16. Pricing of Some Path-Dependent Options on Equities and Commodities
Sammanfattning : This thesis brings together three papers about the pricing of European and Bermudan path-dependent options, and one paper about the stochastic modelling of a futures price curve. Paper one proposes a fast numerical method to compute the price of so called cliquet options with global floor, when the underlying asset follows the Bachelier-Samuelson model. LÄS MER
17. Four applications of stochastic processes : Contagious disease, credit risk, gambling and bond portfolios
Sammanfattning : This thesis consists of four papers on applications of stochastic processes. In Paper I we study an open population SIS (Susceptible - Infective - Susceptible) stochastic epidemic model from the time of introduction of the disease, through a possible outbreak and to extinction. The analysis uses coupling arguments and diffusion approximations. LÄS MER
18. Variational Methods for Moments of Solutions to Stochastic Differential Equations
Sammanfattning : Numerical methods for stochastic differential equations typically estimate moments of the solution from sampled paths. Instead, we pursue the approach proposed by A. Lang, S. Larsson, and Ch. LÄS MER
19. The capital cost of holding inventory - A real options approach
Sammanfattning : This thesis is based on three scientific papers dealing with costs and financial risks associated with keeping stock. Reasonable cost parameters are important to implement an effective inventory control system, which in turn is one of the key activities in logistics management. All three papers consider a single-level inventory system. LÄS MER
20. Stochastic epidemic models in heterogeneous communities
Sammanfattning : The aim of Paper I is to explain where randomness should be taken into account when modelling epidemic spread, i.e. when a stochastic model is preferable to a deterministic counterpart. LÄS MER
