A one dimensional diffusion process $X=\{X_t, 0\leq t \leq T\}$ is observed only when its path lies over some threshold $\tau$. On the basis of the observable part of the trajectory, the problem is to estimate finite dimensional parameter in both drift and diffusion coefficient under a discrete...

We consider a Heston type inflation model in combination with a Hull–White model for nominal and real interest rates, in which all the correlations can be non-zero. Due to the presence of the Heston dynamics our derived inflation model is able to capture the implied volatility skew/smile,...

This paper, which was prepared for presentation in the program of the 2013 International Energy Workshop Conference held on 1921 June in Paris, France is an extensively revised, expanded and slightly retitled version of UNUMERIT Working Paper 2013009. The latter paper has been cited in other...
