1

Q

What is the law of diminishing returns?

A
  • Law of diminishing marginal returns-> There will be a decreas in marginal ( incremntal) output of production process as the amount of single factor of production is incrementally increased while the amounts of all other factors of production stay constant.
    -not all factor inputs are equally suited to producing items leading to lower productivity
    -land labour and capital aren’t perfect subsittues

Q

What does a point inside/ behind the PPF curve indicate?

A

That economy isn’t operating at its full potential level of output. There are unemployed factors of production.

Q

What would cause a move from inside the PPF curve to on the curve? What type of economic growth is it?

A

Reducing spare capacity in the economy ( e.g. putting idle resources to use). Short-term economic growth.

Q

What does a point outside the PPF curve indicate?

A

This level of output is impossible with the current quantity and quality of the factors of production.

Q

How could a country try to reach a point outside the PPF curve and what is this called?

A

-Improving a country’s productive potential by improving the quality or quantity of the factor of production
-long term economic growth

Q

Define PPF

A

This means that, given the available inputs ( e.g. labour), it’s impossible to produce more of one good without decreasing the quantity of another good that’s produced.

Q

How do you show short-term economic growth on a PPF curve?

A

The point will move closer to the PPF curve ( to the right).

Q

What is the trade-off between long-term and short-term when the goods are capital and consumer goods?

A

-Issue of where to invest resources
-There is a trade-off between long-run and short-term economic growth.
-If you choose to produce capital rather than consumer standards of living in the short term will reduce as resources are diverted away from private consumption
-However, in the long term increased investment in capital goods enables more output of consumer goods to be produced increasing the output of the economy compared to if they didn’t make short-term sacrifices.

Q

What is the maximum productive potential of an economy represented by?

A

The maximum productive potential of an economy is represented by any point along the PPF.

17
Q

What does the concept of opportunity cost entail?

A

The production of two more consumer goods incurs an opportunity cost of one capital good.

18
Q

How can economic growth be shown on a PPF?

A

Economic growth can be shown by an outward shift in the PPF.

19
Q

What can cause an outward shift in the PPF?

A

An outward shift can be caused by an increase in the quantity or quality of the factors of production.

20
Q

What does an inward shift of the PPF indicate?

A

An inward shift indicates economic decline, possibly caused by civil war or natural disasters.

21
Q

What does the concept of efficiency mean in relation to the PPF?

A

Any point on the PPF is productively efficient, where factors of production are used to their maximum potential.

22
Q

What is considered inefficient in relation to the PPF?

A

Any point inside the PPF is inefficient, as some factors of production are unemployed or under-employed.

23
Q

What does possible production refer to?

A

Possible production refers to anything under or on the PPF.

24
Q

What is an example of unobtainable production on a PPF?

A

An example of unobtainable production could be point Z because it is beyond the PPF.

25
Q

What should students distinguish between in the context of PPFs?

A

Students should distinguish between capital and consumer goods.

26
Q

How might economic growth be affected by resource allocation?

A

Allocating more resources to the production of capital goods can affect economic growth.
