Finally, for instances with a single pool and attribute, unlimited supplies/pool capacities and fixed demands, the pooling problem is strongly-polynomially solvable (Baltean-Lugojan and Misener, 2018). ...arXiv:1909.12328v1 fatcat:tsrrywz63jfalk5xifvpnrqyqu
Implied volatility expansions allow calibration of sophisticated volatility models. They provide an accurate fit and parametrization of implied volatility surfaces that is consistent with empirical observations. Fine-grained higher order expansions offer a better fit but pose the challenge of finding a robust, stable and computationally tractable calibration procedure due to a large number of market parameters and nonlinearities. We propose calibration schemes for second order expansions thatdoi:10.1137/15m1035215 fatcat:6r3rnwwpezbijbutjaozc4ydp4

We perform a numerical analysis over 12 years of real S&P 500 index options data for both multiscale stochastic and general local-stochastic volatility models. Our methods are validated empirically by obtaining stable market parameters that meet the qualitative and numerical constraints imposed by their functional forms and model asymptotic assumptions.
