We analytically solve the portfolio choice problem in the presence of wash sale constraints in a two-period model with one risky asset. Our results show that wash sale constraints can heavily affect portfolio choice of investors with unrealized losses. The trading behavior of such investors is...

The purpose of this paper is to shed light on some qualitative properties of binomial lattice models by analysing the entire distribution of future values arising from simple bond investment strategies. Our analysis is carried out by first determining the arbitrage free developments of the...

We investigate the possibility of an arbitrage free model for the term structure of interest rates where the yield curve only changes through a parallel shift. We consider HJM type forward rate models driven by a multidimensionalWiener process as well as by a general marked point process. Within...

We establis necessary and sufficient conditions for a linear taxation system to be neutral - within the multi-period discrete time "no arbitrage" model - in the sense that valuation is invariant to the exact sequence of tax rates, realization dates as well as immune to timing options attempting...

De ned contribution pension schemes and life <p> insurance contracts often have a minimum interest rate guar- <p> antee as an integrated part of the contract.

Abstract: Finding the mean-variance eÆcient frontier is <p> a quadratic programming problem with an analytical solu- <p> tion, whenever the portfolio choice is unrestricted. The an- <p> alytical solution involves an inversion of the covariance ma- <p> trix. When short-sale constraints are added to the...</p></p></p></p>

It is a delicate matter to trade spot products and financial derivatives in energy markets. Op-posite to bond and stock markets, the underlying assets are real products and a significant part of the demand for them represents a real need for the products, which can only be substituted away with...
