  1. 1. Scenario Creation for Stress Testing Using Copula Transformation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Gustav Nystedt; [2019]
    Keywords : Stress Testing; Stress Testing Scenarios; Scenario Generation; Copulas; t-copulas; Copula Transformation;

    Abstract : Due to turbulence in the financial market throughout history, stress testing has become a growing part of the risk analysis performed by clearing houses. Events connected to previous crises have increased the demand for prudent risk exposure, and in this thesis we investigate regulators view on how CCPs should construct risk scenarios to meet best practice for stress testing their members’ composite portfolios.

  2. 2. Credit Risk and Asset Correlation Modelling for the Swedish Market: A Comparative Analysis

    University essay from KTH/Matematisk statistik; KTH/Matematisk statistik

    Author : Carl Axel Jönsson; Ludvig Hamilton; [2019]
    Keywords : Credit Risk; Economic Capital; Value-at-Risk; Intra-sector correlation; Inter-sector correlation; Copula; Basel III; Kreditrisk; Ekonomiskt kapital; Value-at-Risk; Intra-sektorkorrelation; Inter-sektorkorrelation; Copula; Basel III;

    Abstract : In order to ensure solvency, financial institutions must evaluate their credit risk exposure and determine how much economic capital is required to hold as a cushion. This thesis compares three factor models, namely Asymptotic Single Risk Factor (“ASRF”), Inter-sector and Intra-sector factor models and evaluates how their different characteristics affect the economic capital outcomes.

  3. 3. The Use of the Copula in Non-Copula Constructions in the Languages of South Asia

    University essay from Uppsala universitet/Institutionen för lingvistik och filologi

    Author : Anna Sjöberg; [2018]
    Keywords : south asia; linguistic area; typology; dravidian; munda; tibeto-burman; indo-aryan; copula;

    Abstract : In this thesis, I explore the use of copulas in non-copula constructions in the languages of South Asia to establish possible genetic and areal tendencies in the distribution. Using materials – language descriptions and data – from Grierson’s Linguistic Survey of India, I examine the phenomenon in 206 languages from four families (Munda, Dravidian, Indo-Aryan and Sino-Tibetan).

  4. 4. Optimal mass transport: a viable alternative to copulas in financial risk modeling?

    University essay from KTH/Matematik (Inst.)

    Author : Johan Orrenius; [2018]
    Keywords : Optimal mass transport; Financial risk; Copulas;

    Abstract : Copulas as a description of joint probability distributions is today common when modeling financial risk. The optimal mass transport problem also describes dependence structures, although it is not well explored. This thesis explores the dependence structures of the entropy regularized optimal mass transport problem. READ MORE

  5. 5. Dependence structure and risk spillovers between real estate and stock markets: An application of VMD based time-varying copula approach

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Ran Tao; Xin Yuan; [2018]
    Keywords : Time varying copula; Variational mode decomposition; Risk spillovers; CoVaR; delta CoVaR;

    Abstract : In this thesis, we combine copulas with the variational mode decomposition (VMD) method to explore the dependence structure between real estate and stock market in three countries, namely China, U.S. and Australia. READ MORE
