  1. 1. On estimation in econometric systems in the presence of time-varying parameters

    Författare :Kurt Brännäs; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Econometric systems; time-varying parameters; Kalman filtering; stochastic regressors; unknown transition matrix; robustness; simulation;

    Sammanfattning : Economic systems are often subject to structural variability. For the achievement of correct structural specification in econometric modelling it is then important to allow for parameters that are time-varying, and to apply estimation techniques suitably designed for inference in such models.

  3. 2. Essays on credit markets and banking

    Författare :Ulf Holmberg; Kurt Brännäs; Jörgen Hellström; Peter Englund; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; financial stability; credit market; banking; agent based model; simulations; disequilibrium; clearing market; business cycle; risk; organization; ekonometri; Econometrics; nationalekonomi; Economics;

    Sammanfattning : This thesis consists of four self-contained papers related to banking, credit markets and financial stability.    Paper [I] presents a credit market model and finds, using an agent based modeling approach, that credit crunches have a tendency to occur; even when credit markets are almost entirely transparent in the absence of external shocks.

  4. 3. On Risk Prediction

    Författare :Carl Lönnbark; Kurt Brännäs; Stefan Mittnik; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Finance; Time series; GARCH; Estimation error; Asymmetry; Supply and demand; Econometrics; Ekonometri; ekonometri; Econometrics;

    Sammanfattning : This thesis comprises four papers concerning risk prediction. Paper [I] suggests a nonlinear and multivariate time series model framework that enables the study of simultaneity in returns and in volatilities, as well as asymmetric effects arising from shocks. LÄS MER
