24
Q

What does PED mean and what does it measure

A

Price elasticity of demand - Measures the sensitivity of the quantity demanded of a good to a change in its price

25
What does YED mean and what does it measure
Income elasticity of demand - Measures the sensitivity of the quantity demanded of good to a change in consumer income
26
What does XED mean and what does it measure
Cross price elasticity of demand - Measures the sensitivity of the quantity demanded of good X to a change in the price of good Y
27
What does PES mean and what does it measure
Price elasticity of supply - Measures the sensitivity of the quantity supplied of a good to a change in its price
28
What is the PES of most goods?
Positive
29
What elasticity of demand are inferior goods always?
Negative YED
30
How do you calculate the percentage change in quantity supplied of a good following a change in price
Multiply the percentage change in price
31
What is an essential feature of an inferior good
YED is negative
32
Indirect tax on the production of a good will have no effect on price if demand is what
Perfectly elastic
33
What is a market?
A market is a voluntary meeting of buyers and sellers. It does not have to be a physical place.
34
What are some factors of a competitive market
- Large number of buyers and sellers - Good market information - Low barriers to entry and exit - Price takers
35
What is Demand
Demand is the quantity of a product consumers are willing and able to buy at different prices in a specified time period
36
What is effective demand
When a consumer's' desire to buy a product is backed up by an ability to pay for it
37
What factors can affect demand
- Consumer tastes and preferences - Income available to the customer - Prices of other goods and services ( Substitute and complementary goods) - Interest rates - Consumer population
38
What is the income effect
at lower prices, consumers can afford to purchase more with their income
39
What is the substitution effect
a fall in price makes one good relatively cheaper than a substitute
40
What causes an outward shift in demand
- Rise in real income - Increase in price of substitute good - Fall in price of complementary good - Change in consumer preference - Increase in population - Fall in interest rates - Rise in consumer confidence - Social changes that affect total demand for that product
41
What is a substitute good and an example
Goods in competitive demand that can be replaced for another product e.g Buses and cars
42
What is a complementary good and an example
Goods with joint demand, a rise in the price of a complement to good X should cause a fall in demand for X e.g iPhones and AirPods
43
What changes demand for normal goods
Income (A rise in income= more demand, A fall in income= less demanded)
44
Examples of inferior goods
Washing powder and pot noodles
45
What is substitutability
Number of close substitutes for a good and the uniqueness of the product in the market
46
What factors can determine whether a good is elastic or inelastic
- Substitutability - The % of a consumers income - Is it a necessity or luxury
47
What is supply
Supply is the quantity of a good or service that a producer is willing and able to supply onto the market at a given price in a given time period
48
What is the basic law of supply
the market price of a commodity rises, so producers expand their supply onto the market
49
What causes a shift in market supply
- Changes in production costs (Wages, price of raw materials, energy bills) - Government taxes and subsidies - Externtal shocks - Production technologies - New producers in market - Change in objectives - Change in substitute prices in production
50
What is equilibrium
Demand and supply are the same
51
What is equilibrium price also known as
Market-clearing price
52
Why might market demand shift to the right
- A rise in the price of a substitute or a fall in the price of a complement - An increase in consumers’ income or wealth - Changing consumer tastes and preferences in favour of the product - A fall in interest rates - A rise in consumer confidence
53
Why might market supply shift to the right
- A fall in the costs of production - A government subsidy to producers that reduces their costs for each unit supplied - A fall in the price of a substitute in production - improvement in technology (higher productivity and efficiency) - The entry of new suppliers (firms) into the market
54
What is derived demand and an example
when a product is demanded for use in the production of another product. E.g the housing market (construction of new homes rises, so too does the demand for materials used)
55
What is composite demand and an example
when you demand a good for more than one use. E.g crude oil is demanded for petrol and plastic
56
What is joint supple and an example
when a rise in the output of one product leads to a rise in the supply of the other product E.g more Sheep supplies more wool, meat and skin
57
What is latent demand and an example
willingness to purchase a good, but where the consumer lacks the real purchasing power to be able to afford the product E.g a yacht
