With the price fixed at P2 the cuantity demanded is Q1, but the quantity supplied is Q2. The surplus at P2 must be bought up by the government. I think the answer is D. Incidentally I got an A in economics. 20 years ago.

I agree. D is da answer as correctly explaind by astarmathz&phyx (i wish ur name was shortr lol!). Answer 'B' represents da amount spent by da CONSUMERS to keep da price afloat at P2.

hii...

sorry but there was this multiple choice question about the characteristics of money that said:

Which characteristic of money is necessary for it to be accepted as a medium of exchange?
A. it is durable
B. it acts as legal tender
C. it is limited in supply
D. it is portable

my answer was B(acts as legal tender) but in the marking scheme it was C(limited in supply).. ???
i answered B becoz i think if it wasn't a legal tender ppl wud not use it.. but if its not limited in supply (like during inflation) only its value wud fall and ppl wud use it LESS.. :-\

hope any1 cud help me .. thanks  ;)

The reichsmark was legal tender in postwar germany but not accepyed cos it was worthless. For a while cigarettes were a currency. People must value  a currency and for this to happen it must ae limited in supply.

i get the part that country P has a comparitive advantage in producing Z bcoz it can produce Z at a lower opportunity cost that country Q..
but how duz country Q have an absolute advantage in producing Y??
Title: Re: need help in economics AS question
Post by: master786 on April 25, 2009, 02:34:54 pm
bcozcountry P can produce only 1000 while Q produces 1500 ...

i've attached the question ..

thx in advance .. ;)

People in Q can produce 50% more of good Y than people in P but only 25% more of good Z. Q has an absolute adantage in both product but it's advantage is less for good z, so this is p's comparative advantage.

hi evry1 ..  ;)
i have a question about exchange rates .. i'm confused  .. i've attached the part of the question .. but if u need to get a look at the whole question here's the link http://www.freeexampapers.com/FreeExamPapers.com_.php?__lo=QSBMZXZlbC9FY29ub21pY3MvQ0lFLzIwMDcgTm92Lzk3MDhfdzA3X3FwXzIucGRm

when we say that the exchange rate of US$/euro increased .. doesn't this mean that the US$ becomes stronger with respect to the euro, and the euro becomes weaker with respect to the US$ ??!! ???

thats what i think ..
but in this paper the upward arrow shows that the euro becomes stronger and the US$ weaker .. why is it this way??can sum1 please explain
thanks.. :)
Title: Re: need help in economics AS question
Post by: crucio on April 26, 2009, 05:48:14 pm
us $/euro exchange rate increase means that now there are more us$ per euro which means that us $ has depreciated and euro has appreciated. example it increases from $1.5/euro to $2/euro, this means that 1 euro can buy $1.5 but now it can buy $2 hence $ has depreciated 33.33% and euro has appreciated by the same amount

@twilight

If price elasticity of demand is equal to 1, total expenditure must be the same what ever you are changing (either price or quantity)

For the first one, Total expenditure = 12*4000 = 48000
Total expenditure must remain 48000 and quantity demanded must be 20000
Therefore, Price = 48000/20000 = 2.4

oooo okkkkzzzz ... i get it thankssssss  :-*
i tried using the PED formula and it didnt work ..
i gt it now
thanks alot  :D
can u hlp me wid da second?
Title: Re: need help in economics AS question
Post by: Priya on May 31, 2009, 07:12:05 pm
You are welcome... And the second one is basically the same.

unitary price elasticity of demand means ped=1, implying total expenditure should there remain the same.
Total expenditure=25*100000=2500000
Total expenditure should be 2500000 and the firm wants to sell 125000 units
Therefore price= 2500000/125000 = 20

i have a question!!  :-[

"Discuss whether stability in the domestic value of money is essential for the country's well-being"

this question is from may/june 05 paper 2
Stability in value would be upset by inflation. This causes problems with
the efficient working of the price mechanism, international competitiveness
and aspects of redistribution. Price stability can dent expectations and
profits and lead to lack of confidence and stagnation. These effects would
harm economic well-being. This may be shown by inefficiency,
unemployment, lower living standards etc. However the level of harm
depends upon the actual rate of change, whether or not it has been
anticipated and the comparative rate internationally. If these are relatively
favourable the effects may not cause significant instability. A low and
stable level of inflation is thought to encourage production and growth so
absolute stability is not necessary.

