Working Papers:
Over the last decade, dividends have become a standalone asset class instead of a mere side product of an equity investment. We introduce a framework based on polynomial jump-diffusions to jointly price the term structures of dividends and interest rates. Prices for dividend futures, bonds, and the dividend paying stock are given in closed form. We present an efficient moment based approximation method for option pricing. In a calibration exercise we show that a parsimonious model specification has a good fit with Euribor interest rate swaps and swaptions, Euro Stoxx 50 index dividend futures and dividend futures options, and Euro Stoxx 50 index options.

In this paper we derive a series expansion for the price of a continuously sampled arithmetic Asian option in the Black-Scholes
setting. The expansion is based on polynomials that are orthogonal with
respect to the log-normal distribution. All terms in the series are
fully explicit and no numerical integration nor any special functions
are involved. We provide sufficient conditions to guarantee convergence
of the series. The moment indeterminacy of the log-normal distribution
introduces an asymptotic bias in the series, however we show numerically
that the bias can safely be ignored in practice.
We present a non-parametric method to estimate the discount curve from market quotes based on the Moore-Penrose pseudoinverse. The discount curve reproduces the market quotes perfectly, has maximal smoothness, and is given in closed-form. The method is easy to implement and requires only basic linear algebra operations. We provide a full theoretical framework as well as several practical applications.
