how to compute: Prob(X-Y-K>0) with copulas

<t>May be it's a problem of notation but I don't see where is dependence on Z (or equivalently Y) in your last expression. In general, it should be Proba(X-Z>0) = where fxz(x,z) - joint density function.If you model your CMS rates as lognormal, then defining x'=X(T)/X(0), y'=Y(T)/Y(0), you'll get fx...

Optimization problem

<t>It is maximum Expected utility. I wonder how would you use Solver to find it...It should be not so complicated to find analytic solution in this case. For 2 assets when one of them is risk-free and assuming power utility function (U(w)=w^p/p) the answer is: c=(mu-r)/(sigma^2*(1-p)), where c is a ...
