keywords = {local volatility, Cheyette model, Bermudan options},
year = {2020},
abstract = {We show how Markovian projection, together with some clever parameter freezing, can be used to reduce a full‐fledged local volatility interest rate model – such as the Cheyette model – to a “minimal” form in which the swap rate evolved essentially like a dividend‐paying stock. Using a number or numerical examples, we compare such a minimal “poor man's” model to a full‐fledged Cheyette local volatility model and the market benchmark Hall–White one‐factor model. Numerical tests demonstrate that the “poor man's” model is in fact sufficient to price Bermudian interest rate swaptions. The main practical implication of this finding is that – once local volatility, dividend, and short rate parameters are properly stripped from the volatility surface and interest rate curve – one can readily use the widely popular equity derivatives software for pricing exotic interest rate options such as Bermudans.},

abstract = {We introduce a new numerical strategy which we refer to as the Transport‐based Mesh‐free Method (TMM) and discuss its applications to mathematical finance. The proposed method enjoys good accuracy properties similar to those obtained with integration formulas based on the Monte‐Carlo methodology, and in particular enjoys quantitative error bounds which have important implications in applications. In this short review, we outline the main ideas behind this new strategy which relies on techniques of transportation and reproducing kernels. It leads us to an efficient method for numerical simulations while providing some light on the techniques currently developed by the artificial intelligence community. In the applications in the finance industry, our approach provides us with an accurate and fast algorithm, allowing us to compute various types of risk measures. Theoretical arguments are also put forward in order to justify the sharp convergence rates and almost optimal computational times that we observe in our numerical tests and, in addition, typical cases arising in finance applications support our claims. The problem of the curse of dimensionality in finance is briefly discussed.},

abstract = {We use kdb+ and the q language to compare the use of Monte Carlo (MC) and Quasi‐Monte Carlo (QMC) methods for pricing options. Low‐discrepancy Sobol’ sequences are used to price European and Asian options, using both incremental discretization and Brownian‐bridge construction. Results are compared to the deterministic Black–Scholes price for each option type. Analysis was carried out using the time‐series database, kdb+, from Kx. Kdb+ is a hybrid on‐disk and in‐memory columnar database, optimized for the ingestion, storage, and analysis of huge amounts of structured data. Kx software is widely used in the financial industry, for streaming, real‐time, and historical analysis of market data. Our code makes use of the efficient and concise nature of the q language, to mirror the results of Kucherenko and Shah [1].},
