Essays on the nonlinear and nonstochastic nature of stock market data [PDF]
The nature and structure of stock-market price dynamics is an area of ongoing and rigourous scientific debate. For almost three decades, most emphasis has been given on upholding the concepts of Market Efficiency and rational investment behaviour.

On the local dynamics of polynomial difference equations with fading stochastic perturbations
We examine the stability-instability behaviour of a polynomial difference equa- tion with state-independent, asymptotically fading stochastic perturbations. We find that the set of initial values can be partitioned into a stability region, an instability

Affine Processes and Application in Finance [PDF]
We provide the definition and a complete characterization of regular affine processes. This type of process unifies the concepts of continuousstate branching processes with immigration and Ornstein-Uhlenbeck type processes.

Strong tightness as a condition of weak and almost sure convergence [PDF]
summary:A sequence of random elements $\{X_j, j\in J\}$ is called strongly tight if for an arbitrary $\epsilon >0$ there exists a compact set $K$ such that $P\left(\bigcap_{j\in J}[X_j\in K]\right)>1-\epsilon$.

Nonparametric estimation of the volatility under microstructure noise: wavelet adaptation
We study nonparametric estimation of the volatility function of a diffusion process from discrete data, when the data are blurred by additional noise. This noise can be white or correlated, and serves as a model for microstructure effects in financial ...

Application of stochastic programming to management of cash flows with FX exposure
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University, 23/06/2006.In this thesis we formulate a model for foreign exchange (FX) exposure management and multi-currency cash management taking into consideration ...

Online Learning for Linearly Parametrized Control Problems
In a discrete-time online control problem, a learner makes an effort to control the state of an initially unknown environment so as to minimize the sum of the losses he suffers, where the losses are assumed to depend on the individual state-transitions ...

Option pricing using hidden Markov models
Includes bibliographical references (leaves 144-149).This work will present an option pricing model that accommodates parameters that vary over time, whilst still retaining a closed-form expression for option prices: the Hidden Markov Option Pricing ...
