    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Nonparametric GARCH model; News Impact Curve; Interest rate volatility; MCMC; Markov Switching; Chinese stock markets; EMU stock markets;

    Sammanfattning : This thesis examines the volatility in the equity and short-term interest-rate markets, and the spillover from the short term interest rate market to the equity market. It consists of three papers and focuses on adapting and proposing models for the estimation and forecasting of financial market volatility. LÄS MER

  3. 7. Essays on Realized Volatility and Jumps

    Författare :Marcus Larsson; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Jumps; Bi-power variation; High frequency data; Realized volatility;

    Sammanfattning : Financial markets sometimes generate significant discontinuities, so called jumps, triggered by large informational shocks and extreme events. In the last decade, there is an increasing interest in financial economics towards modeling these jumps which may have significant consequences for risk management, and portfolio allocation. LÄS MER

  4. 8. Selected Problems in Financial Mathematics

    Författare :Erik Ekström; Johan Tysk; Svante Janson; Lane P. Hughston; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; American options; convexity; monotonicity in the volatility; robustness; optimal stopping; parabolic equations; free boundary problems; volatility; Russian options; game options; excessive functions; superreplication; smooth fit; Matematisk analys; Mathematical analysis; Analys;

    Sammanfattning : This thesis, consisting of six papers and a summary, studies the area of continuous time financial mathematics. A unifying theme for many of the problems studied is the implications of possible mis-specifications of models. Intimately connected with this question is, perhaps surprisingly, convexity properties of option prices. LÄS MER

  7. 10. Definition and validation of requirements management measures

    Författare :Annabella Loconsole; Jürgen Börstler; Björn Regnell; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Requirement; Measures; Volatility; Theoretical Validation; Empirical Validation; Prediction Model; Correlational Study; Subjective Estimation.; Software engineering; Programvaruteknik;

    Sammanfattning : The quality of software systems depends on early activities in the software development process, of which the management of requirements is one. When requirements are not managed well, a project can fail or become more costly than intended, and the quality of the software developed can decrease. LÄS MER
