Q

What is an INFERIOR GOOD?

A

Q

What factors determine PRICE ELASTICITY OF DEMAND?

A
  • Substitutability
  • Percentage of income
  • Necessities or luxuries
  • The ‘width’ of the market definition
    (The wider the market, the lower the price elasticity of demand)
  • Time
19
Q

What is meant by INCOME ELASTICITY OF DEMAND?

A

How demand responds to a change in income

20
Q

Question!
Peoples average income fall from £1000 to £600. As a result, demand for potatoes increase from 1m tonnes to 1.2m tonnes.
Calculate the income elasticity of demand for potatoes.

A

20% / -40%
= -0.5
The minus sign indicates that it is an inferior good. The number 0.5 shows that the demand is inelastic

21
Q

What is meant by CROSS-ELASTICITY OF DEMAND?

A

The extent to which the demand for a good changes in response to a change in the price of another good

22
Q

What are the three possibilities of CROSS-ELASTICITY OF DEMAND?

A
  • Complementary goods
  • Substitutes
  • An absence of any discernible demand relationship
23
Q

What is meant by PROFIT?

A

The difference between total sales revenue and total cost of production

24
Q

What is meant by TOTAL REVENUE?

A

The money a firm receives from selling its output

25
Q

What are the main CONDITIONS OF SUPPLY?

A
  • Cost of production
  • Technical progress
  • Taxes
  • Subsidies granted
26
Q

What does an INCREASE in supply look like?

A

A rightward of the supply curve

27
Q

What does a DECREASE in supply look like?

A

A leftward shift of the supply curve

28
Q

What is meant by PRICE ELASTICITY OF SUPPLY?

A

The extent to which the supply of a good changes in response to the change of price

29
Q

What is excess supply?

A

When a firm wish to sell more than consumers wish to buy

30
Q

What is excess demand?

A

When consumers wish to buy more than firms would like to sell

31
Q

What is joint supply?

A

When two different goods can be produced using the same material

32
Q

What is competing supply?

A

When two goods require the exact same material to be made so they can’t both use the same material

33
Q

What is complementary goods?

A

Where different goods are demanded at the same time as each other

34
Q

What is a substitute good?

A

Different goods where they could easily be replacements for each other

35
Q

What is composite demand?

A

Demand for a good which has more than one use

36
Q

What is derived demand?

A

Demand for a good which is an input for the production of another good

37
Q

What is allocative efficiency?

A

When the available economic resources are used to produce the combination of goods/services that match the people’s preferences

38
Q

What is productive efficiency?

A

When the economy cannot produce more of one good without producing less of another

39
Q

What is a merit good?

A

A good which when consumed leads to benefits for the people

40
Q

What is the elasticity if PED = 0

A

Perfectly Inelastic

41
Q

What is the elasticity if PED 0 < PED < 1

A

Inelastic

42
Q

What is the elasticity if PED = 1

A

Unit Elastic

43
Q

What is the elasticity if 1 < PED

A

Elastic

44
Q

What is the elasticity if PED is infinite

A

Perfectly Elastic
