<t>I think that Bid/Ask spread and other transaction costs is importantpoint of research. In high frequency trading (intraday) they are crucially affect on all models and strategies. Sofisticated modelling here can significantly extend classical schemes where all transactions costs are neglectable.S...

<t>If I'm stuck with a non-Markovian model, my response is change the model slightly toget a Markovian model which has the same sort of qualitative behavior ... since I'm going to calibrate the model exaclty to market prices, the two models will effectively give identical results. >>Pat, The previou...
<t>what are the criteria for a bank to buy off the shelf pricing software versus building its own. >>The criteria are as follows.1. Is there available software in the market?2. The cost efficiency.

<t>For Financial mathematics, We adopt efficient market of hypothesis. i.e all information are reflected on the current stock price. However, the market is not really equilibrium all the time. There sometimes is a quite small arbitrage with short-lived(few minutes). This phenomenon will diappear ver...
<t>Black-Schole model for option pricing, HJM model for interest rate modeling. However for credit risk modeling and illiquidity modeling, there are not benchmark models so far,so future research should be concentrated on credit risk modeling and illiquidity modeling. Do anyone agree or disagree? </t>
Paul, Congratulation! Actually, this forum is very successful! The members include students, practioners, academics,quant., so this forum is a bridge for communication among different background of us coming from every corner of the world.
I think people in the front office has a higher salary than those in the back office. The trader earns money from the bonus, but not really due to arbitrage. The arbitrage exists very rare! one of my friends (a portfolio manager) told me he found "the fools" one time in three years.
