Q

What is scarcity?

A

Scarcity is the situation in which available resources, or factors of production, are finite, whereas wants are infinite. There are not enough resources to produce everything that human beings need and want.

Q

What is sustainability?

A
  1. Sustainability refers to maintaining the ability of the environment and the economy to continue to produce an satisfy needs and wants into the future.
  2. Sustainability depends crucially on sustainable resource use, referring to the preservation of the environment over time.
  3. The problem of sustainability arises because resources are scarce.

Q

What are free goods?

A

A free good is a good that is not scarce (can be obtained without sacrificing something else) and therefore has 0 opportunity cost.

Example: oxygen in the unpolluted countryside.

17
Q

What are economic goods?

A

An economic good is a good that is scarce, because it is a naturally occurring resource or because it is produced by scarce resources. Economic goods have opportunity costs.

18
Q

What are the 3 basic economic questions?

A
  1. What/how much to produce
  2. How to produce
  3. For whom to produce?
19
Q

What / how much to produce?

A
  1. Decision on the types of goods to produce and how much of each good to produce.
  2. Concerns the allocation of scarce resources.

(e.g. more military equipment or more hospitals?)

20
Q

How to produce?

A
  1. Concerned with the method of production.
  2. Aims to choose the most efficient method of production to make fullest use of scarce resources.
21
Q

For whom to produce?

A
  1. Concern with the distribution of output.
  2. Concerned with the distribution of incomes since the amount of output people can get depends on how much of it they can buy, which in turn depends on the amount of income they have.
22
Q

What are the 3 theoretical economic systems?

A
  1. Free market economy
  2. Command economy
  3. Mixed economy
23
Q

Describe a free market economy

A

allocation of resources based on prices

  1. Resource ownership: private sector
  2. Economic decision-making: private sector
  3. Rationing system: price rationing.
24
Q

Describe a Command Economy

A

allocation of resources based on government decision (based on commands)

  1. Resource ownership: public sector
  2. Economic decision-making: public sector
  3. Rationing system: non-price rationing
25
Q

What is the production possibilities curve (PPC)

A

It represents

  1. all combinations of the maximum amounts of 2 goods that can be produced by an economy
  2. given its resources and technology,
  3. when there is full employment of resources and efficiency in production.
26
Q

What assumptions are made by the PPC?

A
  1. All resources are fully employed
  2. All resources are used efficiently (output is produced by using the fewest possible resources / output is produced at the lowest possible cost)
27
Q

What factors affect the PPC?

A
  1. Quantity of resources
  2. Quality of resources
  3. Technology
28
Q

What does the shape of the PPC mean?

A
  1. Bends outwards to the right: increasing opportunity cost
  • workers are not equally suitable for the production of different goods
  1. Straight-line: Constant opportunity cost
  • the rate at which one good is exchanged for another is constant.
