We study the valuation of unit-linked life insurance contracts with surrender guarantees. Instead of solving an optimal stopping problem, we propose a more realistic approach accounting for policyholders’ rationality in exercising their surrender option. The valuation is conducted at the...

Cross currency swaps are powerful instruments to transfer assets or liabilities from one currency into another. The market charges for this a liquidity premium, the cross currency basis spread, which should be taken into account by the valuation methodology. We describe and compare two valuation...

This paper derives optimal perfect hedging portfolios in the presence of transaction costs within the binomial model of stock returns, for a market maker that establishes bid and ask prices for American call options on stocks paying dividends prior to expiration.(...)

This paper shows a simple approach to the pricing of options on spread and some arguments in favor of modelling the spread using its two components instead of the spread itself.

This paper provides a simple model of the rescheduling of debt following a sovereign default as a bond exchange.

This paper develops a model and estimate simultaneously the joint dynamics of default-free and defaultable bond term structures.

The introduction of the accounting standards SFAS 123R and IFRS 2 forexecutive stock options has led to an important change. As companies arenow forced to value their stock options at grant date for accounting purposes,the robustness of prices against the choice of certain valuation models...

We study the exponential utility indifference valuation of a contingent claim B in an incomplete market driven by two Brownian motions. The claim depends on a nontradable asset stochastically correlated with the traded asset available for hedging. We use martingale arguments to provide upper and...

We study the dynamic utility indifference value process p(X) when the usefulness of X is evaluated via a dynamic monetary concave utility functional (DMCUF) instead of von Neumann/Morgenstern expected utility. A DMCUF is minus a dynamic convex risk measure. The key tools for our investigations...
