Q

What is supply side ?

A

Relates to changes in the potential output of the economy which is affected by the availability of factors of production

E.g changes in the size of the labour force and the productivity of labour

Q

As output rises what happens to the SRAS curve?

A

Begins to slope upwards which means fitter increase of AD will lead to inflation as well as rising real output

Q

What is the trend growth rate?

A

The rate at which output can grow on a sustained basis,without putting upward or downward pressure on inflation. It reflects the annual average percentage increase in the productive capacity of the economy

Q

Diagram of long run economic growth shifting LRAS to the right

A
18
Q

Where to the causes of long run economic growth lie?(it is in the supply side of the economy)(5)

A

Improvements in tech (investment and technical progress)

Increase in labour force size

Improvements in productivity

Mobility of factors or production

Economic incentives for entrepreneurs and workers they employ

19
Q

Long run growth is affected by the supply side by why does AD have a part to play

A

Firms will only price more goods if there is sufficient demand to absorb the output

20
Q

What are the two main theories of economic growth

A

Neoclassical theory
New growth theory

21
Q

two main theories of economic growth

Neoclassical argument

A

A sustained increase in investment increases economys growth rate temporarily. Ratio of labour to capital goes up

Rate at which labour productivity Improves Is determined by technological progress

However theory does not say how technical progress comes about

22
Q

two main theories of economic growth

New growth theory

A

Replaced neoclassical because it explains how technical progress comes about:

-profit seeking research

-openness to ideas from overseas

-accumulation of human capital

23
Q

What are the costs of economic growth (6) (reduce economic welfare)

A

-uses up finite resources that can’t be replaced (oil and minerals)

-leads to pollution and other forms of environmental degradation

-can destroy local cultures and communities and widen inequalities in distribution of wealth and income

Leads to growth of bid cities-loss of good agricultural land

In early phases raid population increase-more people to feed-more people who are poor

-there are countries with low growth if there are ones with high growth (associate negatives e.g low profits low investment ect ect)

24
Q

Benefits of economic growth(7)

A

Increases standard of living and ppls welfare

Provides new environmentally friendly technologies

May lead to more civilised communities

Route out of poverty

Produces a ‘fiscal dividend’ tax revs that growth generates (tax can be used to correct market failures)

Greater business confidence and increased investment in technology

25
Q

Who benefits and who looses from economic growth

A

W: rich people higher welfare and incomes

L: poor, loss of jobs and increased inequality

Economic growth more harms than benefits to the environment

26
Q

What are the two ways fluctuations happen in the economy?

A

-seasonal
Cyclical over many years

27
Q

What is actual output

A

Level of real output produced in the economy in a particular year

(Don’t confuse with Trend level of output which is what the economy is capable of producing)

27
Q

How long is an economic cycle ?

A

4-12 years

28
Q

Diagram for economic cycle

A
29
Q

Diagram for upswings and downswings in the economic cycle

A
30
Q

What are the explanations for fluctuations in the phases of the economic cycle?

A

-fluctuations in AD

-supply-side factors

-the role of speculative bubbles

-political business cycle theory

-outside shocks hitting the economy

-changes in inventories

-the Marxist explanation

-multiplier/acceleration interaction

-climatic cycles

31
Q

What are the explanations for fluctuations in the phases of the economic cycle?

The role of speculative bubbles

A

Rapid economic growth leads to a rapid rise and speculative bubbles in asset prices

32
Q

What are the explanations for fluctuations in the phases of the economic cycle?

Changes in inventory

A

Firms can also invest in stocks of raw materials and in stocks of finished goods waiting to be sold -key determinant in recessions

As stocks accumulate firms forced to cut production by more than the original fall in demand

33
Q

Diagram for output and employment in economic cycles

A
34
Q

What are output gaps?

A

Show the level of actual real output in the economy either higher or lower than trend level of outoutn

35
Q

Positive output gap

A

The level of actual real output in the economy is greater than the trend output level

36
Q

Negative output gap

A

The level of actual real output in the economy is lower than the trend output level

37
Q

Diagram for negative and positive output gaps in an economic cycle

A
38
Q

When does a gov define an economic cycle as beginning and ending

A

When there are no output gaps
