Title: Introductory Micreconomics Help!!!
Post by: Deleted User on March 23, 2013, 11:19:12 am
For Homework 3 question 6, does anyone know how to do it?

There are four consumers willing to pay the following amounts for a massage:
Sam $28
Cindy $8
Susan $32
Joan $20

There are four masseurs with the following opportunity costs of supply:
John $12
Fred $24
Chan $16
Charles $8

Each masseur has the capacity to produce only one massage.

How many massages should be given to maximise efficiency? What is the maximum possible total surplus?

Thank you in advance.

hey dude i dont have the answer but can you help me out.

for question 2 how do you calculate it? do you have to work out the % ?
Title: Re: Introductory Micreconomics Help!!!
Post by: Deleted User on March 23, 2013, 03:29:36 pm
% change in quantity demanded divided by % change in price.
So for Al, [(50-70)/70]/[(10-5)/5] = -0.29.

Isn't it

-20/5 x 15/120 = -0.5?

You may be right, but I'm just following the lecture notes formula...

I also got -0.5.

I also got -0.29. I did it your way... though lecture notes lead me to a different answer. :-S

Anybody figured out question 6? Still kinda confused about it.

Also, with the MC exam thing starting on Monday, how much does it contribute to our overall grade?

3ab)

4

2b)

To find income elasticity of demand: ΔQ/ΔI x ΣI/ΣQ
ΔQ = change in quantity (in this case referring to change in the quantity she will buy at $20 (this number is stated in Q) because her income is now the same as Fiona's)
     = 20 - 30 = -10
ΔI = change in income
    = 12,500 - 7,500
    = 5,000
ΣI = sum of previous and new income
    = 12,500 + 7,500
    = 20,000
ΣQ = sum of quantity she would have bought with her old income + her new income (at $20)
     = 20 + 30
     = 50

therefore -10/5000 x 20000/50 = 0.8

3a)
when p = 5, Q = 150,000
when p = 10, Q = 100,000

Price elasticity = -50000/5 x 15/250000 = -0.6

0.6<1, therefore inelastic

(btw the price elasticity formula is in the lecture notes)

b) when p = 10, Q = 100,000
when p = 15, Q = 50,000

Price elasticity = -50000/5 x 25/150000 = -1.6

1.6>1, therefore elastic

havent done 4 yet... Also sorry if these are wrong... I'm trying to help out but I may be way off  :P

What's the formula? Sorry, I don't attend the lectures.
Title: Re: Introductory Micreconomics Help!!!
Post by: ferrsal on March 24, 2013, 09:04:27 pm
Price elasticity of demand = ΔQ/ΔP x ΣP/ΣQ

ΔQ - change in quantity
ΔP - change in price
ΣP - sum of both prices
ΣQ - sum of both quantities

Thank you in advance.

Susan gets massaged by Charles, Sam gets massaged by John, Joan gets massaged by Chan, total surplus is $44. I think you try to match up the customers with the highest payments with the masseurs with the lowest opportunity costs; as you would make a loss if Fred were to massage Cindy, she doesn't get a massage.

DISCLAIMER: I think.

Don't get into that habit! 5% is the difference between a P and H3, H3 and H2B, H2B and H2A, H2A and H1!!!!!!! It makes a hella difference.

If the world limit is 1000 words, it means we can write up to 1100 words right?

GUYS where are these homework questions from?!
Title: Re: Introductory Micreconomics Help!!!

Yeah i doubt 100 words make a big difference.

What homework questions are you talking about?
Title: Re: Introductory Micreconomics Help!!!
Post by: MelonBar on March 30, 2013, 06:16:43 pm
^ The ones being talked about in the OP.

Most likely the blue sheet you get given, you can download it from the lms.

If the world limit is 1000 words, it means we can write up to 1100 words right?
Generally there is 10% leeway, but you should check the assignment sheet.
Title: Re: Introductory Micreconomics Help!!!
Post by: Deleted User on March 30, 2013, 08:12:54 pm
The specified word limit is 1000 words. It doesn't mention the 10% leeway, but I assume that this is an unmentioned rule?
Title: Re: Introductory Micreconomics Help!!!
Post by: MelonBar on March 30, 2013, 09:33:27 pm
(for the assignment)

Stupid question but the scale on the price and quantity axes doesn't matter right? like a schematic diagram... I vaguely recall gareth james saying we don't need to calculate areas and stuff so I assume that the scale doesn't matter?

thanks
Title: Re: Introductory Micreconomics Help!!!
Post by: ferrsal on March 30, 2013, 10:01:16 pm
Yeah my tutor said not to worry about scaling, you're not actually using any numerical information to answer your questions.

