This paper introduces the concept of implied Lévy volatility, hereby extending the intuitive Black-Scholes implied volatility into a more general context. More precisely, Lévy implied time and space volatility are introduced and a study of the shape of implied Lévy volatilities is made. Model performance is studied by analyzing delta-hedging strategies for(More)
Recently, coherent optical orthogonal frequency division multiplexing (CO-OFDM) has been considered for the next generation 400-Gb/s long haul data transmission. For long haul transmission systems coherent detection is beneficial compared to direct detection as it provides higher sensitivity. Though CO-OFDM offers a virtually unlimited tolerance against(More)
The paper presents an application of the Variance Gamma distribution to price multivariate derivatives. The paper focuses on the practical implementation of the model in a multivariate setting. Several calibration procedures are discussed and applied to examples. In particular , we focus on the pricing differences for several exotic structures between the(More)
