In this paper, we provide Poincaré-type upper and lower variance bounds for a function g(X) of a discrete integer-valued random variable (r.v.) X, in terms of the (forward) differences of g up to some ...

We develop an efficient Monte Carlo method for the valuation of financial contracts on discretely realized variance.We work with a general stochastic volatility model that makes realized variance ...
