In this paper the performance of locally risk-minimizing hedge strategies for European options in stochastic volatility models is studied from an experimental as well as from an empirical perspective. These hedge strategies are derived for a large class of diffusion-type stochastic volatility...

This paper provides a new formal framework to value final-salary defined-benefit pension plans. The valuation framework proposed builds on the familiar idea of discounting future cash flows. Hence, the first step of the valuation process is to find a closed-form solution of the pension fund's...

In this paper, a closed-form solution for future cash flows of defined benefit pension plans is derived. Cash inflows include contributions from active employees and transfer payments from newly recruited employees. Cash outflows involve benefit payments to disabled and retired beneficiaries,...

We introduce a new analytical approach to price American options. Using an explicit and intuitive proxy for the exercise rule, we derive tractable pricing formulas using a short-maturity asymptotic expansion. Depending on model parameters, this method can accurately price options with...

In this paper we construct arbitrage-free market models of stochastic volatility type for one stock, one bank account and a finite family of European call options with various strikes and maturities. We first introduce local implied volatilities and price level as market observables which...

This paper investigates the impact of heterogeneous beliefs of professional investors on the currency options market. Using a unique data set with detailed information on the foreign-exchange forecasts of about 50 market participants over more than ten years, we construct an empirical proxy for...

In the existing literature on barrier options, much effort has been exerted to ensureconvergence through placing the barrier in close proximity to, or directly onto, thenodes of the tree lattice. In this paper we show that this may not be necessary toachieve accurate option price...
