Q

Law of demand

A

The relationship between price and quantity demanded is inversely proportional. As the price of a good rises, the quantity demanded will usually fall, ceteris paribus (vice versa: as the prices of a good falls, the quantity of demand will usually rise, all things being equal)

A

Y

38
Q

What two relationships can goods have with eachother? (demand)

A

substitute and complementary

39
Q

when goods are related, a change in the _______ of one will result in a change in the _________ of another

A

price, demand

40
Q

what are complements

A

two goods that are typically used or purchased together e.g burgers and fries, or butter and jam

41
Q

What are substitutes

A

Two goods that are similar and are in competition

examples: coke and pepsi

42
Q

what will the increase in price of one substitute good do to the demand of the other good

A

the demand will increase as consumers would want to purchase the cheaper alternative

e.g if coke raises it prices, demand will increase for pepsi.

43
Q

relationship between demand and quantity

A

directly proportional: When demand increases (due to a non-price determinant), the quantity demanded increases at every price point.

44
Q

relationship between price and demand

A

inversely proportional

45
Q

What does change in trends and preferances refer to

A

When goods become more or less popular because of fashion, current events etc. demand is affected

the demand curve may shift to the right or left depending on the trends

46
Q

what does number of consumers refer to

A

It refers to the total number of people in a market who are willing and able to buy a product.

An increase in consumers typically shifts the demand curve to the right, while a decrease shifts it to the left.

example: During the holiday season, more tourists visit a beach town, increasing demand for hotels and restaurants. Once the season ends, the number of consumers drops, decreasing demand.

47
Q

What will the decrease in price of a substitute good do to the demand of another good

A

demand will decrease

e.g- burger king lowers prices so demand will be higher than mcdonalds

48
Q

If the price of one complementary good decreases

A

Demand for the other complementary good increases because the two goods are often used together.

49
Q

If the price of one complementary good increases:

A

Demand for the other complementary good decreases, as the higher cost of one good discourages consumption of both.

50
Q

What does future price expectations refer to for ‘future expectations’

A

if people expect prices of goods and services to increase in the near future, they may decide to purchase more of the goods now.

51
Q

How will the curve shift is the prices are expected to be low?

A

It will shift towards the left as demand will be lower in order to buy the product at a cheaper price later on.

52
Q

what will happen to demand is the future economy is expected to be successful?

A

demand for goods and services will likely increase and the curve will shift to the right

53
Q

Supply definition

A

The quantity of a good or service that producers are willing and able to offer at various prices during a specific time period, ceteris paribus

54
Q

Individual supply

A

The individual supply is the supply of one product from one firm at every price.

55
Q

Market supply

A

The market supply is the sum of all the individual supplies of a product at every price

56
Q

Law of supply

A

There is a DIRECT (or positive) relationship between price and quantity supplied

As the price of a good rises, the quantity supplied will usually rise, ceteris paribus

Higher price: higher supply

57
Q

What is the line in the graph for supply like

A

y=x, like positive

58
Q

What is the line in the graph for demand like

A

y= -x like negative

59
Q

contraction on a demand graph

A

the point moves up the curve (quantity demanded decreases) inverse relation

60
Q

contraction on a supply graph

A

the point moves down the curve (quantity supplied decreases)

61
Q

extension on a demand graph

A

moves down the curve: a rise in quantity demanded

62
Q

extension on a supply graph

A

moves up the curve: quantity supplied increases

63
Q

Change in quantity supplied

A

caused by a change in price of a product, simply moves along the supply curve.

64
Q

Change in supply

A

caused by a non-price determinant: the entire supply curve shifts (price stays the same)

65
Q

What does a rightward / leftward shift (increase& decrease in supply) indicate

A

more is supplied for the same price/ less is for the same price

66
Q

what are the non price determinants for supply

A

Costs of production
Technology
Prices of related goods
Number of producers
Government policies (taxes and subsidies)
Expectations of future prices
sudden unexpected events

67
Q

Whats an example of cost of production affecting supply

A

An increase in the price of flour or wheat will likely decrease the supply of pizza, causing a shift of supply to the left.

If a factor price falls, cost of production falls, production becomes more profitable and the firm produces more vice versa.

68
Q

What does improvements in a firm or industry’s technology do

A

it increases the supply of a good or service by increasing productivity (quantity of output per unit of input)

Supply increases and shifts to the right

69
Q

Example of improvement in technology

A

The implementation of a tractor drastically increases the productivity on farms, thus making production more profitable

70
Q

what is market supply

A

the sum of all the individual supplies of a product

71
Q

How does the number of firms or sellers impact supply?

A

more firms entering the market increase the total supply (rightward shift), while fewer firms reduce supply (leftward shift).

This is due to changes in the aggregate production capacity.

72
Q

What happens to supply when firms expect prices of their products to increase in the near future

A

they might withhold part of their current production from the market (not offering it for sale and storing it) in the hopes of selling at higher price

This leads to fall in supply and a leftward shift

73
Q

What happens to supply when the expectation is that prices of their product will fall

A

supply increases in the present to take advantage of the current higher prices.

rightward shift

74
Q

What is joint supply (price of related goods)

A

When two or more goods are derived from the same product so that it is not possible to produce more of one without producing more of the other.

75
Q

what is competitive supply

A

when the production of two goods uses similar resources and processes. When a supplier produces more of one good it means producing less of the other.

76
Q

What happens to the joint supply good when the price of the other good supplied increases

A

an increase in the price of one leads to an increase in the other, leading to an increase in supply.

77
Q

whats an example of competitive supply

A

If the price of snowboards increases, a ski making firm may switch to snowboard production as its more profitable

78
Q

in competitive supply, the ________ in price of product a leads to the decrease in __________ of b

A

increase, supply

79
Q

in joint supply the _________ in price of product a leads to the ________ in _______of product b

A

increase, increase

80
Q

What is government tax (supply) and what effect does it have

A

Taxes are costs that firms have to pay.

A rise in the rate of an existing tax or the imposition of a new tax will make it more expensive to supply a product and hence reduce supply.

A cut in tax will increase supply.

81
Q

What is a subsidy and what effect does it have on supply.

A

A subsidy is a financial assistance provided by the government to reduce the production costs for firms.

It increases supply by making production more profitable, causing the supply curve to shift rightward.

This encourages firms to produce more at every price level.

82
Q

Examples of supply shocks (analyse how supply moves on the graph and what happens to it)

A

Natural Disasters (e.g., hurricanes, droughts)

These destroy resources or production facilities, causing a negative supply shock.

The supply curve shifts leftward as firms can produce less at every price.

This leads to higher equilibrium prices and lower quantities supplied.

83
Q

example of joint supply (analyse what happens to supply of one)

A

An example of joint supply is wool and lamb, both derived from sheep.

If the price of wool increases, farmers will raise more sheep to sell wool, increasing the supply of lamb as a by-product.

84
Q

the price of a product increases, what will happen to the demand for its complement

A

When the price of a product increases, the demand for its complement decreases (shifts to the left)

85
Q

explain the relationship between demand and change in price

A

Inverse Relationship

86
Q

explain why supply and price are positively related

A

Profit Incentive:

Higher prices make it more profitable for producers to produce and sell the good.

As a result, firms are willing to supply more to maximize their profits.

Higher prices can attract new firms into the market or encourage existing firms to allocate more resources to producing that good, increasing total supply.
