This paper introduces the Inverse Gamma (IGa) stochastic volatility model with time-dependent parameters, defined by the volatility dynamics dVt = κt.(θt − Vt).dt λt.Vt.dBt. This non-affine model is much more realistic than classical affine models like the Heston stochastic volatility...

In this paper we propose a maximum entropy estimator for the asymptotic distribution of the hedging error for options … maximising Shannon's entropy subject to a set of moment constraints, which in turn yields the value-at-risk and expected … shortfall of the hedging error. The significance of this approach lies in the fact that the maximum entropy estimator allows us …

Replacing equity return (as in the equity risk premium) with returns on an arbitrary contingent claim, we obtain a new class of economic risk premiums to impose upon candidate models. These risk premiums reflect the distance between the physical and risk-neutral moments for asset returns, can be...

This paper suggests a new method of implementing the principle of maximum entropy to retrieve the risk neutral density … previous studies, the method maximizes the entropy measure subject to values of the risk neutral moments. These moments can be … risk neutral density based on the principle of maximum entropy, the benefits of the method that the paper suggests is the …

Entropy pricing applies notions of information theory to derive the theoretical value of options. This paper employs … the maximum entropy formulation of option pricing, given risk-neutral moment constraints computed directly from the … observed prices. First, higher-order moments are used to generate option prices. Then a generalization of Shannon entropy …
