Asymptotics of forward implied volatility [PDF]
SSRN Electronic Journal, 2015 We prove here a general closed-form expansion formula for forward-start options and the forward implied volatility smile in a large class of models, including the Heston stochastic volatility and time-changed exponential L\'evy models.

Forward implied volatility expansion in time-dependent local volatility models****** [PDF]
ESAIM: Proceedings and Surveys, 2014 We introduce an analytical approximation to efficiently price forward start options on equity in time-dependent local volatility models as the forward start date, the maturity or the volatility coefficient are small.

Spot and forward volatility in foreign exchange [PDF]
Journal of Financial Economics, 2011 This paper investigates the empirical relation between spot and forward implied volatility in foreign exchange. We formulate and test the forward volatility unbiasedness hypothesis, which may be viewed as the volatility analogue to the extensively researched hypothesis of unbiasedness in forward exchange rates.

Volatility transmission and volatility impulse response functions in European electricity forward markets [PDF]
SSRN Electronic Journal, 2008 Using daily data from March 2001 to June 2005, we estimate a VAR-BEKK model and find evidence of return and volatility spillovers between the German, the Dutch and the British forward electricity markets.

Quantum Field Theory of Forward Rates with Stochastic Volatility [PDF]
Physical Review E, 2001 In a recent formulation of a quantum field theory of forward rates, the volatility of the forward rates was taken to be deterministic. The field theory of the forward rates is generalized to the case of stochastic volatility.

Finite dimensional Markovian realizations for stochastic volatility forward rate models [PDF]
Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2004 We consider forward rate rate models of HJM type, as well as more general infinite dimensional SDEs, where the volatility/diffusion term is stochastic in the sense of being driven by a separate hidden Markov process.

Analysing Quantiles in Models of Forward Term Rates
Risks, 2023 The class of forward-LIBOR market models can, under certain volatility structures, produce unrealistically high long-dated forward rates, particularly for maturities and tenors beyond the liquid market calibration instruments.
