I want to take this kinds of interesting course too.

It's due to professor teaching method
The course itself, for me, is very boring

For risk averse, need to ask FF
I have not much idea on this

i forgot the specifics. but the one the prof gave out was pretty cool.

there were like two cases and u have to pick one.

eg. you have a 50% chance making $10, and 50% chance losing $10
or 20% chance making $25, and 80% chance losing $6.25

if you do the math, the expected value of both scenarioes are the same..... (ie. they're equally good choice)
but most normal joes would pick case 1..... cuz there's less chance of losing + more chance pocketing money

It's very similar to St. Petersburg Paradox then

That is the example when I learnt Risk Averse and Utility concepts =..=

Nah, sleeping bag and cooking utensils price are updated as I saw a few weeks ago, while I was buying my running shoes

I was just not sure about the tents one
Then I just google in ebay
but my 2k budget is a fair guess

Of course, not the top graded of everything
