Shortfall Risk Approximations for American Options in the multidimensional Black--Scholes Model
We show that shortfall risks of American options in a sequence of multinomial
approximations of the multidimensional Black--Scholes (BS) market converge to
the corresponding quantities for similar American options in the
multidimensional BS market with path dependent payoffs. In comparison to
previous papers we consider the multi assets case for which we use the weak
convergence approach
Limit Theorems for Partial Hedging Under Transaction Costs
We study shortfall risk minimization for American options with path dependent
payoffs under proportional transaction costs in the Black--Scholes (BS) model.
We show that for this case the shortfall risk is a limit of similar terms in an
appropriate sequence of binomial models. We also prove that in the continuous
time BS model for a given initial capital there exists a portfolio strategy
which minimizes the shortfall risk. In the absence of transactions costs
(complete markets) similar limit theorems were obtained in Dolinsky and Kifer
(2008, 2010) for game options. In the presence of transaction costs the markets
are no longer complete and additional machinery required. Shortfall risk
minimization for American options under transaction costs was not studied
before
