Pricing First to Default with gaussian copula method

<t>Hi,I'm interested in implementing the gaussian copula method to price first to default contracts. Typically would be on sovereign issuers (5 or 6).I already understood how to generate random numbers with a Normal correlation structure with the use of the cholesky decomposition.But I can’t underst...

First to Default

cap vols: flat vs spot

<t>QuoteOriginally posted by: mutleyI guess you could call it 'vol bootstrapping'.Flat vols: this is the constant vol number you give to all caplets underlying a certain cap such that the sum of their PVs equals the market cap price. Clearly, some will be over priced and others will be underpriced. ...

<t>What I did was to calibrate a, b, c and d to the cap volatilities quoted in the market for different maturities and then use those parameters to obtain vols for other maturities that are not quote in the market. In this way do I get market prices for caplets of different maturities or just some v...

caplet vols

<t>I have made some research on how to imply caplet vols from cap vols and I have encountered two ways of doing so:1)Use the functional form σ(t) = (a+bt)exp(-ct)+d for volatility structure;2)Use caps premiums and used them to imply caplet vols (ex. We have 1y and 2y caps. 1y cap has only one option...

Pricing Range Accrual

<t>Thomssi, could you pls help me with Gary Licht model?He says that the Error Term is negligible because j(ti;1/4) > 4 ( j(ti;1/4) < 1/α ). This is because JIBAR is a quarterly rate witch implies α=1/4.Since Libor rates are annually compounded does this imply that α=1 and that the Error Term won’t ...
