Q

What are substitute goods

A

Goods that are alternatives to eachother

E.g. increase in price in one will increase demand in the other and vice versa

Q

What is derived demand

A

Demand for a good or factor of production used in making another good or service

(E.g increase in demand for fencing -> increased derived demand for wood)

Q

What does it mean if PED > 1

A

It is elastic

A percentage change in price will cause a small percentage change in qty demanded

Q

What does it mean when PED is between 0 and 1

A

It means it is inelastic

A percentage change in price will cause a larger percentage change in qty demanded

20
Q

What does it mean when PED = 0

A

It is perfectly inelastic

Any increase in price has no effect on demand

21
Q

What does it mean if PED = ± infinity

A

Perfectly elastic demand

Any increase in price will cause

22
Q

What does it mean If PED = ± 1

A

Unit elasticity

The percentage changes are equal

23
Q

What is income elasticity of demand

A

How much demand changes for a good with a change in real income

24
Q

What is the formula for YED

A

YED = percentage change in quantity demanded for a good / percentage change in real income

25
What is cross elasticity of demand (XED)
Measure of how quantity demanded of one good responds to a change in price of the other
26
What is the formula for XED
XED = percentage change in quantity demanded of good A / percentage change in price of good B
27
What are the factors that influence elasticity of demand
- substitutes (the more substitutes, the more price elastic) - type of good (e.g. essentials, cannot be postponed) - percentage of income spent on good
28
What type of good has a positive YED
Normal goods Incomes rise, demand increases
29
What type of good has a negative YED
Inferior goods Incomes rise, demand falls
30
What type of good has a positive XED
Substitute goods
31
What type of goods have a negative XED
Complement goods
32
What are elasticities of demand useful for
Sales forecasting Telling firms what to do in certain situations
33
What is supply
The quantity of a good or service thst producers supply to the market at a given price, at a particular time
34
What are marginal firms
Firms that are just breaking even
35
What causes shifts in supply
Changes in cost of production Improvements in technology Changes in the productivity of the factors of production
36
What is joint supply
When the production of one good or service involves the production of another E.g. if the price of the product increases, then supply of it and any other join products increased
37
What does price elasticity of supply (PES) measure
Measure of how the quantity supplied of a good responds to a change in price
38
What is the formula for PES
PES = percentage change in quantity supplied / percentage change in price
39
Why is a high PES important to firms
Important as firms aim to respond quickly to changes in price and demand So they must keep their supply elastic (PES >1)
40
What are perishable goods
E.g. fresh fruit Inelastic supply as cannot be stored long
41
What is market equilibrium
When demand = supply
42
What do supply and demand determine in a free market
They determine the equilibrium
43
What is excess supply
When the quantity supplied to a market is greater than the quantity demanded
44
What is excess demand
When the demand for a good or service is greater than its supply
45
What is a competitive market
When there is a large number of buyers and sellers No single consumer or producer can influence the allocation of resources by the market
46
What is a price mechanism
The means by which decisions of consumers and businesses interact to determine the allocation of resources
47
What is consumer surplus
The difference between the price that a consumer is willing to pay for a good and the price that they actually pay E.g. someone is prepared to pay £10 for a good and bought it for £8 then that is a consumer surplus of £2.
48
What is producer surplus
The difference between the price a producer is willing to supply a good or service at and the price they actually receive for it E.g. equilibrium price of a good is £15, but a supplier is able to sell it for £10. The producer surplus is £5
49
Is price elastic or inelastic in the short run
Price inelastic Difficult to increase production in short run as capital is fixed
