  1. 1. 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

  3. 2. On the Normal Inverse Gaussian Distribution in Modeling Volatility in the Financial Markets

    Författare :Lars Forsberg; Luc Bauwens; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Informatics; computer and systems science; Volatility modeling; inverse Gaussian; normal inverse Gaussian; realized volatility; GARCH; Informatik; data- och systemvetenskap; Informatics; computer and systems science; Informatik; data- och systemvetenskap; statistik; Statistics;

    Sammanfattning : We discuss the Normal inverse Gaussian (NIG) distribution in modeling volatility in the financial markets. Refining the work of Barndorff-Nielsen (1997) and Andersson (2001), we introduce a new parameterization of the NIG distribution to build the GARCH(p,q)-NIG model. LÄS MER

  4. 3. Modeling financial volatility : A functional approach with applications to Swedish limit order book data

    Författare :Suad Elezovic; Xavier de Luna; Gunnar Rosenqvist; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Financial data; functional time series; multivariate generalized least squares; seemingly unrelated autoregression; Statistics; computer and systems science; Statistik; data- och systemvetenskap; ekonometri; Econometrics;

    Sammanfattning : This thesis is designed to offer an approach to modeling volatility in the Swedish limit order market. Realized quadratic variation is used as an estimator of the integrated variance, which is a measure of the variability of a stochastic process in continuous time. LÄS MER

  5. 4. Essays on Time Series Analysis : With Applications to Financial Econometrics

    Författare :Daniel Preve; Rolf Larsson; Bent Nielsen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-Gaussian time series; nonnegative autoregression; robust estimation; strong convergence; realized volatility; volatility forecast; forecast comparison; Diebold-Mariano test; Statistics; Statistik;

    Sammanfattning : This doctoral thesis is comprised of four papers that all relate to the subject of Time Series Analysis.The first paper of the thesis considers point estimation in a nonnegative, hence non-Gaussian, AR(1) model. The parameter estimation is carried out using a type of extreme value estimators (EVEs). LÄS MER
