Q

list some threats to global economic growth ?

A
  • terrorism
  • disruptions to the oil supply
  • refugees
  • natural disasters
  • trade wars

in africa and asia :

  • not industrialised
  • too reliant on world commodity prices
  • china is moving away from exports than africa could fill this void in but it leaves you very vulnerable.

population growth :
- by 2100 , +3bn in africa mostly
- fall in gdp per capita and standards of living + less jobs
+ new generation of workers helping the economy grow. but may depend on country, e.g. in africa they don’t have the education that will lead to new workers

Q

what are the problems with measurements of GDP ?

Q

how do the HICP and GDP DEFLATOR compare ?

A

as the gdp deflator does not include imports and the hicp does, it means that sometimes they give different values although in general they show the same pattern usually but some things can cause large differ fences.

Q

what is OKUN’s law ?

A

states the relationship between output and unemployment when unemployment falls 1% - growth increases by 3%

  • output growth that is higher than usual is associated with a reduction in the unemployment rate.
  • lower - increase
17
Q

what is the phillips curve ?

A

shows the relationship between unemployment and inflation.

low unemployment leads to an increase in the inflation rate

high unemployment leads to a decrease in the inflation rate

when the inflation rate is stable unemployment is 6%

18
Q

how do we study economic behaviour ?

A

requires us to keep all exovariables constant and then build a model.

19
Q

what models do we look at in the

a. short run
b. medium run
c. long run

A

a. keynsian model / islm model
b. phillips curve / as ad model
c. growth theory / neo classical model / indigenous model

20
Q

the total demand ( Z ) for domestic output is made of 4 components. name them

A

Y = Z = C + I + G + ( X - IM )

C -consumer spending by households
I - gross private domestic investment spending by firms
G - government spending
NX - net exports

21
Q

discuss the component of GDP: consumption ?

A
  • its the primary component
  • includes spending on durables, non durables and services
  • consumption as a share of GDP varies by country
    US: 71% , JAPAN: 60%, UK: 62%
22
Q

discuss the component of GDP: government purchases ?

A
  • transfer payments are not included since its not a part of current production
  • UK: 19%, US: 12%, JAPAN: 21.3%
23
Q

discuss the component of GDP: physical investment ?

A
  • investment that adds to the physical stock of capital.
  • includes inventories or stocks of capital.
  • UK: 17%, US: 20%, JAPAN: 21%
24
Q

discuss the component of GDP: NET EXPORTS ?

A
  • when we have bop deficits we need capital account surplus

- US: -3%, JAPAN: -2.3%, UK: -2%

25
Q

what is the consumption function ?

A
C = C0 + C1 . Yd 
C = C0 + C1Y -C1T

autonomous ( C0 - C1T)

C0 - the level of consumption when income = 0

C0 is > 0 as there is a subsistence level of consumption

C1 - the marginal propensitu to consume = change c / change Yd

consumption increases with disposable income but less than proportional

Yd = disposable income

Yd = Y - T

26
Q

what does the AD equation look like when you put the consumption function into it ?

A

AD = Z = C + I +G

  = C0 - C1T + Ibar + Gbar + C1Y 

the first four components are autonomous, independent of income, Y axis intercept

the last component is an income dependent spending

C0 - C1T + Ibar + Gbar = Abar

AD = Abar + C1Y

27
Q

how do you solve for income equilibrium ?

A

Z = AD = Y

Y = Abar + C1Y

Y - C1Y = Abar

Y = Abar / 1 - C1 OR = 1/1-c1 . ABar

multiplier = 1 / 1 - C1

mpc = C1

it is where the ZZ curve crosses the 45* line

28
Q

how do you calculate changes in autonomous spending?

A

change in Ye = ( 1 + C1 + C1 ^2 ….. ) . change Abar

this is how changes in Abar effects income equilibrium

this helps us explain changes in the business cycle.

29
Q

what is the Savings = Investment condition ?

A

S = Yd - C
= ( Y - T ) - C
= Y - T - C

Z = Y = C + I + G

C + I + G = Y - T - C

I + G - T = Y - T - C

I = S + T - G
= PRIVATE SAVINGS + PUBLIC

30
Q

what is the savings function ?

A

C = C0 + C1 . Yd

S = - C0 + ( 1 - C1 ) . Yd
