The stochastic volatility model of Heston (Rev Financ Stud 6(2):327–343, <CitationRef CitationID="CR19">1993</CitationRef>) has found difficulty in describing some of the important features of implied volatility dynamics, leading to a quest for multifactor extensions as well as the incorporation of time-dependent model parameters.

This paper shows that a market price of nominal risk plays an important role in the determinacy of the price of money under a stochastic continuous-time monetary economy. It is presented that a sufficient condition for the determinacy of the price of money is either an exogenously given nominal...

We present a framework of heterogeneous yield curves of agents based on the pricing kernel approach in order to model LIBOR and basis swap rates. Each yield curve may imply different prices of assets but is consistent with swap rates, basis swap rates and foreign exchange rates. We show three...

The purpose of this paper is to demonstrate the powerful and flexible applicability of the Gram-Charlier expansion to pricing of a wide variety of interest rate related products involving interest rate risk and credit risk. In this paper, we develop easily implemented approximations of the...
