An overreaction implementation of the coherent market hypothesis and option pricing
Schöbel, Rainer (contributor); Veith, Jochen (contributor) - 2006
Inspired by the theory of social imitation (Weidlich 1970) and its adaptation to financial markets by the Coherent Market Hypothesis (Vaga 1990), we present a behavioral model of stock prices that supports the overreaction hypothesis. Using our dynamic stock price model, we develop a two factor...

Implied Stochastic Volatility Models
Aït-Sahalia, Yacine - 2019
This paper proposes to build "implied stochastic volatility models" designed to fit option-implied volatility data, and … volatility surface to the specification of the stochastic volatility model. We propose and implement parametric and nonparametric … versions of implied stochastic volatility models …