Is it just me or are the last couple of questions kinda hard  :(
I feel like this assignment would have been a bit more easier if we had a tute about the latest topics before it was due

How can you be over by that much???? CUT IT DOWN! LOL You'll get marked down for sure. Make sure what you're discussing is relevant if it isn't cross it out.
Title: Re: Introductory Micreconomics Help!!!
Post by: Deleted User on April 01, 2013, 03:22:02 pm
It's ALL relevant.  >:(

Are assessors harsh on the word limit though? Would they actually count many words I write?
Title: Re: Introductory Micreconomics Help!!!
Post by: Greatness on April 01, 2013, 05:00:10 pm

Yes, your assessor is your tutor. They will mark to what the lecturers want. It's easy to tell if an essay/report is over the word limit. You can approximate by flipping through it. If it's 'ALL' relevant then only include what is ABSOLUTELY relevant. You want to make sure you're answering the essay question or questions. But if the word limit is 1000 words try to keep it below 1100... It may be a struggle but email your tutor and see what they say. Because you will probably lose marks if it's 1800.
Title: Re: Introductory Micreconomics Help!!!
Post by: Deleted User on April 01, 2013, 07:06:11 pm
Haha, I can assure you that everything I've written is absolutely relevant. I've managed to cut it back to 1500 - still too much?

Title: Re: Introductory Micreconomics Help!!!
Post by: sadboy222 on April 04, 2013, 10:49:47 am
for the first question did you say demand increase for online streaming and demand decrease for dvds ? how about supply?
Title: Re: Introductory Micreconomics Help!!!
Post by: hongs- on April 05, 2013, 11:04:05 pm
In the second question...for 'restriction to advertising'  did any of you say it was a decrease in supply only? or both demand and supply?
I figured advertising can also decrease demand along with supply..but I don't know if thats right..
Title: Re: Introductory Micreconomics Help!!!
Post by: MelonBar on April 06, 2013, 10:14:21 am
Sorry for being a n00b but do we have to do referencing for this assignment?

I guess my ideas are largely from the textbook?

sorry just paranoid..
Title: Re: Introductory Micreconomics Help!!!
Post by: sheepgomoo on April 06, 2013, 11:34:15 pm
@ hongs- to keep it simple i just said that the only effect of restricting advertising was a decrease in demand and went from there. Tbh i dont think there are necessarily right or wrong answers - just your interpretation of the question and how you support your answer.

@MelonBar I put down the textbook just in case :o I was wondering if we needed to reference the lecture slides though, lol.

I am fairly sure that you have to reference the article that you got your idea from (I read this on the online tutor page), so yes, it would be an existing economic event.

Also, jeez you guys are cutting it close, I would personally struggle with doing this on top of Mother's Day stuff :P

terrible stuff
Title: Re: Introductory Micreconomics Help!!!
Post by: Fluttershy on May 12, 2013, 09:32:56 am
please explain how you do part B

1. Pick an event. Read up online on something that sounds interesting or counter-intuitive (it doesn't have to be, it can be completely ordinary, like gold prices increasing, or whatever, but y'know, doing an interesting topic will probably be more exciting than something straightforward, and there's more to write about too).
2. Use that article as a starting point to discuss why the event occurred. e.g. The US Government prevented Microsoft from merging with Company X because it would have generated too much market power in the computer market (I recommend not copying this one, because it's an example in the textbook. You get my point though, right?). Use supply-demand curves wherever applicable (maybe not in the Microsoft example, but if you're analysing something that can be expressed using these curves, go for it!).
3. Submit on Monday, wait for your 30/30 :P

I had graphs for most of the questions, just to stay on the safe side. It really depends on what case study you decided on. Some of them are more difficult to relate to graphs than others.

But yeah, when in doubt, draw a graph. I mean, as long as you're within the word limit, and your graphs are relevant to the question, they can't penalize you for providing too much information, can they?
