    Some Kind Soul -- Need an Article

    I believe that I've found some errors in a paper published by Hull and White, or at the very least, I found some assertions that can be improved upon. The trouble is I'm working off a preprint. The published article itself is $99. Jeez.... wtf! Can some kind soul who's still in college and...

    Quant Jobs in Australia?

    Does that include dodging the seemingly endless list of nature's creatures that wants to kill human life from this Earth? Seems like the list of Australian denizens can be described as "The most (poisonous|cuddly|weird|dangerous|venomous|pretty|cannibalistic|..) on the planet. Hahaha! But...

    Quant Jobs in Australia?

    For what it's worth, I have a friend who made 120k (plus a meager bonus) for being a risk management analyst for a company that specializes in risk management consultancy here in NY. Westpac offered him a sufficiently sweet deal that he picked up and left for Australia. He wouldn't tell me how...

    Can the World Really Be This Bizarre?

    Perhaps the OP did just that, and the internal recruiter instructed him to create a profile on their internal career system. And maybe it's not just this IB. Perhaps one of the big-three ratings agencies also instructed him to fill out their internal profile after they approached him on...

    Can the World Really Be This Bizarre?

    No, I realize. It's pretty obvious when you go to apply for a job at some top tier place and "jobs.somebigname.com" gets redirected to "server.openjobsisourbiz.com". Take a look at what I got this morning for a good laugh. So, yeah. It is what it is, but it's still a necessary thing to deal...

    Can the World Really Be This Bizarre?

    Good guess, but no dice. But even so, considering there's almost 300 majors, putting physics under STEM or Natural Sciences would be really strange. Suppose Emanuel Derman wanted to apply for a job here. How would he enter his educational background? ;-)

    Yield Curve Vs. Swap Curve

    A swap curve is to swaps as a yield curve is to bonds. Swap curves and yield curves represent similar types of data in the same kind of manner. They both give you the yield for a given maturity or tenor on the assumption that each point on the curve represents a contract made *right now*...

    Used Copies of the PRM Handbook (2015)?

    Advice for 40 year old

    I'd like to second yetanotherquant's reply. Your age might be a bit of a problem if you're just now coming into the field, but more importantly is your lack of finance knowledge. You'd probably land a programming job as a quant-developer if you've got good programming skills. I would say the...

    Wikipedia definition of "par value"

    OK, here's my wish list: 1. We need a mobile version of quantnet that makes navigation easier for cellphones. Sometimes I have to "sneak" out of work to make a class, and I completely forget to check the course forum to see if the class is canceled. Running to the 4-train at full speed...

    Andy, even just a simple email will do. Doesn't have to be anything flashy like SMS. Sometimes I have to sneak out the door at 5:30 and don't have time to scour the forums to see if class is canceled. Just any way for the professor to send out class communiques. I've burned 3am oil just to...

    At the risk of sounding like an AOL user, "me too". I second this question. What we really need is a way for professors to send out *emails* to the class telling us things like "class canceled tonight" or "Assignment 3 has been posted". Forums are an inefficient format for that kind of...

    Capstone Project Idea

    How to generate a random number in C++?
