A Note on the Impact of Parameter Uncertainty on Barrier Derivatives
نویسندگان
چکیده
This paper presents a comprehensive extension of pricing two-dimensional derivatives depending on two barrier constraints. We assume randomness on the covariance matrix as a way of generalizing. We analyse common barrier derivatives, enabling us to study parameter uncertainty and the risk related to the estimation procedure (estimation risk). In particular, we use the distribution of empirical parameters from IBM and EURO STOXX50. The evidence suggests that estimation risk should not be neglected in the context of multidimensional barrier derivatives, as it could cause price differences of up to 70%.

In this paper a functional graded material (FGM) thermal barrier coating (TBC) is prepared using Atmospheric Plasma Spraying (APS) method. The FGM layers were deposited by varying the feeding ratio of CYSZ/NiCrAlY and conventional CYSZ on a NiCrALY-coated Inconel 738 substrates. Hot corrosion behavior, bonding strength and the related failure mechanisms of a conventional TBC and a FGM TBC are i...

متن کاملEconomic uncertainty and its impact on costs of consumption and private sector investment in the Iranian economy
The issue of uncertainty and its economic impact is one of the topics that economic researchers have considered in recent years. In conditions of uncertainty, the decision of economic units to produce, consume and invest, etc., is different from normal conditions. This study aims to determine the index of economic uncertainty for Iran according to the channels of its impact on the economy. Ther...
