  1. 1. An Attempt at Pricing Zero-Coupon Bonds under the Vasicek Model with a Mean Reverting Stochastic Volatility Factor

    University essay from KTH/Matematik (Avd.)

    Author : Benjamin Neander; Victor Mattson; [2023]
    Keywords : Zero-coupon bond; Vasicek model; Two-factor interest rate model; Stochastic volatility.; Nollkupongobligation; Vasicek model; Räntemodell med två faktorer; Stokastisk volatilitet.;

    Abstract : Empirical evidence indicates that the volatility in asset prices is not constant, but varies over time. However, many simple models for asset pricing rest on an assumption of constancy. READ MORE

  3. 2. Unleashing Profitability: Unraveling the Labor-R&D Nexus in SaaS Tech Firms : An Analysis of the Profitability Dynamics in SaaS Tech Firms through Stochastic Frontier

    University essay from Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Author : prashant Atla; Noräs Salman; [2023]
    Keywords : Employee growth; SaaS Industries; Profitability; Technical efficiency; Stochastic Frontier Analysis; Marginal Product of Labor; Panel data Models;

    Abstract : Background: High-tech's rapid growth and prioritization of expansion over profitability can lead to vulnerability in economic downturns. The SaaS market, a part of the high-tech industry, offers affordable and flexible software solutions but is also susceptible to market volatility. READ MORE

  4. 3. Optimal Capital Structures under the Vasicek Stochastic Interest Rate Model

    University essay from KTH/Matematik (Avd.)

    Author : Oscar Danielson; Tom Hagéus; [2023]
    Keywords : Vasicek model; stochastic interest rate model; optimal capital structures; tax benefits; bankruptcy costs; transaction costs; optimal leverage ratio; optimal debt maturity; Vasicekmodell; stokastisk räntemodell; optimala kapitalstrukturer; skattefördelar; konkurskostnader; transaktionskostnader; optimal belåningsgrad; optimal löptid;

    Abstract : This study applies the Vasicek stochastic interest rate model in order to determine optimal capital structures for listed firms. A Swedish interest rate data set is used to estimate Vasicek model parameter that are reliable and independent of initial start values. READ MORE

  5. 4. Financial Modelling Using Fractional Processes And The Wiener Chaos Expansion

    University essay from KTH/Matematik (Avd.)

    Author : Olof Hummelgren; [2022]
    Keywords : fractional Brownian motion; fBM; applied mathematics; Wiener chaos expansion; Wick product; Hurst parameter; fraktionell Brownsk rörelse; tillämpad matematik; Wiener kaosexpansion; Wickprodukt; Hurstparameter;

    Abstract : The aim of this thesis is to simulate stochastic models that are driven by a fractional Brownian motion process and to apply these methods to financial applications related to yield rate and asset price modelling. Several rough volatility processes are used to model the asset price and yield dynamics. READ MORE

  6. 5. Volatility Forecasting using GARCH Processes with Exogenous Variables

    University essay from KTH/Matematisk statistik

    Author : Ellis Larson; [2022]
    Keywords : Stochastic process; GARCH model; Volatility; Exogenous variables; Evaluation metrics.; GARCH; Volatilitet; Exogena variabler; Evalueringsmetriker.;

    Abstract : Volatility is a measure of the risk of an investment and plays an essential role in several areas of finance, including portfolio management and pricing of options. In this thesis, we have implemented and evaluated several so-called GARCH models for volatility prediction based on historical price series. READ MORE
