I appreciate it.

On the plus side i've finished.

On the minus side I only answered half the questions.

Last shout out for help from any passing individual who feels like being generous.

One more question to go, any chance anyone can solve my problem?

Or is it time for me to drop out of my course and do something easy like History?

Bad news: the rest of the question continous in a similar vein.

It's at times like this I really miss all the econ trips.

>>4232424

I wish I could do either of those things, I truly do.

Econ (more basic maths) question here:

A firm's production function is given by Q=f(S,U)=(2S^1/2 + U^1/2)^2 where Q is output per hour and S and U are skilled and unskilled labour.

v) show that the gradient of any particular isoquant (a line where Q is some fixed constant) is ds/du = -1/2 x (s/u)^1/2

It also leaves no room for being rational or correct.

When talking about price leadership in oligoloply, why would the supply curve of the follower as a fuction of price, S(p), be the rate of change of the profit function Πf'(yf)?

Varian never explicitly states this as a fact, but it's the only way to derive a supply curve that fits in with his terribly explained maths.

>Oh and Πf is the profit function of the follower and yf is the output of the follower etc, I don't know how to do subscript on /sci/.

Speaking as someone who only comes here to ask people smarter than me questions, people smarter than you hate being asked stupid questions.

The problem with your (i'm assuming you're the OP, if not you're far too angry about this for a third party) question is that the two things aren't reliant on each other.

For instance:
Given that the population of Earth is rising very quickly, will we ever know for sure if Charles the 1st and the Duke of Buckingham were gay together?

But for the record, I don't believe human teleportation will ever happen in a feasible way because it's a piece of sci-fi technology

>implying spoilers work on /sci/

>but they don't use empirical date

Literally last week my professor told us about a study of 6,000 german consumers, 96% of whom behaved with rational preferences.

>but they don't use empirical data

No pigs.

I pour all the water onto the floor, now none of the buckets contain poison.

>lives in America

lol

Seriously, why would you call a guy who only needs a bachelors a professor?

>implying a professor set this and not a primary school teacher

Yeah, I just did it and it turns out it was stupidly easy, just what I get for trying to do it last night at 1 am.

Sorry for wasting your time (and thanks for the help).

It's not a problem with the quotient rule, it's just applying it in a situation that isn't just y = f(x), i've learnt shit to exams not actually learning.

>>3956854

Pretty much. I forgot all my maths after A Level.

Oh and I forgot:

[Hint: use quotient rule of differentiation since AC function is defined as AC = AC(Q) = C(Q)/Q and the fact that MC = C'(Q)]

Hooray it's my bi-weekly I-Don't-Understand-Basic-Economics thread.

"For an arbitrary firm, with an arbitrary total cost function C(Q) where Q is the output level show that the gradient of the average cost function can be expressed as:
AC'(Q) = (1/Q)*(MC[Q] - AC[Q])"

Any help?

>mfw i'm reading economics on /sci/ rather than doing actual economics

Also there's so much
>implying this school of thought stuff is relevant to real economics

I guess we just have short terms or something, that or they're trying to do too many modules in one year (we've got Financial Reporting and Management this year).

>>3919110

I guess the short answer is because it's the one we were set.

I think the lecturer said something about it being an American book, and A Level econ being roughly similar to introductory textbooks in the states so we skipped that step as it was assumed knowledge.

Is useful.

We've got 10 weeks to do all of intro to micro and then 6 to do macro. I'm not sure who's doing the schedule but it's hectic.
