Featuring international contributors from both industry and academia, Numerical Methods for Finance explores new and relevant numerical methods for the solution of practical problems in finance. It is one of the few books entirely devoted to numerical methods as applied to the financial field. Presenting state-of-the-art methods in this area, the book first discusses the coherent risk measures theory and how it applies to practical risk management. It then proposes a new method for pricing high-dimensional American options, followed by a description of the negative inter-risk diversification effects between credit and market risk. After evaluating counterparty risk for interest rate payoffs, the text considers strategies and issues concerning defined contribution pension plans and participating life insurance contracts. It also develops a computationally efficient swaption pricing technology, extracts the underlying asset price distribution implied by option prices, and proposes a hybrid GARCH model as well as a new affine point process framework. In addition, the book examines performance-dependent options, variance reduction, Value at Risk (VaR), the differential evolution optimizer, and put-call-futures parity arbitrage opportunities. Sponsored by DEPFA Bank, IDA Ireland, and Pioneer Investments, this concise and well-illustrated book equips practitioners with the necessary information to make important financial decisions.

This monograph deals with the asymptotic behaviour, and in particular the largest fluctuations, of various classes of stochastic differential equations (SDEs) and their discretisations. Equations subject to Markovian switching are also studied, allowing the drift and diffusion coefficients to switch randomly according to a Markov jump process. The assumptions are motivated by the large fluctuations experienced by financial markets which are subjected to random regime shifts. Such results are then applied to a variant of the classical Geometric Brownian Motion (GBM) market model. Moreover it is shown that discrete approximations to these equations, using standard and split-step implicit Euler-Maruyama methods, exhibit asymptotic behaviour which is consistent with their continuous-time counterparts.

The book deals with the asymptotic behaviour of stochastic difference and functional differential equations of Ito type. The equations have a form which make them suitable to model financial markets in which agents use past prices. The main results of the time sysyetms concern the almost sure largest fluctuations of the cumulative returns. These results are robust to the time-discretisation of the process and to the presence of non-linearities in the traders' demand schedules. The conditions for, and dynamics in, a market experiencing a bubble or crash are also described. Numerical methods which both minimise error and preserve the features of the underlying continuous equation are studied and the methods are simulated on computer.

Featuring engaging narratives, this "how-to" book delves into reflection as a concept and provides specific, replicable tools for professional practice. Each chapter draws on a particular school situation demonstrating the value of teacher reflection and describing the nuts and bolts of the process, including protocols for handling many different circumstances.
