  2. 1. Pricing Portfolio Credit Derivatives

    Author : Alexander Herbertsson; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Portfolio credit risk; intensity-based models; dynamic dependence modelling; default contagion; CDS; synthetic CDO tranches; index CDS; k-th-to-default swaps; CDS-correlation; default-correlation; Markov jump processes; multivariate phase-type distributions; matrix-analytic methods;

    Abstract : This thesis consists of four papers on dynamic dependence modelling in portfolio credit risk. The emphasis is on valuation of portfolio credit derivatives. The underlying model in all papers is the same, but is split in two different sub-models, one for inhomogeneous portfolios, and one for homogeneous ones. READ MORE

  4. 2. Taxes, Nudges, and Conformity : Essays in Labor and Behavioral Economics

    Author : Egebark Johan; Peter Fredriksson; Roope Uusitalo; Stockholms universitet; []

    Abstract : This thesis consists of four papers summarized as follows.Do Payroll Tax Cuts Raise Youth Employment? We study whether payroll tax reductions are an effective means to raise youth employment. In 2007, the Swedish employer-paid payroll tax was cut on a large scale for young workers, substantially reducing labor costs for this group. READ MORE

  5. 3. Feasible computation of generalized linear mixed models with application to credit risk modelling

    Author : Md. Moudud Alam; Göran Boström; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Credit risk; cluster correlation; GLMM; large data; two-step pseudo likelihood estimation; defaults contagion; predictive likelihood; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Statistics; Statistik; Statistics; Statistik; Complex Systems – Microdata Analysis;

    Abstract : This thesis deals with developing and testing feasible computational procedures to facilitate the estimation of and carry out the prediction with the generalized linear mixed model (GLMM) with a scope of applying them to large data sets. The work of this thesis is motivated from an issue arising incredit risk modelling. READ MORE

  6. 4. Four applications of stochastic processes : Contagious disease, credit risk, gambling and bond portfolios

    Author : Patrik Andersson; Andreas Nordvall Lagerås; Håkan Andersson; Stewart N. Ethier; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stochastic processes; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Abstract : 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. READ MORE

  7. 5. A neuroimaging perspective on the emotional sleepy brain

    Author : Sandra Tamm; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Sleep has been shown to be important for a number of emotional functions. Brain correlates to the effect of sleep deprivation on emotion have been studied in the last decades and increased amygdala reactivity has been proposed as one possible mechanism. READ MORE