Understanding of inflation up to 2 marks
Discussion of harm done by inflation up to 6 marks}to max of
Discussion of circumstances when inflation up to 6 marks}10 marks
may be benign/beneficial

both mcqs are actually based on the inverse relation between price and quantity demanded..... u can do them by the simple inverse proportion formula.

sorry peeps .. can u help wid this 1 too ?
i know that for the TOT to increase any of the following should occur
~increase in export prices with import prices constant
~increase in export prices with decrease in import prices
~constant export prices with decrease in import prices
~increase in export prices and import prices but with the increase in export prices > increase in import prices

this makes the answer to this question between B, C and D

can sum1 help please?
thanks in advance :)
Title: Re: need help in economics AS question
Post by: twilight on June 09, 2009, 02:55:29 pm
and this question too please ..
why is it D not B ??  ??? plz help
thanks
sorry i'm asking too much .. but i hav loads of doubs abt MCQs .. hope any1 can help
Title: Re: need help in economics AS question
Post by: twilight on June 09, 2009, 03:02:09 pm
hey i thaught i help u with TOT qst u posted qst 27. 100 to 120 means tot improve expot price increse mre then import

knw it say terms increse frm 100 to 120 rite and tot=exprt/imprt*100

so let check option A if exprt price decrse by 10% and impot also then terms would b unchanged... do mathmatically 90/90*100=100

option B if exprt incrse by 10% and import decrse by 10% then by tat formula u dont get 120

now C option export increse by 20% and import unchage giving u 120/100*100=120 this is the answere as tot now 120 as said in qst

option again it would worsen ur terms of trade rather then improving it..

thankssss ALOTTTT buddy .. ur gr8 ...  :D :D
Title: Re: need help in economics AS question
Post by: twilight on June 09, 2009, 03:07:26 pm
aa to b truthfull these qustion are really confusing lol normative is value judgment rite..

option B and D look mre appropiate cause it actual fact but D look mre apropaite put it this way as we knw if motorsit have to pay toll they would b at loss cause if they are also not able to afford bus ticket then no choice would b left for then ...confuisng a bit

hmmmm .. ur right .. its too confusing but i get it now  .. its clearer  ... thanks dude!! 8) :D
can i ask more questions?? :-[
Title: Re: need help in economics AS question
Post by: twilight on June 09, 2009, 03:15:00 pm
here's 1 more ..
i know that if the tax is imposed the supply curve wud shift to the left (so it can b either A or B )
The marking scheme shows the answer as A (that is .. the supply becomes more inelastic also)
why duz the elasticity change here?
Title: Re: need help in economics AS question
Post by: Priya on June 09, 2009, 04:37:01 pm
@twilight

There are 2 type of taxes:
(i) Ad Valorem taxes which add a certain percentage on price. (pivots the ss curve to the left)
(ii)Specific taxes which add a fixed amount of money onto costs. (shifts ss curve parallel to the left)

Refer to the attached diagrams
Title: Re: need help in economics AS question
Post by: twilight on June 09, 2009, 04:39:27 pm
ohhhh .. so do u mean that .. since its ad valorem .. then as the price rises the tax rises ?
thanks sweetyyyy

can i ask sum more questions?
Title: Re: need help in economics AS question
Post by: Priya on June 09, 2009, 04:47:33 pm
Yes, since it's a percentage... As price rises, the amount of tax imposed of the good rises, thought the percentage of the tax is still constant.

For example, a 10% tax on the good,
Price - 10, amount of tax - 1
Price - 12, amount of tax - 1.2
Price - 14, amount of tax - 1.4

The increase in tax shifts the ss curve further as opposed to a specific amount of tax.

You can ask more questions, though I cannot say for sure I'll know the answers...

No only the price index. The money supply take time to affect the price index. Typically longer than 6 months.
