New cards

Market

A place where consumers and producers interact with each other to sell and buy goods/services

2
New cards

Market forces

determining the allocation of scarce resources and the relative price of goods/services

3
New cards

total amount of happiness a consumer derives from a good at any particular level of consumption.

4
New cards

Marginal utility

the added satisfaction that a consumer gets from having one more unit of a good or service.

5
New cards

Normal good

12

13
New cards

the willingness and ability of a consumer to purchase goods at a different price

factors of production

resources or inputs that are used in the production of goods and services. CELLCapital, Enterprise, Land, Labour

20

26

27
New cards

Normative statement

subjective statements that express value judgements, opinions or prescriptions about how things ought to be.

28
New cards

what’s allocative efficiency

an efficient market whereby all goods and services meet the needs and wants of society

29
New cards

Whats Pareto efficiency

If you increase good x then because of the opportunity cost you have to decrease good y

30
New cards

Whos theory was the “tragedy of the commons”

Victorian economist William Foster Lloyd in 1833

31
New cards

what is the tragedy of the commons

The tragedy of the commons is when there is an overconsumption of a particular product/service because rational individual decisions lead to an outcome that is damaging to the overall social welfare (people being selfish and thinking about the short term effects instead of the long run

32
New cards

what are the assumptions of the tragedy of the commons theory

when people make decisions, people take the course of action that maximises their own utilityan example of this would be free-riding, people slowly take more and more until there is nothing left

33
New cards

causes of the tragedy of the commons theory

People choosing short term needs instead of looking at the bigger pictureno formal control over the use of the resourceno barriers to entry

34
New cards

examples

Coffee consumption traffic congestionuse of the rainforest for agriculture

35
New cards

how to stop the tragedy of the commons theoretically

voluntary agreements along the lines suggestedGovernment regulationsClearly defined property rightsTaxes, fines, quotas

36
New cards

PPF curve

A graph that illustrates the possible quantities that can be produced of two products if both depend upon the same finite resources for their manufacture.

37
New cards

assumptions of a ppf curve

an economy chooses to produce these two productsthere are limited resourcestechnology and techniques remain constantall resources(FOP) are fully and efficiently used

38
New cards

Law of increasing opportunity cost

The concept that as an economy moves from one point on the PPF curve to another, the opportunity cost of producing one good increases as more resources are allocated to the production of the other good.

39
New cards

Scarcity

The condition of limited resources relative to unlimited wants, resulting in the need for choices to be made about how resources are allocated.

40
New cards

Opportunity cost

The cost of choosing one option over another, measured by the value of the next best alternative that is foregone.

41
New cards

Free market economics

An economic system characterized by no government intervention in the economic system, including no legislative control over employment, production, or pricing.

42
New cards

Command economics

An economic system characterized by government control, including authority, budget allocation, prioritization, mobilization of resources, and a unique vision, with no profit or private property.

43
New cards

Benefits of free market economics

Contributes to political and civil freedom, economic growth and transparency, and ensures competitive markets.

44
New cards

Benefits of command economics

Low or non-existent unemployment, speed in decision making, equality amongst citizens, and a focus on the workers as opposed to profits.

45
New cards

Problems of free market economics

Subject to manipulation, misinformation, asymmetries of power and knowledge, and fosters wealth inequality.

46
New cards

Problems of command economics

Lack of efficient resource allocation, lack of innovation, and the needs/preferences of society may be ignored due to poor planning.

47
New cards

Factors affecting the outwards shift of a PPF curve

anything to increase FOPinvestment in capital (plants and machinery)discovery of new materialsImmigration of skilled workersimproved education, training and healthcare to lift labour productivityinnovations that increase output per unit and reduce resource wastage

48
New cards

Factors affecting the inward shift of the PPF Curve

anything to decrease FOPDamaging effects of natural disasters such as droughts, tsunamis, floods and earthquakesdestruction of FOP caused by a civil war and other forms of conflict that last few many yearslarge scale of emigrationa trend decline in the productivity caused by a persistent economic recession

49
New cards

draw a specialisation curve and how it works

there has been an improvement in the quantity/quality of FOP that only benefits one of the goods meaning that they are specialised

50
New cards

specialisation factors

Improvements in technology new techniques better trained/skilled labour

51
New cards

Demand Curve

The graphical representation of the relationship between the price charged for a product and the quantity demanded, which is inversely proportionate.

52
New cards

Utility Theory

The theory that examines the satisfaction or benefit that a consumer gains from consuming a product.

53
New cards

Marginal Utility

The additional benefit or satisfaction gained by consuming an extra unit of a product.

54
New cards

Total Utility

The overall level of satisfaction that a consumer obtains from consuming all units of a product.

55
New cards

Plot a graph using the table

y axis = 300→-150x axis 0→7total utility curved marginal utility = demand curve

56
New cards
<p>What happens to TP in this curve?</p>

What happens to TP in this curve?

TP increases as workers are added and then it peaks and starts decreasing as overmanning starts to become a problem.Law of diminishing returns

57
New cards
<p>What happens to AP?</p>

What happens to AP?

Initially rises with the increase in TP but as diminishing returns sets in it’ll fallIf MP>AP then AP will decreaseIf MP<AP then AP will rise

58
New cards
<p>What happens to MP?What is MP?</p>

What happens to MP?What is MP?

MP rises and falls due to the law of diminishing returns, but when MP=0 this will cause TP to peak because the increase in workers no longer means and increase in product. when MP<0 then TP will fallMarginal product is the product that each new worker adds.

59
New cards

What makes the PPF curve curved and not straight?

Its curved because when changing what products they’re producing their skills aren’t 100% interchangeable which causes the graph to curve.

60
New cards

How can a PPF curve be straight?

If all the skills are interchangeable then a straight line can be drawnlaw of contact returns

61
New cards

what does PINTSWC mean

Productivity, indirect tax, number of firms, technology, subsidy, weather, cost of production

62
New cards

What does PASIFIC mean

Price, advertisement, substitutes, income, fashion and trends, interest( subsidies and taxes), complementary
