We consider the hedging problem in a jump-diffusion market with correlated assets. For this purpose, we employ the locally risk-minimizing approach and obtain the hedging portfolio as a solution of a multidimensional system of linear equations. This system shows that in a continuous market, independence and correlation assumptions of assets lead to the same locally risk-minimizing portfolio. ...
We propose a new approach to the pricing and hedging of contingent claims under transaction costs in a general incomplete market in discrete time. Under the assumptions of a bounded mean-variance tradeoff, substantial risk and a nondegeneracy condition on the conditional variances of asset returns, we prove the existence of a locally risk-minimizing strategy inclusive of transaction costs for e...
insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
In [Riesner, M., 2006. Hedging life insurance contracts in a Lévy process financial market. Insurance Math. Econom. 38, 599–608] the (locally) risk-minimizing hedging strategy for unit-linked life insurance contracts is determined in an incomplete financial market driven by a Lévy process. The considered risky asset is not a martingale under the original measure and therefore, a change of measu...
In the context of a locally risk-minimizing approach, the problem of hedging defaultable claims and their Föllmer-Schweizer decompositions are discussed in a structural model. This is done when the underlying process is a finite variation Lévy process and the claims pay a predetermined payout at maturity, contingent on no prior default. More precisely, in this particular framework, the locally ...
We examine Schweizer's (1991) locally risk-minimizing (LRM) hedge approach for hedging a European call in the case when the stock price follows a Poisson jump di usion process with lognormally distributed jump sizes. In contrast to Merton's (1976) hedging strategy where di usion risk is perfectly hedged while jump risk remains un-hedged, the locally risk-minimizing strategy hedges both di usion...
Abstract. We consider a price process model driven by jump-diffusion and study the discretisation and simulation of the related locally risk-minimizing strategy where we focus mainly on hedging Asian and spread options. Using the discretisation scheme and the convergence results on backward stochastic differential equations as studied in Khedher and Vanmaele [17], we show that the locally risk-...
