Q

How is ALLOCATIVE EFFICIENCY acheived?

A

Its achieved through a combination of

  • competition between firms
  • voluntary exchange
30
Q

What can lead to DYNAMIC EFFICIENCY? Why?

A

Competition

Because firms seek to adapt their product and use tech to secure their share of sales.

31
Q

What does competition force firms to do?

A

Continue producing goods/services as long as the MB to consumers is > MC of production to the firm

32
Q

What is a HYPOTHESIS?

A

A statement in an economic model about an economic variable that may be (in) correct

33
Q

What are ECONOMIC VARIABLES?

A

Something measurable that relates to resource use and can have difference values (e.g. wages, prices, hours), used in models to anaylse economic performance/decisions

34
Q

What is POSITIVE ANALYSIS?

A

Anaylsis that:

  • is concerned with WHAT IS
  • involves value-free statements
  • can be checked by facts

…. A positive statement that can be confirmed or negated by facts

  • Based on FACTS/data
  • Cause and effect
  • Objective
35
Q

What is NEGATIVE ANALYSIS?

A

Anaylsis that:

  • is concerned with WHAT OUGHT TO BE
  • involves value judgments
  • can’t be tested/ checked with facts
  • Based on values/opinions
  • Value conclusions
  • Subjective
36
Q

What type of analysis is economics concerned with and why?

A

POSITIVE ANALYSIS - because it measures the costs/benefits of different courses of action

37
Q

What is a PRODUCTION POSSIBILITY FRONTIER?

A

A model that analyse trade offs.

It is a curve show the maximum attainable combinations of two products that may be produced with available resources / current tech

The boundary btw combinations of goods/services that CAN & CAN’T be produced given the available factors of production and state of technology

38
Q

PRODUCTION POSSIBILITY FRONTIER - what is on the x and y axis?

A

Quantity of product X

Quantity of product Y

39
Q

PRODUCTION POSSIBILITY FRONTIER - what points/combinations are ATTAINABLE?

A

Points/combinations ON and BELOW the PPF

Because firm has available resources to produce these combinations.

40
Q

PRODUCTION POSSIBILITY FRONTIER - what points/combinations are EFFICIENT?

A

Points/combinations ON the PPF

Because the firm is using all available resources to full potential, + fewest possible resources are used to produce given output

Max output obtained from available resources

41
Q

PRODUCTION POSSIBILITY FRONTIER - what points/combinations are INEFFICIENT? Why?

A

Points/combinations BELOW the PPF

Because the firm is not operating at capacity - not all available resources are being used

42
Q

PRODUCTION POSSIBILITY FRONTIER - what points/combinations are UNATTAINABLE?

A

Points/combinations ABOVE the PPF

Because the firm does not have the available resources to produce that combination of outputs

43
Q

Why is the PPF bowed outwards from origin?

A

Because CONCAVE, the opportunity cost of producing X in terms of Y depend on where the firm is on the PPF.

Meaning that the PPF can be used to calculate MARGINAL OPPORTUNITY COSTS.

44
Q

In terms of the PPF, what represents economic growth?

A

An outward shift of the PPF curve because economy increases production of goods/services thus raising living standards.

45
Q

What is ECOMOMIC GROWTH?

A

Ability of the economy to produce more goods/services

Expansion of society’s production potential.

  • As economy grows - better tech, better labour, increased capital,
  • As economic resources increase - production possibilities increase and PPF shifts outwards
46
Q

Is it possible for the PPF curve to shift inwards?

A

Yes - if the economy experienced a reduction in its productive resources thus causing output to fall.

47
Q

What 2 economic concepts are used to understand TRADE?

A

PPF

Opportunity Cost

48
Q

What is TRADE?

A

The act of buying/selling a good/service in a market

49
Q

What is ABSOULUTE ADVANTAGE?

A

The ability to produce more of a good/service than other producers with the same amount of resources

Can produce MORE goods/services

50
Q

What is COMPARATIVE/COMPETITIVE ADVANTAGE?

A

The ability to produce a good/service at a lower opportunity cost than other producers.

Can produce goods/services at LOWER OPPORTUNITY COST

51
Q

What is the basis for trade - ABSOLUTE OR COMPARATIVE /COMPETITIVE ADVANTAGE?

A

COMPARATIVE ADVANTAGE/COMPETITIVE

Because individuals/firms are better off if they
(I) specialise in producing goods/services for which they have a competitive advantage, and
(II) gain other goods/services through trade.

52
Q

What is the PRODUCTS MARKET?

A

Markets for goods/services, which households are the demanders and firms the suppliers

53
Q

What are FACTOR MARKETS?

A

Market for FACTORS OF PRODUCTION, where households are the suppliers and firms the demanders

54
Q

What are the 4 FACTORS OF PRODUCTION?

A

Labour
Captial
Natural Resources
Entrepreneurial Ability

55
Q

What is Entrepreneurial Ability?

A

The ability to combine other factors to produce goods/services

56
Q

What is the FREE MARKET?

A

A market with there are few government restrictions on

  • how a good/services is produced/sold
  • how a factor of production is employed
57
Q

What is PRICE MECHANISM?

A

The system in the free market where price changes lead producers to change production in accordance with consumer demand.

58
Q

What is EQUITY?

A

The FAIR distribution of economic benefits btw individuals/societies.

59
Q

What is CORRELATION?

A

The appearance of a relationship - appearance that 2 things are related

60
Q

What is CAUSATION?

A

Direct measurable impact - the direct impact/effect of X on Y.

61
Q

What are MACRO ECONOMICS?

A

Study of the economy as a whole - eg. inflation, unemployment, e/growth

62
Q

What are MICRO ECONOMICS?

A

Study of how households/firms make choices - their interaction with markets

63
Q

What are the key assumptions of a PPF?

A
  • Fixed resources
  • Full employment of resources
  • Fixed technology
  • Two products
64
Q

PPF - when does a company face a trade-off?

A

When it is ON the PPF curve and it wants to produce more of an item.

65
Q

PPF - what is a FREE LUNCH?

A

When a firm is INSIDE the PPF curve and it wants to produce more of an item

66
Q

What does the bowed out curve of the PPF represent?

A
  • Increasing Marginal Opportunity Costs
  • Diminishing returns

Because the more resources already devoted to an activity the smaller the payout of devoting more resources

67
Q

What are CAPITAL GOODS?

A

Goods that are produced/manufactured FACTOR OF PRODUCTION used to produce other goods/services (e.g. building, machines, tools)

68
Q

What are CONSUMPTION GOODS?

A

Goods that are used by consumers and have no future productive used (e.g. food, clothing, cars)

69
Q

When is a country’s future rate of growth likely to be higher? Think PPF, type of goods

A

When ON the PPF curve, the firm is producing more capital goods than consumer goods.
Because more resources devoted to producing goods that have future productive value.

70
Q

Why does production of more captial goods (vs. consumption goods) lead to economic growth?

A

Investment in captial goods (through devotion of more resources);

  • increased capital stock
  • enables the firm to increase future output and expand production possiblities
71
Q

What is CONSTANT OPPORTUNITY COST?

A

Where the opportunity costs remains the same when production of one item is increased.

Opportunity cost may be constant when input resources to produce two products are easily adaptable and therefore can be easily transferred from one product to the other (e.g. pizza vs. calzone)

72
Q

What is INCREASING OPPORTUNITY COST?

A

Where the opportunity cost reflects the req’ment for a firm to sacrifice more and more of one product to increase production of another product.

Evident by the outwardly bowed PPF curve
