This Bachelor's thesis is about the valuation of credit default swaps (CDS) using intensity
models. For this purpose, in a first step, a probabilistic model framework is created in
which such financial instruments can be priced. After a brief introduction to the concept
of credit default, the bonds and CDS traded on the financial market are explained, this
is then transferred (with the respective cash ows) into a mathematical context and first
general valuation formulas are derived. In a second step, the intensity is presented as
a process that, in a sense, quantities the creditworthiness of the company - this can be
deterministic or random. Of course, the latter is more realistic, but for some applications
the former success. With piecewise constant or linear intensities, two parametric
models are set up for deterministic intensities and calibrated to CDS market data. For
random intensities, the so-called CIR++ model is introduced using the CIR process.
After a treatment of the mathematical properties, the difficult calibration of this model
is explained and exemplified. Finally, two methods are presented to simulate the paths
of this process for given parameters - this can be used, for example, for the valuation of
more complex financial instruments.
