many reasons. swine flu, recession, hence less people travel.

another major reason is that some companies (british airline, i think) thought the oil price would keep going up when it was $100+  ...

in oz, recession and swine flu have a certain impact on this but it's more due to the competition between the three domestic airlines and other foreign ones like SG :smile_o01:

I don't know
Like say watching a film in front of TV
The first one pick the good spot, sofa with popcorn
Second one pick the 板凳 next to sofa and sit
The last one, has no sofa or chair
has to  ...

interesting~ We are sit in the home now.

Oh really
Those mathematics, lagrange multiplier stuff on demand/supply curve,  return/capital curve = macro?
Aww, then I am into macro more
I mess them up =.=

i hear real analysis is needed to prove things in micro at the phd level.....
but ya..... i dont even know wht real analysis is. :smile_19:

But the zero-sum = idea of hedge
Minimize the risk due to market flucation, right?

ya. thats the idea. but kinda makes you think where the money then come from, no?

Real analysis is analysis in real number
They have complex analysis too

Give you some concepts that I know

Do you know why calculus work?
Do you know the first principle?
Do you know how the first principle is valid?

Analysing the last question is real analysis, one of the area I had studied
First, we studied infremum and supremum ( lower bound and upper bound in daily life words )
then we study series
with these two
we can know the limit of a series ( converge? diverge? or converge with flipping +/- sign that we have no answer )

With series limit, we can extend that to function, like f(x) = 2x^2
Applying the concept, we can conclude the first principal of differerntiation
same to integration
