if a price changes there will not be much change to the demand.
What is the ARC Method - non-average in demand and how is it calculated?
This is how you calculate Price Elasticity of Demand for particular goods/services.
Change in demand(%)/change in price(%)
How do you calculate the ARC Menthod in demand - Average
change in demand(%) - Versus average/Change in price(%) - Versus average
What are the factors affecting PED?
Substitutes - Availability of subs = more elasticity
Necessity or habit = Less elastic
Time frame = Things can be less elastic in the shirt term
Brand Loyalty = Less elastic
Proportion of income = If it is a small proportion of your income the product can be inelastic
Definition of the market - if there is fewer alternatives it will be less elastic.
What does values <1 mean in Price elasticity of demand?
Means the Product is inelastic or that its demand is relatively sensitive too price
What does values >1 mean in Price elasticity of demand?
Means the Product is elastic or that its demand is relatively sensitive too price
What are the factors that affect Supply?
Price
Price of other goods
Cost changes
Success of harvests
What does Expansion mean on a supply curve?
High prices = high supply and an upwards movement on the curve
What does contraction mean on a supply curve?
Low Prices = Low supply and a downward movement on the curve
What do positive changes in supply cause on a supply curve?
Rightward shift on the curve
What do negative changes in supply cause on a supply curve?
Shift to the left on the curve
What is the ARC Method - non-average in supply and how is it calculated?
Price Elasticity of Supply (PES)
Change in supply(%)/change in price(%)
What is the ARC Method - average in supply and how is it calculated?
change in supply(%) - Versus average/Change in price(%) - Versus average
What are the factors that influence responsiveness in price?
Time frame - harder to make change to supply in the short term
Factors of production - If more factors are required it is more difficult to make changes
Inventory levels
Competition
What happens if prices are above the equilibrium?
Creates more supply as companies will try make more profit, but will inevitable cause less demand causing a contraction in the demand curve.
What happens if prices are below the equilibrium?
Increases high demand but reduces the supply.
What is a market failure?
Market failure is the inability of a market to allocate resources in a way that maximises utility
What is the problem with public goods when it comes to market failures?
Problem – some goods (e.g. street lighting, police force) may not be produced
under a market system due to
– Non-excludability (“free-rider” problem)
– Non-rivalry
Solution – provided by the state, which hopefully benefits from economies of
scale. (Major argument for the need for taxation)
