question 7
its c because they are not asking about the individual but the individual firm ! utility dosent diminish here because many consumers , but individual consumer yes it does! , since the producers produce the same product , a reduction in price of one firm will cause all the consumers to demand from that producer , it wont be a downward slope but a shift , but since they say its a downward slope here we hav to assume its due to imperfect knowledge .

24)
bank gives 9000 out 0f 10 000 , then people deposit 9000 again , bank gives 8100 & so it continues..
untill cash retained by bank = initial cash deposit , credit multiplyer effect. so its 10000/0.1 x 0.9

& of course ans 4 the next question ;)

18:

This is a closed economy with no government !

present equribrium is @ an income of 220
As u know Income = expenditure = output =Aggragate demand(AD)

AD = consumption(C) + Investment ( I)     ## this is of course in a closed economy

IF AD =220   then  C = 3/4 x 220  & I = the rest since its in equilibrium

220 = 165 + I(I= 220-165)
220 = 165 + 55

& to reach full capacity the equlibrium income is:

240 = (3/4 x 240) + I
240 = 180  + 60


now as u can see the Investment incresd from 55 to 60 !

hope u get it

welcome ,

formula hmm ,  i think its

 Injection(i.e 10000)  / (leakages% i.e as decimal )   x (1- cash ratio % )

q11: essential and most important condition of contestable market is that there are low barriers to entry and exit

q20: export is an injection(J), so fall in X has to be offset by rise in J or fall in leakage(W). Hence A but not D because fall in tax rises disposable income, the full rise is not spend here but only part. the rest is removed hence resulting in a smaller multiplier

dude u explained the wronq questions for 11 & 20 i think ? :O

11)
in perfect compition firms are price takers , if they try to make prices they end up making losses , so price wont change, IF marginal cost > MR  it means they are not making profite i.e normal profit , so they reduce quantity back to place where MC=MR (this is also the equilibrum in perfect competion)

20)
ok the Deflationary gap is 4 , which is due to lack of investments,

when investment increases by 4 income rises by 20

4 + increase in consumption = 20

consumption increase = 20-4
then consumtion =16


marginal propensity to consume is the change in consuption to changge in income
change in income = 20
& the consumtion change u got 16

16/20 = 4/5 = 0.8

Hey can u help me with Q15 for this paper

production targeting , because its atomatically decided by market forces than firm , all firms produce the maximum they can , to earn the highest , that is they produce untill MC= MR , no need of target production !
