Q

How to calculate marginal cost?

A

Total cost(new output level)- Total cost(one unit less than that)

The total cost of producing 100 ice creams is £100 and the Total cost of producing 101 ice creams is £102

£102-£100=2 =MC

Q

What is the law of diminishing marginal utility? How does this affect demand?

A

each additional unit consumed decreases satisfaction of previous unit consumed

From a demand and supply diagram Demand always slope downwards as The more consumption the cheaper price and higher price less demand.

(can work as workers)

31

High employment
Equal balance of payments

32
Q

Why would consumers act irrationally ?

A

Habitual behaviour
Social Norm
Rule of thumb(Middle item)

33
Q

What is bounded rationality ?

A

Limits on self-control(addiction to cigarettes does not maximise consumer utilities)

34
Q

What is Demand?

A

The quantity of goods and services that will be bought at any time given price over a period of time

35
Q

What is a Downwards movement along the demand curve called and a upwards movement?

A

Downwards movement(Expansion)
upwards movement(Contraction)

36
Q

Why do shifts in demand occur?

A

Amount demanded increases or decreases for all prices

37
Q

What affects Demand?

A

Popularity
Income elasticity

38
Q

What is a Normal,Inferior and Luxury good?

A

Normal good(Goods that will be demanded more as income increases)(DVDS)

Inferior good(goods that will be demanded less as income increases)
(Lidl, Aldi, saver menu)

Luxury good(Goods that will be demanded as income increases)(sports cars)

39
Q

What are substitute, complimentary goods, derived demand and composite demand

A

Substitute goods are goods that are alternatives to other such as Fish and red meat

Complimentary goods are goods that impact one another such as salt and fish

Derived demand is the demand for a good or factor of production used in making another good or service such as Wood for Fences

Composite demand is goods with more than one use such as oil

40
Q

What is PED,YED , XED

A

PED(Price elasticity of demand) is how responsive demand is when price increases.

YED(Income elasticity of demand) is how responsive demand is when income increases.

XED(Cross elasticity of demand) is how responsive demand for good A when Price B increases

41
Q

When PED>1, PED<1 what does this mean to elasticity ?

A

PED>1(Elastic with demand)
PED<1(Inelastic with demand)

42
Q

When PED=Infinity, PED=0 what does this mean to elasticity ?

A

PED=Infinity (Perfectly elastic)
PED=0(Perfectly inelastic)

43
Q

What affects PED(Price elasticity of demand)?

A

Substitutes (more goods,More elastic)
Type of good(Habitual, Necessities )
Percentage of income spent(Fridge elastic)
Time(Price over time becomes elastic)

44
Q

How does PED affect Revenue

A

Revenue = Price x quantity
Elastic demand =(Lower price, More revenue)(Higher price, lower revenue)
Inelastic demand(Higher price , more revenue, Lower price lower revenue)

45
Q

How does XED prove that goods are substitutes or complimentary?

A

XED=+(Substitutes are positive higher XED more correlation )

XED=-(complimentary are negative )

XED=0 (independent goods)

46
Q

How is YED useful to Firms and government?

A

YED is useful to firms to predict sales forecasting

Firms may supply multiple different goods to maximise revenue even in booms and recessions

47
Q

What is supply?

A

Supply is the quantity of goods and or services produce to the market at a given price and time

48
Q

Why does Supply shift?

A

A supply curve shifts due to changes in factors such as production costs, technology, government policies, expectations, or the number of suppliers in the market.

49
Q

What factors affect supply?

A

Changes to cost of production
Tech improv
Productivity
Taxes + subsidies
Competitors(Number of suppliers)
Price of other goods

50
Q

What is PES?

A

Price elasticity of supply
How responsive Quantity supplied is regard to price

51
Q

When PES>1,PES<1 what does this mean?

A

PES>1(Elastic supply )
PES<1(Inelastic supply)

52
Q

When PES= Infinity , PES= 0 what does this mean?

A

PES= Infinity (Perfectly elastic)
PES=0(perfectly Inelastic)

53
Q

Firms aim to be elastic as possible
Helps strategic decision making on pricing Strats and production levels

(Limiting consumption, Rising prices eliminates fewer consumers as not many people willing to pay higher prices)

Consumers

59
Q

Where is excess demand and supply on a supply demand diagram when a market is equilibrium ?

A

Top (supply)
Bottom(demand)

60
Q

What is Producer surplus and Consumer surplus?

A

Producer surplus is when they obtain more than they were originally wanted to sell for

Variety
A bigger market

Dissatisfied workers cause absenteeism to increase
People move to less boring jobs creating a problem of high worker turnover and increased hiring/training costs
Increased risk of repetitive strain injuries at work
Some workers receive little training and may not be able to find alternative jobs when out of work – they suffer structural unemployment / occupational immobility
Mass-produced standardised goods may lack variety

65
Q

What is a externality ?

It occurs when there is an external impact on a third party not involved in the economic transaction

Regulation
Providing information (advertising)
Subsidies
taxes

someone docent have full information on the costs and benefits of their decisions
