thanks, I'll try and get back to you.

comment Desired portfolio volume
thanks a lot for the answer, however I am more interested in case when the capital $X$ matters. Shall I look into power utility functions?

comment Desired portfolio volume
@quasi: I am not very familiar with utility theory, so can you elaborate on how to apply your advice?

comment How to prove that markets are incomplete under the Stochastic Volatility model?
It might have been discussed in "Foundation of Stochastic Financial Mathematics" by A. Shiryaev

comment Is statistical arbitrage on FX possible?
@maximus_m: google Modern Portfolio theory, and start with a wikipedia page. Also, depending on your technical affinity, you may want to check out that book

comment What distribution to assume for interest rates?
@TheBridge: thanks, but I wonder if there any benchmark distributions for iid interest rates

comment Do people use unbounded interest rate models, and what alternatives exist?
@TalFishman: I would say that interest rate is something which allows you to receive small but positive profit - otherwise you just do not invest there, but maybe I am missing smth.

comment Do people use unbounded interest rate models, and what alternatives exist?
It seems that all these models still allow the interest rate to be unbounded.

Cool, I will take a look of them

comment Do people use unbounded interest rate models, and what alternatives exist?
@Tal Fishman: Nice observation, though most of the models seem to be developed for a kind of "equilibrium" state of economy (like in a mode of growth), so the example with extremely high interest rates won't be enlightened in that models anyway. Btw, thanks for bounty, it worked as appeared.

comment What are some examples of Compound Poisson processes in insurance?
I think it's worth to give a link to the same question on MSE: math.stackexchange.com/questions/62847/…

comment Is there a quantitative finance ranking system for universities?
@sheegaon: +1. Btw, don't you think that the comment post-Docs in finance are extremely rare in the US is a part of answer, not the absence of answer?

comment Is there a quantitative finance ranking system for universities?
Btw, to those who downvote. Don't you want to clarify why are you downvoting. If the reason in off-topic, then maybe you can be also more precise, where is the off-topic? It will be useful not only for me to understand the opinion of community, but hopefully also for other people in the case they would like to ask a question on topic/offtopic boundary.

comment Is there a quantitative finance ranking system for universities?
@richardh: sure, that was the first my idea - but my adviser is not working in the area of finance. I can say, that MIT, ETH Zurich, Cambridge, Oxford, Princeton, Berkeley and Stanford are famous math schools and it's worth to make a PhD/PostDoc there in math. You can also see them in the top of any ranking list for mathematical universities. I just surprised that there is now such a confidence about the mathematical finance.
