Non-gaussian Merton-black-scholes Theory

This text introduces an analytically tractable and computationally effective class of non-Gaussian models for shocks (regular Levy processes of the exponential type) and related analytical methods similar to the initial Merton-Black-Scholes approach, which the authors call the Merton-Black-Scholes theory. The authors have chosen applications interesting for financial engineers and specialists in financial economics, real options, and partial differential equations (especially pseudodifferential operators); specialists in stochastic processes should benefit from the use of the pseudodifferential-operators technique in non-Gaussian situations. The authors also consider discrete time analogues of perpetual American options and the problem of the optimal choice of capital, and outline several possible directions in which the methods of the text can be developed further. Taking account of a diverse audience, the work has been written in such a way that it is simple at the beginning and more technical in further chapters, so that it should be accessible to graduate students in relevant areas and mathematicians without prior knowledge of finance or economics.
